My SwiftData model doesn't have time to update, and the widget gets old data on the timeline I create simple SwiftData app with widget extension. To share swiftdata between widget and app I use the same approach as in sample code "Adopting SwiftData for a Core Data app": let modelContext = ModelContext(DataModel.shared.modelContainer) if let models = try? modelContext.fetch(fetchDescriptor) { // use } After I create/delete/updated model I call: WidgetCenter.shared.reloadAllTimelines() The problem is that the widget receives outdated data as a result of modelContext.fetch. To get the new data I need to call WidgetCenter.shared.reloadAllTimelines() twice or with some delay: // MyModelEditorView private func save() { if let myModel { myModel.title = title } else { let myModel = MyModel( title: title ) modelContext.insert(word) } WidgetCenter.shared.reloadAllTimelines() // i have to call it twice WidgetCenter.shared.reloadAllTimelines() } I couldn't test SampleCode for similar update behavior, because somehow I couldn't get the models into the widget and I only have "No Trip" displayed there. If I remove the second call, the UI is updated immediately and the new title is displayed, but the widget in the timeline receive the old title. I don't understand whether this is the case and I need to update the widget with a delay or am I doing something wrong? BTW: Why is sample code in init we don't use shared container? private let modelContainer: ModelContainer init() { do { // why we don't use DataModel.shared.modelContainer modelContainer = try ModelContainer(for: Trip.self) } catch { fatalError("Failed to create the model container: \(error)") } }

I am experimenting with drag-and-drop on iPadOS. If I drag a JPEG image from a webpage in Safari to my app, I get items of types public.jpeg and public.url. Typically, the URL is the URL of the image. If, however, the image is itself a link, then the URL seems to be the target of the link. Is there some way that I can always get the URL of the image itself? Is there some way that I can determine whether the URL I have received is the URL of the image or of a link?

Hi, I notice a very slow transfer rate when I try to transfer a file picked via .photosPicker. This happens especially when I try to import a 4k/60fps video. SwiftUI: VStack { Button("Pick a video") { model.isPhotoPickerView = true } .photosPicker(isPresented: $model.isPhotoPickerView, selection: $model.selectedImageList, maxSelectionCount: 1, matching: .videos) .onChange(of: model.selectedImageList, { old, new in model.handlePhotoPicker() }) } View Model to handle Photo Picker action: private class PageModel: ObservableObject { //other methods @MainActor public func handlePhotoPicker() { if selectedImageList.isEmpty { return } guard let item = selectedImageList.first else { return } Task { do { if let video = try await item.loadTransferable(type: VideoTransferable.self) { let file = video.url //video url arrived } } catch { //handle error } } } } Now the VideoTransferable : struct VideoTransferable: Transferable { let url: URL static var transferRepresentation: some TransferRepresentation { FileRepresentation(contentType: .movie) { video in SentTransferredFile(video.url) } importing: { received in //takes too much time to import large 4K video recorded from iPhone's main camera let copy = FileManager.documentsDirectory.appendingPathComponent(FolderType.temp.rawValue).appendingPathComponent("video_\(Int64(Date().timeIntervalSince1970 * 1000)).MOV") if FileManager.default.fileExists(atPath: copy.path) { try FileManager.default.removeItem(at: copy) } try FileManager.default.copyItem(at: received.file, to: copy) return Self.init(url: copy) } } } To my surprise this issue doesn't happen when I use a custom UIViewControllerRepresentable to wrap UIImagePickerController() and setting videoExportPreset property of the picker to AVAssetExportPresetPassthrough Can someone point me out where I am wrong?

Hey, I have a use case where I want to show a tip for a menu thats in a toolbar. Here's my approach to attach the tip to the Menu. I also tried to attach it to the Button in the menu but in both cases the tip was not shown. None of the described fixes in this post worked for me, adding .buttonStyle(.borderless) didn't help either ... .toolbar { ToolbarItem(placement: .navigationBarTrailing) { Menu { Button { // ... } label: { // ... } } label: { Image(systemName: "heart") } .popoverTip(Tip()) } } I'm working on a visionOS app

I have an URGENT assignment with detail as below: I have an application and it has an Extension UI for it. When I select an item of popup list on standard UI of application. How can I catch event of this selection in standard UI and do update for Extension UI? Do we have any relationship between Standard UI and Extension UI in MacOS? Please help to share your experience about this technical?

