I have a SwiftUI-based universal app which creates a file that it stores in documentsDirectory. On iOS/iPadOS, this file is stored in the application's Documents directory and is accessible via the Files app. On MacCatalyst, this operation does the same thing — it creates the file and stores it in ~/Library/Containers/<app directory>/Data/Documents. However what I want is for the document to be stored in ~/Documents, so that it is easily accessible to the user. How can I do that? I'd like it to occur without (for example) having to show a SaveFile panel...

I’m trying to understand how SwiftUI List handles row lifecycle and reuse during scrolling. I have a list with around 60 card views; on initial load, only about 7 rows are created, but after scrolling to the bottom all rows appear to be created, and when scrolling back to the top I again observe multiple updates and apparent re-creation of rows. I confirmed this behavior using Instruments by profiling my app. Even though each row has a stable identifier, the row views still seem to be destroyed and recreated, which doesn’t resemble UIKit’s cell reuse model. I’d like clarity on how List uses identifiers internally, what actually gets reused versus recreated, and how developers should reason about performance and view lifetime in this case.

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?

I'm being faced with an issue when using SwiftUI's WebView on iOS 26. In many websites, the top/bottom content is unaccessible due to being under the app's toolbars. It feels like the WebView doesn't really understand the safe areas where it's being shown, because the content should start right below the navigation bar, and only when the user scrolls down, the content should move under the bar (but it's always reachable if the users scroll back up). Here's a demo of the issue: Here's a 'fix' by ensuring that the content of the WebView never leaves its bounds. But as you can see, it feels out of place on iOS 26 (would be fine on previous OS versions if you had a fully opaque toolbar): Code: struct ContentView: View { var body: some View { NavigationStack { WebView(url: URL(string: "https://apple.com")).toolbar { ToolbarItem(placement: .primaryAction) { Button("Top content covered, unaccessible.") {} } } } } } Does anyone know if there's a way to fix it using some sort of view modifier combination or it's just broken as-is?

When displaying a view with a Button inside a ScrollView using the sheet modifier, if you try to close the sheet by swiping and your finger is touching the Button, the touch is not canceled. This issue occurs when building with Xcode 16 but does not occur when building with Xcode 15. Here is screen cast. https://drive.google.com/file/d/1GaOjggWxvjDY38My4JEl-URyik928iBT/view?usp=sharing Code struct ContentView: View { @State var isModalPresented: Bool = false var body: some View { ScrollView { Button { debugPrint("Hello") isModalPresented.toggle() } label: { Text("Hello") .frame(height: 44) } Button { debugPrint("World") } label: { Text("World") .frame(height: 44) } Text("Hoge") .frame(height: 44) .contentShape(Rectangle()) .onTapGesture { debugPrint("Hoge") } } .sheet(isPresented: $isModalPresented) { ContentView() } } }

We have an UIViewController called InfoPlayerViewController. Its main subview is from a child view controller backed by SwiftUI via UIHostingController. The InfoPlayerViewController conforms to UIViewControllerTransitioningDelegate. The animation controller for dismissing is DismissPlayerAnimationController. It runs UIKit keyframe animations via UIViewPropertyAnimator. When the keyframe animation is executed there’s an occasional crash for end users in production. It only happens on iOS 26. FB Radar: FB20871547 An example crash is below.

Hello, Is it possible to integrate a database into Swift Playground on iPad? Otherwise, what can be done? Thank you.

I was looking through: https://developer.apple.com/library/archive/documentation/Cocoa/Conceptual/ScriptableCocoaApplications/SApps_handle_AEs/SAppsHandleAEs.html And wondered how these are handled for SwiftUI apps. What would I add or override?

