I'm using one UITabBarController which leads to 6 NavigationController. Therefore the user will get 4 icons displayed and one icon with three points to see the rest of the Navigation Controller. If the user now tries to edit the list and moves one item from the hidden area towards the TabBar at the bottom, the App crashes with the error: Exception NSException * "Can't add self as subview" 0x0000600000d16040 I can see this effect at least on both my apps. If the same compilation is run on a older iOS version, there is no crash. Is there anything I have to take care of the configuration of the TabBar, when it comes to iOS26?

"Use location, address and addressRepresentations instead" Is it possible to know what kind of "Address" a MapItem is representing (State, County, Neighborhood etc) after a MKGeocodingRequest? Is it possible to find out the CLRegion or similar of an map item. (Now when we cannot read it from the Placemark)

In tvOS 18 the onMoveCommand is missing the first press after a view is loaded and every time the direction is changed. It also misses the first press on a button after a focus change. This appears to only impact the newer silver remote and not the older black remote or IR remotes. With the code bellow press any direction 3 times and it will only log twice. struct ButtonTest: View { var body: some View { VStack { Button { debugPrint("button 1") } label: { Text("Button 1") } Button { debugPrint("button 2") } label: { Text("Button 2") } Button { debugPrint("button 3") } label: { Text("Button 3") } } .onMoveCommand(perform: { direction in debugPrint("move \(direction)") }) .padding() } }

I work on a universal app that targets both iPhone and iPad. Our iPad app currently requires full screen. When testing on the latest iPadOS 26 beta, we see the following warning printed to the console: Update the Info.plist: 1) `UIRequiresFullScreen` will soon be ignored. 2) Support for all orientations will soon be required. It will take a fair amount of effort to update our app to properly support presentation in a resizable window. We wanted to gauge how urgent this change is. Our testing has shown that iPadOS 26 supports our app in a non-resizable window. Can someone from Apple provide any guidance as to how soon “soon” is? Will UIRequiresFullScreen be ignored in iPadOS 26? Will support for all orientations be required in iPadOS 26?

My app is a SwiftUI document based app using DocumentGroupLaunchScene. In iOS(iPadOS) 18.4, when it launches, it has duplicate toolbar items, and when I close the current document and open other documents, it adds more duplicates. It also shows a wrong document name, which shows the first opened document name. This issue can be reproduced in the sample code (Building a document-based app with SwiftUI). I have submitted Feedback (FB17025216), but not sure if this is a known bug or if I'm missing anything.

Hello, I've a question about performance when trying to render lots of items coming from SwiftData via a @Query on a SwiftUI List. Here's my setup: // Item.swift: @Model final class Item: Identifiable { var timestamp: Date var isOptionA: Bool init() { self.timestamp = Date() self.isOptionA = Bool.random() } } // Menu.swift enum Menu: String, CaseIterable, Hashable, Identifiable { var id: String { rawValue } case optionA case optionB case all var predicate: Predicate<Item> { switch self { case .optionA: return #Predicate { $0.isOptionA } case .optionB: return #Predicate { !$0.isOptionA } case .all: return #Predicate { _ in true } } } } // SlowData.swift @main struct SlowDataApp: App { var sharedModelContainer: ModelContainer = { let schema = Schema([Item.self]) let modelConfiguration = ModelConfiguration(schema: schema, isStoredInMemoryOnly: false) return try! ModelContainer(for: schema, configurations: [modelConfiguration]) }() var body: some Scene { WindowGroup { ContentView() } .modelContainer(sharedModelContainer) } } // ContentView.swift struct ContentView: View { @Environment(\.modelContext) private var modelContext @State var selection: Menu? = .optionA var body: some View { NavigationSplitView { List(Menu.allCases, selection: $selection) { menu in Text(menu.rawValue).tag(menu) } } detail: { DemoListView(selectedMenu: $selection) }.onAppear { // Do this just once // (0..<15_000).forEach { index in // let item = Item() // modelContext.insert(item) // } } } } // DemoListView.swift struct DemoListView: View { @Binding var selectedMenu: Menu? @Query private var items: [Item] init(selectedMenu: Binding<Menu?>) { self._selectedMenu = selectedMenu self._items = Query(filter: selectedMenu.wrappedValue?.predicate, sort: \.timestamp) } var body: some View { // Option 1: touching `items` = slow! List(items) { item in Text(item.timestamp.description) } // Option 2: Not touching `items` = fast! // List { // Text("Not accessing `items` here") // } .navigationTitle(selectedMenu?.rawValue ?? "N/A") } } When I use Option 1 on DemoListView, there's a noticeable delay on the navigation. If I use Option 2, there's none. This happens both on Debug builds and Release builds, just FYI because on Xcode 16 Debug builds seem to be slower than expected: https://indieweb.social/@curtclifton/113273571392595819 I've profiled it and the SwiftData fetches seem blazing fast, the Hang occurs when accessing the items property from the List. Is there anything I'm overlooking or it's just as fast as it can be right now?

