I am reporting a regression/behavioral change in the SwiftUI layout engine when building with Xcode 26 (iOS 26 SDK). In previous versions (Xcode 15/16 and iOS 17/18 SDKs), a TabView using .tabViewStyle(.page(indexDisplayMode: .never)) correctly respected the coordinate space when combined with .edgesIgnoringSafeArea(.vertical). However, when compiling with the iOS 26 SDK, the internal views of the TabView render "out of bounds," pushing content vertically beyond the intended safe area boundaries and causing UI overlapping/clipping - an abnormal behavior. TabView(selection: $selectedIndex) { ForEach(0..<data.count, id: \.self) { index in nextPreviousHandlerView(id: data[index]) .tag(index) } } .tabViewStyle(.page(indexDisplayMode: .never)) .edgesIgnoringSafeArea(.vertical) // Causes vertical "jump" out of bounds in Xcode 26

Hello every developers. I need your help. Do you know how to attach animation to appearance, like a smooth transition from dark to light and vise versa. My code here: @main struct The_Library_of_BabelonApp: App { @AppStorage("selectedAppearance") private var selectedAppearance = 0 @StateObject private var router = AppRouter() var scheme: ColorScheme? { if selectedAppearance == 1 { return .light } if selectedAppearance == 2 { return .dark } return nil } var body: some Scene { WindowGroup { RootView() .preferredColorScheme(scheme) .environmentObject(router) // this is doesn't work correctly .animation(.smooth(duration: 2), value: selectedAppearance) } } } And my appearance switching looks: struct SettingsView: View { @AppStorage("selectedAppearance") private var selectedAppearance = 0 var body: some View { List { Section(header: Text("Appearance")) { HStack(spacing: 20) { ThemePreview(title: "Light", imageName: "lightTheme", tag: 1, selection: $selectedAppearance) ThemePreview(title: "Dark", imageName: "darkTheme", tag: 2, selection: $selectedAppearance) ThemePreview(title: "System", imageName: "systemMode", tag: 0, selection: $selectedAppearance) } .padding(.vertical, 10) .frame(maxWidth: .infinity) } } } } struct ThemePreview: View { let title: String let imageName: String let tag: Int @Binding var selection: Int var body: some View { Button { selection = tag } label: { VStack { Image(imageName) .resizable() .aspectRatio(contentMode: .fill) .frame(width: 120, height: 80) .clipShape(RoundedRectangle(cornerRadius: 12)) .overlay( RoundedRectangle(cornerRadius: 12) .stroke(selection == tag ? Color.blue : Color.clear, lineWidth: 3) ) Text(title) .font(.caption) .foregroundColor(selection == tag ? .blue : .primary) } } .buttonStyle(.plain) } } I guess my code works but animation working another way, its turn my Section, I don't know.... Thank you in advance

When you use .navigationTransition(.zoom(sourceID: "placeholder", in: placehoder)) for navigation animation, going back using the swipe gesture is still very buggy on IOS26. I know it has been mentioned in other places like here: https://developer.apple.com/forums/thread/796805?answerId=856846022#856846022 but nothing seems to have been done to fix this issue. Here is a video showing the bug comparing when the back button is used vs swipe to go back: https://imgur.com/a/JgEusRH I wish there was a way to at least disable the swipe back gesture until this bug is fixed.

I am currently trying to get my app ready for full external keyboard support, while testing I found an issue with the native DatePicker. Whenever I enter the DatePicker with an external keyboard it only jumps to the time picker and I am not able to move away from it. Arrow keys don't work, tab and control + tab only move me to the toolbar and back. This is how they look like private var datePicker: some View { DatePicker( "", selection: date, in: minDate..., displayedComponents: [.date] ) .fixedSize() .accessibilityIdentifier("\(datePickerLabel).DatePicker") } private var timePicker: some View { DatePicker( "", selection: date, in: minDate..., displayedComponents: [.hourAndMinute] ) .fixedSize() .accessibilityIdentifier("\(datePickerLabel).TimePicker") } private var datePickerLabelView: some View { Text(datePickerLabel.localizedString) .accessibilityIdentifier(datePickerLabel) } And we implement it like this in the view: HStack { datePickerLabelView Spacer() datePicker timePicker } Does anyone know how to fix this behavior? Is it our fault or is it the system? The issue comes up both in iOS 18 and 26.

