When you try to reset settings through the Apple Vision Pro simulator (VisionOS 2.4) you get an error "Preferences quit unexpectedly". Bug report: FB17666053

Hello, I'm encountering a runtime crash when building my visionOS app with Xcode 16.3 for visionOS 2.5. Our existing AppStore/Testflight app is also instantly crashing on visionOS 2.5 when opened but works fine on e.g visionOS 2.4. The app builds successfully but crashes on launch with this symbol lookup error (slightly adjusted because the forum complained regarding sensitive data): Symbol not found: _$sSo22CLLocationCoordinate2DVSE12CoreLocationMc Referenced from: <XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX> /private/var/containers/Bundle/Application/XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX/MyApp.app/MyApp.debug.dylib Expected in: <XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX> /usr/lib/swift/libswiftCoreLocation.dylib dyld config: DYLD_LIBRARY_PATH=/usr/lib/system/introspection DYLD_INSERT_LIBRARIES=/usr/lib/libLogRedirect.dylib:/usr/lib/libBacktraceRecording.dylib:/usr/lib/libMainThreadChecker.dylib:/System/Library/PrivateFrameworks/GPUToolsCapture.framework/GPUToolsCapture:/usr/lib/libViewDebuggerSupport.dylib I've already implemented my own Codable conformance for CLLocationCoordinate2D: extension CLLocationCoordinate2D: Codable { // implementation details... } This worked fine on previous visionOS/Xcode versions. Has anyone encountered this issue or found a solution? System details: macOS version: 15.3.2 Xcode version: 16.3 visionOS target: 2.5 Thank you!

Dear App Review Team, I am writing to express deep concern over the repeated and prolonged delays the app is facing during the App Review process. Once again, a recent build—submitted on May 12—has been stuck in the "In Review" state for over a week. I have been informed that, as has become routine, the submission has been escalated to the App Review Board without any clear timeline or communication. This is not an isolated incident. Nearly every feature update submitted is referred to the board, resulting in unpredictable, weeks-long delays that severely disrupt the development and release cycle. These escalations consistently happen without clear reasoning, and without any proactive outreach or follow-up from the review team. The app is currently one of the highest-performing indie titles on the visionOS App Store, and I am committed to delivering the highest quality experience for users on Apple platforms. However, the current review process is making it increasingly difficult to operate responsibly or efficiently. The lack of transparency and responsiveness is not only frustrating—it is actively harming product stability, user trust, and overall business health. I am requesting immediate attention and action on this matter. Specifically: Clear communication on the status of the current review. An explanation as to why the updates are repeatedly escalated to the board. A path toward a more predictable and professional review process moving forward. I am fully committed to maintaining a positive and productive relationship with Apple, but the current pattern is unsustainable. App ID: 6737148404