I have some key commands registered in Responder chain on IOS application that reacts to F1-F12 keys. I have bluetooth keyboard connected to ipad that has some default functions assigned to most of F keys and because of that my application doesn't react when i click F key and fires the default behaviour. For example i have callback registered on F1 key that has default function of dimming the screen. When i click F1 key the screen is dimmed and the callback is not fired. When i click on F5 which does not have any default function the callback is called properly. How can i disable this default behaviour or somehow make my application react to FKeys? Keyboard model: A1644 Ipad 6

This problem will occur in Xcode 16 beta and iOS 18 beta, are there any changes to the function of highPriorityGesture in iOS 18? Example code is: import SwiftUI struct ContentView: View { @State private var dragable: Bool = false @State private var dragGestureOffset: CGFloat = 0 var body: some View { ZStack { ScrollViewReader { scrollViewProxy in ScrollView(showsIndicators: false) { cardList .padding(.horizontal, 25) } } } .highPriorityGesture(dragOffset) } var cardList: some View { LazyVStack(spacing: 16) { Text("\(dragGestureOffset)") .frame(maxWidth: .infinity) .padding(.vertical,8) .background { RoundedRectangle(cornerRadius: 8) .fill(.gray) } //Display 100 numerical values in a loop ForEach(0..<100) { index in Text("\(index)") .frame(maxWidth: .infinity) .padding(.vertical,8) .background { RoundedRectangle(cornerRadius: 8) .fill(.gray) } } } } var dragOffset: some Gesture { DragGesture() .onChanged { value in if abs(value.translation.width) > 25 { dragable = true dragGestureOffset = value.translation.width } } .onEnded { value in if abs(value.translation.width) > 25 { dragable = false dragGestureOffset = 0 } } } }

i use @Observable @Observable class TextClass { var text: String = "" } @State struct ContentView: View { @State var text: TextClass = .init() var body: some View { Form { Text(text.text) Button("upup") { text.text += "1" } } Form { ChildView(text: text) } } } struct ChildView: View { @State var text: TextClass var body: some View { Text (text.text) Button("upup Child") { text.text += "2" } } } @Binding struct ContentView: View { @State var text: TextClass = .init() var body: some View { Form { Text(text.text) Button("upup") { text.text += "1" } } Form { ChildView(text: $text) } } } struct ChildView: View { @Binding var text: TextClass var body: some View { Text (text.text) Button("upup Child") { text.text += "2" } } } @Bindable struct ContentView: View { @State var text: TextClass = .init() var body: some View { Form { Text(text.text) Button("upup") { text.text += "1" } } Form { ChildView(text: text) } } } struct ChildView: View { @Bindable var text: TextClass var body: some View { Text (text.text) Button("upup Child") { text.text += "2" } } } What are the differences between @State, @Binding, and @Bindable, all of which function similarly for bidirectional binding? Which one should I use? I'm curious about the differences between the three.

onContinueUserActivity(CSSearchableItemActionType, perform) works as expected on iOS when we search and select an item from Spotlight, but nothing happens when we do the same on a SwiftUI macOS app. var body: some Scene { WindowGroup { MyView() .onContinueUserActivity(CSSearchableItemActionType, perform: handleSpotlight) } } func handleSpotlight(_ userActivity: NSUserActivity) { // Is not called... } How can we respond to a user clicking a Spotlight result from our apps on macOS?

Hi everyone, Like so many before me, i tried to install my app to test widgets, live activities & dynamic island implementation on a real device or on the simulator (neither works). The problem is that when I try to run the project I get this message : "SendProcessControlEvent:toPid: encountered an error: Error Domain=com.apple.dt.deviceprocesscontrolservice Code=8 "Failed to show Widget 'fr.example.LiveActivities.LiveWidget' error: Error Domain=FBSOpenApplicationServiceErrorDomain Code=1 "The request to open "com.apple.springboard" failed." UserInfo={NSLocalizedFailureReason=The request was denied by service delegate (SBMainWorkspace). [......]". The first thing I tried was looking on Apple's forum and StackOverflow for a solution but after 1hour trying almost eveyrthing, nothing seemed to resolve my problem. Does anyone has an idea of how I could try to fix it ? I would love to show this project in my portfolio in order to find an apprenticeship, but I can't until I find a way to fix this. Thanks a lot!

