Issue with UIActivityViewController Not Showing X (formerly Twitter) and Facebook Icons When Sharing Images on iOS 26 Beta
I have installed the iOS 26 Beta on my device and conducted a comprehensive functionality test of my iOS application, which I designed and developed. The application includes a feature that allows users to share images directly to X (formerly Twitter) and Facebook. During testing, I encountered an issue where the icons for X (formerly Twitter) and Facebook do not appear in the share dialog, despite both apps being installed on the device. This issue prevents users from sharing images to these platforms directly from the app. Steps to Reproduce: 1.Install iOS 26 Beta on a compatible device. 2.Ensure that both the X (formerly Twitter) and Facebook apps are installed and logged in on the device. 3.Open the iOS application and navigate to the image sharing feature. 4.Attempt to share an image using the share dialog. 5.Observe that the icons for X (formerly Twitter) and Facebook are missing from the share options. Expected Behavior: The share dialog should display icons for X (formerly Twitter) and Facebook, allowing users to share images directly to these platforms. Actual Behavior: The icons for X (formerly Twitter) and Facebook do not appear in the share dialog, preventing direct sharing to these platforms. Code Implementation: I have not implemented any code to exclude X (formerly Twitter) and Facebook from the share options. Below is the relevant code for controlling the share screen: let activityViewController = UIActivityViewController(activityItems: activityItems, applicationActivities: applicationActivities) let excludedTypes = [ UIActivity.ActivityType.assignToContact, UIActivity.ActivityType.print, ] activityViewController.excludedActivityTypes = excludedTypes activityViewController.completionWithItemsHandler = completion self.present(activityViewController, animated: true, completion: nil) As shown in the implementation, there is no exclusion of X (formerly Twitter) and Facebook, yet their icons do not appear in the share dialog.

The Liquid glass blur effect does not show over the UITabBar as content scrolls underneath.
In iOS26, when using a standalone UITabBar without UITabBarController, the liquid glass blur effect is not applied when scrollable content moves behind the tab bar. However, the blur effect appears correctly when using UITabBarController. Sample Screenshots: When using UITababr When using UITababrController Sample Code: class SimpleTabBarController: UIViewController, UITabBarDelegate { let tabBar = UITabBar() let redItem = UITabBarItem(title: "Red", image: .add, tag: 0) let blueItem = UITabBarItem(title: "Blue", image: .checkmark, tag: 1) override func viewDidLoad() { super.viewDidLoad() view.backgroundColor = .white tabBar.items = [redItem, blueItem] tabBar.selectedItem = redItem tabBar.delegate = self tabBar.translatesAutoresizingMaskIntoConstraints = false let tableContainerView = TableContainerView() view.addSubview(tableContainerView) tableContainerView.translatesAutoresizingMaskIntoConstraints = false NSLayoutConstraint.activate([ tableContainerView.topAnchor.constraint(equalTo: view.topAnchor), tableContainerView.leadingAnchor.constraint(equalTo: view.leadingAnchor), tableContainerView.trailingAnchor.constraint(equalTo: view.trailingAnchor), tableContainerView.bottomAnchor.constraint(equalTo: view.bottomAnchor) ]) view.addSubview(tabBar) NSLayoutConstraint.activate([ tabBar.leadingAnchor.constraint(equalTo: view.leadingAnchor), tabBar.trailingAnchor.constraint(equalTo: view.trailingAnchor), tabBar.bottomAnchor.constraint(equalTo: view.bottomAnchor) ]) }

OTP AutoFill Fails to Distribute Code Across Multiple UITextFields on iOS 26.x
Issue Summary: On iOS 26.0.1 to 26.3, apps using multiple UITextFields for OTP input face a critical issue where the system autofill pastes the entire OTP string into a single text field, usually the focused one, rather than splitting digits across fields. Delegate events like textDidChange: do not trigger consistently on autofill, breaking existing input handling logic. Expected Behavior: OTP autofill should distribute each digit correctly across all OTP UITextFields. Delegate or control events should fire on autofill to enable manual handling. (BOOL)textField:(UITextField *)textField shouldChangeCharactersInRange:(NSRange)range replacementString:(NSString *)string { if (string.length > 1) { // Autofill detected - distribute OTP manually for (int i = 0; i < string.length && i < self.arrayOTPText.count; i++) { UITextField *field = self.arrayOTPText[i]; field.text = [NSString stringWithFormat:@"%c", [string characterAtIndex:i]]; } UITextField *lastField = self.arrayOTPText[string.length - 1]; [lastField becomeFirstResponder]; return NO; } // Handle normal single character or deletion input here return YES; } // // Setup UITextFields - set .oneTimeCode on first field only for (int i = 0; i < self.arrayOTPText.count; i++) { UITextField *field = self.arrayOTPText[i]; field.delegate = self; if (@available(iOS 12.0, *)) { field.textContentType = (i == 0) ? UITextContentTypeOneTimeCode : UITextContentTypeNone; } } What We’ve Tried: Setting textContentType properly. Handling OTP distribution in delegate method. Verifying settings and keyboard use. Testing on multiple iOS 26.x versions. Impact: Major usability degradation during OTP entry. Forces fragile workarounds. Inconsistent autofill reduces user confidence. Request: Request Apple fix OTP autofill to natively support multi-field UITextField OTP input or provide enhanced delegate callbacks for consistent behavior. Did any one face this issue in recent time with iOS 26.0.1 to 26.3 beta version

Keyboard dismissal not animated
Hello, I’ve encountered what seems to be a bug with the keyboard dismissal animation on iOS 26.0 Beta (25A5349a), Xcode Version 26.0 beta 5 (17A5295f). When dismissing the keyboard from a SwiftUI TextField using @FocusState, the keyboard does not animate downward as expected. Instead, it instantly disappears, which feels jarring and inconsistent with system behavior. I am attaching a short video demonstrating the issue. Below is the minimal reproducible code sample: // // ContentView.swift // TestingKeyboardDismissal // // Created by Sasha Morozov on 27/08/25. // import SwiftUI struct ContentView: View { @State private var text: String = "" @FocusState private var isFocused: Bool var body: some View { ZStack { Color.clear.ignoresSafeArea() VStack(spacing: 20) { TextField("Enter text here...", text: $text) .textFieldStyle(.roundedBorder) .focused($isFocused) .padding(.horizontal) HStack { Button("Focus") { isFocused = true } .buttonStyle(.borderedProminent) Button("Unfocus") { isFocused = false } .buttonStyle(.bordered) } } .frame(maxWidth: .infinity, maxHeight: .infinity, alignment: .center) .padding() } .ignoresSafeArea(.keyboard, edges: .bottom) } } #Preview { ContentView() } Steps to reproduce: Run** the app on iOS 26.0 beta 5 (17A5295f). Tap Focus → keyboard appears as expected. Tap Unfocus → keyboard disappears instantly without the usual slide-down animation. Expected result: Keyboard should animate smoothly downwards when dismissed. Actual result: Keyboard instantly vanishes without animation. p.s. we should be really able to upload videos here for demostration

tvOS 18.0 Siri back button behavior bug
On testing my app with tvOS 18, I have noticed the Siri Remote back button no longer provides system-provided behavior when interacting with tab bar controller pages. Instead of moving focus back to the tab bar when pressed, the back button will close the app, as if the Home button was pressed. This occurs both on device and in the Simulator. Create tvOS project with a tab bar controller. Create pages/tabs which contain focusable items (ie. buttons) Scroll down to any focusable item (ie. a button or UICollectionView cell) Hit the Siri Remote back button. See expect behavior below: Expected behavior: System-provided behavior should move focus back to the tab bar at the top of the screen. Actual results: App is closed and user is taken back to the Home Screen. Has anyone else noticed this behavior?