Filed in Feedback as FB20772137 Zoom transition originating from inside tabViewBottomAccessory, when the binding passed to fullScreenCover's item is a Binding other than a "$-synthesized" binding, the animation fails with the following error (and crucially fails to perform the desired animation): Starting a zoom transition from a nil view will trigger a fallback transition. To get the best possible teansition, be sure to provide a view that's visible and in a window. What I want to do is pass a binding to a property inside an ObservableObject (or @Observable, but it doesn't matter) to hold the item representing the presentation. But this stopped working as of 26.1b4. It worked in 26.1b3 and in 26.0 (and 26.0.1) Here's the gist of code that will reproduce the issue (I've omitted irrelevant details in the interest of brevity): struct ContentView: View { @Binding var presentation: PresentationDestination? @Namespace private var animation var body: some View { // Omitted TabView stuff… .tabViewBottomAccessory { miniPlayer .matchedTransitionSource( id: "player", in: animation ) } .fullScreenCover( item: $presentation, content: { _ in fullScreenPlayer .navigationTransition( .zoom( sourceID: "player", in: animation ) ) }) } As you can see, ContentView takes a Binding to the presentation, but it matters how this binding is constructed. This works: @State private var presentation: PresentationDestination … ContentView(presentation: $presentation) This fails (as does ObservableObject with @Published): @Observable class Router2 { var presentation: PresentationDestination? } … @State private var router2 = Router2() … ContentView(presentation: $router2.presentation) Also, this fails: @State private var presentation: PresentationDestination … ContentView( presentation: .init(get: { presentation }, set: { newValue in presentation = newValue }) ) These differences are unexpected, of course. I consider this a regression in 26.1b4 I should add that if I move the source of the transition to somewhere outside tabViewBottomAccessory things seem to work fine.

When I update a variable inside my model that is marked @Transient, my view does not update with this change. Is this normal? If I update a non-transient variable inside the model at the same time that I update the transient one, then both changes are propagated to my view. Here is an example of the model: @Model public class WaterData { public var target: Double = 3000 @Transient public var samples: [HKQuantitySample] = [] } Updating samples only does not propagate to my view.

Is there a way to display a .icon file in SwiftUI? I want to show the app icon in the app itself but exporting and including the app icon as a PNG feels redundant. This would consume a lot of unnecessary storage especially when including a lot of alternative app icons. There has to be a better way Otherwise I would file a feedback for that Thank you

We have crash reports as shown below that we haven't yet been able to repro and could use some help deubgging. My guess is that the app is giving a label or text view an attributed string with an invalid attribute range, but attributed strings are used in many places throughout the app, and I don't know an efficient way to track this down. I'm posting the stack trace here in hopes that someone more familiar with the internals of the system frameworks mentioned will be able to provide a clue to help narrow where I should look.

Playing around with the new TabViewBottomAccessoryPlacement API, but can't figure out how to update the value returned by @Environment(\.tabViewBottomAccessoryPlacement) var placement. I want to change this value programmatically, want it to be set to nil or .none on app start until user performs a specific action. (taps play on an item which creates an AVPlayer instance). Documentation I could find: https://developer.apple.com/documentation/SwiftUI/TabViewBottomAccessoryPlacement

Hi, I faced with the issue on iOS 26.1 with PHPickerViewController. After first selection I save assetIdentifier of PHPickerResult for images. next time I open the picker I expect to have the images selected based on assetIdentifier Code: var config = PHPickerConfiguration(photoLibrary: .shared()) config.selectionLimit = 10 config.filter = .images config.preselectedAssetIdentifiers = images.compactMap(\.assetID) let picker = PHPickerViewController(configuration: config) picker.delegate = self present(picker, animated: true) But on iOS 26.1 they aren't selected. On lower iOS version all works fine. Does anybody faced with similar issue?

Calling contactAccessPicker results in a blank sheet and a jetsam error, rather than the expected contact picker, using Apple’s sample code, only on device with iOS 26.2.1. This is happening on a iPhone 17 Pro Max running 26.2.1, and not on a simulator. I’m running Apple's sample project Accessing a person’s contact data using Contacts and ContactsUI Steps: Run the sample app on device running iOS 26.2.1. Use the flow to authorize .limited access with 1 contact: Tap request access, Continue, Select Contacts. Select a contact, Continue, Allow Selected Contact. This all works as expected. Tap the add contact button in the toolbar to add a second contact. Expected: This should show the Contact Access Picker UI. Actual: Sheet is shown with no contents. See screenshot of actual results on iOS device running 26.2.1. Reported as FB21812568 I see a similar (same?) error reported for 26.1. It seems strange that the feature is completely broken for multiple point releases. Is anyone else seeing this or are the two of us running into the same rare edge case? Expected Outcome, seen on simulator running 26.2 Actual outcome, seen on device running 26.2.1

i export apple SF as custom sf for test. code is simple: var body: some ControlWidgetConfiguration { StaticControlConfiguration( kind:"ControlWidgetConfiguration" ) { ControlWidgetButton(action: DynamicWidgetIntent()) { Text("test") Image("custom_like") } }.displayName("test") } as we can see, it can't show image in the preview. but it can show image in the Control widget center. am i do some thing wrong?

