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 have an app with two file types with the following extensions: gop (an exported type), sgf (an imported type). The Save command fails after the following sequence of events: I open a gop file, say the file "A.gop". I save this file as an sgf file, say "A.sgf". This Save As works perfectly and the document name in the document’s title bar has changed to "A.sgf". I change something in the document and then try to Save this change. This should just resave the document to "A.sgf", but "A.sgf" remains untouched. Instead I get a system alert with the message The document “A.sgf” could not be saved. A file with the name “A.gop” already exists. To save the file, either provide a different name, or move aside or delete the existing file, and try again. In the Xcode console I get the following diagnostic: NSFileSandboxingRequestRelatedItemExtension: an error was received from pboxd instead of a token. Domain: NSPOSIXErrorDomain, code: 2 [NSFileCoordinator itemAtURL:willMoveToURL:] could not get a sandbox extension. oldURL: file:///Users/francois/Desktop/A.sgf, newURL: file:///Users/francois/Desktop/A.gop The problem seems to relate to the sandbox. But I am at a loss to find a solution. (After closing the alert, I check that A.sgf did not register the change.) If I open an sgf file, say "B.sgf", save it as "B.gop", make a change in the document and then try to save this change (into "B.gop"), I hit the same problem, with "gop" and "sgf" interchanged. If, instead of saving "A.gop" as "A.sgf", I save it as "B.sgf", make a change in the document and then try to save this change into "B.sgf", I get the following system alert: The document “B.sgf” could not be saved. You don’t have permission. To view or change permissions, select the item in the Finder and choose File > Get Info. And in the Xcode console I get the following diagnostic: NSFileSandboxingRequestRelatedItemExtension: an error was received from pboxd instead of a token. Domain: NSPOSIXErrorDomain, code: 2 [NSFileCoordinator itemAtURL:willMoveToURL:] could not get a sandbox extension. oldURL: file:///Users/francois/Desktop/B.sgf, newURL: file:///Users/francois/Desktop/B.gop Again the sandbox ! (After closing the alert, I check that B.sgf did not register the change.) It’s clear my code is missing something, but what?

Hi Team, when launching an ApplePay session from a 3rd party browser where we get the QR code popup - is it possible to affect the popup's language? We are setting the button's language via locale parameter, but when the QR code pop's up it does not respect this setting (seems like it respects browser language). Button in Arabic Corresponding popup Browser language Arabic Coresponding popup I was unable to find anything in the documentation - could you please either point me to the relevant documentation or confirm/deny that it is possible to request a language for the popup via tjr javascript API? Kind regards Tomas

I want to add the option to choose an alternative icon inside the app. Is there a way to load an icon asset from within the app? I downloaded Apple’s alternative icon sample, which is supposed to show a list of icons to choose from, but even in the sample, it did not work. So the current solution is to add every alternative icon along with another image asset of the same image to display to the user. This sounds like a waste of bytes. Thank you in advance for any help.

I am developing an application which make use of 2 ornaments anchored to a volumetric window, one used a toolbar and one to display different views. The problem I am facing consistently is that the ornaments seems to scale up or down after moving the volume using the OS handle or starting a GroupActivity session. This first image shows the ornaments as soon as I started the app, no dragging nor group activities: This second images shows them as soon as I join a group activity session: The map, which might seem smaller, has not been touched and has always the same scale. In this last image I had just dragged the entire volume using the OS toolbar, resulting in the ornaments scaling down: This is how the volume and the ornaments are declared: WindowGroup(id: "CityVolume") { let cityVM = CityViewModel(volumeSize: CityView.initialVolumeSize) CityView(cityVM: cityVM) .ornament(attachmentAnchor: .scene(.bottomFront)) { HStack { TourismChartsButton() LandmarksListButton() CenterMapButton() ToggleImmersiveSpaceButton() TrafficDataButton() BusLinesButton() } .padding() .offset(z: 10) .rotation3DEffect(Angle(degrees: 15), axis: (x: 1.0, y: 0.0, z: 0.0)) } .ornament(attachmentAnchor: .scene(.back)) { ZStack { if AppModel.Instance.tourismVM.isChartViewVisible { TourismChartsView() } if AppModel.Instance.busLinesVM.isDataViewEnabled { BusLineView() } } } .task(observeGroupActivity) .onAppear { appModel.cityVM = cityVM } } .windowStyle(.volumetric) .windowResizability(.contentSize) .volumeWorldAlignment(.gravityAligned) .defaultSize(CityView.initialVolumeSize, in: .meters) It happens also without starting a SharePlay session, but not as frequently as during SharePlay. Experienced the same behaviour with toolbars. Am I doing something wrong with how I created the ornaments? Am I missing something?

