I don't believe it's possible today to access the icon and tint color of a MapFeature although this would be incredibly helpful in the app that I'm building presently as I'm storing places in SwiftData and would like to use the same icon and tint color when listing places in the app. It would be awesome if this were possible in the next version of iOS, iPadOS visionOS etc., if not presently possible.

Hi, The dataModule in code below is a swiftData object being passed to the view and its property as key path but when trying to modify it I'm getting the error ."Cannot assign through subscript: 'self' is immutable" how to solve this issue ? Kind Regards struct ListSel<T: PersistentModel>: View { @Bindable var dataModule: T @Binding var txtValue: String var keyPath: WritableKeyPath<T, String> var turncate: CGFloat? = 94.0 var image = "" var body: some View { HStack { Text(txtValue) .foregroundColor(sysSecondary) .font(.subheadline) .onChange(of: txtValue) { value in dataModule[keyPath: keyPath] = value } Image(systemName: image) .foregroundColor(sysSecondary) .font(.subheadline) .imageScale(.small) .symbolRenderingMode(.hierarchical) .scaleEffect(0.8) } .frame(width: turncate, height: 20, alignment: .leading) .truncationMode(.tail) } }

Is there really no way to hide a TabItem using the built-in TabView? I have 6 pages, but the 6th one I want hidden from the bottom tab bar, because I have a button that programmatically navigates to it on the navigation bar. I did not want to have to code a custom tab bar due to losing some useful features like pop to root in Navigation Stack.

In my visionOS app, I have an initial WindowGroup (no parameters), which opens correctly on application launch. I have multiple other WindowGroup(for:) closures in the app, too. If I open one of the other WindowGroup(for:) windows, then close the initial window, I can't get the initial window back. If I close the second window, then tap on app icon, the second window reappears, but the initial window isn't shown. The only way to get the initial window back, once it's closed, is to force-quit the app and restart. A one-file reproducible example is below. In this example, the "button tapped" window is the second window. What do I need to do to get the initial window back? Note this problem is in a visionOS app. But I've been able to reproduce even if I remove the RealityKitContent package from the target. If I close, say, Safari's only window, then Safari exits, and shows me its window when I relaunch. The behavior I'd like to see is that when I "click" the app icon, the app presents its main window again. I have also tried giving the WindowGroup an id. That does allow me to openWindow from another window (could use a toolbar item for that), but it doesn't get the main window to appear on launch, and I end up with multiple copies of the Main window. import SwiftUI @main struct Limbo_MREApp: App { var body: some Scene { // I've also tried this form, same result // WindowGroup(id: "main") { WindowGroup { ContentView() } WindowGroup(for: String.self) { $string in if let string { Text(string) .font(.extraLargeTitle2) } } } } struct ContentView: View { @Environment(\.openWindow) var openWindow var body: some View { VStack { Text("Hello, world!") Button("Tap Me", systemImage: "doc.on.doc") { openWindow(value: "button tapped") } } } }

I want to share UserDefaults between main App and macOS Widget, in iOS I can do it using AppGroups, but how to do it between macOS Widget and main App, because macOS widget's AppGroup require to use "Team Identifier" as prefix and main App's AppGroup require prefix to be "group" so how can I share UserDefaults between the two?

I have an app with a TabView containing a view representable containing a SwiftUI View with a toolbar. The representable is providing the toolbar while the .toolbar modifier provides the content. Everything works normally on iOS 17, but on iOS 18 the toolbar contents are not showing. Is this a iOS 18 bug? See the code below for a simplified example. import SwiftUI @main struct TestApp: App { @State var selection: String = "one" var body: some Scene { WindowGroup { TabView(selection: $selection) { Representable() .tabItem { Text("One") } .tag("one") } } } } struct Representable: UIViewControllerRepresentable { let navigationController = UINavigationController() func makeUIViewController(context: Context) -> UINavigationController { navigationController.pushViewController(UIHostingController(rootView: ToolbarView()), animated: false) return navigationController } func updateUIViewController(_ uiViewController: UINavigationController, context: Context) {} } struct ToolbarView: View { var body: some View { NavigationLink("Navigate") { ToolbarView() } .toolbar { ToolbarItem(placement: .principal) { Text("Top") } } } }