Issue with multiple touches with "Defer System Gestures" on, with iOS
I'm developing a rhythm game for iOS which has four buttons spanning the width of the screen in portrait. I noticed that my testers were having some missed inputs on the buttons on the left and right due to the fact that iOS, by default, tries to ignore accidental touches on the edges of the screen. So I enabled "Defer System Gestures" on the left and right edges, but then quickly started to notice a new, very specific, issue. Description of the issue If you have finger #1 touching and holding anywhere in the middle of the screen, and finger #2 touches on the far right or left edge of the screen just below the horizontal position of finger #1, those touches are inconsistently not recognized. If finger #1 is not present, this issue does not occur. If finger #2 is above or well below finger #1, this issue also does not occur. A dead zone is created on the right and left edges of the screen just below the horizontal position of the first touch. Here is a rough representative example of where touches #1 and #2 need to be for this issue to manifest, in case the text above is not clear. |&amp;#9;&amp;#9;&amp;#9;&amp;#9;| |&amp;#9;&amp;#9;&amp;#9;&amp;#9;| |&amp;#9;&amp;#9;&amp;#9;&amp;#9;| |&amp;#9;&amp;#9;&amp;#9;&amp;#9;| |&amp;#9; 1&amp;#9;&amp;#9;| |&amp;#9;&amp;#9;&amp;#9; 2| |&amp;#9;&amp;#9;&amp;#9;&amp;#9;| It just so happens that this issue is causing major usability problems with my game, as it results in what the user sees as sporadic and inconsistent response when the game calls for two notes to be played at the same time. Steps to recreate the issue Here are the steps if you want to recreate the problem yourself using the "Create New Gesture" pane in "Assistive Touch" (Note that this problem is not specific to the Settings app, but rather is an issue across the system—however this panel defers system gestures and shows where touches are being read, so it is a great place to demonstrate): (1) Go to Settings &gt; Accessibility &gt; Touch &gt; Assistive Touch &gt; Create New Gesture...; (2) With one finger, touch the middle of the screen and hold it through step 3; (3) With a second finger, tap 4 times along the right (or left) edge of the screen in the following places: (a) well above the vertical position of the first touch, (b) just above the vertical position of the first touch, (c) just below the vertical position of the first touch, and (d) well below the vertical position of the first touch; (4) Notice how, more than half the time, touch (c) does not register. I have found that this problem is more replicatable when the first touch is on the lower half of the screen, but I have been able to replicate it when the finger is higher as well, just not as consistently. Here are the four positions described in the steps above: Position a: both touches register |&amp;#9;&amp;#9;&amp;#9;&amp;#9;| |&amp;#9;&amp;#9;&amp;#9;&amp;#9;| |&amp;#9;&amp;#9;&amp;#9;&amp;#9;| |&amp;#9;&amp;#9;&amp;#9; 2| |&amp;#9; 1&amp;#9;&amp;#9;| |&amp;#9;&amp;#9;&amp;#9;&amp;#9;| |&amp;#9;&amp;#9;&amp;#9;&amp;#9;| Position b: both touches usually register |&amp;#9;&amp;#9;&amp;#9;&amp;#9;| |&amp;#9;&amp;#9;&amp;#9;&amp;#9;| |&amp;#9;&amp;#9;&amp;#9;&amp;#9;| |&amp;#9;&amp;#9;&amp;#9;&amp;#9;| |&amp;#9; 1&amp;#9; 2| |&amp;#9;&amp;#9;&amp;#9;&amp;#9;| |&amp;#9;&amp;#9;&amp;#9;&amp;#9;| Position c: only touch 1 registers |&amp;#9;&amp;#9;&amp;#9;&amp;#9;| |&amp;#9;&amp;#9;&amp;#9;&amp;#9;| |&amp;#9;&amp;#9;&amp;#9;&amp;#9;| |&amp;#9;&amp;#9;&amp;#9;&amp;#9;| |&amp;#9; 1&amp;#9;&amp;#9;| |&amp;#9;&amp;#9;&amp;#9; 2| |&amp;#9;&amp;#9;&amp;#9;&amp;#9;| Position d: both touches register |&amp;#9;&amp;#9;&amp;#9;&amp;#9;| |&amp;#9;&amp;#9;&amp;#9;&amp;#9;| |&amp;#9;&amp;#9;&amp;#9;&amp;#9;| |&amp;#9;&amp;#9;&amp;#9;&amp;#9;| |&amp;#9; 1&amp;#9;&amp;#9;| |&amp;#9;&amp;#9;&amp;#9;&amp;#9;| |&amp;#9;&amp;#9;&amp;#9; 2| Is there anything I can do to resolve this behavior? My app requires gesture deferment to be on for the expected experience by the user, and this bug is causing other issues for my testers that kind of need to be resolved before I can confidently release the game.

Liquid Glass clear variant isn't clear
I've been experimenting with Liquid Glass quite a bit and watched all the WWDC videos. I'm trying to create a glassy segmented picker, like the one used in Camera: however, it seems that no matter what I do there's no way to recreate a truly clear (passthrough) bubble that just warps the light underneath around the edges. Both Glass.regular and Glass.clear seem to add a blur that can not be evaded, which is counter to what clear ought to mean. Here are my results: I've used SwiftUI for my experiment but I went through the UIKit APIs and there doesn't seem to be anything that suggests full transparency. Here is my test SwiftUI code: struct GlassPicker: View { @State private var selected: Int? var body: some View { ScrollView([.horizontal], showsIndicators: false) { HStack(spacing: 0) { ForEach(0..<20) { i in Text("Row \(i)") .id(i) .padding() } } .scrollTargetLayout() } .contentMargins(.horizontal, 161) .scrollTargetBehavior(.viewAligned) .scrollPosition(id: $selected, anchor: .center) .background(.foreground.opacity(0.2)) .clipShape(.capsule) .overlay { DefaultGlassEffectShape() .fill(.clear) // Removes a semi-transparent foreground fill .frame(width: 110, height: 50) .glassEffect(.clear) } } } Is there any way to achieve the above result or does Apple not trust us devs with more granular control over these liquid glass elements?

UITabBar Appears During Swipe-Back Gesture on iOS 26 Liquid Glass UI
Hello, While integrating the Liquid Glass UI introduced in iOS 26 into my existing app, I encountered an unexpected issue. My app uses a UITabBarController, where each tab contains a UINavigationController, and the actual content resides in each UIViewController. Typically, I perform navigation using navigationController?.pushViewController(...) and hide the TabBar by setting vc.hidesBottomBarWhenPushed = true when needed. This structure worked perfectly fine prior to iOS 26, and I believe many apps use a similar approach. However, after enabling Liquid Glass UI, a problem occurs. Problem Description From AViewController, I push BViewController with hidesBottomBarWhenPushed = true. BViewController appears, and the TabBar is hidden as expected. When performing a swipe-back gesture, as soon as AViewController becomes visible, the TabBar immediately reappears (likely due to A’s viewWillAppear). The TabBar remains visible for a short moment even if the gesture is canceled — during that time, it is also interactable. Before iOS 26, the TabBar appeared synchronized with AViewController and did not prematurely show during the swipe transition. Tried using the new iOS 18 API: tabBarController?.setTabBarHidden(false, animated: true) It slightly improves the animation behavior, but the issue persists. If hidesBottomBarWhenPushed is now deprecated or discouraged, migrating entirely to setTabBarHidden would require significant refactoring, which is not practical for many existing apps. Is this caused by a misuse of hidesBottomBarWhenPushed, or could this be a regression or design change in iOS 26’s Liquid Glass UI?