Hi, new developer here. I have an issue where an image I have on app is not showing up on some devices. The image is: Resources/Assets/logo: I am using it in my app like: ZStack { Color.white .ignoresSafeArea() VStack { Spacer() Image("logo") Spacer() Text(dateString) .font(.custom("LinLibertine", size: 17)) .fontWeight(.bold) .tracking(5) .padding(.bottom, 50) } } The image appears fine on all simulators. And also on my real device iPad with A14. But when I run it on iPhone 8 or iPad Air M4, it shows empty space in place of image. I tried many different options like: Image("logo") .renderingMode(.original) .resizable() .scaledToFit() frame(width: 300) .background(Color.red.opacity(0.3)) But nothing works. What can be the issue?

Hello dear developers! Recently, I stumbled upon some really strange behavior of SwiftUI and I’m very curious why it works this way struct ContentView: View { @State private var title: String? @State private var isSheetPresented: Bool = false var body: some View { Button("Hello, world!") { title = "Sheet title" isSheetPresented = true } .sheet(isPresented: $isSheetPresented, content: { if let title { Text(title) } else { EmptyView() } }) } } Why in this case when we tap the button and sheet comes in we go to the branch else even though we set title before isSheetPresented but it still somehow nil But what really drive me crazy is that if we change a little bit code to this: I just added another @State property 'number' and use it as the Button's title. In this scenario it works 😃 and Text in the sheet view appearing struct ContentView: View { @State private var title: String? @State private var number = 0 @State private var isSheetPresented = false var body: some View { Button("\(number)") { title = "Sheet title" number += 0 isSheetPresented = true } .sheet(isPresented: $isSheetPresented, content: { if let title { Text(title) } else { EmptyView() } }) } } Is this somehow related to what happens under the hood like View Tree and Render Tree (Attribute Graph)? Maybe because ContentView’s body doesn't capture title it cannot be stored in the Render Tree so it always would have the initial value of nil? if there are any well-informed folks here, please help me figure out this mystery, I’d appreciate it!!! p.s. Don’t get me wrong. Im not interested in how to make it work. I’m interested in why this doesn’t work and what really happens under the hood that led to this result

I am developing an iOS App for a Bluetooth peripheral using SwiftUI with Swift 5 or 6. I have a few past attempts that got so far (connected to a peripheral), and some downloaded examples that connect to peripherals. Lately (last month or so), my current attempt never gets BleManager to start, and every attempt ends at my View that says 'please enable Bluetooth'. The Xcode console is totally blank with no print outputs. Coding Assistant suggested the init() in my @main structure could contain print("App initializing"), but even that never prints. Coding Assistant suggests: "• Open your project's Info.plist in Xcode. • Make sure UIApplicationSceneManifest is present and configured for SwiftUI, not referencing any storyboard. • Ensure UIMainStoryboardFile is not present (or blank)." but there is no info.plist because it is no longer required. Downloaded sample code runs and connects to peripherals, so Bluetooth is working on my iPhone and the Bluetooth device is accessible. My older attempts used to work, but now have the same problem. All attempts have "Enable Bluetooth to connect to Device" in the Privacy - Bluetooth Info.plist setting. Something is fundamentally wrong with many different code attempts. I have searched all the various settings for mention of SwiftUI or Storyboard, but not found them in working or failing projects. The downloaded code which works has minimum deployment iOS 14.0 and Swift Compiler Language Version Swift 5. My latest code attempt has minimum deployment iOS 16 and Swift 5. All code is target device iPhone (I am testing on iPhone 16e running iOS 26.2.1) and developing with Xcode 26.2 on MacBook Air M1 running the latest Tahoe. I do a Clean Build Folder before every test, and have tried re-starting both Mac and iPhone. How can my coding fail so spectacularly?