Hello, since the last version of iOS and WatchOS I have a problem with this code. This is the minimal version of the code, it have two pickers inside a view of a WatchOS App. The problem its with the focus, I can't change the focus from the first picker to the second one. As I said before, it was working perfectly in WatchOS 10.0 but in 11 the problems started. struct ParentView: View { @FocusState private var focusedField: String? var body: some View { VStack { ChildView1(focusedField: $focusedField) ChildView2(focusedField: $focusedField) } } } struct ChildView1: View { @FocusState.Binding var focusedField: String? @State private var selectedValue: Int = 0 var body: some View { Picker("First Picker", selection: $selectedValue) { ForEach(0..<5) { index in Text("Option \(index)").tag("child\(index)") } }.pickerStyle(WheelPickerStyle()).focused($focusedField, equals: "first") } } struct ChildView2: View { @FocusState.Binding var focusedField: String? @State private var selectedValue: Int = 0 var body: some View { Picker("Second Picker", selection: $selectedValue) { ForEach(0..<5) { index in Text("Option \(index)").tag("childTwo\(index)") } }.pickerStyle(WheelPickerStyle()).focused($focusedField, equals: "second") } } When you do vertical scrolling on the second picker, the focus should be on it, but it dosnt anything. I try even do manually, setting the focusState to the second one, but it sets itself to nil. I hope that you can help me, thanks!

I am using a Mac Catalyst with SwiftUI for our document-based app with DocumentGroup. The issue is that when we create a new document or open an existing one, the opened view is completely blank. It is only blank/empty when the "Optimzie for Mac" is checked. If it is "Scaled t oMatch iPad", then it works well. Xcode 16.1 macOS 15.1 struct DocumentGroupTestApp: App { var body: some Scene { DocumentGroup(newDocument: WritingAppDocument()) { file in TestView() // it is empty when it gets opened. It does not work if the option "Optimize for Mac" is checked. If it is scale iPad, then it works. } } } struct TestView: View { var body: some View { Text("Hello, World!") } }

In iOS18 the user can change their Home Screen customization to choose either light, dark, or tinted. If they choose tinted the widgets are rendered using the "accented" rendering mode and without a background. Is there some way to override so that the tinted mode is ignore completely and the widgets render as full color? I know about WidgetAccentedRenderingMode (https://developer.apple.com/documentation/widgetkit/widgetaccentedrenderingmode) but that's only for images, not the whole control and doesn't help with the background also being removed in the tinted mode.