Code example: // // ListSafeAreaBarKeyboardTextField.swift // Exploration import SwiftUI import Foundation struct ListSafeAreaBarKeyboardTextField: View { @State private var typedText: String = "" @FocusState private var focusingTextField: Bool private let items = Array(1...16) var body: some View { ScrollViewReader { proxy in List(items, id: \.self) { number in Text("Item \(number)") .id(number) } .onAppear { if let lastItem = items.last { proxy.scrollTo(lastItem, anchor: .bottom) } } .onChange(of: focusingTextField) { oldValue, newValue in // This simply won't work // ~ 12th - 16th item will still get covered by keyboard if newValue == true { // Delay to allow keyboard animation to complete DispatchQueue.main.asyncAfter(deadline: .now() + 0.3) { if let lastItem = items.last { withAnimation { proxy.scrollTo(lastItem, anchor: .top) } } } } } } .scrollDismissesKeyboard(.interactively) .safeAreaBar(edge: .bottom) { TextField("Type here", text: $typedText, axis: .vertical) .focused($focusingTextField) // Design .padding(.horizontal, 16) .padding(.vertical, 10) .glassEffect() // Paddings .padding(.horizontal, 24) .padding(.vertical, 12) } } }

How do I set a custom icon for an app control that appears in Control Shortcuts (swipe down from iOS) ? Where is the documentation for size and where to put the image, format etc? Thank you. Working Code (sfsymbol) import Foundation import AppIntents import SwiftUI import WidgetKit // MARK: - Open App Control @available(iOS 18.0, *) struct OpenAppControl: ControlWidget { let kind: String = "OpenAppControl" var body: some ControlWidgetConfiguration { StaticControlConfiguration(kind: kind, content: { ControlWidgetButton(action: OpenAppIntent()) { Label("Open The App", systemImage: "clock.fill") } } }) .displayName("Open The App") // This appears in the shortcuts view } } Sample Image These apps use their own image. How can I use my own image?

SwiftUI's colorScheme modifier is said to be deprecated in favour of preferredColorScheme but the two work differently. See the below sample app, colorScheme changes the underlying view colour while preferredColorScheme doesn't. Is that a bug of preferredColorScheme? import SwiftUI struct ContentView: View { let color = Color(light: .red, dark: .green) var body: some View { VStack { HStack { color.colorScheme(.light) color.colorScheme(.dark) } HStack { color.preferredColorScheme(.light) color.preferredColorScheme(.dark) } } } } #Preview { ContentView() } @main struct TheApp: App { var body: some Scene { WindowGroup { ContentView() } } } extension UIColor { convenience init(light: UIColor, dark: UIColor) { self.init { v in switch v.userInterfaceStyle { case .light: light case .dark: dark case .unspecified: fatalError() @unknown default: fatalError() } } } } extension Color { init(light: Color, dark: Color) { self.init(UIColor(light: UIColor(light), dark: UIColor(dark))) } }

Hello, I am experiencing a layout glitch when using the new .navigationTransition(.zoom) in SwiftUI on iOS 18+. While the primary content transitions smoothly, the Navigation Bar elements (Title and ToolbarItems) of the source view exhibit an unwanted horizontal sliding animation during the transition. The Problem: As the zoom transition begins, the large inline title and the trailing toolbar buttons do not simply fade out or stay pinned. Instead, they slide to the left of the screen and when destination view is closed they slide back to their place. This creates a "janky" visual effect where the navigation bar appears to collapse or shift its coordinate space while the destination view is expanding. Problem video link:-