Hello. We are facing very silent and hardly replicable issue. All UserDefaults.standard data the application saved and was using to determine the state of app is lost and app behaves as if it was freshly installed. The issue always occurs only if we leave app on background for long time or if we manually swipe the app from the background apps. In case we swipe, this issue can occur in minutes, hours or up to 2 days by our latest testing. One important factor is that the app was developed using iOS18 in which issue never occured. Next it was being tested on iOS26 and it did everytime. Any currently available version of iOS26 reported this issue, all the way up to 26.2.1 (23C71). Our application is going through major upgrade of its whole lifecycle and services so it is possible this issue is caused by a bug in development as the production version does not report this issue neither on iOS26 of any version. The following list contains how we tried to fix this issue but none of which helped. App prewarming in the background (postpone all initialization including searching UserDefaults.standard for when isProtectedDataAvailable) Calling UserDefaults.standard.synchronize() everytime after saving data despite it is not recomended Built app using different SDK's (tested on iOS18 and iOS26 SDK) Distributed the app from local machine aswell as on TestFlight itself We searched through currently opened and closed issues for third-party libraries app uses regarding 'iOS26' and 'UserDefaults', especially those who were added recently with no success. The structure using which we save data into UserDefaults.standard did not change, we have only added few more settings to save through the lifecycle of the app after update. We estimate the overall increase is merely 30% more of what it used to be in previous version. Any ideas are much appreciated. We are considering to use different or fully custom ways to store app's settings.

I've coded a text-adventure game in SwiftUI. (My game has no graphics or sound effects.) My app already supports keyboard navigation; I would like to add support for game controllers on iPhone. I can't figure out how to do it. I especially can't see any way to allow controller users to enter text in a TextField. I've read https://developer.apple.com/documentation/gamecontroller/supporting-game-controllers and it's all about button events. There's no reference to SwiftUI at all in that documentation, or any input-method editing at all. The only mention of "keyboard" is about treating the keyboard itself as if it were a game controller providing button events. How do I implement this?

I have the following snippet (but you can see my entire code in GitHub, if you want): LazyVGrid(columns: columns) { ForEach(books) { book in BookView(book: book) .draggable(Book.BookTransferable(persistanceIdentifier: book.id)) } } and BookView is: VStack { Image(nsImage: book.image) .resizable() .frame(width: 150, height: 200) .scaledToFill() Text(book.title) .lineLimit(1) .font(.headline) HStack { ForEach(book.tags.sorted(), id: \.self) { tag in TagView(tag: tag, showText: false) } } } .padding() This will render each BookView on a different base-line because of the fact that the Text view sometimes takes 1, 2 or even 3 lines (as shown). How can I have all BookViews alligned at a common base-line (as it would if Text would only take one line, for example)?

I’m seeing a camera/capture routing issue on visionOS when multiple WindowGroups are open at the same time. I have a SwiftUI view that starts an AVCaptureSession on onAppear and stops it on onDisappear. The camera feed is displayed in a subview that only exists inside one window. However, when I open additional windows (other WindowGroups) in the same app, the camera perspective/route changes unexpectedly — it looks like the capture is being re-associated with a different scene/window, even though the camera view never moved and no other view starts capture. Expected behavior Opening additional windows should not affect the active capture session or camera routing for the existing camera view. The camera feed should remain stable and tied to the window hosting. Actual behavior When multiple windows are open, the camera feed “switches perspective” / appears to re-route, as if the system changes which scene is considered active for capture. This happens without any explicit code calling startSession() again and without the camera view being present in the other windows. Additional context This app is running in an unbounded scene and uses Unity PolySpatial.