I have this code to make ARVR Stereo View To Be Used in VR Box Or Google Cardboard, it uses iOS 18 New RealityView but it is not Act as an AR but rather Static VR on a Camera background so as I move the iPhone the cube move with it and that's not suppose to happen if its Anchored in a plane or to world coordinate. import SwiftUI import RealityKit struct ContentView : View { let anchor1 = AnchorEntity(.camera) let anchor2 = AnchorEntity(.camera) var body: some View { HStack (spacing: 0){ MainView(anchor: anchor1) MainView(anchor: anchor2) } .background(.black) } } struct MainView : View { @State var anchor = AnchorEntity() var body: some View { RealityView { content in content.camera = .spatialTracking let item = ModelEntity(mesh: .generateBox(size: 0.25), materials: [SimpleMaterial()]) anchor.addChild(item) content.add(anchor) anchor.position.z = -1.0 anchor.orientation = .init(angle: .pi/4, axis:[0,1,1]) } } } the thing is if I remove .camera like this let anchor1 = AnchorEntity() let anchor2 = AnchorEntity() It would work as AR Anchored to world coordinates but on the other hand is does not work but on the left view only not both views Meanwhile this was so easy before RealityView and SwiftUI by cloning the view like in ARSCNView Example : import UIKit import ARKit class ViewController: UIViewController, ARSCNViewDelegate, ARSessionDelegate { //create Any Two ARSCNView's in Story board // and link each to the next (dont mind dimensions) @IBOutlet var sceneView: ARSCNView! @IBOutlet var sceneView2: ARSCNView! override func viewDidLoad() { super.viewDidLoad() // Do any additional setup after loading the view. sceneView.delegate = self sceneView.session.delegate = self // Create SceneKit box let box = SCNBox(width: 0.1, height: 0.1, length: 0.1, chamferRadius: 0.01) let item = SCNNode(geometry: box) item.geometry?.materials.first?.diffuse.contents = UIColor.green item.position = SCNVector3(0.0, 0.0, -1.0) item.orientation = SCNVector4(0, 1, 1, .pi/4.0) // retrieve the ship node sceneView.scene.rootNode.addChildNode(item) } override func viewDidLayoutSubviews() // To Do Add the 4 Buttons { // Stop Screen Dimming or Closing While The App Is Running UIApplication.shared.isIdleTimerDisabled = true let screen: CGRect = UIScreen.main.bounds let topPadding: CGFloat = self.view.safeAreaInsets.top let bottomPadding: CGFloat = self.view.safeAreaInsets.bottom let leftPadding: CGFloat = self.view.safeAreaInsets.left let rightPadding: CGFloat = self.view.safeAreaInsets.right let safeArea: CGRect = CGRect(x: leftPadding, y: topPadding, width: screen.size.width - leftPadding - rightPadding, height: screen.size.height - topPadding - bottomPadding) DispatchQueue.main.async { if self.sceneView != nil { self.sceneView.frame = CGRect(x: safeArea.size.width * 0 + safeArea.origin.x, y: safeArea.size.height * 0 + safeArea.origin.y, width: safeArea.size.width * 0.5, height: safeArea.size.height * 1) } if self.sceneView2 != nil { self.sceneView2.frame = CGRect(x: safeArea.size.width * 0.5 + safeArea.origin.x, y: safeArea.size.height * 0 + safeArea.origin.y, width: safeArea.size.width * 0.5, height: safeArea.size.height * 1) } } } override func viewDidAppear(_ animated: Bool) { super.viewDidAppear(animated) let configuration = ARWorldTrackingConfiguration() sceneView.session.run(configuration) sceneView2.scene = sceneView.scene sceneView2.session = sceneView.session } } And here is the video for it

I have a Map within a SwiftUI app that has the selection parameter set to an optional MapSelection. I need to be able to select MapFeatures which works as expected as well as MKMapItems which are added to the map. The MKMapItems are not selectable. Is it possible to make it such that the Map allows the user to select MKMapItems as well as MapFeatures?

Is it possible to get a MapFeature from an MKMapItem?

Hello, I'm seeing a strange error on another user's device where the SwiftUI file importer doesn't do anything at all. When selecting multiple files and hitting "open", the importer just freezes. Here's a video showing the problem: https://streamable.com/u5grgy I'm unable to replicate on my own device, so I'm not sure what could be going on. I have startAccessingSecurityScopedResource and stopAccessingSecurityResource everywhere I access a file from fileImporter as well.

I have a Split View with the sidebar, content, and detail. Everything is working, but when I select on a NavigationLink in my detail view, the back button is seen next to the title above the content view. I want that back button to be displayed in the top bar on the left side of the detail view. I was expecting it to do this automatically, but I must be missing something. This is where I want it to appear. This is where it appears. I made a simplified version of my code, because it would be too much to post but this has the same behavior. struct TestView: View { enum SidebarSelections { case cycles } @State private var sidebarSelection: SidebarSelections = .cycles var body: some View { NavigationSplitView(sidebar: { List(selection: $sidebarSelection, content: { Label("Cycles", systemImage: "calendar") .tag(SidebarSelections.cycles) }) }, content: { switch sidebarSelection { case .cycles: NavigationStack { List { // Displayed in Content NavigationLink("Cycle link", destination: { // Displayed in the Detail NavigationStack { List { NavigationLink("Detail Link", destination: { Text("More details") }) } } }) } } } }, detail: { ContentUnavailableView("Nothing to see here", systemImage: "cloud") }) } } Is what I want to do possible? Here is a Stack Overflow post that had it working at one point.