I have an attachment anchored to the head motion, and I put a WKWebView as the attachment. When I try to interact with the web view, the app crashes with the following errors: *** Assertion failure in -[UIGestureGraphEdge initWithLabel:sourceNode:targetNode:directed:], UIGestureGraphEdge.m:28 *** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'Invalid parameter not satisfying: targetNode' *** First throw call stack: (0x18e529340 0x185845e80 0x192c2283c 0x2433874d4 0x243382ebc 0x2433969a8 0x24339635c 0x243396088 0x243907760 0x2438e4c94 0x24397b488 0x24397e28c 0x243976a20 0x242d7fdc0 0x2437e6e88 0x2437e6254 0x18e4922ec 0x18e492230 0x18e49196c 0x18e48bf3c 0x18e48b798 0x1d3156090 0x2438c8530 0x2438cd240 0x19fde0d58 0x19fde0a64 0x19fa5890c 0x10503b0bc 0x10503b230 0x2572247b8) libc++abi: terminating due to uncaught exception of type NSException *** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'Invalid parameter not satisfying: targetNode' *** First throw call stack: (0x18e529340 0x185845e80 0x192c2283c 0x2433874d4 0x243382ebc 0x2433969a8 0x24339635c 0x243396088 0x243907760 0x2438e4c94 0x24397b488 0x24397e28c 0x243976a20 0x242d7fdc0 0x2437e6e88 0x2437e6254 0x18e4922ec 0x18e492230 0x18e49196c 0x18e48bf3c 0x18e48b798 0x1d3156090 0x2438c8530 0x2438cd240 0x19fde0d58 0x19fde0a64 0x19fa5890c 0x10503b0bc 0x10503b230 0x2572247b8) terminating due to uncaught exception of type NSException Message from debugger: killed This is the code for the RealityView struct ImmersiveView: View { @Environment(AppModel.self) private var appModel var body: some View { RealityView { content, attachments in let anchor = AnchorEntity(AnchoringComponent.Target.head) if let sceneAttachment = attachments.entity(for: "test") { sceneAttachment.position = SIMD3<Float>(0,0,-3.5) anchor.addChild(sceneAttachment) } content.add(anchor) } attachments: { Attachment(id: "test") { WebViewWrapper(webView: appModel.webViewModel.webView) } } } } This is the appModel: import SwiftUI import WebKit /// Maintains app-wide state @MainActor @Observable class AppModel { let immersiveSpaceID = "ImmersiveSpace" enum ImmersiveSpaceState { case closed case inTransition case open } var immersiveSpaceState = ImmersiveSpaceState.closed public let webViewModel = WebViewModel() } @MainActor final class WebViewModel { let webView = WKWebView() func loadViz(_ addressStr: String) { guard let url = URL(string: addressStr) else { return } webView.load(URLRequest(url: url)) } } struct WebViewWrapper: UIViewRepresentable { let webView: WKWebView func makeUIView(context: Context) -> WKWebView { webView } func updateUIView(_ uiView: WKWebView, context: Context) { } } and finally the ContentView where I added a button to load the webpage: struct ContentView: View { @Environment(AppModel.self) private var appModel var body: some View { VStack { ToggleImmersiveSpaceButton() Button("Go") { appModel.webViewModel.loadViz("http://apple.com") } } .padding() } }

Hi guys, In visionOS, when using a ZStack decorated with .glassBackgroundEffect(), you can see the 3D glass background from the front, but when viewed from the side, the view appears to have no thickness. However, I noticed that in an app built by Apple, when viewing a glass background view from the side, it appears to have thickness. I tried adding .frame(depth:) to a glass background view, but it appears as two separate layers spaced by the depth value. My question is: Is there a view modifier that adds visual thickness to a glass background view, as shown in the picture? Or, if not, how should I write a custom view modifier to achieve this effect? Thanks!

I am trying to create an object in immersive space that is partially transparent (~50% opacity). I have implemented this in a few different ways including creating a model entity and setting its opacity component to 0.5, and creating a custom material with blending set to a transparent opacity of 0.5. These both work partially, as they behaved as intended for many cases, but seemingly randomly would act like occlusion material and block any other immersive content behind them, showing the real world instead. Some notes: I am using RealityKit to render the semi-transparent object and an opaque object that is behind the semi-transparent object. I am using VisionOS 2.1, and am updating the location of the semi-transparent object often. Both objects are ModelEntities. I would appreciate any guidance on how to implement this. Please let me know if there are any other questions.

Here is the sample project from apple of Object Tracking. https://developer.apple.com/documentation/visionOS/exploring_object_tracking_with_arkit can we improve it tracking accuracy and tracking when object is moving little faster, so the 3d object that draw still follow it and make it more accurate.

In the AVP project, a selector pops up, only wanting to filter spatial videos. When selecting the material of one of the spatial videos, the selection result returns empty. How can we obtain the video selected by the user and get the path and the URL of the file The code is as follows： PhotosPicker(selection: $selectedItem, matching: .videos) { Text("Choose a spatial photo or video") } func loadTransferable(from imageSelection: PhotosPickerItem) -> Progress { return imageSelection.loadTransferable(type: URL.self) { result in DispatchQueue.main.async { // guard imageSelection == self.imageSelection else { return } print("加载成功的图片集合:(result)") switch result { case .success(let url?): self.selectSpatialVideoURL = url print("获取视频链接:(url)") case .success(nil): break // Handle the success case with an empty value. case .failure(let error): print("spatial错误：(error)") // Handle the failure case with the provided error. } } } }

How do you call the effect where the edges around the central image gradually become transparent? This effect is also seen when viewing immersive mode of spatial photos in Vision Pro. How can I achieve this effect using SwiftUI or ShaderGraph? I want to use this effect when displaying images in my app.

