I have written a calculator app. Its main window is a UIView subclass that usually receives user input from the touchscreen, tapping on a virtual keyboard (not the standard pop-up keyboard). I recently added hardware keyboard support. In order to receive key events, I implemented canBecomeFirstResponder and made it always return YES, and I'm calling becomeFirstResponder whenever the main window becomes active, and resignFirstResponder when it becomes inactive. This is working fine except for one scenario: when running the app on an iPad, together with another app, using Split View or Slide Over, and the other app has keyboard focus on a text field, my app doesn't receive keyboard events, even when it's the foreground app. I have to go into the other app, and tap somewhere outside a text field, and then return to my app, before my app is getting key events again. If the user taps on an actual text field in my app, it gets focus just fine, of course, but apparently my UIView calling becomeFirstResponder is not enough to take away the focus from the other app. Is there a way to steal the focus from another app's text field in this scenario?

I’m having a weird UIKit problem. I have a bunch of views in a UIScrollView and I add a UIContextMenuInteraction to all of them when the view is first loaded. Because they're in a scroll view, only some of the views are initially visible. The interaction works great for any of the views that are initially on-screen, but if I scroll to reveal new subviews, the context menu interaction has no effect for those. I used Xcode's View Debugger to confirm that my interaction is still saved in the view's interactions property, even for views that were initially off-screen and were then scrolled in. What could be happening here?

hi does any one know if there changes in lifecycle in xcode 16 ios 18 cause i notice that my view will appear does what view didappear use to do in older version and it kind of a problem cause all the rest of ios work diffrently does anyone else found a problem with it? or does anyone know if there was a known change to life cycles

App update in which there were no changes regarding the widget. Just after it updated, the widget turns black in some cases. It also appears black in the widget gallery.

With iPadOS 18, the UITabBar now defaults to the floating style. I successfully reverted the tab bar to its traditional style by overriding the UITabBarController's horizontalSizeClass property: self.tabBarController?.traitOverrides.horizontalSizeClass = .unspecified When I launch the app on my Mac using Apple Silicon, TWO tab bars appear: One appears at the bottom of the screen, like a traditional tab bar. The second tab bar is still embedded in the app toolbar in its floating style. Is this a bug? How do you ensure that overriding the horizontalSizeClass will remove/hide the floating tab bar when running an app on Apple Silicon? TIA! (Demonstrated on a test project)

How do I draw a single line of text in a SwiftUI Canvas, scaled to fill a given rectangle? Example: Canvas { context, size in let r = CGRect(origin: CGPointZero, size: size); // Whole canvas let t = Text("Hello World"); context.draw(t, in: r); } Outside of Canvas I'd add .minimumScaleFactor(0) .lineLimit(1), and I guess set a large default font size, and I'd get the result I want. But inside Canvas, .minimumScaleFactor and .lineLimit don't seem to be available; they return some View, not Text, which can't be used in context.draw. (Is there a trick to make that work?) I have written the following to do this, but I think there must be an easier way to achieve this! Suggestions? extension GraphicsContext { mutating func draw_text_in_rect(string: String, rect: CGRect) { let text = Text(string) .font(.system(size: 25)); // The font size used here does matter, because e.g. letter spacing // varies with the font size. let resolved = resolve(text); let text_size = resolved.measure(in: CGSize(width: CGFloat.infinity, height: CGFloat.infinity)); let text_aspect = text_size.width / text_size.height; let fit_size = CGSize(width: min(rect.size.width, rect.size.height*text_aspect), height: min(rect.size.height, rect.size.width/text_aspect)); let fit_rect = CGRect(x: rect.origin.x + (rect.size.width-fit_size.width)/2, y: rect.origin.y + (rect.size.height-fit_size.height)/2, width: fit_size.width, height: fit_size.height); let scale = fit_size.width / text_size.width; // For debug: // var p = Path(); // p.addRect(fit_rect); // stroke(p, with: GraphicsContext.Shading.color(.red), lineWidth: 1); translateBy(x: fit_rect.minX, y: fit_rect.minY); scaleBy(x:scale, y:scale); draw(resolved, at: CGPointZero, anchor: UnitPoint.topLeading); transform = CGAffineTransformIdentity; } };