I can intercept the "Return" button and "Shift+Return" on an iPad's external Bluetooth keyboard with the TextField "onKeyPress" method. But - this always dismisses the keyboard. It looks like the TextField loses focus. This happens whether I return ".handled" or ".ignored". How can I maintain focus on the TextField and not have the keyboard dismissed?

The SF Symbols app 6.0 (99) does not export the ‘Can Rotate’ property of layers when exporting a symbol via File > Export Symbol. Without this, all the new fantastic edit functions in the app related to rotating in SF Symbols is completely useless. This issue with the SF Symbols 6 app can be reproduced by exporting a rotatable symbol like fan.desk, and then by importing the result as custom symbol. When inspecting ‘Group 1’ of the imported symbol, it is no longer marked as rotatable. SF Symbols app 6.0 is still in beta, but hasn't been updated since 10 June. Hopefully this bug will be solved in the release version, or earlier. Does anyone know how to manually add the missing rotation info to the exported SVG file?

After experiencing the official demo (https://developer.apple.com/documentation/visionos/destination-video) on a real device and a demo, I tried to change the poster of the to-be-played list displayed by customOverlayViewController in the demo to a VStack layout. The poster in customOverlayViewController could not fully respond to click events.

I found a very strange bug while using SwiftUI, and the following code is the minimum required to reproduce it. When I press the 'Go to page2' button, the CPU load goes to 100% and the memory usage keeps increasing. What's wrong with this code? I tried to search for a day but could not find any answer. import SwiftUI struct ContentView: View { var body: some View { NavigationStack { Page1() .environmentObject(Foo()) } } } class Foo: ObservableObject { init() {} } struct Page1: View { u/EnvironmentObject private var viewModel: Foo u/Binding var value: Int init() { self._value = .init(get: { 0 }, set: { _ in }) } u/State private var id: UUID? = nil var body: some View { NavigationLink(value: 0) { Text("Go to page2") .padding() .foregroundStyle(.white) .background(.black) .cornerRadius(12) } .navigationDestination(for: Int.self) { _ in Page2( onComplete: { print("value", value) } ) } } } struct Page2: View { public init(onComplete _: u/escaping () -> Void) {} public var body: some View { Text("This is Page2") .task { print("hi") } } }

ViewControllers for the 8th and higher tabs are not displayed in the elevated Tab Bar. However, I am able to select these tabs both in the Tab Bar and the side bar. func setTabs(){ let colors = [UIColor.red,.systemGray6,.green,.systemMint,.cyan,.yellow,.blue,.magenta] var tabs = [UITab]() let range = 0...10 for index in range { if #available(iOS 18.0, *) { let tab = UITab(title: "Tab_\(index)", image: UIImage(systemName: "globe"), identifier: "tab__\(index)", viewControllerProvider: {tab in let vc = UIViewController() vc.view.backgroundColor = colors[index%colors.count] return vc }) tabs.append(tab) } } tabbarController.setTabs(tabs, animated: true) }

Hi , I am new to SwiftUI and Mac/iOS concepts so am on a very steep learning curve. If this is not the correct forum for this please let me know and I will delete and post elsewhere ... Basically I am doing a favor for a friend and writing a simple data collection app for his iPad in Swift... it consists of a quite long list list of items to select from, each of which will have several possible values. Clicking on a "Change" button next to each item will bring up a list of possible values to choose from. So .... The code works except that the list is displayed as an "icon" and has to be clicked to display the items to choose from ... **How do I get the list to display automatically when instanced without having to click on the List icon ? ** Code: I have a list view which is called as the result of a button press: Button(action: { isShowingList=true When the View is refreshed (State variable) results in the Selectable List view as follows: struct TechReportView: View { @State private var isShowingList = false var body: some View { if isShowingList { // display a selectable list SelectableListView(selectedItem: $selectedItem, isShowingList: $isShowingList, items: $copyList, ) } else { // show list of items and current values} The List View is as follows struct SelectableListView: View { @Binding var selectedItem: String? @Binding var isShowingList: Bool @Binding var items : [String] var key : String @Binding var toChange : String var body: some View { VStack() { NavigationView { List(items, id: \.self) { item in HStack { Text(item) Spacer() if item == selectedItem { Image(systemName: "checkmark") .foregroundColor(.blue) } } .contentShape(Rectangle()) .onTapGesture { selectedItem = item toChange = item isShowingList = false setSKeyData(key, selectedItem!) } } .navigationTitle("Select Item") .navigationBarItems(trailing: Button("Cancel") { isShowingList = false }) } } } }
