I'm using xcode 16.1 with SwiftUI. I have a program that needs another screen. How can I add navigation? All the youtube videos show you how to add navigation to a new program. Is there a video that shows you how to add navigation to an existing program? Any instruction would help. Thanks

Hello, I am having the following issue: I am using the packages DSWaveformImage and DSWaveformImageViews if that matters. My code's goal is to generate waveform images from files embedded in the application. That works great on a simulator device, but when I run the code on a physical device (iPhone 15 Pro, iOS 18.2), I get this error (shown in the attached screenshot below):

When I present a UIDocumentPickerViewController I want it to occupy the fullscreen but it never displays as fullscreen The modalPresentationStyle seems to have no effect no matter what I set it to Running the code with DispatchQueue.main.async did not help either Here is the code Anybody got any suggestions? `@objc private func plusButtonPressed() { DispatchQueue.main.async { let picker = UIDocumentPickerViewController(documentTypes: [kUTTypeData as String], in: .import) picker.delegate = self picker.modalPresentationStyle = .fullScreen self.present(picker, animated: true) } }`

I am trying to carry out repairs on my computer, it is an old MacBook Pro which I really appreciate, and it works very well, before attempting a hardware repair, I am exhausting all the software resources, in one of its support forums I found a supposed solution, I just can't see the assigned plist, but I see that it appears in the example as root within xcode, could you help me with what the steps would be to enter root mode and thus be able to make the relevant adjustment , I attach the link to the example. thank you so much https://discussions.apple.com/thread/3114550?sortBy=rank) The example can be found in Grant Bennet-Alder coment

I have been using the QLPreviewController in an app for some time now and have always gotten a flurry of constraint warnings when it launches which I have ignored. I have looked at them and don't believe they are due to my code and the app seems to work. Tried to attach a simple app that loads a ViewController with a single button that when pressed creates an object that generates and displays a CSV file via QLPreviewController but can't.

I have an app with the following model: @Model class TaskList { @Attribute(.unique) var name: String // Relationships var parentList: TaskList? @Relationship(deleteRule: .cascade, inverse: \TaskList.parentList) var taskLists: [TaskList]? init(name: String, parentTaskList: TaskList? = nil) { self.name = name self.parentList = parentTaskList self.taskLists = [] } } If I run the following test, I get the expected results - Parent has it's taskLists array updated to include the Child list created. I don't explicitly add the child to the parent array - the parentList relationship property on the child causes SwiftData to automatically perform the append into the parent array: @Test("TaskList with children with independent saves are in the database") func test_savingRootTaskIndependentOfChildren_SavesAllTaskLists() async throws { let modelContext = TestHelperUtility.createModelContext(useInMemory: false) let parentList = TaskList(name: "Parent") modelContext.insert(parentList) try modelContext.save() let childList = TaskList(name: "Child") childList.parentList = parentList modelContext.insert(childList) try modelContext.save() let fetchedResults = try modelContext.fetch(FetchDescriptor<TaskList>()) let fetchedParent = fetchedResults.first(where: { $0.name == "Parent"}) let fetchedChild = fetchedResults.first(where: { $0.name == "Child" }) #expect(fetchedResults.count == 2) #expect(fetchedParent?.taskLists.count == 1) #expect(fetchedChild?.parentList?.name == "Parent") #expect(fetchedChild?.parentList?.taskLists.count == 1) } I have a subsequent test that deletes the child and shows the parent array being updated accordingly. With this context in mind, I'm not seeing these relationship updates being observed within SwiftUI. This is an app that reproduces the issue. In this example, I am trying to move "Finance" from under the "Work" parent and into the "Home" list. I have a List that loops through a @Query var taskList: [TaskList] array. It creates a series of children views and passes the current TaskList element down into the view as a binding. When I perform the operation below the "Finance" element is removed from the "Work" item's taskLists array automatically and the view updates to show the removal within the List. In addition to that, the "Home" item also shows "Finance" within it's taskLists array - showing me that SwiftData is acting how it is supposed to - removed the record from one array and added it to the other. The View does not reflect this however. While the view does update and show "Finance" being removed from the "Work" list, it does not show the item being added to the "Home" list. If I kill the app and relaunch I can then see the "Finance" list within the "Home" list. From looking at the data in the debugger and in the database, I've confirmed that SwiftData is working as intended. SwiftUI however does not seem to observe the change. ToolbarItem { Button("Save") { list.name = viewModel.name list.parentList = viewModel.parentTaskList try! modelContext.save() dismiss() } } To troubleshoot this, I modified the above code so that I explicitly add the "Finance" list to the "Home" items taskLists array. ToolbarItem { Button("Save") { list.name = viewModel.name list.parentList = viewModel.parentTaskList if let newParent = viewModel.parentTaskList { // MARK: Bug - This resolves relationship not being reflected in the View newParent.taskLists?.append(list) } try! modelContext.save() dismiss() } } Why does my explicit append call solve for this? My original approach (not manually updating the arrays) works fine in every unit/integration test I run but I can't get SwiftUI to observe the array changes. Even more strange is that when I look at viewModel.parentTaskList.taskLists in this context, I can see that the list item already exists in it. So my code effectively tries to add it a second time, which SwiftData is smart enough to prevent from happening. When I do this though, SwiftUI observes a change in the array and the UI reflects the desired state. In addition to this, if I replace my custom list rows with an OutlineGroup this issue doesn't manifest itself. SwiftUI stays updated to match SwiftData when I remove my explicit array addition. I don't understand why my views, which is passing the TaskList all the way down the stack via Bindable is not updating while an OutlineGroup does. I have a complete reproducible ContentView file that demonstrates this as a Gist. I tried to provide the source here but it was to much for the post. One other anecdote. When I navigate to the TaskListEditorScreen and open the TaskListPickerScreen I get the following series of errors: error: the replacement path doesn't exist: "/var/folders/07/3px_03md30v9n105yh3rqzvw0000gn/T/swift-generated-sources/@_swiftmacro_09SwiftDataA22UIChangeDetectionIssue20TaskListPickerScreenV9taskLists33_A40669FFFCF66BB4EEA5302BB5ED59CELL5QueryfMa.swift" I saw another post regarding these and I'm wondering if my issue is related to this. So my question is, do I need to handle observation of SwiftData models containing arrays differently in my custom views? Why do bindings not observe changes made by SwiftData but they observe changes made explicitly by me?