I'm working on a NavigationStack based app. Somewhere I'm using: @Environment(\.dismiss) private var dismiss and when trying to navigate to that view it gets stuck. I used Self._printChanges() and discovered the environment variable dismiss is changing repeatedly. Obviously I am not changing that variable explicitly. I wasn't able to reproduce this in a small project so far, but does anybody have any idea what kind of thing I could be doing that might be causing this issue? iOS 17.0.3

All of a sudden, after iOS 18.4 was released, I am having tons of navigation problems in my app in production. Buttons navigating to empty pages, views seeming to 'freeze', top navigation bar mismatched with the content of the page. It seems that iOS 18.4 broke a critical piece of UIKit + SwiftUI bridging functionality that my project relies on. ** Originally posted in 'Core OS' topic but realized 'UI Frameworks > General' made more sense. My bad. ** My application is written with both UIKit and SwiftUI components. Here is a breakdown of my setup: UIApplicationDelegate > UIWindow > rootViewController of window is a UITabBarController > each tab is a UINavigationController rootViewController of nav controller is a UIHostingController > rootView of the hosting controller is a SwiftUI View In my SwiftUI views, I have been using NavigationLink for horizontal 'push' style navigation in my SwiftUI views. I do not use NavigationView, I only rely on the bridging capabilities of UINavigationController to action on my NavigationLinks. This has never been an issue, until iOS 18.4 was released. Now, when running iOS 18.4, I am having all sorts of unexpected behavior in the UI. I will break down 2 of these use cases here: Use case A: In one of my SwiftUI views, I have a ForEach for which each element's view is a NavigationLink. This is using the NavigationLink(_ destination:,label:) initializer. Navigating forward from here works/looks normal. However, once I try to navigate backward from that destination (tap the 'Back' button in top left), the view goes blank and the navigation bar at the top of the page (which is maintained by the UINavigationController instance) does not change. If I call popToRootViewController on that nav controller, the navigation bar at the top of the page returns to its normal state, but the view is still blank. It is not until after I have called popToRootViewController, and then navigate to a different tab of the UITabBarController and return to the initial tab, does the SwiftuI content view (the one with the ForEach) finally redraw and the view hierarchy is restored. Here is a warning that is logged in the console when I tap the 'Back ' button: Top view controller's view unexpectedly not in window for navigation transition. Skipping layout. nav = <UINavigationController: 0x1110bbe00>, topVC = <TtGC7SwiftUI19UIHostingControllerV5MyApp10MyPage: 0x106814e00> EDIT: If I replace the NavigationLink with a call to UINavigationController.pushViewController, I am still seeing the exact same behavior. Pressing back button makes the view empty > need to pop to root view controller and switch tabs in order to restore the view. Use case B Another instance of this issue happens whenever I try to use a NavigationLink inside of a view that itself was the destination of a NavigationLink in its parent view (i.e.: Root view > detail view > sub-detail view). For example, take the detail view destination in use case A. I have tapped a NavigationLink from the ForEach and landed on the detail view. Again, so far things work/look normal. Now, if I tap on another NavigationLink from that detail view, the view does not transition to the new page. The top navigation bar does transition, and shows the title and actions associated with this second destination. However, the view of this second destination is not displayed. It is worth noting that the same warning I mentioned above is also logged when I tap the NavigationLink to navigate to this second destination. Top view controller's view unexpectedly not in window for navigation transition. Skipping layout. nav = <UINavigationController: 0x109859400>, topVC = <TtGC7SwiftUI19UIHostingControllerVVS_19BridgedPresentation8RootView: 0x300ab8000> Strangely, if I switch to a different tab of the UITabBarController and back to the initial tab, this second destination's view is successfully rendered. It seems that switching tabs in this UITabBarController is calling something in either SwiftUI or UIKit that is redrawing my views. Conclusion This is a serious issue with UIKit + SwiftUI bridging support. I have never had problems like this until devices started running iOS 18.4, and there is nothing in the iOS 18.4 changelog that suggests this was an intentional change. All of a sudden, after updating to the latest iOS version, my app is totally broken. I want to be clear that I'm not using deprecated NavigationLink methods in these instances. My app's minimum deployment target is iOS 16. I know that there are more modern navigation APIs like navigation stack, etc. I am looking for answers about my use case: whether it is officially unsupported as of iOS 18.4, whether this setup should be supported and this is indeed some sort of bug in iOS, or anything in-between. I'm happy to provide formatted code if needed for discussion purposes. This is about my entire app's view hierarchy so there are a lot of disparate lines of code that make up this problem.