I’m seeing unexpected scroll behavior when embedding a LazyVStack with dynamically sized views inside a ScrollView. Everything works fine when the item height is fixed (e.g. colored squares), but when I switch to text views with variable height, the scroll position jumps and glitches—especially when the keyboard appears or disappears. This only happens on iOS 26, it works fine on iOS 18. Working version struct Model: Identifiable { let id = UUID() } struct ModernScrollView: View { @State private var models: [Model] = [] @State private var scrollPositionID: String? @State private var text: String = "" @FocusState private var isFocused // MARK: - View var body: some View { scrollView .safeAreaInset(edge: .bottom) { controls } .task { reset() } } // MARK: - Subviews private var scrollView: some View { ScrollView { LazyVStack { ForEach(models) { model in SquareView(color: Color(from: model.id)) .id(model.id.uuidString) } } .scrollTargetLayout() } .scrollPosition(id: $scrollPositionID) .scrollDismissesKeyboard(.interactively) .defaultScrollAnchor(.bottom) .onTapGesture { isFocused = false } } private var controls: some View { VStack { HStack { Button("Add to top") { models.insert(contentsOf: makeModels(3), at: 0) } Button("Add to bottom") { models.append(contentsOf: makeModels(3)) } Button("Reset") { reset() } } HStack { Button { scrollPositionID = models.first?.id.uuidString } label: { Image(systemName: "arrow.up") } Button { scrollPositionID = models.last?.id.uuidString } label: { Image(systemName: "arrow.down") } } TextField("Input", text: $text) .padding() .background(.ultraThinMaterial, in: .capsule) .focused($isFocused) .padding(.horizontal) } .padding(.vertical) .buttonStyle(.bordered) .background(.regularMaterial) } // MARK: - Private private func makeModels(_ count: Int) -> [Model] { (0..<count).map { _ in Model() } } private func reset() { models = makeModels(3) } } // MARK: - Color+UUID private extension Color { init(from uuid: UUID) { let hash = uuid.uuidString.hashValue let r = Double((hash & 0xFF0000) >> 16) / 255.0 let g = Double((hash & 0x00FF00) >> 8) / 255.0 let b = Double(hash & 0x0000FF) / 255.0 self.init(red: abs(r), green: abs(g), blue: abs(b)) } } Not working version When I replace the square view with a text view that generates random multiline text: struct Model: Identifiable { let id = UUID() let text = generateRandomText(range: 1...5) // MARK: - Utils private static func generateRandomText(range: ClosedRange<Int>) -> String { var result = "" for _ in 0..<Int.random(in: range) { if let sentence = sentences.randomElement() { result += sentence } } return result.trimmingCharacters(in: .whitespaces) } private static let sentences = [ "Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.", "Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat.", "Duis aute irure dolor in reprehenderit in voluptate velit esse cillum dolore eu fugiat nulla pariatur.", "Excepteur sint occaecat cupidatat non proident, sunt in culpa qui officia deserunt mollit anim id est laborum." ] } and use it like this: ForEach(models) { model in Text(model.text) .padding() .multilineTextAlignment(.leading) .background(Color(from: model.id)) .id(model.id.uuidString) } Then on iOS 26, opening the keyboard makes the scroll position jump unpredictably. It is more visible if you play with the app, but I could not upload a video here. Environment Xcode 26.0.1 - Simulators and devices on iOS 26.0 - 18.0 Questions Is there any known change in ScrollView / scrollPosition(id:) behavior on iOS 26 related to dynamic height content? Am I missing something in the layout setup that makes this layout unstable with variable-height cells? Is there a workaround or recommended approach for keeping scroll position stable when keyboard appears?

I have found that following code runs without issue from Xcode, either in Debug or Release mode, yet crashes when running from the binary produced by archiving - i.e. what will be sent to the app store. import SwiftUI import AVKit @main struct tcApp: App { var body: some Scene { WindowGroup { VideoPlayer(player: nil) } } } This is the most stripped down code that shows the issue. One can try and point the VideoPlayer at a file and the same issue will occur. I've attached the crash log: Crash log Please note that this was seen with Xcode 26.2 and MacOS 26.2.