UIViewRepresentable never dismantled on deletion (MEMORY LEAK)
I have find out that a UIViewRepresentable, even with a simples UIView, seems to never be dismantled when deleted from a ForEach and this can cause serious crashes. In the following example you can observe this behavior by deleting a row from the list. The dismantleUIView function of SomeUIViewRepresentable or the deinit of SomeUIView are never called. Has anyone faced this and found a solution for it? I have also filled a Feedback: FB11979117 class SomeUIView: UIView {     deinit {         print(#function)     } } struct SomeUIViewRepresentable: UIViewRepresentable {     func makeUIView(context: Context) -> SomeUIView {         let uiView = SomeUIView()         uiView.backgroundColor = .systemBlue         return uiView     }     func updateUIView(_ uiView: SomeUIView, context: Context) { }     static func dismantleUIView(_ uiView: SomeUIView, coordinator: Coordinator) {         print(#function)     } } struct Model: Identifiable {     let id = UUID() } struct ContentView: View {     @State var models = [Model(), Model(), Model(), Model(), Model()]     var body: some View {         List {             ForEach(models) { _ in                 SomeUIViewRepresentable()             }             .onDelete {                 models.remove(atOffsets: $0)             }         }     } }

UIKit crash on app built with Xcode 26 but run on iOS 18.X
An app built on Xcode 26 (beta4) presents various UIViewCOntrollers. Presentation of any UIViewController that contains a UIToolbar leads to a UIKit crash when run on an iOS 18.5 device, it does not crash when run on iOS 26. The exception logged: *** Terminating app due to uncaught exception 'NSInvalidUnarchiveOperationException', reason: 'Could not instantiate class named TtGC5UIKit17UICoreHostingViewVCS_21ToolbarVisualProvider8RootView because no class named TtGC5UIKit17UICoreHostingViewVCS_21ToolbarVisualProvider8RootView was found; the class needs to be defined in source code or linked in from a library (ensure the class is part of the correct target)' Anyone else seen this?

Popovers are broken on Catalyst builds without portrait support
On macOS 15.2, any Mac Catalyst project that does not support portrait iPad orientation will no longer be able to successfully show the contents of any popover controls. This does not appear to be a problem on earlier versions of macOS and it only affects Mac Catalyst builds, not "Designed for iPad" builds. STEPS TO REPRODUCE Create a project that utilizes Mac Catalyst. Create a simple button that shows a popover with simple content. Remove Portrait as a supported orientation. Run the project on macOS 15.2 as a Mac Catalyst build. Note that the content inside the popover is not shown the popover is shown. Run the project as Designed for iPad. Note that the popover content shows correctly.

hidesBottomBarWhenPushed is bugged on iOS 26
I am using a common UI pattern: UITabBarController as window root, each tab with a separate UINavigationController stack. I want the (bottom!) tab bar to be only visible when the user is at the root of the app and hide it when a detail page is opened. To do that, I used hidesBottomBarWhenPushed on any view controller that would be pushed on my navigation stacks and that worked fine in the past. But with iOS 26, I am seeing several issues: On iOS where when the bottom tab bar is used, when in a details page and navigating back, the tab bar becomes fully visible immediately instead of slowly animating in as it has been in the past. This is particular visible and annoying when using the "swipe to go back" gesture On iPad, the situation is even worse: On iPadOS 18, the tab bar appeared in the navigation controller's navigation bar - no matter if hidesBottomBarWhenPushed was set or not - fine. But now, with iPadOS 26, this top tab bar disappears when a child is pushed. Not only that, it disappears abruptly, without animation, and the Liquid Glass effect on the UIBarButtonItems is broken as well. There is no transition whatsoever, buttons are simply replaced with the new UIBarButtonItems of the pushed view controller once it became fully visible. It gets even worse when swipe-back navigating on iPadOS: As soon as the back transition starts, the tab bar becomes visible again (without animation), covering the title (view) of the UINavigationController. If the swipe-back transition is not completed the tab bar suddenly stays visible When the swipe-back transition is interrupted close to the end of the transition and it goes back to the pushed view controller, the top UIBarButtonItems are showing a visual glitch where the content (text or icon) stays on the area where the tab bar is, while their container (the glass effect) are on the vertically aligned to the title view. I am surprised that I have not found any similar reports of these problems, so I am wondering if I am doing anything wrong or using hidesBottomBarWhenPushed simply isn't recommended or supported any more.

SwiftUI navigationTransition(.zoom) glitches during interactive swipe-back
Hi everyone 👋 I’m fairly new to iOS development and I’ve been stuck on a SwiftUI issue for a while now, so I’m hoping someone here can spot what I’m doing wrong. I’m using navigationTransition(.zoom) together with matchedTransitionSource to animate navigation between views. The UI consists of a grid of items (currently a LazyVGrid, though the issue seems unrelated to laziness). Tapping an item zooms it into its detail view, which is structurally the same view type and can contain further items. All good expect that interactive swipe-back sometimes causes the item to disappear from the grid once the parent view is revealed. This only happens when dismissing via the drag gesture; it does not occur when using the back button. I’ve attached a short demo showing the issue and the Swift file containing the relevant view code. Is there something obvious I’m doing wrong with navigationTransition / matchedTransitionSource, or is this a known limitation or bug with interactive swipe-back? Thanks in advance. import SwiftUI struct TestFileView: View { @Namespace private var ns: Namespace.ID let nodeName: String let children: [String] let pathPrefix: String private func transitionID(for childName: String) -> String { "Zoom-\(pathPrefix)->\(childName)" } private let columns = Array(repeating: GridItem(.flexible(), spacing: 12), count: 3) var body: some View { ScrollView { VStack(alignment: .leading, spacing: 12) { Text(nodeName) .font(.title.bold()) .padding(.bottom, 6) LazyVGrid(columns: columns, spacing: 12) { ForEach(children, id: \.self) { childName in let id = transitionID(for: childName) NavigationLink { TestFileView( nodeName: childName, children: childrenFor(childName), pathPrefix: "\(pathPrefix)/\(childName)" ) .navigationTransition(.zoom(sourceID: id, in: ns)) } label: { TestFileCard(title: childName) .matchedTransitionSource(id: id, in: ns) } .buttonStyle(.plain) } } } .padding() } } private func childrenFor(_ name: String) -> [String] { switch name { case "Lorem": return ["Ipsum", "Dolor", "Sit"] case "Ipsum": return ["Amet", "Consectetur"] case "Dolor": return ["Adipiscing", "Elit", "Sed"] case "Sit": return ["Do", "Eiusmod"] case "Amet": return ["Tempor", "Incididunt", "Labore"] case "Adipiscing": return ["Magna", "Aliqua"] case "Elit": return ["Ut", "Enim", "Minim"] case "Tempor": return ["Veniam", "Quis"] case "Magna": return ["Nostrud", "Exercitation"] default: return [] } } } struct TestFileCard: View { let title: String var body: some View { VStack(alignment: .leading, spacing: 8) { Image(systemName: "square.stack.3d.up") .symbolRenderingMode(.hierarchical) .font(.headline) Text(title) .font(.subheadline.weight(.semibold)) .lineLimit(2) .minimumScaleFactor(0.85) Spacer(minLength: 0) } .padding(12) .frame(maxWidth: .infinity, minHeight: 90, alignment: .topLeading) .background(.thinMaterial, in: RoundedRectangle(cornerRadius: 14, style: .continuous)) } } private struct TestRoot: View { var body: some View { NavigationStack { TestFileView( nodeName: "Lorem", children: ["Ipsum", "Dolor", "Sit"], pathPrefix: "Lorem" ) } } } #Preview { TestRoot() }