Using Reality Composer Pro 2.0, I created a simple shader graph that displays a texture on an unlit surface: On visionOS 2 beta, I can successfully use ShaderGraphMaterial(named:from:in:) to load that shader graph material and assign it to a model entity. However, on visionOS 1.2 and earlier, either in Simulator or on the device, ShaderGraphMaterial(named:from:in:) fails and I see the following logged to the console: If, using Reality Composer Pro 1.0, I experimentally open the same project and delete and recreate exactly the same nodes above, then ShaderGraphMaterial(named:from:in:) works as expected on visionOS 1.2. Is it a known issue that Reality Composer 2 can't be used with visionOS 1? Is this intentional behavior? I've submitted feedback as FB14828873, including a sample project and repro steps. If possible, I would appreciate guidance from an Apple engineer, like "This is a known issue for [list of node types]" or "Reality Composer Pro 2 is not supported for visionOS 1 development, please refer to [documentation]" or "We recommend [workaround]." Thank you.

I have an AVP app thats already been approved that requires VisionOS 2.4 for the Background Assets feature. The project is set to 2.4 min, but when doing test flights folks that did not have 2.4 did not receive a warning or anything they just get a download error and then think its a bug. Is there a way to only allow devices with 2.4 to download a app? Im new to Apple dev but I'd assume this is standard. Thanks!

Hello! I’m familiar with the discussion on “Sending messages to the scene”, and I’ve successfully used that code. However, I have several instances of the same model in my scene. Is it possible to make only one specific model respond to a notification? For example, can I pass something like RealityKit.NotificationTrigger.SourceEntity in userInfo or use another method to target just one instance?

Hi everyone, I'm developing a visionOS app that allows users to download large video files (similar to a movie download experience, with each file being around 10 GB). I've successfully implemented the core video download functionality using URLSession, and everything works as expected while the app is active. Now, I’m looking to support background downloading. Specifically, I want users to be able to start a download and then leave the app (e.g., switch apps or return to the home screen) while the download continues in the background. Additionally, I’d like to confirm a specific scenario: If the user starts a download, then removes the headset (keeping the device turned on and connected to power), will the download continue in the background? Or does visionOS suspend the app or downloads in this case? I’m considering using a background URLSessionConfiguration (as done in iOS/macOS) to enable this behavior, but I’m not sure if it behaves the same way on visionOS or if there are special limitations or best practices when handling large downloads on this platform. Any insights or official guidance would be greatly appreciated! Thanks!

Seeing this magical sand table, the unfolding and folding effects are similar to spreading out cards, which is very interesting. But I don't know how to achieve it. I want to see if there are any ways to achieve this effect and give some ideas. May I ask if this effect can be achieved under the existing API

I noticed that when I drag the menu window in an Immersive View, the entities behind it becomes semi-transparent, and the boundary between virtual and real-world objects is very pronounced. May I ask how does VisionOS implement this effect? Is there any API or technique I can use in my own code to enable the same semi-transparent overlay - even when I am not dragging the menu window?

I encountered some issues while developing a Vision Pro program using Unity. After binding an ARAnchor to a game object, I overlapped the virtual game object with a real-world cup. However, when I moved around with the Vision Pro on, the virtual game object shifted, causing the real-world cup and the virtual object to no longer coincide. Is there a way to solve this?