I am creating a macOs SwiftUI document based app, and I am struggling with the Window sizes and placements. Right now by default, a normal window has the minimize and full screen options which makes the whole window into full screen mode. However, I don't want to do this for my app. I want to only allow to fill the available width and height, i.e. exclude the status bar and doc when the user press the fill window mode, and also restrict to resize the window beyond a certain point ( which ideally to me is 1200 x 700 because I am developing on macbook air 13.3-inch in which it looks ideal, but resizing it below that makes the entire content inside messed up ). I want something like this below instead of the default full screen green When the user presses the button, it should position centered with perfect aspect ratio from my content ( or the one I want like 1200 x 700 ) and can be able to click again to fill the available width and height excluding the status bar and docs. Here is my entire @main code :- @main struct PhiaApp: App { @NSApplicationDelegateAdaptor(AppDelegate.self) var appDelegate var body: some Scene { DocumentGroup(newDocument: PhiaProjectDocument()) { file in ContentView( document: file.$document, rootURL: file.fileURL ) .configureEditorWindow(disableCapture: true) .background(AppColors.background) .preferredColorScheme(.dark) } .windowStyle(.hiddenTitleBar) .windowToolbarStyle(.unified) .defaultLaunchBehavior(.suppressed) Settings { SettingsView() } } } struct WindowAccessor: NSViewRepresentable { var callback: (NSWindow?) -> Void func makeNSView(context: Context) -> NSView { let view = NSView() DispatchQueue.main.async { [weak view] in callback(view?.window) } return view } func updateNSView(_ nsView: NSView, context: Context) { } } extension View { func configureEditorWindow(disableCapture: Bool = true) -> some View { self.background( WindowAccessor { window in guard let window else { return } if let screen = window.screen ?? NSScreen.main { let visible = screen.visibleFrame window.setFrame(visible, display: true) window.minSize = visible.size } window.isMovable = true window.isMovableByWindowBackground = false window.sharingType = disableCapture ? .captureBlocked : .captureAllowed } ) } } This is a basic setup I did for now, this automatically fills the available width and height on launch, but user can resize and can go beyond my desired min width and height which makes the entire content inside messy. As I said, I want a native way of doing this, respect the content aspect ratio, don't allow to enter full screen mode, only be able to fill the available width and height excluding the status bar and doc, also don't allow to resize below my desired width and height.

Any view that is content for the tabViewBottomAccessory API fails to retain its state as of the last couple of 26.1 betas (and RC). The loss of state happens (at least) when the currently selected tab is switched (filed as FB20901325). Here's code to reproduce the issue: struct ContentView: View { @State private var selectedTab = TabSelection.one enum TabSelection: Hashable { case one, two } var body: some View { TabView(selection: $selectedTab) { Tab("One", systemImage: "1.circle", value: .one) { BugExplanationView() } Tab("Two", systemImage: "2.circle", value: .two) { BugExplanationView() } } .tabViewBottomAccessory { AccessoryView() } } } struct AccessoryView: View { @State private var counter = 0 // This guy's state gets lost (as of iOS 26.1) var body: some View { Stepper("Counter: \(counter)", value: $counter) .padding(.horizontal) } } struct BugExplanationView: View { var body: some View { ScrollView { VStack(alignment: .leading, spacing: 16) { Text("(1) Manipulate the counter state") Text("(2) Then switch tabs") Text("BUG: The counter state gets unexpectedly reset!") } .multilineTextAlignment(.leading) } } }

When tap the Button quickly in List, the ButtonStyleConfiguration’s isPressed property don't change properly, always false. When using Button in ScrollView, the same error doesn't exist.

My app uses SwiftUI Map and draws Markers, MapPolyline and MapPolygons over it. These all work on actual devices. On the iOS 26.0.1 Simulator running on macOS 26.0.1 Polylines and Polygons do now show. Do others see the same thing?

Hello, I am currently in the process of gradually adding support for LiquidGlass to my app. The transition is taking place incrementally, i.e., new screens and minor features are gradually being adapted to the new design and already deployed. Currently, the old design is still active via the feature flag UIDesignRequiresCompatibility, as the existing UI should remain locked for the public app store version until the transition is complete. My challenge is as follows: I would like to work with the new LiquidGlass design during development without having to manually change the UIDesignRequiresCompatibility flag with each deployment. Ideally, I am looking for a solution where: • the new design is only activated for me (e.g., specific account or specific devices) • the old design remains active for all other users • the App Store version can be delivered unchanged So my question is: Is it possible to control UIDesignRequiresCompatibility via remote config or server-side logic in order to activate the new design specifically for certain users or devices? I have observed similar behavior on WhatsApp—two devices with the same app version, but only one shows the new design. This suggests server-side or remote config-based control. Do you have any experience or recommendations on how to implement something like this cleanly? Kind regards Heinz