VideoMaterial Black Screen on Vision Pro Device (Works in Simulator) App Overview App Name: Extn Browser Bundle ID: ai.extn.browser Purpose: A visionOS web browser that plays 360°/180° VR videos in an immersive sphere environment Development Environment & SDK Versions Component Version Xcode 26.2 Swift 6.2 visionOS Deployment Target 26.2 Swift Concurrency MainActor isolation enabled App is released in the TestFlight. Frameworks Used SwiftUI - UI framework RealityKit - 3D rendering, MeshResource, ModelEntity, VideoMaterial AVFoundation - AVPlayer, AVAudioSession WebKit - WKWebView for browser functionality Network - NWListener for local proxy server Sphere Video Mechanism The app creates an immersive 360° video experience using the following approach: // 1. Create sphere mesh (10 meter radius for immersive viewing) let mesh = MeshResource.generateSphere(radius: 10.0) // 2. Create initial transparent material var material = UnlitMaterial() material.color = .init(tint: .clear) // 3. Create entity and invert sphere (negative X scale) let sphere = ModelEntity(mesh: mesh, materials: [material]) sphere.scale = SIMD3<Float>(-1, 1, 1) // Inverts normals for inside-out viewing sphere.position = SIMD3<Float>(0, 1.5, 0) // Eye level // 4. Create AVPlayer with video URL let player = AVPlayer(url: videoURL) // 5. Configure audio session for visionOS let audioSession = AVAudioSession.sharedInstance() try audioSession.setCategory(.playback, mode: .moviePlayback, options: [.mixWithOthers]) try audioSession.setActive(true) // 6. Create VideoMaterial and apply to sphere let videoMaterial = VideoMaterial(avPlayer: player) if var modelComponent = sphere.components[ModelComponent.self] { modelComponent.materials = [videoMaterial] sphere.components.set(modelComponent) } // 7. Start playback player.play() ImmersiveSpace Configuration // browserApp.swift ImmersiveSpace(id: appModel.immersiveSpaceID) { ImmersiveView() .environment(appModel) } .immersionStyle(selection: .constant(.mixed), in: .mixed) Entitlements <!-- browser.entitlements --> <key>com.apple.security.app-sandbox</key> <true/> <key>com.apple.security.network.client</key> <true/> <key>com.apple.security.network.server</key> <true/> Info.plist Network Configuration <key>NSAppTransportSecurity</key> <dict> <key>NSAllowsArbitraryLoads</key> <true/> </dict> The Issue Behavior in Simulator: Video plays correctly on the inverted sphere surface - 360° video is visible and wraps around the user as expected. Behavior on Physical Vision Pro: The sphere displays a black screen. No video content is visible, though the sphere entity itself is present. Important: Not a DRM/Licensing Issue This issue is NOT related to Digital Rights Management (DRM) or FairPlay. I have tested with: Unlicensed raw MP4 video files (no DRM protection) Self-hosted video content with no copy protection Direct MP4 URLs from CDN without any licensing requirements The same black screen behavior occurs with all unprotected video sources, ruling out DRM as the cause. (Plain H.264 MP4, no DRM) Screen Recording: Working in Simulator The following screen recording demonstrates playing a 360° YouTube video in the immersive sphere on the visionOS Simulator: https://cdn.commenda.kr/screen-001.mov This confirms that the VideoMaterial and sphere rendering work correctly in the simulator, but the same setup shows a black screen on the physical Vision Pro device. Observations AVPlayer status reports .readyToPlay - The video appears to load successfully VideoMaterial is created without errors - No exceptions thrown Sphere entity renders - The geometry is visible (black surface) Audio session is configured - No errors during audio session setup Network requests succeed - The video URL is accessible from the device Same result with local/unprotected content - DRM is not a factor Console Logs (Device) The logging shows: Sphere created and added to scene AVPlayer created with correct URL VideoMaterial created and applied Player status transitions to .readyToPlay player.play() called successfully Rate shows 1.0 (playing) Despite all success indicators, the rendered output is black. Questions for Apple Are there known differences in VideoMaterial behavior between the visionOS Simulator and physical Vision Pro hardware? Does VideoMaterial(avPlayer:) require specific video codec/format requirements that differ on device? (The test video is a standard H.264 MP4) Is there a required Metal capability or GPU feature for VideoMaterial that may not be available in certain contexts on device? Does the immersion style (.mixed) affect VideoMaterial rendering on hardware? Are there additional entitlements required for video texture rendering in RealityKit on physical hardware? Attempted Solutions Configured AVAudioSession with .playback category Added delay before player.play() to ensure material is applied Verified sphere scale inversion (-1, 1, 1) Tested multiple video URLs (including raw, unlicensed MP4 files) Confirmed network connectivity on device Ruled out DRM/FairPlay issues by testing unprotected content Environment Details Device: Apple Vision Pro visionOS Version: 26.2 Xcode Version: 26.2 macOS Version: Darwin 25.2.0