There appears to be a visual bug when using .searchable in a child view that’s pushed via NavigationLink inside a NavigationStack. Specifically, the search bar appears briefly in the wrong position (or animates in an unexpected way) during the transition to the child view. This issue does not occur when using NavigationView instead of NavigationStack. Steps to Reproduce: Create a TabView with a single tab containing a NavigationStack. Push from a ContentView to a DetailsView using NavigationLink. Add a .searchable modifier to both the ContentView and DetailsView. Run the app and tap a row to navigate to the details view. Expected Behavior The search bar in the DetailsView should appear smoothly and in the correct position as the view transitions in, just like it does under NavigationView. Actual Behavior When the DetailsView appears, the search bar briefly animates or appears in the wrong location before settling into place. This results in a jarring or buggy visual experience. Feedback: FB17031212 Here is a reddit thread discussing the issue as well https://www.reddit.com/r/SwiftUI/comments/137epji/navigation_stack_with_search_bar_has_a_bug_and_a/ I hope that an Apple engineer can get this fixed soon. It's frustrating to have new APIs come out with the old deprecated yet there are still obvious bugs two years later. import SwiftUI public enum Tab { case main } struct AppTabNavigation: View { @State private var tabSelection = Tab.main var body: some View { TabView(selection: $tabSelection) { NavigationStack { ContentView() } .tag(Tab.main) .tabItem { Label("Main", systemImage: "star") } } } } struct ContentView: View { @State private var searchText = "" var body: some View { List(0..<100) { i in NavigationLink("Select \(i)", value: i) } .navigationTitle("Main") .searchable(text: $searchText) .navigationDestination(for: Int.self) { i in DetailsView(i: i) } } } struct DetailsView: View { @State private var searchText = "" let i: Int // MARK: - Body var body: some View { List { ForEach(0..<10, id: \.self) { i in Text("Hello \(i)") } } .navigationTitle(i.formatted()) .searchable(text: $searchText) } }

I want to truncate text from head with max 2 lines. I try the following code import SwiftUI struct ContentView: View { @State var content: String = "Hello world! wef wefwwfe wfewe weweffwefwwfwe wfwe" var body: some View { VStack { Text(content) .lineLimit(nil) .truncationMode(.head) .frame(height: 50) Button { content += content } label: { Text("Double") } .buttonStyle(.borderedProminent) } .frame(width: 200, height: 1000) .padding() } } #Preview { ContentView() } It show result like this, this is not what I want.

Hey, Anyone knows of a possible way to present a PasteButton in a .confirmationDialog on iOS? when I try adding it, it's ignored and not displayed with the rest of the buttons struct MyView: View { @State var flag: Bool = false var body: some View { Text("Some Text") .confirmationDialog("Dialog", isPresented: $flag) { Group { Button("A") {} Button("B") {} PasteButton(payloadType: Data.self) { data in } } } } }

Hello, I’m developing an app where I display a SwiftUI view inside a UIHostingController embedded within a UIKit ViewController. I’m trying to animate the height of the UIHostingController’s view based on a switch’s value, but the SwiftUI view doesn’t animate at all. Below is a simplified version of my code: class ViewController: UIViewController { private lazy var parentView: UIView = { let view = UIView() view.backgroundColor = .red view.translatesAutoresizingMaskIntoConstraints = false return view }() private lazy var hostingView: UIView = { let testView = TestView() let hostingController = UIHostingController(rootView: testView) let view = hostingController.view! view.translatesAutoresizingMaskIntoConstraints = false return view }() private lazy var button: UISwitch = { let button = UISwitch() button.addTarget(self, action: #selector(onClickSwitch(sender:)), for: .valueChanged) button.translatesAutoresizingMaskIntoConstraints = false return button }() private var hostingViewHeightConstraint: NSLayoutConstraint? override func viewDidLoad() { super.viewDidLoad() view.addSubview(parentView) parentView.addSubview(hostingView) parentView.addSubview(button) NSLayoutConstraint.activate([ parentView.topAnchor.constraint(equalTo: view.topAnchor), parentView.bottomAnchor.constraint(equalTo: view.bottomAnchor), parentView.leadingAnchor.constraint(equalTo: view.leadingAnchor), parentView.trailingAnchor.constraint(equalTo: view.trailingAnchor) ]) NSLayoutConstraint.activate([ hostingView.bottomAnchor.constraint(equalTo: parentView.bottomAnchor), hostingView.leadingAnchor.constraint(equalTo: parentView.leadingAnchor), hostingView.trailingAnchor.constraint(equalTo: parentView.trailingAnchor) ]) hostingViewHeightConstraint = hostingView.heightAnchor.constraint(equalTo: parentView.heightAnchor, multiplier: 0.5) hostingViewHeightConstraint?.isActive = true NSLayoutConstraint.activate([ button.centerXAnchor.constraint(equalTo: parentView.centerXAnchor), NSLayoutConstraint(item: button, attribute: .centerY, relatedBy: .equal, toItem: parentView, attribute: .centerY, multiplier: 0.25, constant: 0) ]) } @objc func onClickSwitch(sender: UISwitch) { hostingViewHeightConstraint?.isActive = false let multiplier: CGFloat = sender.isOn ? 0.25 : 0.5 hostingViewHeightConstraint = hostingView.heightAnchor.constraint(equalTo: parentView.heightAnchor, multiplier: multiplier) hostingViewHeightConstraint?.isActive = true UIView.animate(withDuration: 0.3) { self.view.layoutIfNeeded() } } } I’m looking for the behavior demonstrated in the video below: Does anyone have suggestions on how to achieve this?