I’ve been having some issues removing anchors. I can add anchors with no issue. They will be there the next time I run the scene. I can also get updates when ARKit sends them. I can remove anchors, but not all the time. The method I’m using is to call removeAnchor() on the data provider. worldTracking.removeAnchor(forID: uuid) // Yes, I have also tried `removeAnchor(_ worldAnchor: WorldAnchor)` This works if there are more than one anchor in a scene. When I’m down to one remaining anchor, I can remove it. It seems to succeed (does not raise an error) but the next time I run the scene the removed anchor is back. This only happens when there is only one remaining anchor. do { // This always run, but it doesn't seem to "save" the removal when there is only one anchor left. try await worldTracking.removeAnchor(forID: uuid) } catch { // I have never seen this block fire! print("Failed to remove world anchor \(uuid) with error: \(error).") } I posted a video on my website if you want to see it happening. https://stepinto.vision/labs/lab-051-issues-with-world-tracking/ Here is the full code. Can you see if I’m doing something wrong? Is this a bug? struct Lab051: View { @State var session = ARKitSession() @State var worldTracking = WorldTrackingProvider() @State var worldAnchorEntities: [UUID: Entity] = [:] @State var placement = Entity() @State var subject : ModelEntity = { let subject = ModelEntity( mesh: .generateSphere(radius: 0.06), materials: [SimpleMaterial(color: .stepRed, isMetallic: false)]) subject.setPosition([0, 0, 0], relativeTo: nil) let collision = CollisionComponent(shapes: [.generateSphere(radius: 0.06)]) let input = InputTargetComponent() subject.components.set([collision, input]) return subject }() var body: some View { RealityView { content in guard let scene = try? await Entity(named: "WorldTracking", in: realityKitContentBundle) else { return } content.add(scene) if let placementEntity = scene.findEntity(named: "PlacementPreview") { placement = placementEntity } } update: { content in for (_, entity) in worldAnchorEntities { if !content.entities.contains(entity) { content.add(entity) } } } .modifier(DragGestureImproved()) .gesture(tapGesture) .task { try! await setupAndRunWorldTracking() } } var tapGesture: some Gesture { TapGesture() .targetedToAnyEntity() .onEnded { value in if value.entity.name == "PlacementPreview" { // If we tapped the placement preview cube, create an anchor Task { let anchor = WorldAnchor(originFromAnchorTransform: value.entity.transformMatrix(relativeTo: nil)) try await worldTracking.addAnchor(anchor) } } else { Task { // Get the UUID we stored on the entity let uuid = UUID(uuidString: value.entity.name) ?? UUID() do { try await worldTracking.removeAnchor(forID: uuid) } catch { print("Failed to remove world anchor \(uuid) with error: \(error).") } } } } } func setupAndRunWorldTracking() async throws { if WorldTrackingProvider.isSupported { do { try await session.run([worldTracking]) for await update in worldTracking.anchorUpdates { switch update.event { case .added: let subjectClone = subject.clone(recursive: true) subjectClone.isEnabled = true subjectClone.name = update.anchor.id.uuidString subjectClone.transform = Transform(matrix: update.anchor.originFromAnchorTransform) worldAnchorEntities[update.anchor.id] = subjectClone print("🟢 Anchor added \(update.anchor.id)") case .updated: guard let entity = worldAnchorEntities[update.anchor.id] else { print("No entity found to update for anchor \(update.anchor.id)") return } entity.transform = Transform(matrix: update.anchor.originFromAnchorTransform) print("🔵 Anchor updated \(update.anchor.id)") case .removed: worldAnchorEntities[update.anchor.id]?.removeFromParent() worldAnchorEntities.removeValue(forKey: update.anchor.id) print("🔴 Anchor removed \(update.anchor.id)") if let remainingAnchors = await worldTracking.allAnchors { print("Remaining Anchors: \(remainingAnchors.count)") } } } } catch { print("ARKit session error \(error)") } } } }