I have a desktop application developed in SwiftUI that shows property locations on the map. That's NOT the main feature. IF you give the application permission to access your location, the blue dot will appear on the map. If you don't, the blue user dot won't appear. That's the only difference with location services. In other words, the application has no use of user's current position beyond showing it on the map. Since it's just the matter of showing or not showing the blue dot on the map, the application doesn't really need to use the location service. Anyway, the reviewer is talking about something else by rejecting the application in two aspects. Guideline 5.1.1 - Legal - Privacy - Data Collection and Storage Guideline 5.1.5 - Legal - Privacy - Location Services As I said earlier, the application only wants to show the blue dot on the map so that you can see your property locations relative to your current location. In code, it's something like the following. Map(position: $propertyViewModel.mapPosition) { ForEach(propertyViewModel.properties) { property in Annotation("", coordinate: CLLocationCoordinate2D(latitude: property.lat, longitude: property.lon)) { ... } } UserAnnotation() } So I'm hit with two rejection reasons with this one line. UserAnnotation() And the reviewer is talking about something like the app is not functional when Location Services are disabled. To resolve this issue, please revise the app so that the app is fully functional without requiring the user to enable Location Services. Well, I can remove the UserAnnotation() line if I want to put this application through the review process. Nothing will become dysfunctional, though, if you decide to reject permission request. So would you remove it or would you play along with this reviewer if you were me? It's been three or four days since rejection. As you can imagine, the reviewer doesn't bother to answer as to What are the exact coordinates that the application has allegedly collected What won't work as a result of location permission request refusal. This isn't the first time I get my app rejected. I've probably had 150 to 200 of them rejected in the past 15 years. And just because a reviewer rejects your app for a bizarre reason, would you give in? Remove this feature and that feature because the reviewer is incompetent such that he or she makes his or her decision based on imagination? What do you think?

In the iOS 13 world, I had code like this: class SceneDelegate: UIResponder, UIWindowSceneDelegate { &#9;&#9;func windowScene(_ windowScene: UIWindowScene, userDidAcceptCloudKitShareWith cloudKitShareMetadata: CKShare.Metadata) { &#9;&#9;&#9;&#9;// do stuff with the metadata, eventually call CKAcceptSharesOperation &#9;&#9;} } I am migrating my app to the new SwiftUI app lifecycle, and can’t figure out where to put this method. It used to live in AppDelegate pre-iOS13, and I tried going back to that, but the AppDelegate version never gets called. There doesn’t seem to be a SceneDelegateAdaptor akin to UIApplicationDelegateAdaptor available, which would provide a bridge to the old code. So, I’m lost. How do I accept CloudKit shares with SwiftUI app lifecycle? 🙈

This is a very basic macOS Finder-style test app using AppKit. I am experiencing a "jump" in the vertical scroll position of my NSTableView (inside an NSScrollView) specifically when the window is resized horizontally. This happens when columns are visually added or removed. Framework: AppKit (Cocoa) Xcode/macOS: 26.2 Code: https://github.com/MorusPatre/Binder/blob/main/ContentView%20-%20Scroll%20Jump%20during%20Resize.swift

I have a UIHostingController on which I have set: hostingController.sizingOptions = [.intrinsicContentSize] The size of my SwiftUI content changes with animation (I update a @Published property on an ObservableObject inside a withAnimation block). However, I notice that my hostingController.view just jumps to the new frame without animating the change. Question: how can I animate the frame changes in UIHostingController that are caused by sizingOptions = [.intrinsicContentSize]

My app has a collection of Cell Views. some of the views' model objects include a Player, and others do not. I want to use drag and drop to move a player from one cell to another. I only want cells that contain a player to be valid drag sources. All cells will be valid drop destinations. When I uncomment the .disabled line both drag and drop become disabled. Is it possible to keep a view enabled as a dropDestination but disabled as a draggable source? VStack { Image("playerJersey_red") if let player = content.player { Text(player.name) } } .draggable(content) // .disabled(content.player == nil) .dropDestination(for: CellContent.self) { items, location in One thing I tried was to wrap everything in a ZStack and put a rectangle with .opacity(0.02) above the Image/Text VStack. I then left draggable modifying my VStack and moved dropDestination to the clear rectangle. This didn't work as I wasn't able to initiate a drag when tapping on the rectangle. Any other ideas or suggestions? thanks

