Hello Apple Team,
I’ve encountered a regression in iOS 26.1 when building my app with Xcode 26 (iOS 26 SDK).
The issue affects PKPaymentButtonType.plain, which now renders as fully invisible and produces transparent snapshots, even though the same code worked correctly in previous Xcode/iOS versions.
This has a real-world impact because many apps generate static images from PKPaymentButton for payment selection UIs using UIGraphicsImageRenderer, layer.render(in:), or custom snapshot utilities.
When using
PKPaymentButton(paymentButtonType: .plain, paymentButtonStyle: .black)
on iOS 26.1, when built with Xcode 26, the button:
Appears blank / invisible
Cannot be snapshotted
Produces a fully transparent UIImage, even though the CGImage object exists
Behaves differently than older SDKs (Xcode 16.x / iOS < 26.1
This regression only appears when compiling with the new SDK.
Other button types work fine.
Expected Behavior
.plain button should render glyphs as documented
snapshot generated via UIGraphicsImageRenderer or drawHierarchy(in:) should produce a visible image
Behavior should be consistent with older SDKs unless explicitly deprecated in release notes
Expected Behavior
.plain button should render glyphs as documented
Snapshot generated via UIGraphicsImageRenderer or drawHierarchy(in:) should produce a visible image
Behavior should be consistent with older SDKs unless explicitly deprecated in release notes
Actual Behavior
.plain button renders no glyph at all
Snapshot image is fully transparent (alpha = 0), even though size and CGImage metadata are correct
Only happens when built with Xcode 26 SDK
Same build from Xcode 16.x does not reproduce the issue
Steps to Reproduce
Create a minimal sample project in Xcode 26
Add the following code:
let button = PKPaymentButton(paymentButtonType: .plain, paymentButtonStyle: .black)
button.frame = CGRect(x: 0, y: 0, width: 180, height: 48)
let renderer = UIGraphicsImageRenderer(size: button.bounds.size)
let image = renderer.image { _ in
button.drawHierarchy(in: button.bounds, afterScreenUpdates: true)
}
print(image)
Run on iOS 26.1 device or simulator
Observe that:
The button appears visually empty
The generated image is fully transparent
Environment
Xcode: 26.x (iOS 26 SDK)
iOS: 26.1 (iPhone 15 Pro tested)
Device: Real device
Framework: UIKit + PassKit
Button type: .plain ONLY
Other types: .pay/.buy/.checkout = OK

Apparently now with iOS 26.1 if you have .tabViewBottomAccessory { } you get a pill shape floater all the time. That was not like that in 26.0.
How do we disable the new swipe left anywhere to navigate back? I already use that swipe motion for custom actions in my app.

After updating to Xcode 26 my XCUITests are now failing as during execution exceptions are being raised and caught by my catch all breakpoint
These exceptions are only raised during testing, and seem to be referencing some private internal property. It happens when trying to tap a button based off an accessibilityIdentifier
e.g.
accessibilityIdentifier = "tertiary-button"
...
...
app.buttons["tertiary-button"].tap()
The full error is:
Thread 1: "[<UIKit.ButtonBarButtonVisualProvider 0x600003b4aa00> valueForUndefinedKey:]: this class is not key value coding-compliant for the key _titleButton."
Anyone found any workarounds or solutions? I need to get my tests running on the liquid glass UI
I am using AlarmKit to schedule alarms in an app I am working on, however my scheduled alarms only show up on the lock screen. If I am on the home screen or elsewhere I only hear the sound of the alarm, but no UI shows up.

We are building a CarPlay app and have run into an issue with data updates.
When the app is running on the CarPlay display and the iPhone screen is locked, no data updates are shown on the CarPlay screen. As soon as the phone is unlocked, the data updates appear instantly on the CarPlay display.
Has anyone encountered this behavior before? Is there a specific setting, entitlement, or background mode we need to enable in order to ensure the CarPlay app continues to receive and display data while the iPhone is locked?
Any guidance would be greatly appreciated.
I understand this is a known issue, but it’s truly unacceptable that it remains unresolved. Allowing users to customize toolbars is a fundamental macOS feature, and it has been broken since the release of macOS 15.
How is it possible that this issue persists even in macOS 15.3 beta (24D5040f)?