I'm currently integrating SwiftUI into an AppKit based application and was curious if the design pattern below was viable or not. In order to "bridge" between AppKit and SwiftUI, most of my SwiftUI "root" views have aViewModel that is accessible to the SwiftUI view via @ObservedObject. When a SwiftUI views need to use NSViewRepresentable I'm finding the use of a ViewModel and a Coordinator to be an unnecessary layer of indirection. In cases where it makes sense, I've just used the ViewModel as the Coordinator and it all appears to be working ok, but I'm curious if this is reasonable design pattern or if I'm overlooking something. Consider the following pseudo code: // 1. A normal @ObservedObject acting as the ViewModel that also owns and manages an NSTableView. @MainActor final class ViewModel: ObservedObject, NSTableView... { let scrollView: NSScrollView let tableView: NSTableView @Published var selectedTitle: String init() { // ViewModel manages tableView as its dataSource and delegate. tableView.dataSource = self tableView.delegate = self } func reload() { tableView.reloadData() } // Update view model properties. // Simpler than passing back up through a Coordinator. func tableViewSelectionDidChange(_ notification: Notification) { selectedTitle = tableView.selectedItem.title } } // 2. A normal SwiftUI view, mostly driven by the ViewModel. struct ContentView: View { @ObservedObject model: ViewModel var body: some View { Text(model.selectedTitle) // No need to pass anything down other than the view model. MyTableView(model: model) Button("Reload") { model.reload() } Button("Delete") { model.deleteRow(...) } } } // 3. A barebones NSViewRepresentable that just vends the required NSView. No other state is required as the ViewModel handles all interactions with the view. struct MyTableView: NSViewRepresentable { // Can this even be an NSView? let model: ViewModel func makeNSView(context: Context) -> some NSView { return model.scrollView } func updateNSView(_ nsView: NSViewType, context: Context) { // Not needed, all updates are driven through the ViewModel. } } From what I can tell, the above is working as expected, but I'm curious if there are some situations where this could "break", particularly around the lifecycle of NSViewRepresentable Would love to know if overall pattern is "ok" from a SwiftUI perspective.

Let's say you have a protocol that can work with both classes and structs but you want to have a uniform UI to make edits. What is the recommended way to have one view that will take both? App import SwiftUI @main struct ObservationTesterApp: App { var body: some Scene { WindowGroup { ContentView(existence: Existence()) } } } Types import Foundation protocol Dateable { var timestamp:Date { get set } } struct Arrival:Dateable { var timestamp:Date } @Observable class Existence:Dateable { var timestamp:Date init(timestamp: Date) { self.timestamp = timestamp } } extension Existence { convenience init() { self.init(timestamp: Date()) } } ContentView, etc // // ContentView.swift // ObservationTester // // import SwiftUI struct EditDateableView<TimedThing:Dateable>:View { @Binding var timed:TimedThing //note that this currently JUST a date picker //but it's possible the protocol would have more var body:some View { DatePicker("Time To Change", selection: $timed.timestamp) } } #Preview { @Previewable @State var tt = Arrival(timestamp: Date()) EditDateableView<Arrival>(timed: $tt) } struct ContentView: View { @State var arrival = Arrival(timestamp: Date()) @Bindable var existence:Existence var body: some View { //this work around also not allowed. "self is immutable" // let existBinding = Binding<Existence>(get: { existence }, set: { existence = $0 }) VStack { EditDateableView(timed: $arrival) //a Binding cant take a Bindable //EditDateableView<Existence>(timed: $existence) } .padding() } } #Preview { ContentView(existence: Existence()) }

