Hey, I am building some widgets and I'm quite surprised that Swipe gestures for widgets is not supported. It means the user must sacrifice home screen real estate to view multiple widgets to receive the same information. Ideally, swiping left / right inside of the widget should give a developer access to present different views. I realize that it means that a user would need to swipe outside of the widget, (or swipe to the beginning/end of the series of views inside of the widget) for the page to swipe, but I'd argue that this is the intuitive behavior of what widget scrollview would or should look like anyway.

Hello, since I'm using SwiftUI and some interface should be optimized for different devices(like iPad and iPhone), so I'm curious that what device would be used to run the App? Is it iPad or iPhone? And could I use SDKs like SiriKit?

NavigationTitle does not change when the app language changes. It works well in iOS 17.5 but does not in iOS 18.x

Our app presents an NSOpenPanel with an accessory view implemented in SwiftUI and presented via NSHostingView. TextFields and pickers are working OK, but Buttons and Toggles (checkboxes) aren’t, although Toggles styled with .switch are functioning as expected. Specifically: Toggles styled with .checkbox fail with no feedback. Overriding NSHostingView mouseDown() shows that the mouse event is completely ignored by the Toggle Buttons “see” the mouseDown event (the button highlights when pressed, and the event doesn’t fall through to the hosting view), but the button action isn’t triggered until the dialog is dismissed Any idea on how to get these controls functional?

In our app clip, we open/show the full app download banner. We used to have the expected behavior, but with seemingly no changes to the app download banner code we have the following issue. Expected behavior: App download banner shows in app clip, user presses "Get" button, app is downloaded and installs, "Get" button changes to "Open" button (note: button is blue), user presses "Open" button and the full app is opened. Current behavior: App download banner shows in app clip, user presses "Get" button, app is downloaded and installs, "Get" button changes to "Open" button (note: button is now grey), user presses "Open" button but nothing happens. With the current behavior, the full app is correctly downloaded and the appclip removes itself from the phone, but the open button does nothing.

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) -> 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 <key>UIApplicationSceneManifest</key> <dict> <key>UIApplicationSupportsMultipleScenes</key> <true/> <key>UISceneConfigurations</key> <dict> <key>UIWindowSceneSessionRoleApplication</key> <array> <dict> <key>UISceneConfigurationName</key> <string>Default Configuration</string> <key>UISceneDelegateClassName</key> <string>Presentation.SceneDelegate</string> </dict> </array> </dict> </dict> // In the AppDelegate public func application(_ application: UIApplication, configurationForConnecting connectingSceneSession: UISceneSession, options: UIScene.ConnectionOptions) -> 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?

I am revising my app to support NSWritingToolsCoordinator/ NSWritingToolsCoordinatorDelegate. When proofreading some paragraphs, it works well. But, when proofreading many paragraphs (for example, 56 paragraphs), it can't complete the proofreading. I am not sure which is wrong with my app or macOS API. I think I implemented all NSWritingToolsCoordinatorDelegate methods. Is there any information for such an issue? Phenomenon For paragraphs 1-9, text animation completed. But, for paragraphs 10-56, text animation does not complete. It shows 5 corrected items, but I can't jump to items 3, 4, 5, when I click the ">" button in the "Proofread" window. Items 3, 4, 5 were not corrected actually. Log For each NSWritingToolsCoordinatorDelegate method, the method name and main arguments are output by NSLog. requestsContextsForScope willChangeToState newState:2 requestsPreviewForTextAnimation range:(0, 18233) prepareForTextAnimation range:(0, 18233) willChangeToState newState:3 requestsPreviewForTextAnimation range:(0, 18233) finishTextAnimation range:(0, 18233) requestsPreviewForRect requestsPreviewForTextAnimation range:(0, 1837) replaceRange proposedText:an range:(208, 2) replaceRange proposedText:you range:(443, 4) prepareForTextAnimation range:(1836, 16396) requestsPreviewForTextAnimation range:(0, 1836) requestsBoundingBezierPathsForRange range:(208, 2) requestsBoundingBezierPathsForRange range:(443, 3) requestsPreviewForRect prepareForTextAnimation range:(0, 1836) prepareForTextAnimation range:(1836, 0) finishTextAnimation range:(1836, 16396) requestsPreviewForTextAnimation range:(1836, 16396) requestsBoundingBezierPathsForRange range:(208, 2) requestsBoundingBezierPathsForRange range:(443, 3) prepareForTextAnimation range:(1836, 16396) finishTextAnimation range:(0, 1836) finishTextAnimation range:(0, 1836) replaceRange proposedText:an range:(208, 2) requestsUnderlinePathsForRange range:(208, 2) requestsUnderlinePathsForRange range:(443, 3) selectRanges ranges.count:1 requestsBoundingBezierPathsForRange range:(208, 2) replaceRange proposedText:an range:(208, 2) requestsUnderlinePathsForRange range:(208, 2) requestsUnderlinePathsForRange range:(443, 3) selectRanges ranges.count:1 replaceRange proposedText:you range:(443, 3) requestsUnderlinePathsForRange range:(208, 2) requestsUnderlinePathsForRange range:(443, 3) selectRanges ranges.count:1 requestsBoundingBezierPathsForRange range:(443, 3) replaceRange proposedText:you range:(443, 3) requestsUnderlinePathsForRange range:(208, 2) requestsUnderlinePathsForRange range:(443, 3) selectRanges ranges.count:1 macOS version is 15.3.1 (24D70)