Hi there,
Upon using List View for tabular information showcase on both iOS and iPadOS, I have come to realize that the drag and drop support works only for iPadOS but not iOS.
Although it is possible to workaround this by using a ScrollView wrapping around a LazyVStack instead, the editing mode along with left-wipe to delete feature would be missing. Not to mention that this workaround only supports single item rather than multiple items.
Therefore, I am here to ask if the drag and drop will come to support devices running iOS, and if so, when will this feature ship. If not, will LazyVStack/LazyHStack support native editing mode.
Thank you for your time.
Hello.
Is there a good SwiftUI approach on getting the TextEditor cursor position?
I have a TextEditor and sometimes when we have a longer text inside it, the cursor is not seen because the keyboard is above covering the bottom of the TextEditor.
I would like to somehow detect the position of the cursor, and if it's on the last line of the TextEditor, scroll to the bottom. I've already checked a bit and didn't find any good method of doing this in SwiftUI.
If you have any ideas on how to do this, or even a different method any help would be highly appreciated.
Thank you!
I want to add a widget to my app that will display the # of pickups the user has for the day. I have the DeviceActivityReport working in the main app but can't get it to display in the widget since it is not a supported view for widgets. Is there any workaround for getting this view to the widget?
I tried converting the DeviceActivityReport view to a UI image thinking maybe that would be a way to use a widget approved view type but ImageRenderer seems to fail to render an image for the view (which is just a Text view).
To summarize my questions:
Is it possible to display a DeviceActivityReport in a widget? If so, what is the best practice?
Is converting the DeviceActivityReport view into an image and displaying that in a widget an option?
Here's my attempt to convert the DeviceActivityReport view into a UIImage:
import SwiftUI
import _DeviceActivity_SwiftUI
struct PickupsDeviceActivityReport: View {
@State private var context: DeviceActivityReport.Context = .totalActivity
@State private var renderedImage = Image(systemName: "exclamationmark.triangle")
@Environment(\.displayScale) var displayScale
var body: some View {
renderedImage
.onAppear { render() }
.onChange(of: context) {
_ in render()
}
}
@MainActor func render() {
let renderer = ImageRenderer(content: DeviceActivityReport(context))
renderer.scale = displayScale
if let uiImage = renderer.uiImage {
renderedImage = Image(uiImage: uiImage)
}
}
}
Help is appreciated. Thank you.
I have a couple of (older) UIKit-based Apps using UISplitViewController on the iPad to have a two-column layout. I'm trying to edit the App so it will shows the left column as sidebar with liquid glass effect, similar to the one in the "Settings" App of iPadOS 26. But this seems to be almost impossible to do right now.
"out of the box" the UISplitViewController already shows the left column somehow like a sidebar, with some margins to the sides, but missing the glass effect and with very little contrast to the background. If the left column contains a UITableViewController, I can try to get the glass effect this way within the UITableViewController:
tableView.backgroundColor = .clear
tableView.backgroundView = UIVisualEffectView(effect: UIGlassContainerEffect())
It is necessary to set the backgroundColor of the table view to the clear color because otherwise the default background color would completely cover the glass effect and so it's no longer visible.
It is also necessary to set the background of all UITableViewCells to clear.
If the window is in the foreground, this will now look very similar to the sidebar of the Settings App.
However if the window is in the back, the sidebar is now much darker than the one of the Settings App. Not that nice looking, but for now acceptable.
However whenever I navigate to another view controller in the side bar, all the clear backgrounds destroy the great look, because the transition to the new child controller overlaps with the old parent controller and you see both at the same time (because of the clear backgrounds).
What is the best way to solve these issues and get a sidebar looking like the one of the Settings App under all conditions?
It happens on a brand new SwiftUI Xcode project with nothing in it but the default base code. When I build and run, I get "Error creating the CFMessagePort needed to communicate with PPT." After some Googling, I know it has something to do with Performance Tools. I don't know what's causing it.
I'm running 16.2 on a brand new M4 Mac mini.