Hi, I am having some troubles creating a "nested" RealityView content using MapKit attachment. I am building a visionOS app that has horizontal MapKit map as an attachment to RealityView. I want to display 3D pins on that map, therefore I am using native map annotation and inside of these annotations, I create a new RealityView just for the 3D pin. This worked completely fine, unitil I wanted to have those RealityViews interact with each other. By interaction of those RealityViews I mean that I wanted to group entities from the first "main" RealityViews content with the 3D pins using ModelSortGroupComponent. Why I want this? I want to make the map circular, that is not a problem. Problem is that when I move the map with 3D pins, these pins have their own RealityView space and are only bounded by volumetric window dimensions. What happes is that these pins float next to the map (shown on attached image). So I came up with this solution: create a custom "toroid" like 3D entity model that occludes the pins that go outside the map region. In order to occlude only the pins, I need to use ModelSortGroupComponent to group the "toroid" entity with 3D pins entities (as described in another forum thread). To summarize: need the content of the superior RealityView to interact with map attachment annotations RealityView content in order to group them. There might be of course another, better way to achieve my whole goal, so I would naturally appreciate any help or guidance. Image below showing 3D pins on circular map. Since pins RealityView does no know anything about other RealityViews, it just overlows and hangs in space until is cropped by volumetric window boundary. Simplified code: var body: some View { let modelSortGroup = ModelSortGroup(depthPass: .prePass) RealityView { content, attachments in var mainEntity = Entity() // My other entities here... if let mapAttachment = attachments.entity(for: "mapAttachment") { // Edit map properties, position, horizontal layout etc. mainEntity.addChild(mapAttachment) } // Create and add to content mask "toroid" entity mapMaskEntity. Use OcclusionMaterial() material. mapMaskEntity.components.set(ModelSortGroupComponent(group: modelSortGroup, order: 0)) // For all pins, somehow also set the group // 3DPinEntity.components.set(ModelSortGroupComponent(group: modelSortGroup, order: 1)) content.add(mainEntity) } attachments: { Attachment(id: "mapAttachment") { Map { ForEach(mapViewModel.clusters, id: \.id) { cluster in Annotation("", coordinate: cluster.coordinate) { MapPin3DView(cluster: cluster) } } } .clipShape(Circle()) } } } // MapPin3DView is an map annotation view that includes a model of 3D pin and some details like image etc., uses RealityView. struct MapPin3DView: View { var body: some View { RealityView { content in // 3D pin entities... } } }