Increase Contrast reduces List selection contrast in dark appearance in SwiftUI NavigationSplitView
[Submitted as FB22200608] With Increase Contrast turned on, the selected row highlight in a List behaves inconsistently between light and dark appearance on iPad. In light appearance the blue selection highlight correctly becomes darker, but in dark appearance it becomes lighter instead. The text contrast ratio drops from about 3:1 to about 1.5:1, well below accessibility guidelines. This reproduces both in the simulator and on a physical device. The sample uses a standard SwiftUI List inside NavigationSplitView with built-in selection styling. No custom colors or styling are applied. REPRO STEPS Create a new Multiplatform project. Replace ContentView with code below. Build and run on iPad. Select an item in the list. Turn on Dark appearance (Cmd-Shift-A in Simulator). Turn on Increase Contrast (Cmd-Control-Shift-A in Simulator). Observe the selected row highlight. ACTUAL In light appearance, the blue selection highlight becomes darker when Increase Contrast is on, improving contrast as expected. In dark appearance, the blue selection highlight becomes lighter when Increase Contrast is on, reducing contrast between the selection background and the white text. EXPECTED Increase Contrast should consistently increase contrast. In dark appearance, the selection highlight should become darker—or otherwise increase contrast with the foreground text—not lighter. SAMPLE CODE struct ContentView: View { @State private var selection: String? var body: some View { NavigationSplitView { Text("Sidebar") } content: { List(selection: $selection) { Text("Item One") .tag("One") Text("Item Two") .tag("Two") } } detail: { if let selection { Text(selection) } else { Text("Select an item") } } } } SCREEN RECORDING CONTACTS The Contacts app behaves correctly. When Increase Contrast is turned on, the selection blue becomes darker, improving contrast. PASSWORDS The Passwords app, however, exhibits the issue. With Increase Contrast turned on, the selection blue becomes lighter instead of darker, reducing contrast.

Implicit list row animations broken in Form container on iOS 26 beta 3
[Submitted as FB18870294, but posting here for visibility.] In iOS 26 beta 3 (23A5287g), implicit animations no longer work when conditionally showing or hiding rows in a Form. Rows with Text or other views inside a Section appear and disappear abruptly, even when wrapped in withAnimation or using .animation() modifiers. This is a regression from iOS 18.5, where the row item animates in and out correctly with the same code. Repro Steps Create a new iOS App › SwiftUI project. Replace its ContentView struct with the code below Build and run on an iOS 18 device. Tap the Show Middle Row toggle and note how the Middle Row animates. Build and run on an iOS 26 beta 3 device. Tap the Show Middle Row toggle. Expected Middle Row item should smoothly animate in and out as it does on iOS 18. Actual Middle Row item appears and disappears abruptly, without any animation. Code struct ContentView: View { @State private var showingMiddleRow = false var body: some View { Form { Section { Toggle( "Show **Middle Row**", isOn: $showingMiddleRow.animation() ) if showingMiddleRow { Text("Middle Row") } Text("Last Row") } } } }

SwiftUI navigationTransition Regression on iOS 26 (Source View Disappears + Flicker/Misaligned Geometry)
Summary I’m experiencing two issues with SwiftUI’s navigationTransition(.zoom) on iOS 26.0 and 26.1 that break previously smooth transitions. These issues appear both on real devices and Simulator. The same code works correctly on iOS 18. Issue 1 - Source View Disappears After Drag-Dismiss When using .navigationTransition(.zoom(sourceID:..., in:...)), the source view disappears completely after the transition finishes. This only happens when the detail view is dismissed via drag (interactive dismiss). When the view is dismissed by tapping the back button, the source view remains visible as expected. Reproduced on: iOS 26.0, iOS 26.0.1 (17A400), iOS 26.1 (Simulator + physical device) Issue 2 — Flickering and Geometry Mismatch During Transition Compared to iOS 18 behavior, the outgoing view and incoming view no longer share consistent geometry. Current behavior on iOS 26: The disappearing view flickers during the drag-dismiss interaction. The source and destination views no longer align geometrically. Instead of smoothly morphing as in previous iOS versions, the two views briefly overlap incorrectly before applying the zoom animation. Expected (iOS 18) behavior: Matched geometry between source and destination. Smooth, stable zoom transition with no flickering. // // ContentView.swift // DummyTransition // // Created by Sasha Morozov on 12/11/25. // import SwiftUI struct RectItem: Identifiable, Hashable { let id: UUID = UUID() let title: String let color: Color } struct ContentView: View { @Namespace private var zoomNamespace private let items: [RectItem] = [ RectItem(title: "Red card", color: .red), RectItem(title: "Blue card", color: .blue), RectItem(title: "Green card", color: .green), RectItem(title: "Orange card", color: .orange) ] var body: some View { NavigationStack { ScrollView { VStack(spacing: 16) { ForEach(items) { item in NavigationLink { DetailView(item: item, namespace: zoomNamespace) .navigationTransition( .zoom(sourceID: item.id, in: zoomNamespace) ) } label: { RoundedRectangle(cornerRadius: 16) .fill(item.color.gradient) .frame(height: 120) .overlay( Text(item.title) .font(.headline) .foregroundStyle(.white) ) .padding(.horizontal, 16) .matchedTransitionSource(id: item.id, in: zoomNamespace) } .buttonStyle(.plain) } } .padding(.vertical, 20) } .navigationTitle("Cards") } } } struct DetailView: View { let item: RectItem let namespace: Namespace.ID var body: some View { ZStack { item.color Text(item.title) .font(.largeTitle.bold()) .foregroundStyle(.white) } .ignoresSafeArea() .navigationTitle("Detail") .navigationBarTitleDisplayMode(.inline) } } #Preview { ContentView() } Testing Environment MacBook Pro (2023, M2 Pro, 16 GB RAM) macOS 26.2 Beta (25C5031i) Xcode: Version 26.0.1 (17A400) Devices tested: Simulator (iOS 26.0 / 26.1) Physical device (iPhone 16) running iOS 26.1