In iOS 26.1, SwiftUI's tabViewBottomAccessory API cannot control visibility properly. The tabViewBottomAccessory remains always visible, which is inconsistent with the behavior in iOS 26.0 / iOS 26.0.1.
`
struct ContentView: View {
enum Tabs {
case first
}
@State private var selection: Tabs = .first
@State private var showBottomAccessory: Bool = true
var body: some View {
tabView
}
var tabView: some View {
TabView(selection: $selection) {
Tab(value: .first) {
content
} label: {
VStack {
Text("first")
}
}
}
.tabViewBottomAccessory {
if showBottomAccessory {
Text("BottomAccessory")
}
}
}
var content: some View {
Button("change") {
showBottomAccessory.toggle()
}
}
}

I’m not seeing Liquid Glass on any standard components. A month ago around July 17th I ran our app and saw Liquid Glass on our tab view and various standard components. Those components have not been changed and yet I’m no longer seeing Liquid Glass in our app at all.
Components that were previously liquid glass but now are not include TabView and back navigation buttons.
I set the UIDesignRequiresCompatibility key explicitly to false but no luck. I was seeing this in Beta 7 and Beta 8 on a real device and on a sim.

The .disabled() modifier doesn't visually disable buttons inside a ToolbarItem container on iOS 26.0 (23A5297i) devices. The button looks enabled, but tapping it doesn't trigger the action.
When deployment target is lowered to iOS 18 and deployed to an iOS 18 device, it works correctly. It still fails on an iOS 26 device, even with an iOS 18-targeted build.
This occurs in both the Simulator and on a physical device.
Screen Recording
Code
struct ContentView: View {
@State private var isButtonDisabled = false
private var osTitle: String {
let version = ProcessInfo.processInfo.operatingSystemVersion
return "iOS \(version.majorVersion)"
}
var body: some View {
NavigationStack {
VStack {
Button("Body Button") {
print("Body button tapped")
}
.buttonStyle(.borderedProminent)
.disabled(isButtonDisabled)
Toggle("Disable buttons", isOn: $isButtonDisabled)
Spacer()
}
.padding()
.navigationTitle("Device: \(osTitle)")
.navigationBarTitleDisplayMode(.large)
.toolbar {
ToolbarItem {
Button("Toolbar") {
print("Toolbar button tapped")
}
.buttonStyle(.borderedProminent)
.disabled(isButtonDisabled)
}
}
}
}

I have a custom document-based iOS app that also runs on macOS. After implementing -activityItemsConfiguration to enable sharing from the context menu, I found that the app crashes on macOS when selecting Share… from the context menu and then selecting Save (i.e. Save to Files under iOS). This problem does not occur on iOS, which behaves correctly.
- (id<UIActivityItemsConfigurationReading>)activityItemsConfiguration {
NSItemProvider * provider = [[NSItemProvider alloc] initWithContentsOfURL:self.document.presentedItemURL];
UIActivityItemsConfiguration * configuration = [UIActivityItemsConfiguration activityItemsConfigurationWithItemProviders:@[ provider ]];
// XXX crashes with com.apple.share.System.SaveToFiles
return configuration;
}
Additionally, I found that to even reach this crash, the workaround implemented in the NSItemProvider (FBxxx) category of the sample project is needed. Without this, the app will crash much earlier, due to SHKItemIsPDF() erroneously invoking -pathExtension on an NSItemProvider. This appears to be a second bug in Apple’s private ShareKit framework.
#import <UniformTypeIdentifiers/UniformTypeIdentifiers.h>
@implementation NSItemProvider (FBxxx)
// XXX SHKItemIsPDF() invokes -pathExtension on an NSItemProvider (when running under macOS, anyway) -> crash
- (NSString *)pathExtension {
return self.registeredContentTypes.firstObject.preferredFilenameExtension;
}
@end
Again, this all works fine on iOS (17.5) but crashes when the exact same app build is running on macOS (14.5).
I believe these bugs are Apple's. Any idea how to avoid the crash? Is there a way to disable the "Save to Files" option in the sharing popup?
I filed FB13819800 with a sample project that demonstrates the crash on macOS. I was going to file a TSI to get this resolved, but I see that DTS is not responding to tech support incidents until after WWDC.