Hi, I'm playing now with hand tracking. I want to get position of hand inside a system update function. I was not sure if transform I'm getting from hand attached AnchorEntity (with trackingMode: .predicted) would give same results as handAnchors(at:) from hand tracking provider, so I started to read them both and compare. For handAnchors i tried using context.scene.timebase.sourceTimebase!.sourceClock!.time.seconds and CACurrentMediaTime() as timestamp source. They seem to use exactly same clock, so that doesn't matter, but: for some reason update handler is always called twice with same context.deltaTime, but first time the query finds 0 entities, second time it finds them all. The query is the standard EntityQuery(where: .has(MyComponent.self)) and in update (matching: Self.query, updatingSystemWhen: .rendering). Here's part of logs: System update called, entity count: 0, dt: 0.01000458374619484, absTime: 4654.222593541 System update called, entity count: 11, dt: 0.01000458374619484, absTime: 4654.22262525 System update called, entity count: 0, dt: 0.009999999776482582, absTime: 4654.249390875 System update called, entity count: 11, dt: 0.009999999776482582, absTime: 4654.249425 accounting for the double update calling I started to calculate time delta of absolute time between calls and they're most of the time much bigger, or much smaller than advertised by system's context.deltaTime, only sometimes they kind of match, for example: system: (dt: 0.01000458374619484) scene : (dt: 0.021419291667371) (absTime: 4654.222628125001) and the very next call system: (dt: 0.010009 166784584522) scene : (dt: 0.0013097083328830195) (absTime: 4654.223937833334) but sometimes system: (dt: 0.009999999776482582) scene : (dt: 0.009 112249999816413) (absTime: 4654.351299 166668) Shouldn't those be more or less equal, or am I missing something? In the end it seems that getting hand position from AnchorEntity and with handAnchors(at:) gives kind of same results, but at different time points, so I'd love to understand what's the correct way to use them and why time flows differently :). --Edit-- P.S. Had to put spaces everywhere in logs between "9" and "1", otherwise post was blocked due to "sensitive content" :D

Environment Xcode: 16.2 VisionOS SDK 2.4 Swift 6.1 Targets: Apple Vision Pro (immersive space) Frameworks: ARKit, RealityKit, SwiftUI What I’m Trying to Do I have a view-model class PlacementManager that holds two AR providers: private var worldTracking: WorldTrackingProvider private var planeDetection: PlaneDetectionProvider I want to dynamically replace these providers in a setEnvironment(_:) method (so I can save/clear a JSON scene and restart ARKit). What’s Happening If I declare them as : private let worldTracking = WorldTrackingProvider() private let planeDetection = PlaneDetectionProvider() I get compile-errors when I later do: self.worldTracking = newWorldTracking // Cannot assign to property: 'worldTracking' is a 'let' constant If I change them to un-initialized vars: private var worldTracking: WorldTrackingProvider private var planeDetection: PlaneDetectionProvider then in my init() I get: self used in property access 'worldTracking' before all stored properties are initialized Code snipet @Observable final class PlacementManager : ObservableObject { private var worldTracking: WorldTrackingProvider private var planeDetection: PlaneDetectionProvider // … other props … @MainActor init() { // error: self.worldTracking used before init… planeAnchorHandler = PlaneAnchorHandler(rootEntity: root) persistenceManager = PersistenceManager( worldTracking: worldTracking, rootEntity: root ) // … } @MainActor func setEnvironment(env: Environnement) async { let newWorldTracking = WorldTrackingProvider() let newPlaneDetection = PlaneDetectionProvider() try await appState!.arkitSession.run( [ newWorldTracking, newPlaneDetection ] ) self.worldTracking = newWorldTracking self.planeDetection = newPlaneDetection // … } } What I’ve Tried Giving them default values at declaration (= WorldTrackingProvider()) Initializing them at the top of init() before any use Passing the new providers into arkitSession.run(...) My Question What is the recommended Swift-style pattern to declare and reassign these ARKit provider properties so that: They’re fully initialized before use in init(), and I can swap them out later in setEnvironment(...) without compiler errors? Any pointers (or links to forum threads / docs) would be greatly appreciated!

I have a simple example to demonstrate... struct MyView: View { var body: some View { Text("WOW") } } struct MyOtherView: View { var body: some View { NavigationStack { Text("WOW") } } } On VisionOS, MyOtherView has a glass background effect that cannot be disabled. glassBackgroundEffect(displayMode: .never) .background(.clear), .foregroundColor(.clear), none of them work. I then resorted to the SwiftUIIntrospect package to try set .clear on various child objects of the NavigationStack but nothing is working. I am in control of my own glass containers. I have a couple with space between them, but with the NavigationStack it sets a background behind both of them ruining the effect. This is what MyOtherView renders as: I'm looking for it to be completely transparent except the text. Like the below layout. For now I will have to roll my own navigation.
