The Problem I am trying to implement a pinch-to-zoom feature on images within a UIPageViewController. However, often times when trying to pinch to zoom, the magnification gesture gets overridden by the scrolling gesture built into the UIPageViewController. I'm not sure how to get around this. The Apple Photos app seems to allow pinch to zoom on photos inside a full-page scrolling view without any issue, so I believe it should be possible. Versions: iOS 17.2.1 - iOS 18.2.1, Swift (SwiftUI), Xcode 15.1 Steps to Reproduce Run this sample Xcode project on a physical device: https://drive.google.com/file/d/1tB1QyY6QPEp-WLzdHxgDdkM45xCAELLr/view?usp=share_link Try pinching to zoom on the image. After a few goes at it, you'll likely find that one time it will scroll instead of pinching to zoom. It might take up to a dozen pinches to experience this issue. What I've Tried Making the magnification gesture a high priority gesture. Having only one page in the paging view controller. Subclassing UIScrollView and conforming to the UIGestureRecognizerDelegate in that subclass, as explained here: https://stackoverflow.com/a/51070947/12218938 Using the iOS 17 ScrollView instead. Unfortunately it has the same issue but even worse! It's possible that since this is a native SwiftUI view, people might have solutions to this, but from a brief search I couldn't find any. If you set the data source to nil (which indicates that there are no other pages for the paging view controller to scroll to), it does work, but it's not a workable solution since the time you'd want to set the data source to nil is when the user pinches the screen, but you can't know when the user pinches the screen if the gesture doesn't work! Other Ideas/Workarounds We could have some "zoom" mode that temporarily cancels the ability to scroll while zooming. But this seems like not too nice/intuitive of a solution. If there is no paging view that Apple provides which could be made compatible with a pinch-to-zoom gesture, it's possible we would have to make a completely custom paging view. But that would be a lot of work I presume, so it's probably not something we would have time for right now.

Hello. I use NavigationStack for navigating in app. I have 4 screens - A, B, C, D. In some moment I have path [A, B, C] for NavigationStack. After user did action I should show path [A, B, D]. In other hands I should replace screen C with screen D. struct HomeView: View { @ObservedObject var viewModel: HomeViewModel var body: some View { NavigationStack(path: $viewModel.path) { ContentView() .navigationDestination(for: HomeViewModel.Path.self) { destination in // B, C, D views here... } } .navigationViewStyle(StackNavigationViewStyle()) } } Solution looks like same as for UIKit. I replaced last item in stack. It works, but "push" animation broke. var updatedPath = self.path updatedPath.removeLast() updatedPath.append(newPathItem) self.path = updatedPath I found suggest in Internet that you can remove view from stack after some delay. But it has some magic. For example 1 second delay works properly on iOS 18, but cause crash on iOS 16. 1 millisecond delay works on iOS 16, but sometimes didn't. self.path.append(newPathItem) DispatchQueue.main.asyncAfter(deadline: .now() + .milliseconds(1000)) { UIView.setAnimationsEnabled(false) self.path.remove(at: self.path.count - 2) DispatchQueue.main.asyncAfter(deadline: .now() + .milliseconds(1)) { UIView.setAnimationsEnabled(true) } } It is easy task to replace current top screen in UINavigationController of UIKit. How I can do it properly in SwiftUI and save animation?

As you can see in the screenshot, the verification popups that appear when making a StoreKit purchase cut off the buttons. When typing the code into the input field, the window will also flicker and stutter with random view refreshes. Is this something I can configure/change? It's not a very pleasant experience for making an in app purchase.

QuickTime recording palette behaves in a way which I want to replicate in my desktop app - specifically the behaviour when switching spaces, it appears on top. Currently, my app appears on all spaces, and even over fullscreen applications BUT it already exists when I switch to the space, this feels disjointed. I can't find a solution to this behaviour. Here's the Window Collection Behaviours I've tried (on an NSPanel): FullScreenAuxiliary - appears over fullscreen apps. CanJoinAllSpaces - appears on all spaces. These two options make the dock show up on all spaces in the same position, but on each space they already exists. I've tried this behaviour too: MoveToActiveSpace - which as per docs would move the window into active space only when its reopened, mine stays open all the time. I can't find any more information on how QuickTime achieves this.

