In a SwiftUI DocumentGroup, the "Create Document" button remains permanently disabled when attempting to open a document that is in a conflict state (e.g., due to simultaneous edits across devices). As a result, the user cannot create new documents, and the app becomes stuck. On macOS, the expected conflict resolution dialog appears, and the app continues to function normally. On iOS, however, the "Create Document" button stays disabled indefinitely. This behavior occurs consistently in a default SwiftUI document-based app. Steps to Reproduce: Create a new SwiftUI document-based project in Xcode; Setup iCloud Storage in Signing & Capabilities; Create an empty document and place it in a conflict state (e.g., save it simultaneously from two devices); Attempt to open the conflicted document on an iPhone or iPad; Expected Result: The user should be able to resolve the conflict and continue working; The "Create Document" button should remain functional; Actual Result: The "Create Document" button is disabled permanently; The app cannot create new documents until restarted; Environment; iOS 18, iOS 26 (latest tested); Xcode Version 16.4 (16F6) Reproduced on iPhone and iPad; Works as expected on macOS; This appears to be a blocking issue in SwiftUI’s DocumentGroup on iOS.

Hi, I hope you are doing well. We have been running up against an issue in our application which despite our best efforts we cannot seem to solve. After a certain point of use (of which we cannot seem to isolate a trigger), something internally with the way SwiftUI handles animation transactions seems to be breaking. This results in the following behavior that we (and our users) are noticing: Alerts/Sheets/NavigationPath changes lose all animations Closures associated with buttons no longer fire at all. The alert disappears, but with no animation and any action associated with the button selected does nothing. This results in an infinite loop of triggering an alert, clicking on an alert action, and the alert dismissing without the corresponding action ever occurring. We have tried moving the navigationPath out of a view model (Observable) and into a @State variable on the view in case it was an issue with view pre-rendering due to path changes, but this did not improve our case. We hoisted the state and the alert presentation out of all subviews and onto the root view of our navigation destination (as this happens on a sub-page of the application) as well, and while did this seem to minimize occurrences it did not fully resolve it. The app structure of our watch app is as follows: We have a NavigationStack at the root level which wraps a TabView, containing 3 pages. Selecting a button triggers a navigation destination, presenting a detail view. The detail view is a ZStack which switches on a property contained in an @State Observable view model scoped to the detail view. The ZStack can contain one of 5 subviews, derived from a viewState enum with associated values (all of which are equatable, and by extension viewState is also an equatable type as well). One of the subviews receives a binding, which on button trigger updates the binding and thus the view containing the ZStack presents the alert. Sometimes, when this happens, the animations break, and then are subsequently broken for the remainder of the lifetime of the app until it is force-closed (not backgrounded, but a full force-close). NavigationStack { TabView { Tab1 Tab2 // triggers navigationDestination Tab3 } .navigationDestination(for:) { DestinationView() // the view containing the ZStack + Alert } } STEPS TO REPRODUCE Unfortunately we have not been able to ascertain exactly what is causing this issue as we cannot reproduce it in a sandbox environment, only when moving through the view flow associated with our code. Any debugging ideas or recommendations would be greatly appreciated, as we have already tried _printChanges and do not notice any erroneous view redraws.

If the NavigationSplitView on iPadOS 26 is combined with a .inspector column, the sidebarToggle is always hidden, when the sidebar is collapsed. If you remove the .inspector modifier, the sidebarToggle stays visible throughout the collapsed or expanded state. Has maybe someone a workaround for this issue? The problem does not exist in iOS 18. The bug is reported as FB20061260

Currently refreshable modifier does not support nil as a value and there's no way of disabling refreshable without recreating the whole view. There are a few posts showing how refreshable could be optionally disabled on scrollViews using: \EnvironmentValues.refresh as? WritableKeyPath<EnvironmentValues, RefreshAction?> https://stackoverflow.com/a/77587703 However, this approach doesn't seem to work with Lists. Has anyone find any solutions for this?

[Also submitted as FB20262774. Posting here in hopes of saving someone else from burning half a day chasing this down.] Dynamic scaling of an Image() in a Button(), incorrectly decreases when transitioning from XXX Large to AX 1 accessibility text sizes, instead of continuing to grow as expected.