I am using the TabView control in SwiftUI on a tvOS 18 target with the style of sidebarAdaptable. When I have 7 or less tabs things operate correctly. When I add an 8th tab and you navigate to the contents of the tab the menu collapses as expected but you cannot navigate back to restore the menu. This code reproduces the issue:
import SwiftUI
struct ContentView: View {
var body: some View {
TabView {
Tab("Tab1", systemImage: "person.circle") {
Button("Button1") {}
}
Tab("Tab2", systemImage: "person.circle") {
Button("Button2") {}
}
Tab("Tab3", systemImage: "person.circle") {
Button("Button3") {}
}
Tab("Tab4", systemImage: "person.circle") {
Button("Button4") {}
}
Tab("Tab5", systemImage: "person.circle") {
Button("Button5") {}
}
Tab("Tab6", systemImage: "person.circle") {
Button("Button6") {}
}
Tab("Tab7", systemImage: "person.circle") {
Button("Button7") {}
}
Tab("Tab8", systemImage: "person.circle") {
Button("Button8") {}
}
}
.tabViewStyle(.sidebarAdaptable)
}
}
If you eliminate Tab 8 the problem goes away. You can navigate back to the menu by moving to the left.
Notably the Destination Video sample also reproduces this issue:
https://developer.apple.com/documentation/visionos/destination-video
To reproduce:
Load the above code or Destination Video sample.
Navigate right (click right on remote or swipe right). Menu dismisses and just shows the item you have selected in the upper left corner.
Try to navigate left by clicking left on the remote or swiping left. It looks like the collapsed menu gets focus briefly, screen elements flash but the focus remains outside the menu.
Has anyone else encountered this issue?
I have an NSSplitViewController with three columns:
sidebar
full-height content view with NSScrollView/NSTableView
detail view.
There's no (visible) titlebar and no toolbar.
This layout has worked fine for years, but in Tahoe an unwanted overlay (~30-50px high) appears at the top of any column containing a scroll view with table content. Xcode suggests it's an NSScrollPocket.
My research suggests it...
Only affects columns with NSScrollView
Plain NSView columns are unaffected
Overlay height varies (~50px or ~30px depending on how I mess with title / toolbar settings)
Disabling titlebar/toolbar settings reduces but doesn't eliminate the overlay
The overlay obscures content and there doesn't appear to be any API
to control its visibility. Is this intended behavior, and if so, is
there a way to disable it for applications that don't need this UI
element?
If it helps visualise the desired result, the app is https://indigostack.app
Any guidance would be appreciated!

When I add a TextField with @FocusState to a toolbar, I noticed that setting focus = false doesn't cause the form to lose focus
If I move the TextField out of the toolbar setting focus = false works fine. How can I unfocus the text field when the cancel button is tapped?
Minimal example tested on Xcode Version 26.0 beta 6 (17A5305f):
import SwiftUI
struct ContentView: View {
@State private var text: String = ""
@FocusState private var focus: Bool
var body: some View {
NavigationStack {
List {
Text("Test List")
}
.toolbar {
ToolbarItem(placement: .bottomBar) {
TextField("Test", text: $text)
.padding(.horizontal)
.focused($focus)
}
ToolbarItem(placement: .bottomBar) {
Button(role: .cancel) {
focus = false // THIS DOESN'T WORK!
}
}
}
}
}
}
#Preview {
ContentView()
}```
When disabling the opacity slider of color panels, my app crashes with unsatisfiable layout constraints. Feel free reproduce with a minimal test project: A macOS app based on the Xcode 26.0 template with only one line added to the ViewController's viewDidLoad() function:
NSColorPanel.shared.showsAlpha = false
The issue doesn't occur if this property is set to "true" or not set at all.
I just filed a corresponding bug report (FB20269686), although I don't expect any feedback from Apple ... as numerous issues I reported were never updated or commented at all (after migrating from RADARs).