Hello, I implemented offerCodeRedemption recently on my app in my subscription/onboarding flow. When I did, it broke my camera functionality (elsewhere in the app; totally unrelated code). I was able to fix the issue when implementing the old "AppStore.presentOfferCodeRedeemSheet" code with UIKit. I'm not sure why this is happening, but it seemed like a bug to me.

A NavigationStack with a singular enum for .navigationDestination() works fine. Both NavigationLinks(value:) and directly manipulating the NavigationPath work fine for moving around views. Zero problems. The issue is when we instead use a NavigationSplitView, I've only dabbled with two-column splits (sidebar and detail) so far. Now, if the sidebar has its own NavigationStack, everything works nicely on an iPhone, but on an iPad, you can't push views onto the detail from the sidebar. (They're pushed on the sidebar) You can solve this by keeping a NavigationStack ONLY on the detail. Sidebar links now properly push onto the detail, and the detail can move around views by itself. However, if you mix NavigationLink(value:) with manually changing NavigationPath, it stops working with no error. If you only use links, you're good, if you only change the NavigationPath you're good. Mixing doesn't work. No error in the console either, the breakpoints hit .navigationDestination and the view is returned, but never piled up. (Further attempts do show the NavigationPath is being changed properly, but views aren't changing) This problem didn't happen when just staying on NavigationStack without a NavigationSplitView. Why mix? There's a few reasons to do so. NavigationLinks put the appropriate disclosure indicator (can't replicate its look 100% without it), while NavigationPaths let you trigger navigation without user input (.onChange, etc) Any insights here? I'd put some code samples but there's a metric ton of options I've tested 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

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 to decrease main window screen size when user open Immersive space in my project. Using frame i try it but it not updated main window size it just update view frame.

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'm testing using Group Activities and having no trouble iOS<->iOS or starting an activity on macOS and joining via iOS. However, when I start an activity and then try to join it from another macOS client, the starting side joins the session just fine, but the receiving side acts like I don't have the required app, even when it is already running. I see the active SharePlay icon in the menu bar, and the Current Activity is shown, but instead of an "Open" button there is a "MyApp Required" string and a "View" button that goes to the App Store. (Where the app is not available yet, as expected, since I'm still working on it.) There is no GroupSession started on that Mac yet, obviously. I'm looking for any hints to help debug what is going on. How does Group Activities find the app for the activity on macOS and how can I figure out why it isn't finding mine? Thanks!

Hello, I've managed to get rid of these spaces in different ways. Using scrollview, giving negative insets, rewriting modifiers from scratch with plain style etc. But I couldn't solve this with a simple solution. I've read comments from many people experiencing similar problems online. It seems like there isn't a simple modifier to remove these spaces when we use sidebar as the list style in SwiftUI, or I couldn't find the simple solution. I wonder what's the simplest and correct way to reset these spaces? let numbers = Array(1...5) @State private var selected: Int? var body: some View { List(numbers, id: \.self, selection: $selected) { number in HStack { Text("Test") Spacer() } .frame(maxWidth: .infinity, alignment: .leading) } .listStyle(.sidebar) } }

Background Color Issue in Custom Keyboard Extension in Dark Mode for iOS 18.4.1 Issue Description I'm developing a custom keyboard extension for iOS 18.4.1 and experiencing an issue with background colors when using Dark Mode. After a user makes a selection from a menu in the keyboard, the background color of a view unexpectedly changes to white instead of maintaining the dark theme color. Steps to Reproduce Enable Dark Mode on the device Activate the custom keyboard in any text field Perform a specific interaction (selecting an item from a menu) After selection, the background of the view turns white instead of remaining dark Technical Details The issue appears to be related to UIScrollView's background color behavior The problem doesn't occur on initial display of the menu, only after user interaction I've attempted to set background colors explicitly on the view hierarchy, but the issue persists Environment iOS 18.4.1 Xcode 16.0 Custom keyboard extension Questions Has anyone encountered similar issues with view background colors changing after user interactions in keyboard extensions on iOS 18.4.1? Is there a recommended approach to maintain dark background colors in keyboard extensions after user selections? Could this be related to a change in how UIScrollView handles background colors in recent iOS versions? Thank you for any assistance or insights.