Hey all, I found a weird behaviour with the searchable component. I created a custom bottom nav bar (because I have custom design in my app) to switch between screens. On one screen I display a List component with the searchable component. Whenever I enter the search screen the first time, the searchable component is displayed at the bottom. This is wrong. It should be displayed at the top under the navigationTitle. When I enter the screen a second time, everything is correct. This behaviour can be reproduced on all iOS 26 versions on the simulator and on a physical device with debug and release build. On iOS 18 everything works fine. Steps to reproduce: Cold start of the app Click on Search TabBarIcon (searchable wrong location) Click on Home TabBarIcon Click on Search TabBarIcon (searchable correct location) Simple code example: import SwiftUI struct ContentView: View { @State var selectedTab: Page = Page.main var body: some View { NavigationStack { ZStack { VStack { switch selectedTab { case .main: MainView() case .search: SearchView() } } VStack { Spacer() VStack(spacing: 0) { HStack(spacing: 0) { TabBarIcon(iconName: "house", selected: selectedTab == .main, displayName: "Home") .onTapGesture { selectedTab = .main } TabBarIcon(iconName: "magnifyingglass", selected: selectedTab == .search, displayName: "Search") .onTapGesture { selectedTab = .search } } .frame(maxWidth: .infinity) .frame(height: 55) .background(Color.gray) } .ignoresSafeArea(.all, edges: .bottom) } } } } } struct TabBarIcon: View { let iconName: String let selected: Bool let displayName: String var body: some View { ZStack { VStack { Image(systemName: iconName) .resizable() .renderingMode(.template) .aspectRatio(contentMode: .fit) .foregroundColor(Color.black) .frame(width: 22, height: 22) Text(displayName) .font(Font.system(size: 10)) } } .frame(maxWidth: .infinity) } } enum Page { case main case search } struct MainView: View { var body: some View { VStack { Image(systemName: "globe") .imageScale(.large) .foregroundStyle(.tint) Text("Hello, world!") } .padding() .navigationTitle("Home") } } struct SearchView: View { @State private var searchText = "" let items = [ "Apple", "Banana", "Pear", "Strawberry", "Orange", "Peach", "Grape", "Mango" ] var filteredItems: [String] { if searchText.isEmpty { return items } else { return items.filter { $0.localizedCaseInsensitiveContains(searchText) } } } var body: some View { List(filteredItems, id: \.self) { item in Text(item) } .navigationTitle("Fruits") .searchable(text: $searchText, placement: .navigationBarDrawer(displayMode: .always), prompt: "Search") } }

I first started using the SwiftUI pushWindow API in visionOS 26.2, and I've reported several bugs I discovered, listed below. Under certain circumstances, pushed window relationships may break, and this behavior affects all other apps, not just the app that caused the problem, until the next device reboot. In other cases, the system may crash and restart. (FB21287011) When a window presented with pushWindow is dismissed, its parent window reappears in the wrong location (FB21294645) Pinning a pushed window to a wall breaks pushWindow for all other apps on the system (FB21594646) pushWindow interacts poorly with the window bar close app option (FB21652261) If a window locked to a wall calls pushWindow, the original window becomes unlocked (FB21652271) If a window locked in place calls pushWindow and the pushed window is closed, the system freezes (FB21828413) pushWindow, UIApplication.open, and a dismissed immersive space result in multiple failures that require a device reboot (FB21840747) visionOS randomly foregrounds a backgrounded immersive space app with a pushed window's parent window visible instead of the pushed window (FB21864652) When a running app is selected in the visionOS home view, windows presented with pushWindow spontaneously close (FB21873482) Pushed windows use the fixed scaling behavior instead of the dynamic scaling behavior I'm posting the issues here in case this information is helpful to other developers. I'd also like to hear about other pushWindow issues developers have encountered, so I can watch out for them. Questions: I've discovered that some of the issues above can be partially worked around by applying the defaultLaunchBehavior and restorationBehavior scene modifiers to suppress window restoration and locking, which pushWindow appears to interact poorly with. Are there other recommended workarounds? I've observed that the Photos and Settings apps, which predate the pushWindow API, are not affected by the issues I reported. Are there other more reliable ways I could achieve the same behavior as pushWindow without relying on that API? I'd appreciate any guidance Apple engineers could provide. Thank you.

Context: I am building a macOS file (currently image only) browser using SwiftUI. The core view is a ScrollView containing a LazyVGrid. The layout is dynamic: as the window resizes, I calculate the optimal number of columns and spacing using a GeometryReader. The Issue: While scrolling is pretty smooth (thanks to custom image caching and prefetching), window resizing is significantly laggy. After having scrolled the UI stutters and drops frames heavily while dragging the window edge. The Code: https://github.com/MorusPatre/Binder