I have a small example app which uses a context menu to open an editor view. The screenshot below is from Xcodes Preview. When I run the application the Table is not rendered. See below: The code can be downloaded from Github/TableBug

I’m trying to implement my Examples view in my DocumentGroup app on visionOS. I am stuck on what on the surface seems very basic: programmatically opening a document. Is there an analog to NSDocumentController.shared.openUntitledDocumentAndDisplay on visionOS? Here’s what I’ve tried so far. Ideally, this would a be collection of document templates in a DocumentGroupLaunchScene. However, I’ve been unable to get DocumentGroupLaunchScene to work on visionOS. I’ve tried UIApplication.shared.open(url) with a url to a document in my app bundle. UIApplication.shared.canOpenURL(url) returns true, but open(url) has no effect. In the macOS build, I use NSDocumentController.shared.openUntitledDocumentAndDisplay, but do not see any iOS or visionOS analog. @Environment(\.newDocument) private var newDocument would be ideal, but that is not available on visionOS. UIApplication.shared.activateSceneSession(for: .init()) brings up the document browser in a new window, at which point clicking the “+” button does what I want. Can I invoke that directly somehow? It would be sufficient if I could programmatically open a new untitled document. On macOS, I do that and sneak the template contents to the Document constructor in a global variable. I presume I am just overlooking something simple, but I’ve come up blank so far.

In macOS application, we are using SwiftUI as an entry point to our application and attaching appdelegate using NSApplicationDelegateAdaptor. We are using NSViewControllerRepresentable to add a View Controller to the hiracrchy so that we can store intance of viewcontroller and add content to it programatically . @main struct TWMainApp: App { @NSApplicationDelegateAdaptor private var appDelegate: TWAppDelegate internal var body : some Scene { TWInitialScene () } } TWInitialScene : public struct TWInitialScene : Scene { public var body : some Scene { WindowGroup { TWInitialView () } } } TWInitialView : struct TWInitialView : View { @Environment(\.scenePhase) private var scenePhase var body : some View { TWAppKitToSwiftUIBridge () } } TWAppKitToSwiftUIBridge : struct TWNSKitToSwiftUIBridge : NSViewControllerRepresentable { func makeNSViewController(context: Context) -> TWNSViewController { let view_hierarchy : TWNSViewController view_hierarchy = TWStaticContext.sViewController return view_hierarchy } func updateNSViewController(_ nsViewController: TWNSViewController, context: Context) { } } @objc public class TWStaticContext : NSObject { public static let sViewController = TWNSViewController () public override init () {} @objc public static func GetViewController () -> TWNSViewController { return TWStaticContext.sViewController } } public class TWNSViewController : NSViewController { override public func viewDidLoad () { super.viewDidLoad () } } To add content to the hirarchy we are accessing viewcontroller's intance and adding content to it like this : public func PaintInitialScreen () { let label = NSTextField(labelWithString: "TW window") label.frame = NSRect(x: 100, y: 200, width: 200, height: 200) // Adding content to viewcontroller TWStaticContext.sViewController.view.addSubview(label) } We are using this approach because we have a contraint in our application that we have to update UI programatically and on compile time we dont know what we want to show . We will be adding content on runtime based on how many button we want, what label we want , where to place it etc. When we were using purely appKit application, doing things programatically was simple but since SwiftUI is a declarative application we have to use above approach. Rational for shifting to SwiftUI entry point is that we want our application to be future safe and since apple is more inclined to SwiffUI, we want to design our entry flow to use SwiftUI entry point . And SwiftUI being declarative, we are using appKit to add content to hiracrchy programtically. We have used similar apprach in iOS also , where are using UIApplicationDelegateAdaptor inplace of NSApplicationAdaptor . And UIViewControllerReprestable in place of NSViewControllerRepresentable. Is this right approach to use ?