Dear all, Sorry if the topic has already been commented but I could not be able to find it in over 10,000 picks using the forum search field... My problem is that with any NSTextField in my app, a click will result in a memory leak. There is no code attached, just bindings to NSNumber properties. How can I fix this ? Thanks for your help. Best regards Chris

WKWebView cannot load and display HTTP image resources

I have a view with some buttons, and add 2 gestures using simultaneously. My app works well when built with XCode less than 16, or run on iOS less than 18.0. Example code is below: VStack(spacing: 0) { Button { print("button tapped") } label: { Rectangle() .foregroundColor(.red) } .frame(height: 100) } .gesture( DragGesture(minimumDistance: 0) .onEnded { value in print("single tap") } .simultaneously(with: TapGesture(count: 2).onEnded { print("double tap") } ) ) .frame(width: 200, height: 200) .border(Color.purple) I expect the action on Button should be recognized and print out button tapped, but only single tap and double tap are recognized

I've encountered an issue where using @Observable in SwiftUI causes extra initializations and deinitializations when a reference type is included as a property inside a struct. Specifically, when I include a reference type (a simple class Empty {}) inside a struct (Test), DetailsViewModel is initialized and deinitialized twice instead of once. If I remove the reference type, the behavior is correct. This issue does not occur when using @StateObject instead of @Observable. Additionally, I've submitted a feedback report: FB16631081. Steps to Reproduce Run the provided SwiftUI sample code (tested on iOS 18.2 & iOS 18.3 using Xcode 16.2). Observe the console logs when navigating to DetailsView. Comment out var empty = Empty() in the Test struct. Run again and compare console logs. Change @Observable in DetailsViewModel to @StateObject and observe that the issue no longer occurs. Expected Behavior The DetailsViewModel should initialize once and deinitialize once, regardless of whether Test contains a reference type. Actual Behavior With var empty = Empty() present, DetailsViewModel initializes and deinitializes twice. However, if the reference type is removed, or when using @StateObject, the behavior is correct (one initialization, one deinitialization). Code Sample import SwiftUI enum Route { case details } @MainActor @Observable final class NavigationManager { var path = NavigationPath() } struct ContentView: View { @State private var navigationManager = NavigationManager() var body: some View { NavigationStack(path: $navigationManager.path) { HomeView() .environment(navigationManager) } } } final class Empty { } struct Test { var empty = Empty() // Comment this out to make it work } struct HomeView: View { private let test = Test() @Environment(NavigationManager.self) private var navigationManager var body: some View { Form { Button("Go To Details View") { navigationManager.path.append(Route.details) } } .navigationTitle("Home View") .navigationDestination(for: Route.self) { route in switch route { case .details: DetailsView() .environment(navigationManager) } } } } @MainActor @Observable final class DetailsViewModel { var fullScreenItem: Item? init() { print("DetailsViewModel Init") } deinit { print("DetailsViewModel Deinit") } } struct Item: Identifiable { let id = UUID() let value: Int } struct DetailsView: View { @State private var viewModel = DetailsViewModel() @Environment(NavigationManager.self) private var navigationManager var body: some View { ZStack { Color.green Button("Show Full Screen Cover") { viewModel.fullScreenItem = .init(value: 4) } } .navigationTitle("Details View") .fullScreenCover(item: $viewModel.fullScreenItem) { item in NavigationStack { FullScreenView(item: item) .navigationTitle("Full Screen Item: \(item.value)") .toolbar { ToolbarItem(placement: .cancellationAction) { Button("Cancel") { withAnimation(completionCriteria: .logicallyComplete) { viewModel.fullScreenItem = nil } completion: { var transaction = Transaction() transaction.disablesAnimations = true withTransaction(transaction) { navigationManager.path.removeLast() } } } } } } } } } struct FullScreenView: View { @Environment(\.dismiss) var dismiss let item: Item var body: some View { ZStack { Color.red Text("Full Screen View \(item.value)") .navigationTitle("Full Screen View") } } } Console Output With var empty = Empty() in Test DetailsViewModel Init DetailsViewModel Init DetailsViewModel Deinit DetailsViewModel Deinit Without var empty = Empty() in Test DetailsViewModel Init DetailsViewModel Deinit Using @StateObject Instead of @Observable DetailsViewModel Init DetailsViewModel Deinit Additional Notes This issue occurs only when using @Observable. Switching to @StateObject prevents it. This behavior suggests a possible issue with how SwiftUI handles reference-type properties inside structs when using @Observable. Using a struct-only approach (removing Empty class) avoids the issue, but that’s not always a practical solution. Questions for Discussion Is this expected behavior with @Observable? Could this be an unintended side effect of SwiftUI’s state management? Are there any recommended workarounds apart from switching to @StateObject? Would love to hear if anyone else has run into this or if Apple has provided any guidance!