I have the MainView as the active view if the user is logged in(authenticated). the memory allocations when we run profile is pretty good. We have graphql fetching, we have token handling eg: This is All heap: 1 All Heap & Anonymous VM 13,90 MiB 65408 308557 99,10 MiB 373965 Ratio: %0.14, %0.86 After what i have checked this is pretty good for initialise and using multiple repositories eg. But when we change tabs: 1 All Heap & Anonymous VM 24,60 MiB 124651 543832 156,17 MiB 668483 Ratio: %0.07, %0.40 And that is not pretty good. So i guess we need to "kill" it or something. How? I have tried some techniques in a forum this was a recommended way: public struct LazyView<Content: View>: View { private let build: () -> Content @State private var isVisible = false public init(_ build: @escaping () -> Content) { self.build = build } public var body: some View { build() Group { if isVisible { build() } else { Color.clear } } .onAppear { isVisible = true } .onDisappear { isVisible = false } } } But this did not help at all. So under here is the one i use now. So pleace guide me for making this work. import DIKit import CoreKit import PresentationKit import DomainKit public struct MainView: View { @Injected((any MainViewModelProtocol).self) private var viewModel private var selectedTabBinding: Binding<MainTab> { Binding( get: { viewModel.selectedTab }, set: { viewModel.selectTab($0) } ) } public init() { // No additional setup needed } public var body: some View { NavigationStack(path: Binding( get: { viewModel.navigationPath }, set: { _ in } )) { TabView(selection: selectedTabBinding) { LazyView { FeedTabView() } .tabItem { Label("Feed", systemImage: "house") } .tag(MainTab.feed) LazyView { ChatTabView() } .tabItem { Label("Chat", systemImage: "message") } .tag(MainTab.chat) LazyView { JobsTabView() } .tabItem { Label("Jobs", systemImage: "briefcase") } .tag(MainTab.jobs) LazyView { ProfileTabView() } .tabItem { Label("Profile", systemImage: "person") } .tag(MainTab.profile) } .accentColor(.primary) .navigationDestination(for: MainNavigationDestination.self) { destination in switch destination { case .profile(let userId): Text("Profile for \(userId)") case .settings: Text("Settings") case .jobDetails(let id): Text("Job details for \(id)") case .chatThread(let id): Text("Chat thread \(id)") } } } } } import SwiftUI public struct LazyView<Content: View>: View { private let build: () -> Content public init(_ build: @escaping () -> Content) { self.build = build } public var body: some View { build() } }

Hi, Is there any way of changing the contentInset (UIKit variant) of a List in SwiftUI? I do not see any APIs for doing so, the closest I gotten is to use safeAreaInset . While visually that works the UX is broken as you can no longer "scroll" from the gap made by the .safeAreaInset(edge:alignment:spacing:content:) I have subbmited a feedback suggestion: FB16866956

I am working on the EndPoint DLP solution project. So I want to monitor the paste operation peformed by the user. So when he uses the keyboard keys then I can monitor them using the event callback. But if user uses the GUI for pasting the data then how can I monitor that ?