Hello everyone! I've encountered an issue related to SwiftUI and StoreKit. Please take a look at the SwiftUI code snippet below: import SwiftUI struct ContentView: View { var body: some View { NavigationStack { List { NavigationLink { Page1() } label: { Text("Go to Page 1") } } } } } struct Page1: View { @Environment(\.dismiss) private var dismiss @State private var string: String = "" var body: some View { List { NavigationLink { List { Page2(string: $string) .simpleValue(4) } } label: { Text("Tap this button will freeze the app") } } .navigationTitle("Page 1") } } struct Page2: View { @Binding var string: String? init(string: Binding<String>) { self._string = Binding(string) } var body: some View { Text("Page 2") } } extension EnvironmentValues { @Entry var simpleValue: Int = 3 } extension View { func simpleValue(_ value: Int) -> some View { self.environment(\.simpleValue, value) } } This view runs normally until the following symbol is referenced anywhere in the project: import StoreKit extension View { func notEvenUsed() -> some View { self.manageSubscriptionsSheet(isPresented: .constant(false)) } } It seems that once the project links the View.manageSubscriptionsSheet(isPresented:) method, regardless of whether it's actually used, it causes the above SwiftUI view to freeze. Steps to Reproduce: Clone the repository: https://github.com/gongzhang/StrangeFreeze Open it in Xcode 16 and run on iOS 17-18.1 Navigate to the second page and tap the button, causing the app to freeze. Remove manageSubscriptionsSheet(...), then everything will work fine

I have an iOS App which looks great on iPhone, portrait only, which makes a lot of use of UITableViews. On iPad those tables look stretched out in Landscape. On MacOS with Apple Silicon the app can be resized to any size and the table views look very stretched. There are views in the App which users want to resize so limiting app size not an option. I've been modifying the app's table views to limit their width and centre them using constraints. This isn't easy, it's a lot of work as UITableViewController doesn't allow for constraining the table width. Or does it? So I've changed them to UIViewControllers with UITableView imbedded in the root UIView with constraints. Looks really nice. Now I've just run into the limitation that static tables, which I have a number of, aren't allowed to be embedded. So how can I limit the width of them? I really don't want to add a lot of dynamic code. Please tell me there's an simpler, more elegant method to what really makes a much more aesthetically pleasing UI on iOS App running on iPad and MacOS? TIA!

I recently started exploring the latest version of SwiftUI and encountered an issue while working with TabView and NavigationStack. I downloaded the example code provided by Apple and began making changes to explore new SwiftUI features. However, I noticed that the navigation bar "jumps" or resets when switching between tabs, even in their example implementation. Here are some changes which I made below in the files: LibraryView: .navigationTitle("Library") .navigationBarTitleDisplayMode(.inline) .toolbarBackground(Color("AccentColor"),for: .navigationBar) WatchNowView: .navigationTitle("Watch Now") .navigationBarTitleDisplayMode(.inline) .toolbarBackground(Color("AccentColor"),for: .navigationBar) example code url :- destinationVideo I suspect the issue arises because each tab bar item has its own NavigationStack. When we set a navigation title for each view, the NavigationStack resets the navigation bar on view appearance, which causes this visual bug. Thank you!