Issue with UIActivityViewController Not Showing X (formerly Twitter) and Facebook Icons When Sharing Images on iOS 26 Beta
I have installed the iOS 26 Beta on my device and conducted a comprehensive functionality test of my iOS application, which I designed and developed. The application includes a feature that allows users to share images directly to X (formerly Twitter) and Facebook. During testing, I encountered an issue where the icons for X (formerly Twitter) and Facebook do not appear in the share dialog, despite both apps being installed on the device. This issue prevents users from sharing images to these platforms directly from the app. Steps to Reproduce: 1.Install iOS 26 Beta on a compatible device. 2.Ensure that both the X (formerly Twitter) and Facebook apps are installed and logged in on the device. 3.Open the iOS application and navigate to the image sharing feature. 4.Attempt to share an image using the share dialog. 5.Observe that the icons for X (formerly Twitter) and Facebook are missing from the share options. Expected Behavior: The share dialog should display icons for X (formerly Twitter) and Facebook, allowing users to share images directly to these platforms. Actual Behavior: The icons for X (formerly Twitter) and Facebook do not appear in the share dialog, preventing direct sharing to these platforms. Code Implementation: I have not implemented any code to exclude X (formerly Twitter) and Facebook from the share options. Below is the relevant code for controlling the share screen: let activityViewController = UIActivityViewController(activityItems: activityItems, applicationActivities: applicationActivities) let excludedTypes = [ UIActivity.ActivityType.assignToContact, UIActivity.ActivityType.print, ] activityViewController.excludedActivityTypes = excludedTypes activityViewController.completionWithItemsHandler = completion self.present(activityViewController, animated: true, completion: nil) As shown in the implementation, there is no exclusion of X (formerly Twitter) and Facebook, yet their icons do not appear in the share dialog.

The Liquid glass blur effect does not show over the UITabBar as content scrolls underneath.
In iOS26, when using a standalone UITabBar without UITabBarController, the liquid glass blur effect is not applied when scrollable content moves behind the tab bar. However, the blur effect appears correctly when using UITabBarController. Sample Screenshots: When using UITababr When using UITababrController Sample Code: class SimpleTabBarController: UIViewController, UITabBarDelegate { let tabBar = UITabBar() let redItem = UITabBarItem(title: "Red", image: .add, tag: 0) let blueItem = UITabBarItem(title: "Blue", image: .checkmark, tag: 1) override func viewDidLoad() { super.viewDidLoad() view.backgroundColor = .white tabBar.items = [redItem, blueItem] tabBar.selectedItem = redItem tabBar.delegate = self tabBar.translatesAutoresizingMaskIntoConstraints = false let tableContainerView = TableContainerView() view.addSubview(tableContainerView) tableContainerView.translatesAutoresizingMaskIntoConstraints = false NSLayoutConstraint.activate([ tableContainerView.topAnchor.constraint(equalTo: view.topAnchor), tableContainerView.leadingAnchor.constraint(equalTo: view.leadingAnchor), tableContainerView.trailingAnchor.constraint(equalTo: view.trailingAnchor), tableContainerView.bottomAnchor.constraint(equalTo: view.bottomAnchor) ]) view.addSubview(tabBar) NSLayoutConstraint.activate([ tabBar.leadingAnchor.constraint(equalTo: view.leadingAnchor), tabBar.trailingAnchor.constraint(equalTo: view.trailingAnchor), tabBar.bottomAnchor.constraint(equalTo: view.bottomAnchor) ]) }

OTP AutoFill Fails to Distribute Code Across Multiple UITextFields on iOS 26.x
Issue Summary: On iOS 26.0.1 to 26.3, apps using multiple UITextFields for OTP input face a critical issue where the system autofill pastes the entire OTP string into a single text field, usually the focused one, rather than splitting digits across fields. Delegate events like textDidChange: do not trigger consistently on autofill, breaking existing input handling logic. Expected Behavior: OTP autofill should distribute each digit correctly across all OTP UITextFields. Delegate or control events should fire on autofill to enable manual handling. (BOOL)textField:(UITextField *)textField shouldChangeCharactersInRange:(NSRange)range replacementString:(NSString *)string { if (string.length > 1) { // Autofill detected - distribute OTP manually for (int i = 0; i < string.length && i < self.arrayOTPText.count; i++) { UITextField *field = self.arrayOTPText[i]; field.text = [NSString stringWithFormat:@"%c", [string characterAtIndex:i]]; } UITextField *lastField = self.arrayOTPText[string.length - 1]; [lastField becomeFirstResponder]; return NO; } // Handle normal single character or deletion input here return YES; } // // Setup UITextFields - set .oneTimeCode on first field only for (int i = 0; i < self.arrayOTPText.count; i++) { UITextField *field = self.arrayOTPText[i]; field.delegate = self; if (@available(iOS 12.0, *)) { field.textContentType = (i == 0) ? UITextContentTypeOneTimeCode : UITextContentTypeNone; } } What We’ve Tried: Setting textContentType properly. Handling OTP distribution in delegate method. Verifying settings and keyboard use. Testing on multiple iOS 26.x versions. Impact: Major usability degradation during OTP entry. Forces fragile workarounds. Inconsistent autofill reduces user confidence. Request: Request Apple fix OTP autofill to natively support multi-field UITextField OTP input or provide enhanced delegate callbacks for consistent behavior. Did any one face this issue in recent time with iOS 26.0.1 to 26.3 beta version

Keyboard dismissal not animated
Hello, I’ve encountered what seems to be a bug with the keyboard dismissal animation on iOS 26.0 Beta (25A5349a), Xcode Version 26.0 beta 5 (17A5295f). When dismissing the keyboard from a SwiftUI TextField using @FocusState, the keyboard does not animate downward as expected. Instead, it instantly disappears, which feels jarring and inconsistent with system behavior. I am attaching a short video demonstrating the issue. Below is the minimal reproducible code sample: // // ContentView.swift // TestingKeyboardDismissal // // Created by Sasha Morozov on 27/08/25. // import SwiftUI struct ContentView: View { @State private var text: String = "" @FocusState private var isFocused: Bool var body: some View { ZStack { Color.clear.ignoresSafeArea() VStack(spacing: 20) { TextField("Enter text here...", text: $text) .textFieldStyle(.roundedBorder) .focused($isFocused) .padding(.horizontal) HStack { Button("Focus") { isFocused = true } .buttonStyle(.borderedProminent) Button("Unfocus") { isFocused = false } .buttonStyle(.bordered) } } .frame(maxWidth: .infinity, maxHeight: .infinity, alignment: .center) .padding() } .ignoresSafeArea(.keyboard, edges: .bottom) } } #Preview { ContentView() } Steps to reproduce: Run** the app on iOS 26.0 beta 5 (17A5295f). Tap Focus → keyboard appears as expected. Tap Unfocus → keyboard disappears instantly without the usual slide-down animation. Expected result: Keyboard should animate smoothly downwards when dismissed. Actual result: Keyboard instantly vanishes without animation. p.s. we should be really able to upload videos here for demostration

tvOS 18.0 Siri back button behavior bug
On testing my app with tvOS 18, I have noticed the Siri Remote back button no longer provides system-provided behavior when interacting with tab bar controller pages. Instead of moving focus back to the tab bar when pressed, the back button will close the app, as if the Home button was pressed. This occurs both on device and in the Simulator. Create tvOS project with a tab bar controller. Create pages/tabs which contain focusable items (ie. buttons) Scroll down to any focusable item (ie. a button or UICollectionView cell) Hit the Siri Remote back button. See expect behavior below: Expected behavior: System-provided behavior should move focus back to the tab bar at the top of the screen. Actual results: App is closed and user is taken back to the Home Screen. Has anyone else noticed this behavior?