Hey everyone! Totally a newbe question here but cant find the answer anywhere when searching so figured I would just post. Trying to create my first SwiftUI app in Xcode and wanted to create a simple launch screen with an image file, and a text label. however when I select the launch screen in the Project settings it lets me pick it, but then when i navigate away it never saves the value. Then when I go somewhere else and come back its blank again... Any thoughts? XCode 16.2

I'm looking to develop a very rich networking macOS app (like social media apps) operated by very large number of users, each user is able to create a number of windows, operate/view each of them, able to customize the app to his liking etc. The UI is expected to be very rich and dynamic. The question is, should I choose AppKit or SwiftUI? I have a basic understanding of SwiftUI, its declarative way of defining UI layouts and populating it with data. Not sure if SwiftUI can handle a very rich and dynamic UI customised by large number of users. Any thoughts? What works best in this scenario? What is Apple's recommendation?

Hi, I have created a line graph using LineMark in Charts, which by default includes grid lines and axes lines. My requirement is to remove the grid lines but retain the axes lines and the values. I have tried the following code: .chartXAxis { AxisMarks(preset: .extended, values: .stride(by: 2), stroke: StrokeStyle(lineWidth: 0)) } This is removing grid lines as well as axes lines. How to retain axes lines while removing grid lines ?

I am considering of shifting my codebase from appkit to SwiftUI entry point. In Appkit, we get control on each NSWindow. So that we can hide/resize window, close window and controll when to present a specific window . Because i have access to NSWindow instance which i can store and perform these actions. But when i shift to SwiftUI entry point, i declare struct conforming to SwiftUI Scene. And new windows will be created with the instance of this scene. I am using NSViewControllerRepresentable to add a NSViewController to the hierarchy of these scene. And adding content to this NSViewController's instance to show on screen. I need help in controlling the size of these windows. How can i close specific window ? Resize specific window ? or Hide specific window? If i use purely SwiftUI view's , then i can do this by using the Enviorment propery and use DismissWindow to close a window or openWindow with identifier to open a specific window by passing the specificer . But i am using Appkit's NSViewController where i will add buttons in heirarchy from which i want to trigger these events . And in that case how can i controll a specific window in case of multiwindow application?

I want to present a textfield inside a sheet. However when the keyboard is shown, the sheet view produces extra padding even though I explicitly set the frame of the textfield and the presentationDent to be the exact same height. Reproducible example: struct ContentView: View { @State var showSheet: Bool = false @State var text = "" var body: some View { VStack { Image(systemName: "globe") .imageScale(.large) .foregroundStyle(.tint) Text("Hello, world!") Button { showSheet.toggle() } label: { Text("Show Sheet") } } .sheet(isPresented: $showSheet) { TextField("Hello", text: $text) .frame(height: 44) .background(.red) .presentationDetents([.height(44)]) .presentationDragIndicator(.hidden) } } } Does anyone know how to resolve this issue?