Hi! I'm attempting to run the Quakes Sample App^1 from macOS. I am running breakpoints and confirming the mapCameraKeyframeAnimator is being called: .mapCameraKeyframeAnimator(trigger: selectedId) { initialCamera in let start = initialCamera.centerCoordinate let end = quakes[selectedId]?.location.coordinate ?? start let travelDistance = start.distance(to: end) let duration = max(min(travelDistance / 30, 5), 1) let finalAltitude = travelDistance > 20 ? 3_000_000 : min(initialCamera.distance, 3_000_000) let middleAltitude = finalAltitude * max(min(travelDistance / 5, 1.5), 1) KeyframeTrack(\MapCamera.centerCoordinate) { CubicKeyframe(end, duration: duration) } KeyframeTrack(\MapCamera.distance) { CubicKeyframe(middleAltitude, duration: duration / 2) CubicKeyframe(finalAltitude, duration: duration / 2) } } But I don't actually see any map animations taking place when that selection changes. Running the application from iPhone simulator does show the animations. I am building from Xcode Version 16.2 and macOS 15.2. Are there known issues with this API on macOS?

I want to get the content present in a note or a mail thread when my cursor is in it on macos. (In the focused element).

Hi! SiriTipView(intent:) shows the first phrase for my App Shortcut, but unlike ShortcutsLink(), does not use the localized applicationName. Hence the phrase shown does not work 😬 Is this a known limitation, any workarounds?

My app has a sort of "HUD" that sits at the top of the screen. It contains some general information about gameplay, and a couple of interactive elements: a scrolling list of text and a button. It's imbedded into the main view like this: struct WindowedInGameView: View { @Environment(GameModel.self) private var gameModel var body: some View { ZStack(alignment: .top) { VStack { HUDTopView() switch(gameModel.game?.location.player_location) { case .plaza: PlazaView() case .city_hall: CityHallView() ///... Lots of additional views... default: Text("Player is in unknown location.") } // --> Position 2 } if gameModel.showConversationView { ... an overlay for NPC conversations... } if (gameModel.showNotificationView) { .. a notification overlay... } } } } If HUDTopView() is at the indicated place at the top of the VStack, none of its interactive elements work: you can't press buttons, you can't scroll the text. Everything looks present and interactive, it just doesn't seem to receive any input. If I move HUDTopView() to the bottom of the VStack (where the comment indicates "Position 2") it works just fine, except it's not where I want it to be located. So far as I can tell, its position alone is disabling it somehow. In either case, any interactive elements in the views from the switch are acting fine, regardless of their position relative to the HUD view. This fails in the same way on iOS, iPadOS, and macOS. (The visionOS implementation doesn't use this main view, so I haven't tried it there). What it isn't: the overlays at the bottom. Commenting them out doesn't change behaviour. the ZStack - I can replace it with an HStack, and it still fails. Anything about the container of this view -- it fails in preview Anything about the HUDTopView() -- a simple button placed there becomes noninteractive, too. I'm at a complete loss for what could possibly be causing this.

I'm trying to test migration between schemas but I cannot get it to work properly. I've never been able to get a complex migration to work properly unfortunately. I've removed a property and added 2 new ones to one of my data models. This is my current plan. enum MigrationV1toV2: SchemaMigrationPlan { static var schemas: [any VersionedSchema.Type] { [SchemaV1.self, SchemaV2.self] } static let migrateV1toV2 = MigrationStage.custom( fromVersion: SchemaV1.self, toVersion: SchemaV2.self, willMigrate: { context in print("Inside will migrate") // Get old months let oldMonths = try context.fetch(FetchDescriptor<SchemaV1.Month>()) print("Number of old months:\(oldMonths.count)") for oldMonth in oldMonths { // Convert to new month let newMonth = Month(name: oldMonth.name, year: oldMonth.year, limit: oldMonth.limit) print("Number of transactions in oldMonth: \(oldMonth.transactions?.count)") print("Number of transactions in newMonth: \(newMonth.transactions?.count)") // Convert transactions for transaction in oldMonth.transactions ?? [] { // Set action and direction let action = getAction(from: transaction) let direction = getDirection(from: transaction) // Update category if necessary var category: TransactionCategory? = nil if let oldCategory = transaction.category { category = TransactionCategory( name: oldCategory.name, color: SchemaV2.Category.Colors.init(rawValue: oldCategory.color?.rawValue ??

At this point it fails with the following line: SwiftData/PersistentModel.swift:726: Fatal error: What kind of backing data is this? SwiftData._KKMDBackingData<Monthly.SchemaV1.Transaction> Anyone know what I can do about this?

My ipAd app is now crashing when being run on a Mac (with designed for iPad emulator). It. has been working a month ago, today was first time I tried in awhile.