Issue with multiple touches with "Defer System Gestures" on, with iOS
I'm developing a rhythm game for iOS which has four buttons spanning the width of the screen in portrait. I noticed that my testers were having some missed inputs on the buttons on the left and right due to the fact that iOS, by default, tries to ignore accidental touches on the edges of the screen. So I enabled "Defer System Gestures" on the left and right edges, but then quickly started to notice a new, very specific, issue. Description of the issue If you have finger #1 touching and holding anywhere in the middle of the screen, and finger #2 touches on the far right or left edge of the screen just below the horizontal position of finger #1, those touches are inconsistently not recognized. If finger #1 is not present, this issue does not occur. If finger #2 is above or well below finger #1, this issue also does not occur. A dead zone is created on the right and left edges of the screen just below the horizontal position of the first touch. Here is a rough representative example of where touches #1 and #2 need to be for this issue to manifest, in case the text above is not clear. |&amp;#9;&amp;#9;&amp;#9;&amp;#9;| |&amp;#9;&amp;#9;&amp;#9;&amp;#9;| |&amp;#9;&amp;#9;&amp;#9;&amp;#9;| |&amp;#9;&amp;#9;&amp;#9;&amp;#9;| |&amp;#9; 1&amp;#9;&amp;#9;| |&amp;#9;&amp;#9;&amp;#9; 2| |&amp;#9;&amp;#9;&amp;#9;&amp;#9;| It just so happens that this issue is causing major usability problems with my game, as it results in what the user sees as sporadic and inconsistent response when the game calls for two notes to be played at the same time. Steps to recreate the issue Here are the steps if you want to recreate the problem yourself using the "Create New Gesture" pane in "Assistive Touch" (Note that this problem is not specific to the Settings app, but rather is an issue across the system—however this panel defers system gestures and shows where touches are being read, so it is a great place to demonstrate): (1) Go to Settings &gt; Accessibility &gt; Touch &gt; Assistive Touch &gt; Create New Gesture...; (2) With one finger, touch the middle of the screen and hold it through step 3; (3) With a second finger, tap 4 times along the right (or left) edge of the screen in the following places: (a) well above the vertical position of the first touch, (b) just above the vertical position of the first touch, (c) just below the vertical position of the first touch, and (d) well below the vertical position of the first touch; (4) Notice how, more than half the time, touch (c) does not register. I have found that this problem is more replicatable when the first touch is on the lower half of the screen, but I have been able to replicate it when the finger is higher as well, just not as consistently. Here are the four positions described in the steps above: Position a: both touches register |&amp;#9;&amp;#9;&amp;#9;&amp;#9;| |&amp;#9;&amp;#9;&amp;#9;&amp;#9;| |&amp;#9;&amp;#9;&amp;#9;&amp;#9;| |&amp;#9;&amp;#9;&amp;#9; 2| |&amp;#9; 1&amp;#9;&amp;#9;| |&amp;#9;&amp;#9;&amp;#9;&amp;#9;| |&amp;#9;&amp;#9;&amp;#9;&amp;#9;| Position b: both touches usually register |&amp;#9;&amp;#9;&amp;#9;&amp;#9;| |&amp;#9;&amp;#9;&amp;#9;&amp;#9;| |&amp;#9;&amp;#9;&amp;#9;&amp;#9;| |&amp;#9;&amp;#9;&amp;#9;&amp;#9;| |&amp;#9; 1&amp;#9; 2| |&amp;#9;&amp;#9;&amp;#9;&amp;#9;| |&amp;#9;&amp;#9;&amp;#9;&amp;#9;| Position c: only touch 1 registers |&amp;#9;&amp;#9;&amp;#9;&amp;#9;| |&amp;#9;&amp;#9;&amp;#9;&amp;#9;| |&amp;#9;&amp;#9;&amp;#9;&amp;#9;| |&amp;#9;&amp;#9;&amp;#9;&amp;#9;| |&amp;#9; 1&amp;#9;&amp;#9;| |&amp;#9;&amp;#9;&amp;#9; 2| |&amp;#9;&amp;#9;&amp;#9;&amp;#9;| Position d: both touches register |&amp;#9;&amp;#9;&amp;#9;&amp;#9;| |&amp;#9;&amp;#9;&amp;#9;&amp;#9;| |&amp;#9;&amp;#9;&amp;#9;&amp;#9;| |&amp;#9;&amp;#9;&amp;#9;&amp;#9;| |&amp;#9; 1&amp;#9;&amp;#9;| |&amp;#9;&amp;#9;&amp;#9;&amp;#9;| |&amp;#9;&amp;#9;&amp;#9; 2| Is there anything I can do to resolve this behavior? My app requires gesture deferment to be on for the expected experience by the user, and this bug is causing other issues for my testers that kind of need to be resolved before I can confidently release the game.

Liquid Glass clear variant isn't clear
I've been experimenting with Liquid Glass quite a bit and watched all the WWDC videos. I'm trying to create a glassy segmented picker, like the one used in Camera: however, it seems that no matter what I do there's no way to recreate a truly clear (passthrough) bubble that just warps the light underneath around the edges. Both Glass.regular and Glass.clear seem to add a blur that can not be evaded, which is counter to what clear ought to mean. Here are my results: I've used SwiftUI for my experiment but I went through the UIKit APIs and there doesn't seem to be anything that suggests full transparency. Here is my test SwiftUI code: struct GlassPicker: View { @State private var selected: Int? var body: some View { ScrollView([.horizontal], showsIndicators: false) { HStack(spacing: 0) { ForEach(0..<20) { i in Text("Row \(i)") .id(i) .padding() } } .scrollTargetLayout() } .contentMargins(.horizontal, 161) .scrollTargetBehavior(.viewAligned) .scrollPosition(id: $selected, anchor: .center) .background(.foreground.opacity(0.2)) .clipShape(.capsule) .overlay { DefaultGlassEffectShape() .fill(.clear) // Removes a semi-transparent foreground fill .frame(width: 110, height: 50) .glassEffect(.clear) } } } Is there any way to achieve the above result or does Apple not trust us devs with more granular control over these liquid glass elements?

UITabBar Appears During Swipe-Back Gesture on iOS 26 Liquid Glass UI
Hello, While integrating the Liquid Glass UI introduced in iOS 26 into my existing app, I encountered an unexpected issue. My app uses a UITabBarController, where each tab contains a UINavigationController, and the actual content resides in each UIViewController. Typically, I perform navigation using navigationController?.pushViewController(...) and hide the TabBar by setting vc.hidesBottomBarWhenPushed = true when needed. This structure worked perfectly fine prior to iOS 26, and I believe many apps use a similar approach. However, after enabling Liquid Glass UI, a problem occurs. Problem Description From AViewController, I push BViewController with hidesBottomBarWhenPushed = true. BViewController appears, and the TabBar is hidden as expected. When performing a swipe-back gesture, as soon as AViewController becomes visible, the TabBar immediately reappears (likely due to A’s viewWillAppear). The TabBar remains visible for a short moment even if the gesture is canceled — during that time, it is also interactable. Before iOS 26, the TabBar appeared synchronized with AViewController and did not prematurely show during the swipe transition. Tried using the new iOS 18 API: tabBarController?.setTabBarHidden(false, animated: true) It slightly improves the animation behavior, but the issue persists. If hidesBottomBarWhenPushed is now deprecated or discouraged, migrating entirely to setTabBarHidden would require significant refactoring, which is not practical for many existing apps. Is this caused by a misuse of hidesBottomBarWhenPushed, or could this be a regression or design change in iOS 26’s Liquid Glass UI?