I am working on creating a custom Popup View based on a .fullscreenCover. The .fullscreenCover is used to place the Popup content on screen on a semi-transparent background. While this works on iOS 18, there is a problem on iOS 17: When the Popup content contains a .sheet, the background is not transparent any more but opaque. Image: iOS 17. When showing the Popup an opaque background covers the main content. When tapping on the background it turns transparent. Image: iOS 18. Everything works as intended. When showing the Popup the main background is covered with a semi-transparent background. Removing the .sheet(...) from the Popup content solves the problem. It does not matter if the sheet is used or not. Adding it to the view code is enough to trigger the problem. Using a .sheet within a .fullscreenCover should not be a problem as far as I know. Is this a bug in iOS 17 or is there something wrong with my code? Code: struct SwiftUIView: View { @State var isPresented: Bool = false @State var sheetPresented: Bool = false var body: some View { ZStack { VStack { Color.red.frame(maxHeight: .infinity) Color.green.frame(maxHeight: .infinity) Color.yellow.frame(maxHeight: .infinity) Color.blue.frame(maxHeight: .infinity) } Button("Show") { isPresented = true } .padding() .background(.white) Popup(isPresented: $isPresented) { VStack { Button("Dismiss") { isPresented = false } } .frame(maxWidth: 300) .padding() .background( RoundedRectangle(cornerRadius: 20) .fill(.white) ) .sheet(isPresented: $sheetPresented) { Text("Hallo") } } } } } struct Popup<Content: View>: View { @Binding var isPresented: Bool let content: () -> Content init(isPresented: Binding<Bool>, @ViewBuilder _ content: @escaping () -> Content) { _isPresented = isPresented self.content = content } @State private var internalIsPresented: Bool = false @State private var isShowing: Bool = false let transitionDuration: TimeInterval = 0.5 var body: some View { ZStack { } .fullScreenCover(isPresented: $internalIsPresented) { VStack { content() } .frame(maxWidth: .infinity, maxHeight: .infinity) .background( Color.black.opacity(0.5) .opacity(isShowing ? 1 : 0) .animation(.easeOut(duration: transitionDuration), value: isShowing) .ignoresSafeArea() ) .presentationBackground(.clear) .onAppear { isShowing = true } .onDisappear { isShowing = false } } .onChange(of: isPresented) { _ in withoutAnimation { internalIsPresented = isPresented } } } } extension View { func withoutAnimation(action: @escaping () -> Void) { var transaction = Transaction() transaction.disablesAnimations = true withTransaction(transaction) { action() } } }

I have a LIVE imessage sticker app with simple UI that is auto installed under the sticker section. And i am trying to rewrite the app but the new app, when testing, always publish under the imessage app category instead of under the sticker category. here is the live app on app store: https://apps.apple.com/us/app/qoobee-agapi-stickers/id1176590163 Does anyone know how to get my imessage app published under the sticker category?

I'm still unable to achieve the effects as shown. The tinting of the buttons in a .toolbar. The iOS Beta 2 shows in Mail show at can be done. The creation of a true clear glass container as use extensively in iOS26.

Anybody can help me with the problems of splashboard? My request is to create a launchScreen.storyboard that can follows system's theme. So in the storyboard i use the image set resource which is created in Assets.xcassets. But i encountered the following problems： when i use image set resource，the splashboard is black, seems like springboard fail to generate the ktx file. But when i move the same image file to the root of Resource directory, it works. Why???? Some image works when it is put in Image set, some file can't. But all file don't work when the image set contains both light image and dark image. Why??? Suddenly it works for when i change compression attribute to lossess，so i guess the problems hanppened when my image is compressed. And two days later, the splash board is dark again when i debug. So what is the cache strategy for the splash board and the image resource used. How can i clear the cache, delete the app is not enough? Should i restart my phone? That's all, anybody can help me?