I have a UITextField in my application, and I want to detect all the keys uniquely to perform all relevant task. However, there is some problem in cleanly identifying some of the keys. I m not able to identify the backspace key press in the textField(_:shouldChangeCharactersIn:replacementString:) method. Also I don't know how to detect the Caps Lock key. I am intending to so this because I want to perform some custom handling for some keys. Can someone help me with what is the way of detecting it under the recommendation from apple. Thanks in advance. Note: checking for replacementString parameter in shouldChangeCharactersIn method for empty does not help for backspace detection as it overlaps with other cases.

When I present a view controller, whose view is a SwiftUI View, via presentAsModalWindow(_:) the presented window is no longer centered horizontally to the screen, but rather its origin is there. I know this issue occurs for macOS 15.2+, but can't tell if it is from 15.0+. I couldn't find any documentation on why was this changed. Here's an example code that represents my architecture: class RootViewController: NSViewController { private lazy var button: NSButton = NSButton( title: "Present", target: self, action: #selector(presentView)) override func viewDidLoad() { super.viewDidLoad() // Add button to tree } @objc func presentView() { presentAsModalWindow(PresentedViewController()) } } class PresentedViewController: NSViewController { override loadView() { view = NSHostingView(rootView: MyView()) } } struct MyView: View { /* impl */ }

I have received permission from Apple to access SensorKit data for my app. I have granted all necessary permissions, but no data is being retrieved. The didCompleteFetch method is being called, but I’m unsure where to find event data like Device Usage and Ambient Light. Additionally, the didFetchResult method is never called. Could anyone please assist me in resolving this issue? Any guidance or troubleshooting steps would be greatly appreciated. import SensorKit class ViewController: UIViewController, SRSensorReaderDelegate { let store = SRSensorReader(sensor: .deviceUsageReport) override func viewDidLoad() { super.viewDidLoad() requestSensorAuthorization() } func requestSensorAuthorization() { var sensors: Set<SRSensor> = [ .accelerometer, .deviceUsageReport, .messagesUsageReport, .visits, .keyboardMetrics, .phoneUsageReport, .ambientLightSensor ] if #available(iOS 16.4, *) { sensors.insert(.mediaEvents) } SRSensorReader.requestAuthorization(sensors: sensors) { error in if let error = error { print("Authorization failed: \(error.localizedDescription)") } else { self.store.startRecording() self.requestSensorData() print("Authorization granted for requested sensors.") } } } func requestSensorData() { let fromTime = SRAbsoluteTime.fromCFAbsoluteTime(_cf: Date().addingTimeInterval(-60 * 60).timeIntervalSinceReferenceDate) let toTime = SRAbsoluteTime.fromCFAbsoluteTime(_cf: Date().timeIntervalSinceReferenceDate) let request = SRFetchRequest() request.from = fromTime request.to = toTime request.device = SRDevice.current store.fetch(request) store.delegate = self } func sensorReader(_ reader: SRSensorReader, didCompleteFetch fetchRequest: SRFetchRequest) { print("Fetch request completed: \(fetchRequest.from) to \(fetchRequest.to)") Task { do { let samples = try await reader.fetch(fetchRequest) print("Samples count: \(samples)") } catch { print("Error Fetching Data: \(error.localizedDescription)") } } } func sensorReader(_ reader: SRSensorReader, fetching fetchRequest: SRFetchRequest, didFetchResult result: SRFetchResult<AnyObject>) -> Bool { print(result) return true } }

I am creating an application that uses VNDetectBarcodesRequest to read QR codes from images and adjust the image orientation to match that of the QR code finder pattern. The QR code was successfully read, and the coordinates of the QR code were obtained.Upon checking the obtained topLeft, topRight, and bottomLeft coordinates, they always seem to match the topLeft, topRight, and bottomLeft coordinates of the finder pattern. Is it specified that the coordinates of topLeft, topRight, and bottomLeft obtained with VNDetectBarcodesRequest match the topLeft, topRight, and bottomLeft of the finder pattern? Or do they just happen to match? I would appreciate it if you could tell me if the matching of coordinates is a specification. Thank you for your help.

Hi, I’m practicing with NavigationSplitView for macOS and customizing the sidebar. I’ve managed to adjust most parts, but I couldn’t remove the sidebar’s divider. It seems like it’s not possible in modern SwiftUI. My AppKit knowledge is also not very strong. How can I remove the sidebar divider? I want to use a plain background. I also solved it by creating my own sidebar, but I wanted to try it using NavigationSplitView.