In the header for UIViewController, the method dismissViewControllerAnimated is declared like this: - (void)dismissViewControllerAnimated: (BOOL)flag completion: (void (^ __nullable)(void))completion NS_SWIFT_DISABLE_ASYNC API_AVAILABLE(ios(5.0)); NS_SWIFT_DISABLE_ASYNC means that there's no async version exposed like there would normally be of a method that exposes a completion handler. Why is this? And is it unwise / unsafe for me to make my own async version of it using a continuation? My use case is that I want a method that will sequentially dismiss all view controllers presented by a root view controller. So I could have this extension on UIViewController: extension UIViewController { func dismissAsync(animated: Bool) async { await withCheckedContinuation { continuation in self.dismiss(animated: animated) { continuation.resume() } } } func dismissPresentedViewControllers() async { while self.topPresentedViewController != self { await self.topPresentedViewController.dismissAsync(animated: true) } } var topPresentedViewController: UIViewController { var result = self while result.presentedViewController != nil { result = result.presentedViewController! } return result }

I have a SwiftUI project which has the following hierarchy: IOSSceneDelegate (App target) - depends on EntryPoint and Presentation static libs. Presentation (Static library) - Depends on EntryPoint static lib. Contains UI related logic and updates the UI after querying the data layer. EntryPoint (Static library) - Contains the entry point, AppDelegate (for its lifecycle aspects) etc. I've only listed the relevant targets here. SceneDelegate was initially present in EntryPoint library, because the AppDelegate references it when a scene is created. public func application(_ application: UIApplication, configurationForConnecting connectingSceneSession: UISceneSession, options: UIScene.ConnectionOptions) -&gt; UISceneConfiguration { // Set the SceneDelegate dynamically let sceneConfig: UISceneConfiguration = UISceneConfiguration(name: "mainWindow", sessionRole: connectingSceneSession.role) sceneConfig.delegateClass = SceneDelegate.self return sceneConfig } The intent is to move the SceneDelegate to the Presentation library. When moved, the EntryPoint library fails to compile because it's referencing the SceneDelegate (as shown above). To remove this reference, I tried to set up the SceneDelegate in the old way - In the info.plist file, mention a SceneConfiguration and set the SceneDelegate in Presentation. // In the Info.plist file &lt;key&gt;UIApplicationSceneManifest&lt;/key&gt; &lt;dict&gt; &lt;key&gt;UIApplicationSupportsMultipleScenes&lt;/key&gt; &lt;true/&gt; &lt;key&gt;UISceneConfigurations&lt;/key&gt; &lt;dict&gt; &lt;key&gt;UIWindowSceneSessionRoleApplication&lt;/key&gt; &lt;array&gt; &lt;dict&gt; &lt;key&gt;UISceneConfigurationName&lt;/key&gt; &lt;string&gt;Default Configuration&lt;/string&gt; &lt;key&gt;UISceneDelegateClassName&lt;/key&gt; &lt;string&gt;Presentation.SceneDelegate&lt;/string&gt; &lt;/dict&gt; &lt;/array&gt; &lt;/dict&gt; &lt;/dict&gt; // In the AppDelegate public func application(_ application: UIApplication, configurationForConnecting connectingSceneSession: UISceneSession, options: UIScene.ConnectionOptions) -&gt; UISceneConfiguration { // Refer to a static UISceneconfiguration listed in the info.plist file return UISceneConfiguration(name: "Default Configuration", sessionRole: connectingSceneSession.role) } As shown above, the Presentation.SceneDelegate is referred in the Info.plist file and the reference is removed from the AppDelegate (in EntryPoint library). The app target compiles, but when I run it, the SceneDelegate is not invoked. None of the methods from the SceneDelegate (scene(_:willConnectTo:options:), sceneDidDisconnect(_:), sceneDidEnterBackground(_:) etc.) are invoked. I only get the AppDelegate logs. It seems like the Configuration is ignored because it was incorrect. Any thoughts? Is it possible to move the SceneDelegate in this situation?