Hi, I am currently developing a document-based application for macOS and have encountered a challenge related to document container management. Specifically, I need to open a windowGroup that shares the same container as the one used in the DocumentGroup. However, my current approach of using a global shared model container has led to unintended behavior: any new document created is linked to existing ones, and changes made in one document are reflected across all documents. To address this issue, I am looking for a solution that allows each newly created document to be individualized while still sharing the document container with all relevant WindowGroups that require access to the data it holds. I would greatly appreciate any insights or recommendations you might have on how to achieve this. Thank you for your time and assistance. Best regards, Something like: @main struct Todo: App { var body: some Scene { DocumentGroup(editing: Item.self, contentType: .item) { ContentView() } WindowGroup { UndockView() .modelContainer(of documentGroup above) } } }

I want to check if this behaviour is legit in iOS 26 Beta: We have an admittedly stranger setup where a child view controller acts as a TabBar and is a UIHostingController so that we can use SwiftUI for the tab bar items. One of the tab pages has a scrollview whose content (imagine a chat view) might go from a lighter aspect to darker colors and back when scrolling. When we scroll to predominantly dark bubbles, the trait of the tabBar changes to dark mode. The function traitCollectionDidChange() on the UIHostingController is called ! but only for the tabBar controller. I know that in iOS there is some blending going on at the tabBar level when scrolling, but changing just one view + subviews to dark mode, automatically, instead of user triggered? It might be some optimisation if the view is considered opaque? But then I would expect to not change anything visually, if opaque. Is this expected behaviour on iOS 26? And if so, can we disable it? But just this blending/ trait changing, and keep the user triggered trait changes.

Can the SwiftUI document architecture Take a file as read-only; never to be written out Take files too large for memory (multi-MB, or even GB) I wouldn't want the system to read a gigabyte size file into memory by default. If the system can use a memory-mapped Data as the representation, that'll be something I can make do. It would be even better if I could tell the system that I'll handle all the reading, all I need from it is a reference to the file's location on disk.

In my own fairly complex DocumentGroup app, I've been having a problem with bottom bar items appearing briefly when first drawn, and then disappearing. This seems to be caused by the invalidation of one or more views in the hierarchy. In Apple's own WritingApp, which is designed to demonstrate DocumentGroup, adding a bottom bar item to the toolbar demonstrates the problem: This toolbar is on the StoryView: ToolbarItem() { Button("Show Story", systemImage: "book") { isShowingSheet.toggle() } .sheet(isPresented: $isShowingSheet) { StorySheet(story: document.story, isShowingSheet: $isShowingSheet) .presentationSizing(.page) } } // This does not persist ToolbarItem(placement: .bottomBar) { Button("Foo") { } } } My 'Foo' button is new. What happens is that it persists for a few seconds; its disappearance coincides with the writing of the file to disk, it seems. I would dearly like it to persist! I've tried adding an ID, setting the toolbar visibility and so on, but no luck. Anyone had this working?

I'm building a SwiftUI app for iPad using a NavigationSplitView as the navigation root. Below is a simplified version of the app's navigation. There are a Home Page and a Settings Page, each with its own NavigationStack. The page that appears in the detail column depends on the sidebar's selection value. The issue I'm facing is that when I navigate deeply into the Home Page's NavigationStack (e.g., to a Home Page Child view), switch to the Settings Page, and then switch back to the Home Page, the Home Page's navigation path has been reset to [] and the previous state is lost. The same issue occurs if I navigate deeply into the Settings Page (e.g., to a Settings Page Child view), switch to the Home Page, and then return to the Settings Page: the navigation state for the Settings Page is lost, and it reverts to the root of the NavigationStack. Why is this happening and how can I fix it so that switching pages in the sidebar doesn't reset the NavigationStack of each individual page in the detail column? Thank you. struct ContentView: View { @State var selection: String? @State var firstPath = [String]() @State var secondPath = [String]() var body: some View { NavigationSplitView { List(selection: $selection) { Text("Home") .tag("home") Text("Settings") .tag("settings") } } detail: { if selection == "home" { HomePage(path: $firstPath) } else { SettingsPage(path: $secondPath) } } } } struct HomePage: View { @Binding var path: [String] var body: some View { NavigationStack(path: $path) { NavigationLink("Home Page", value: "Home") .navigationDestination(for: String.self) { _ in Text("Home Page Child") } } } } struct SettingsPage: View { @Binding var path: [String] var body: some View { NavigationStack(path: $path) { NavigationLink("Settings Page", value: "Settings") .navigationDestination(for: String.self) { _ in Text("Settings Page Child") } } } } #Preview { ContentView() }

Hello Apple forum ! I spotted a weird behaviour with LazyVStack in a ScrollView. I understand that it loads its views only once upon appearance unlinke VStack that loads everything in one shot. What I noticed also, it seems to reload its views sometimes when scrolling back up to earlier loaded views. The thing is, it isn't always the case. struct LazyVStackTest: View { var body: some View { ScrollView { LazyVStack { ForEach(0..<1000, id: \.self) { _ in // if true { MyText() // } } } } } struct MyText: View { var body: some View { let _ = Self._printChanges() HStack { Text("hello") } } } } If we consider the code above on XCode 26 beta 7 on an iOS 26 or iOS 18.2 simulator. Scroll to the bottom : you'll see one "LazyVStackTest.MyText: @self changed" for each row. Then scroll back up to the top, we'll see again the same message printed multiple times. --> So I gather from this that LazyVStack not only loads lazily but also removes old rows from memory & recreates them upon reappearance. What I don't get however is that if you uncomment the "if true" statement, you won't see the reloading happening. And I have absolutely no clue as to why 😅 If someone could help shed some light on this weird behaviour, it would be greatly appreciated ^^ PS : the issue is also present with XCode 16.2 but at a deeper lever (ex: if we embed another custom View "MyText2" inside "MyText", the reloading is in "MyText2" & not "MyText")