I noticed that sometimes TextKit2 decides to crop some text instead of soft-wrapping it to the next line. This can be reproduced by running the code below, then resizing the window by dragging the right margin to the right until you see the text with green background (starting with “file0”) at the end of the first line. If you now slowly move the window margin back to the left, you’ll see that for some time that green “file0” text is cropped and so is the end of the text with red background, until at some point it is soft-wrapped on the second line. I just created FB18289242. Is there a workaround? class ViewController: NSViewController { override func loadView() { let textView = NSTextView(frame: CGRect(x: 0, y: 0, width: 400, height: 400)) let string = NSMutableAttributedString(string: "file0\t143548282\t1970-01-01T00:00:00Z\t1\t1f40fc92da241694750979ee6cf582f2d5d7d28e18335de05abc54d0560e0f5302860c652bf08d560252aa5e74210546f369fbbbce8c12cfc7957b2652fe9a75", attributes: [.foregroundColor: NSColor.labelColor, .backgroundColor: NSColor.red.withAlphaComponent(0.2)]) string.append(NSAttributedString(string: "file0\t143548290\t1970-01-01T00:05:00Z\t 2\t0f6460d0ed7825fed6bda0f4d9c14942d88edc7ff236479212e69f081815e6f1742c272753b77cc6437f06ef93a46271c6ff9513c68945075212434080e60c82", attributes: [.foregroundColor: NSColor.labelColor, .backgroundColor: NSColor.green.withAlphaComponent(0.2)])) textView.textContentStorage!.textStorage!.setAttributedString(string) textView.autoresizingMask = [.width, .height] let scrollView = NSScrollView(frame: CGRect(x: 0, y: 0, width: 400, height: 400)) scrollView.documentView = textView scrollView.hasVerticalScroller = true scrollView.translatesAutoresizingMaskIntoConstraints = false view = scrollView } }

Hi everyone, I'm working with AVPlayerViewController in a tvOS/iOS app and ran into a limitation that I believe some developers face. When using player.currentItem?.currentTime(), we only get the playback time—which is fine while the video is playing. But when the player is paused and the user drags the scrubber, there's no public API to get the time that is currently being previewed under the scrubber thumb (stick), but there's no way to read it programmatically. This becomes a problem when trying to show thumbnail previews or display metadata tied to the scrubbed position.

Hi Team! Has anyone found a reliable way to detect CarPlay connection without the app needing to be in the foreground? I’m exploring a concept where, for example, as someone nears home while driving, a prompt appears on the CarPlay screen asking “Would you like to turn on the lights / open garage?” triggered by proximity and CarPlay connection. Would be cool to have it work automatically, but knowing you're in the car is kind of important. From what I can see, apps can’t reliably detect CarPlay connection unless they’re actively open on the CarPlay screen. Most background detection methods (like external screen connect notifications) appear deprecated. That is, unless you're specifically approved as a "messaging" or "navigation" app that appear to get special privilages to send alerts from the background. If I send an alert (or poll Carplay periodically) it just gives silent/dead response. Is there any approach, framework, entitlement, or UI pattern that could allow a passive trigger or background detection while driving with CarPlay connected? I can't see any way to bring an app to the foreground either. Not looking to abuse any rules... just want to understand if anyone’s found a clean, approved workaround. Thanks in advance!

There appears to be a visual bug when using .searchable in a child view that’s pushed via NavigationLink inside a NavigationStack. Specifically, the search bar appears briefly in the wrong position (or animates in an unexpected way) during the transition to the child view. This issue does not occur when using NavigationView instead of NavigationStack. Steps to Reproduce: Create a TabView with a single tab containing a NavigationStack. Push from a ContentView to a DetailsView using NavigationLink. Add a .searchable modifier to both the ContentView and DetailsView. Run the app and tap a row to navigate to the details view. Expected Behavior The search bar in the DetailsView should appear smoothly and in the correct position as the view transitions in, just like it does under NavigationView. Actual Behavior When the DetailsView appears, the search bar briefly animates or appears in the wrong location before settling into place. This results in a jarring or buggy visual experience. Feedback: FB17031212 Here is a reddit thread discussing the issue as well https://www.reddit.com/r/SwiftUI/comments/137epji/navigation_stack_with_search_bar_has_a_bug_and_a/ I hope that an Apple engineer can get this fixed soon. It's frustrating to have new APIs come out with the old deprecated yet there are still obvious bugs two years later. import SwiftUI public enum Tab { case main } struct AppTabNavigation: View { @State private var tabSelection = Tab.main var body: some View { TabView(selection: $tabSelection) { NavigationStack { ContentView() } .tag(Tab.main) .tabItem { Label("Main", systemImage: "star") } } } } struct ContentView: View { @State private var searchText = "" var body: some View { List(0..<100) { i in NavigationLink("Select \(i)", value: i) } .navigationTitle("Main") .searchable(text: $searchText) .navigationDestination(for: Int.self) { i in DetailsView(i: i) } } } struct DetailsView: View { @State private var searchText = "" let i: Int // MARK: - Body var body: some View { List { ForEach(0..<10, id: \.self) { i in Text("Hello \(i)") } } .navigationTitle(i.formatted()) .searchable(text: $searchText) } }