Looking to see if anyone has experienced this issue, and is aware of any workarounds. With an app migrating towards SwiftUI Views but still using UIKit for primary navigation, my app makes use of UIHostingController to push SwiftUI Views onto a UINavigationController stack in a lot of areas. With iOS 26, I notice that SwiftUI's Menu view really struggles to present when contained in a UIHostingController. An error is logged to the console on presentation, and depending on the UI, the Menu won't present inside of it's container, or will jump around the screen. The bug, it seems is based in a private class UIReparentingView and I am curious if anyone has found a work around for this issue. The error reported is: Adding '_UIReparentingView' as a subview of UIHostingController.view is not supported and may result in a broken view hierarchy. Add your view above UIHostingController.view in a common superview or insert it into your SwiftUI content in a UIViewRepresentable instead. The simplest way to see this issue is to create a new storyboard based project. From the ViewController present a UIHostingController with a SwiftUI view that has a Menu and then simply tap to open the Menu. Thanks for any input!

Our app was just rejected by Apple because they say the subscription management sheet never loads. It just spins indefinitely. We're using StoreKit's manageSubscriptionsSheet view modifier to present the sheet, and it's always worked for us when testing in SandBox. Has anyone else had this problem? Given that it's Apple's own code that got us rejected, what's our path forward?

In my visionOS app, I'm seeing this error in the console dozens of times. Anyone know what it means, or how to troubleshoot it? Searching these forums and the usual other places hasn't come up with anything that seems relevant.

All of these issues appear when the search controller is set on the view controller's navigationItem and the search controller's searchBar has its scopeButtonTitles set. So far the following issues are affecting my app on iOS/iPadOS 26 as of beta 7: When the scopeBarActivation of UISearchController is set to .onSearchActivation, the preferredSearchBarPlacement of the navigationItem is set to .integratedButton, and the searchBarPlacementAllowsToolbarIntegration is set to false (forcing the search icon to appear in the nav bar), on both iPhones and iPads, the scope buttons never appear. They don't appear when the search is activated. They don't appear when any text is entered into the search bar. FB19771313 I attempted to work around that issue by setting the scopeBarActivation to .manual. I then show the scope bar in the didPresentSearchController delegate method and hide the scope bar in the willDismissSearchController. On an iPhone this works though the display is a bit clunky. On an iPad, the scope bar does appear via the code in didPresentSearchController, but when any scope bar button is tapped, the search controller is dismissed. This happens when the app is horizontally regular. When the app on the iPad is horizontally compact, the buttons work but the search bar's text is not correctly aligned within the search bar. Quite the mess really. I still need to post a bug report for this issue. But if issue 1 above is fixed then I don't need this workaround. When the scopeBarActivation of UISearchController is set to .onSearchActivation, the preferredSearchBarPlacement of the navigationItem is set to .stacked, and the hidesSearchBarWhenScrolling property of the navigationItem is set to false (always show the search bar), and this is all used in a UITableViewController, then upon initial display of the view controller on an iPhone or iPad, you are unable to tap on the first row of the table view except on the very bottom of the row. The currently hidden scope bar is stealing the touches. If you activate and then cancel the search (making the scope bar appear and then disappear) then you are able to tap on the first row as expected. The initially hidden scope bar also bleeds through the first row of the table. It's faint but you can tell it's not quite right. Again, this is resolved by activating and then canceling the search once. FB17888632 When the scopeBarActivation of UISearchController is set to .onSearchActivation, the preferredSearchBarPlacement of the navigationItem is set to integrated or .integratedButton, and the toolbar is shown, then on iPhones (where the search bar/icon appears in the toolbar) the scope buttons appear (at the top of the screen) the first time the search is activated. But if you cancel the search and then activate it again, the search bar never appears a second (or later) time. On an iPad the search bar/icon appears in the nav bar and you end up with the same issue as #1 above. FB17890125 Issues 3 and 4 were reported against beta 1 and still haven't been fixed. But if issue 1 is resolved on iPhone, iPad, and Mac (via Mac Catalyst), then I personally won't be affected by issues 2, 3, or 4 any more (but of course all 4 issues need to be fixed). And by resolved, I mean that the scope bar appears and disappears when it is supposed to each and every time the search is activated and cancelled (not just the first time). The scope bar doesn't interfere with touch events upon initial display of the view controller. And there are no visual glitches no matter what the horizontal size class is on an iPad. I really hope the UIKit team can get these resolved before iOS/iPadOS 26 GM.