I have an issue using RealityView to show two screens of AR, while I did succeed to make it as a non AR but now my code not working. Also it is working using Storyboard and Swift with SceneKit, so why it is not working in RealityView? import SwiftUI import RealityKit struct ContentView : View { var body: some View { HStack (spacing: 0){ MainView() MainView() } .background(.black) } } struct MainView : View { @State var anchor = AnchorEntity() var body: some View { RealityView { content in let item = ModelEntity(mesh: .generateBox(size: 0.2), materials: [SimpleMaterial()]) content.camera = .spatialTracking anchor.addChild(item) anchor.position = [0.0, 0.0, -1.0] anchor.orientation = .init(angle: .pi/4, axis:[0,1,1]) // Add the horizontal plane anchor to the scene content.add(anchor) } } }

I am creating a UIKit application but that contains SwiftUI Views embedded using the hostingcontroller. I have a particular approach for it..but it requires instantiating a swiftUI view, creating a hostingcontroller object from it and storing a reference to it. So that later If I wanted to update the view, I can simply get the reference back and update the swiftUI view using it. I wanted to understand what does apple recommends on this. Can we store a swiftUI instance? Does it cause any issue or it is okay to do so?

I was hoping for an update of SwiftData which adopted the use of shared and public CloudKit containers, in the same way it does for the private CloudKit container. So firstly, a big request to any Apple devs reading, for this to be a thing! Secondly, what would be a sensible way of adding a shared container in CloudKit to an existing app that is already using SwiftData? Would it be possible to use the new DataStore method to manage CloudKit syncing with a public or shared container?

You'll have to forgive me, I am still pretty new to Swift, but I'm really struggling to figure out what I'm doing wrong or how I can fix it. I'm working on an app that generates an image from some views and then exports that image, but it always returns this very vague error: The operation couldn’t be completed. (SwiftUI.FileExportOperation.Error error 0.) Here's most of the program: import SwiftUI import UniformTypeIdentifiers struct ContentView: View { @State private var backgroundColor = Color.black @State private var fileExporterIsPresented = false @State private var image: NSImage? @State private var fileExporterErrorAlertIsPresented = false @State private var fileExporterErrorDescription: String? var body: some View { let wallpaper = Rectangle() .foregroundStyle(backgroundColor) .aspectRatio(16 / 9, contentMode: .fit) VStack { wallpaper .clipShape(.rect(cornerRadius: 10)) .overlay { RoundedRectangle(cornerRadius: 10) .strokeBorder(.separator, lineWidth: 5) } ColorPicker("Background Color", selection: $backgroundColor, supportsOpacity: false) Button("Generate Wallpaper") { let renderer = ImageRenderer(content: wallpaper.frame(width: 3840, height: 2160)) image = renderer.nsImage fileExporterIsPresented = true } .fileExporter( isPresented: $fileExporterIsPresented, item: image, contentTypes: [UTType.heic, UTType.png] ) { result in if case .failure(let error) = result { fileExporterErrorDescription = error.localizedDescription fileExporterErrorAlertIsPresented = true } } .alert("File Exporter Failure", isPresented: $fileExporterErrorAlertIsPresented, actions: { Button("OK") {} }, message: { if let fileExporterErrorDescription { Text(fileExporterErrorDescription) } }) .dialogSeverity(.critical) } .padding() } } #Preview { ContentView() }

Working on a macOS app. I need to display user-added images as a background to the view, with all of: Tiling (auto repeat in both axes) Scaling (user-configured scale of the image) Offset (user-configured offset) I've been able to achieve scaling and offset with: Image(nsImage: nsImage) .scaleEffect(mapImage.scale) .offset(mapImage.offset) .frame(width: scaledImageSize.width, height: scaledImageSize.height) But when I try to incorporate tiling into that with .resizable(resizingMode: .tile) everything breaks. Is there a way to position the "anchor" of an image, scale it, and tile it in both axes to fill a container view?

Hello team, We recently found a EXC_BAD_ACCESS crash when using UIHostingControllers on a SPM local Package in our application. This is happening from time to time when we run the app on simulators using Debug configurations. Also, this issue is consistent when we run application tests, there is something weird that we found after making a research... If we disable app test target and only keep packages tests, the crash is not happening, but as soon as we re-enable the app test target from the test suite the crash returns. This is the full error message: Thread 1: EXC_BAD_ACCESS (code=1, address=0xbad4017) A bad access to memory terminated the process. Is this s known issue? We've been performing explorations for some days and couldn't find any real solution for this. A basic call on UIHostingController inside of a SPM local Package is enough to make the app crash, nothing custom being done: UIHostingController(rootView: MyView())