In one of my applications I use several List views with Sections. After upgrading to Sequoia I faced the issue, that after selecting an item, the List suddenly scrolls to a different position. Sometimes the selection even gets out of the view, but in every case a double click just went to the wrong item. At one list I found out, that the issue could be solved after changing the data source. I used a computed property, what seems to be a stupid idea. After changing this it now works. Unfortunately there is another List, where this didn't bring the solution. And unfortunately, I cannot reproduce the issue in a code example. One guess of mine is, that it could be related to the fact, that the rows have different heights (because in some are two lines of text and in some are three). And it seems to happen only in very long lists. It worked perfectly in Sonoma. Does anyone face the same issue?

Hi, A class initialized as the initial value of an @State property is not released until the whole View disappears. Every subsequent instance deinitializes properly. Am I missing something, or is this a known issue? struct ContentView: View { // 1 - init first SimpleClass instance @State var simpleClass: SimpleClass? = SimpleClass(name: "First") var body: some View { VStack { Text("Hello, world!") } .task { try? await Task.sleep(for: .seconds(2)) // 2 - init second SimpleClass instance and set as new @State // "First" should deinit simpleClass = SimpleClass(name: "Second") // 3 - "Second" deinit just fine simpleClass = nil } } } class SimpleClass { let name: String init(name: String) { print("init: \(name)") self.name = name } deinit { print("deinit: \(name)") } } output: init: First init: Second deinit: Second Thanks

I would like to report a memory leak issue in watchOS 11.2 that occurs when using .navigationTitle() inside a sheet. This behavior is reproducible both on the simulator and on a real device, but not on iOS. While this does not register as a leak in Instruments, the deinit of the DetailsViewModel is never called, and multiple instances of the view model accumulate in the Memory Graph Debugger. Commenting out .navigationTitle("Sheet View") resolves the issue, and deinit prints as expected. Using @MainActor on the DetailsViewModel does not fix the issue. Nor does switching to @StateObject and using ObservableObject resolve the memory retention. This issue seems related to other SwiftUI memory leaks that have been reported: https://developer.apple.com/forums/thread/738840 https://developer.apple.com/forums/thread/736110?login=true&page=1#769898022 https://developer.apple.com/forums/thread/737967?answerId=767599022#767599022 Feedback Number: FB16442048 struct MainView: View { var body: some View { NavigationStack { NavigationLink("Details", value: 1) .navigationDestination(for: Int.self) { _ in DetailsView() } } } } struct SheetObject: Identifiable { let id = UUID() let date: Date let value: Int } @Observable @MainActor final class DetailsViewModel { var sheetObject: SheetObject? init() { print("Init") } deinit { print("Deinit") } func onAppear() async { try? await Task.sleep(for: .seconds(2)) sheetObject = .init(date: .now, value: 1) } } struct DetailsView: View { @State private var viewModel = DetailsViewModel() @Environment(\.dismiss) var dismiss var body: some View { Text("Detail View. Going to sheet, please wait...") .task { await viewModel.onAppear() } .sheet(item: $viewModel.sheetObject) { sheetObject in SheetView(sheetObject: sheetObject) .onDisappear { dismiss() } } } } struct SheetView: View { let sheetObject: SheetObject @Environment(\.dismiss) var dismiss var body: some View { NavigationStack { VStack { Text(sheetObject.date.formatted()) Text(sheetObject.value.formatted()) Button("Dismiss") { dismiss() } } .navigationTitle("Sheet View") // This line causes a memory leak. Commenting out, you will see "Deinit" be printed. } } }

I found an issue when implementing an alert with a TextField to input a name. I want the action button to be disabled until a name has been entered, but the action block is never executed when the button has become enabled and pressed. The problem seems to appear only when name is initially an empty string. Tested with iOS 17.0. struct MyView: View { @State private var name = "" var body: some View { SomeView() .alert(...) { TextField("Name", text: $name) Button("Action") { // Action }.disabled(name.isEmpty) Button("Cancel", role: .cancel) {} } } }

I want to add a tool bar (setting search )to my app just like the apple file app using pure swiftUI, is it possible, if not, can i using a UIKit to implement it. struct MainView: View { var body: some View { TabView { Tab("View 1", systemImage: "square.grid.3x2") { View1() } Tab("View 2", systemImage: "square.grid.2x2") { View2() } } .tabViewStyle(.sidebarAdaptable) }