UIViewRepresentable never dismantled on deletion (MEMORY LEAK)
I have find out that a UIViewRepresentable, even with a simples UIView, seems to never be dismantled when deleted from a ForEach and this can cause serious crashes. In the following example you can observe this behavior by deleting a row from the list. The dismantleUIView function of SomeUIViewRepresentable or the deinit of SomeUIView are never called. Has anyone faced this and found a solution for it? I have also filled a Feedback: FB11979117 class SomeUIView: UIView {     deinit {         print(#function)     } } struct SomeUIViewRepresentable: UIViewRepresentable {     func makeUIView(context: Context) -> SomeUIView {         let uiView = SomeUIView()         uiView.backgroundColor = .systemBlue         return uiView     }     func updateUIView(_ uiView: SomeUIView, context: Context) { }     static func dismantleUIView(_ uiView: SomeUIView, coordinator: Coordinator) {         print(#function)     } } struct Model: Identifiable {     let id = UUID() } struct ContentView: View {     @State var models = [Model(), Model(), Model(), Model(), Model()]     var body: some View {         List {             ForEach(models) { _ in                 SomeUIViewRepresentable()             }             .onDelete {                 models.remove(atOffsets: $0)             }         }     } }

Popovers are broken on Catalyst builds without portrait support
On macOS 15.2, any Mac Catalyst project that does not support portrait iPad orientation will no longer be able to successfully show the contents of any popover controls. This does not appear to be a problem on earlier versions of macOS and it only affects Mac Catalyst builds, not "Designed for iPad" builds. STEPS TO REPRODUCE Create a project that utilizes Mac Catalyst. Create a simple button that shows a popover with simple content. Remove Portrait as a supported orientation. Run the project on macOS 15.2 as a Mac Catalyst build. Note that the content inside the popover is not shown the popover is shown. Run the project as Designed for iPad. Note that the popover content shows correctly.

hidesBottomBarWhenPushed is bugged on iOS 26
I am using a common UI pattern: UITabBarController as window root, each tab with a separate UINavigationController stack. I want the (bottom!) tab bar to be only visible when the user is at the root of the app and hide it when a detail page is opened. To do that, I used hidesBottomBarWhenPushed on any view controller that would be pushed on my navigation stacks and that worked fine in the past. But with iOS 26, I am seeing several issues: On iOS where when the bottom tab bar is used, when in a details page and navigating back, the tab bar becomes fully visible immediately instead of slowly animating in as it has been in the past. This is particular visible and annoying when using the "swipe to go back" gesture On iPad, the situation is even worse: On iPadOS 18, the tab bar appeared in the navigation controller's navigation bar - no matter if hidesBottomBarWhenPushed was set or not - fine. But now, with iPadOS 26, this top tab bar disappears when a child is pushed. Not only that, it disappears abruptly, without animation, and the Liquid Glass effect on the UIBarButtonItems is broken as well. There is no transition whatsoever, buttons are simply replaced with the new UIBarButtonItems of the pushed view controller once it became fully visible. It gets even worse when swipe-back navigating on iPadOS: As soon as the back transition starts, the tab bar becomes visible again (without animation), covering the title (view) of the UINavigationController. If the swipe-back transition is not completed the tab bar suddenly stays visible When the swipe-back transition is interrupted close to the end of the transition and it goes back to the pushed view controller, the top UIBarButtonItems are showing a visual glitch where the content (text or icon) stays on the area where the tab bar is, while their container (the glass effect) are on the vertically aligned to the title view. I am surprised that I have not found any similar reports of these problems, so I am wondering if I am doing anything wrong or using hidesBottomBarWhenPushed simply isn't recommended or supported any more.

SwiftUI navigationTransition(.zoom) glitches during interactive swipe-back
Hi everyone 👋 I’m fairly new to iOS development and I’ve been stuck on a SwiftUI issue for a while now, so I’m hoping someone here can spot what I’m doing wrong. I’m using navigationTransition(.zoom) together with matchedTransitionSource to animate navigation between views. The UI consists of a grid of items (currently a LazyVGrid, though the issue seems unrelated to laziness). Tapping an item zooms it into its detail view, which is structurally the same view type and can contain further items. All good expect that interactive swipe-back sometimes causes the item to disappear from the grid once the parent view is revealed. This only happens when dismissing via the drag gesture; it does not occur when using the back button. I’ve attached a short demo showing the issue and the Swift file containing the relevant view code. Is there something obvious I’m doing wrong with navigationTransition / matchedTransitionSource, or is this a known limitation or bug with interactive swipe-back? Thanks in advance. import SwiftUI struct TestFileView: View { @Namespace private var ns: Namespace.ID let nodeName: String let children: [String] let pathPrefix: String private func transitionID(for childName: String) -> String { "Zoom-\(pathPrefix)->\(childName)" } private let columns = Array(repeating: GridItem(.flexible(), spacing: 12), count: 3) var body: some View { ScrollView { VStack(alignment: .leading, spacing: 12) { Text(nodeName) .font(.title.bold()) .padding(.bottom, 6) LazyVGrid(columns: columns, spacing: 12) { ForEach(children, id: \.self) { childName in let id = transitionID(for: childName) NavigationLink { TestFileView( nodeName: childName, children: childrenFor(childName), pathPrefix: "\(pathPrefix)/\(childName)" ) .navigationTransition(.zoom(sourceID: id, in: ns)) } label: { TestFileCard(title: childName) .matchedTransitionSource(id: id, in: ns) } .buttonStyle(.plain) } } } .padding() } } private func childrenFor(_ name: String) -> [String] { switch name { case "Lorem": return ["Ipsum", "Dolor", "Sit"] case "Ipsum": return ["Amet", "Consectetur"] case "Dolor": return ["Adipiscing", "Elit", "Sed"] case "Sit": return ["Do", "Eiusmod"] case "Amet": return ["Tempor", "Incididunt", "Labore"] case "Adipiscing": return ["Magna", "Aliqua"] case "Elit": return ["Ut", "Enim", "Minim"] case "Tempor": return ["Veniam", "Quis"] case "Magna": return ["Nostrud", "Exercitation"] default: return [] } } } struct TestFileCard: View { let title: String var body: some View { VStack(alignment: .leading, spacing: 8) { Image(systemName: "square.stack.3d.up") .symbolRenderingMode(.hierarchical) .font(.headline) Text(title) .font(.subheadline.weight(.semibold)) .lineLimit(2) .minimumScaleFactor(0.85) Spacer(minLength: 0) } .padding(12) .frame(maxWidth: .infinity, minHeight: 90, alignment: .topLeading) .background(.thinMaterial, in: RoundedRectangle(cornerRadius: 14, style: .continuous)) } } private struct TestRoot: View { var body: some View { NavigationStack { TestFileView( nodeName: "Lorem", children: ["Ipsum", "Dolor", "Sit"], pathPrefix: "Lorem" ) } } } #Preview { TestRoot() }