I'm developing a CarPlay version of my app, with the CarPlay EV Charging App entitlement (com.apple.developer.carplay-charging). However, I would like to use the Search template to searching for charging stations — but it seems this template is only available for Navigation Apps(maps). In this case, what is the recommended approach? Is it possible to apply both entitlements simultaneously and use the Search template only?

I have an image in the xcassets file which is localized for different languages. When setting App language to Traditional Chinese, it always displays the Simplified Chinese image. This happens on latest iOS 18.5 system, but not on a lower system version. The feedback assistant ID is FB17663546

When attempting to replicate the tvOS Settings menu layout, where the screen is divided horizontally into two sections, placing a NavigationStack or a Form view on either side of the screen causes focusable views (such as Button, TextField, Toggle, etc.) to be visually clipped when they receive focus and apply the default scaling animation. Specifically: If the Form or NavigationStack is placed on the right side, the left edge of the focused view gets clipped. If placed on the left side, the right edge of the focused view gets clipped. This issue affects any focusable child view inside the Form or NavigationStack when focus scaling is triggered. Example code: struct TVAppMenuMainView: View { var body: some View { VStack { Text("Settings Menu") .font(.title) HStack { VStack { Text("Left Pane") } .frame(width: UIScreen.main.bounds.width * 0.4) // represents only 40% of the screen .frame(maxHeight: .infinity) .padding(.bottom) Divider() NavigationStack { Form { // All the buttons will get cut on the left side when each button is focused Button("First Button"){} Button("Second Button"){} Button("Third Button"){} Button("Forth Button"){} } } } .frame(maxHeight: .infinity) .frame(maxWidth: .infinity) } .background(.ultraThickMaterial) } } How it looks: What I have tried: .clipped modifiers .ignoresSafeArea Modifying the size manually Using just a ScrollView with VStack works as intended, but as soon as NavigationStack or Form are added, the buttons get clipped. This was tested on the latest 18.5 tvOS BETA

Hi, I've got an app that displays markdown in UITextView / NSTextView. I would like it to behave like Notes app does, that is if user types the line start modifier, e.g: "# " or "> " I would like the keyboard to show a capitalized letters. I've tried looking into overriding insertText - and it breaks the predictive text (can not insert white space). I've tried implementing UITextInputTokenizer but no luck either. Like I said, I see the Notes app does it perfectly, so maybe I'm missing something obvious or there is a way to do it without interrupting the auto-correction and predictive text. Ideally same thing can be applied to the NSTextView as the app support both platforms.

Hi Apple Developer Team, In my tvOS app built with SwiftUI, I have a tab-based interface with several sections. The first tab (index 0) is the Home tab. Other tabs include Contact, WiFi, Welcome, etc. I want to handle the remote's Menu / Back button (.onExitCommand) so that: If the user is on any tab other than Home (tabs 1, 2, 3, etc.), pressing the Menu button takes them back to the Home tab. If the user is already on the Home tab, then pressing the TV/Home button (not Menu) behaves as expected — suspending or exiting the app (handled by the system, no code involved). Here's a simplified version of what I implemented: .onExitCommand { if selectedTab != 0 { selectedTab = 0 focusedTab = 0 } else { // Let system handle the exit when user presses the TV/Home button } } This behavior ensures users don’t accidentally exit the app when they're browsing other tabs, and provides a consistent navigation experience. Question: Is this an acceptable and App Store-compliant use of .onExitCommand on tvOS? I'm not calling exit(0) or trying to force-terminate the app — just using .onExitCommand for in-app navigation purposes. Any official guidance or best practices would be greatly appreciated! Thanks, Prashant