Hi, i'm using the PasteButton component to paste content from clipboard. On the docs it says that the PasteButton will handle internally permissions and will not present the prompt. But in my case seems to be not true. I removed all the occurrencies of UIPasteboard.general.string since i read that this will cause the prompt to appear. Also as you can see on the code below i'm not doing fancy or weird things, even with the base component this behaviour is still there. PasteButton(payloadType: String.self) { strings in if let first = strings.first { print("clipboard text: \(first)") } } I can see other apps using this paste button without asking for permissions every time, but i cannot see any issue in my code.

Hi, I have trouble changing the color of the text of Link in SwiftUI. I tried with this code: Link("https://www.mylink.com/", destination: URL(string: "https://www.mylink.com/")!) .foregroundColor(Color.green) and this code: HStack(spacing: 0) { Link("https://www.mylink.com/", destination: URL(string: "https://www.mylink.com/")!) } .foregroundColor(Color.green) The link keeps getting the accent color. EDIT: I want to add that it used to work and I think the issue came with a beta of Xcode 26. I think that was around the beta 4 or beta 5. Is it a change of the APIs or a bug?

Hi! How can I create a toolbar animation in SwiftUI like the one shown at 16:54 in WWDC session?

I have an app using TabView with multiple Tabs using tabViewStyle „sidebarAdaptable“. Each Tab does have its own NavigationStack. When I switch multiple times between the tabs and append a child view to one of my navigation stacks, it will stop working after a few tries with the following error „A NavigationLink is presenting a value of type “HomeStack” but there is no matching navigationDestination declaration visible from the location of the link. The link cannot be activated. Note: Links search for destinations in any surrounding NavigationStack, then within the same column of a NavigationSplitView.“ The same code is working fine on iOS, iPadOS but not working on macOS. When I remove tabViewStyle of sidebarAdaptable it’s also working on macOS. I shrinked it down to a minimal reproducible code sample. Any idea if that is a bug or I'm doing something wrong? struct ContentView: View { @State private var appState: AppState = .init() var body: some View { TabView(selection: $appState.rootTab) { Tab("Home", systemImage: "house", value: RootTab.home) { NavigationStack(path: $appState.homeStack) { Text("Home Stack") NavigationLink("Item 1", value: HomeStack.item1) .padding() NavigationLink("Item 2", value: HomeStack.item2) .padding() .navigationDestination(for: HomeStack.self) { stack in Text("Stack \(stack.rawValue)") } .navigationTitle("HomeStack") } } Tab("Tab1", systemImage: "gear", value: RootTab.tab1) { NavigationStack(path: $appState.tab1Stack) { Text("Tab 1 Stack") NavigationLink("Item 1", value: Tab1Stack.item1) .padding() NavigationLink("Item 2", value: Tab1Stack.item2) .padding() .navigationDestination(for: Tab1Stack.self) { stack in Text("Stack \(stack.rawValue)") } .navigationTitle("Tab1Stack") } } } .tabViewStyle(.sidebarAdaptable) .onChange(of: appState.rootTab) { _, _ in appState.homeStack.removeAll() appState.tab1Stack.removeAll() } } } @MainActor @Observable class AppState { var rootTab: RootTab = .home var homeStack: [HomeStack] = [] var tab1Stack: [Tab1Stack] = [] } enum RootTab: Hashable { case home case tab1 case tab2 } enum HomeStack: String, Hashable { case home case item1 case item2 } enum Tab1Stack: String, Hashable { case home case item1 case item2 }

I have a popover/sheet in iOS which allows users to search and add items to a list. When the sheet is shown, the search should always be active. I am using searchable on a NavigationStack inside the sheet. I am using the isPresented parameter to activate search. My issue is with the animation of the search activation. Even if I use... isPresented: .constant(true) ...the search isn't activated until the sheet has completed it's entrance animation, resulting in two stages of animation. I can't add a video here, but the two images below show the steps I am seeing. First a slide up animation, with the search in the navigation drawer, then a second animation, once the sheet is fully in place, as the search becomes active. Is it possible to merge these two animations, so search is in place when the sheet animates up?

In SwiftUI for macOS, when implementing a DragGesture inside a ScrollVIew, how can I implement auto-scrolling when the mouse is not actively moving? In AppKit, this would normally be done with a periodic event so that auto-scrolling continues to take place even if the user isn't actively moving the mouse. This is essential behaviour when implementing something like a drag-to-select gesture. NSView.autoscroll(with: NSEvent) -> Bool Is there anything in SwiftUI or ScrollView to accomplish this behaviour?