Increase Contrast reduces List selection contrast in dark appearance in SwiftUI NavigationSplitView
[Submitted as FB22200608] With Increase Contrast turned on, the selected row highlight in a List behaves inconsistently between light and dark appearance on iPad. In light appearance the blue selection highlight correctly becomes darker, but in dark appearance it becomes lighter instead. The text contrast ratio drops from about 3:1 to about 1.5:1, well below accessibility guidelines. This reproduces both in the simulator and on a physical device. The sample uses a standard SwiftUI List inside NavigationSplitView with built-in selection styling. No custom colors or styling are applied. REPRO STEPS Create a new Multiplatform project. Replace ContentView with code below. Build and run on iPad. Select an item in the list. Turn on Dark appearance (Cmd-Shift-A in Simulator). Turn on Increase Contrast (Cmd-Control-Shift-A in Simulator). Observe the selected row highlight. ACTUAL In light appearance, the blue selection highlight becomes darker when Increase Contrast is on, improving contrast as expected. In dark appearance, the blue selection highlight becomes lighter when Increase Contrast is on, reducing contrast between the selection background and the white text. EXPECTED Increase Contrast should consistently increase contrast. In dark appearance, the selection highlight should become darker—or otherwise increase contrast with the foreground text—not lighter. SAMPLE CODE struct ContentView: View { @State private var selection: String? var body: some View { NavigationSplitView { Text("Sidebar") } content: { List(selection: $selection) { Text("Item One") .tag("One") Text("Item Two") .tag("Two") } } detail: { if let selection { Text(selection) } else { Text("Select an item") } } } } SCREEN RECORDING CONTACTS The Contacts app behaves correctly. When Increase Contrast is turned on, the selection blue becomes darker, improving contrast. PASSWORDS The Passwords app, however, exhibits the issue. With Increase Contrast turned on, the selection blue becomes lighter instead of darker, reducing contrast.

Implicit list row animations broken in Form container on iOS 26 beta 3
[Submitted as FB18870294, but posting here for visibility.] In iOS 26 beta 3 (23A5287g), implicit animations no longer work when conditionally showing or hiding rows in a Form. Rows with Text or other views inside a Section appear and disappear abruptly, even when wrapped in withAnimation or using .animation() modifiers. This is a regression from iOS 18.5, where the row item animates in and out correctly with the same code. Repro Steps Create a new iOS App › SwiftUI project. Replace its ContentView struct with the code below Build and run on an iOS 18 device. Tap the Show Middle Row toggle and note how the Middle Row animates. Build and run on an iOS 26 beta 3 device. Tap the Show Middle Row toggle. Expected Middle Row item should smoothly animate in and out as it does on iOS 18. Actual Middle Row item appears and disappears abruptly, without any animation. Code struct ContentView: View { @State private var showingMiddleRow = false var body: some View { Form { Section { Toggle( "Show **Middle Row**", isOn: $showingMiddleRow.animation() ) if showingMiddleRow { Text("Middle Row") } Text("Last Row") } } } }

unselectedItemTintColor of tabBarItem in iOS 26
Hi, I am running iOS Simulator on iOS 26 and I am trying to change unselectedItemTintColor of UITabBarItem in my TabBarViewController but it did not work when I tried following ways: Setting an iconColor through UITabBarAppearance() class Setting unselected item tint color like tabBar.unselectedItemTintColor = .black As an example attached file, I would like to set Settings tab's item color (icon + title) with different one when it is unselected.

Large title is not visible in iOS 26
I am using below code to change navigationBar bg colour, but the text is hidden in large title. It works fine in previous versions. Kindly refer below code and attached images. Code: override func viewWillAppear(_ animated: Bool) { super.viewWillAppear(animated) navigationController?.navigationBar.prefersLargeTitles = true navigationItem.largeTitleDisplayMode = .always let appearance = UINavigationBarAppearance() appearance.backgroundColor = UIColor( red: 0.101961, green: 0.439216, blue: 0.388235, alpha: 1.0 ) navigationController?.navigationBar.standardAppearance = appearance navigationController?.navigationBar.scrollEdgeAppearance = appearance navigationController?.navigationBar.compactAppearance = appearance } Referenced images:

SwiftUI navigationTransition Regression on iOS 26 (Source View Disappears + Flicker/Misaligned Geometry)
Summary I’m experiencing two issues with SwiftUI’s navigationTransition(.zoom) on iOS 26.0 and 26.1 that break previously smooth transitions. These issues appear both on real devices and Simulator. The same code works correctly on iOS 18. Issue 1 - Source View Disappears After Drag-Dismiss When using .navigationTransition(.zoom(sourceID:..., in:...)), the source view disappears completely after the transition finishes. This only happens when the detail view is dismissed via drag (interactive dismiss). When the view is dismissed by tapping the back button, the source view remains visible as expected. Reproduced on: iOS 26.0, iOS 26.0.1 (17A400), iOS 26.1 (Simulator + physical device) Issue 2 — Flickering and Geometry Mismatch During Transition Compared to iOS 18 behavior, the outgoing view and incoming view no longer share consistent geometry. Current behavior on iOS 26: The disappearing view flickers during the drag-dismiss interaction. The source and destination views no longer align geometrically. Instead of smoothly morphing as in previous iOS versions, the two views briefly overlap incorrectly before applying the zoom animation. Expected (iOS 18) behavior: Matched geometry between source and destination. Smooth, stable zoom transition with no flickering. // // ContentView.swift // DummyTransition // // Created by Sasha Morozov on 12/11/25. // import SwiftUI struct RectItem: Identifiable, Hashable { let id: UUID = UUID() let title: String let color: Color } struct ContentView: View { @Namespace private var zoomNamespace private let items: [RectItem] = [ RectItem(title: "Red card", color: .red), RectItem(title: "Blue card", color: .blue), RectItem(title: "Green card", color: .green), RectItem(title: "Orange card", color: .orange) ] var body: some View { NavigationStack { ScrollView { VStack(spacing: 16) { ForEach(items) { item in NavigationLink { DetailView(item: item, namespace: zoomNamespace) .navigationTransition( .zoom(sourceID: item.id, in: zoomNamespace) ) } label: { RoundedRectangle(cornerRadius: 16) .fill(item.color.gradient) .frame(height: 120) .overlay( Text(item.title) .font(.headline) .foregroundStyle(.white) ) .padding(.horizontal, 16) .matchedTransitionSource(id: item.id, in: zoomNamespace) } .buttonStyle(.plain) } } .padding(.vertical, 20) } .navigationTitle("Cards") } } } struct DetailView: View { let item: RectItem let namespace: Namespace.ID var body: some View { ZStack { item.color Text(item.title) .font(.largeTitle.bold()) .foregroundStyle(.white) } .ignoresSafeArea() .navigationTitle("Detail") .navigationBarTitleDisplayMode(.inline) } } #Preview { ContentView() } Testing Environment MacBook Pro (2023, M2 Pro, 16 GB RAM) macOS 26.2 Beta (25C5031i) Xcode: Version 26.0.1 (17A400) Devices tested: Simulator (iOS 26.0 / 26.1) Physical device (iPhone 16) running iOS 26.1
