Hi I am using this function to create collisions in my scene from Apple Developer Video I found. func processReconstructionUpdates() async { for await update in sceneReconstruction.anchorUpdates { let meshAnchor = update.anchor guard let shape = try? await ShapeResource.generateStaticMesh(from: meshAnchor) else {continue} switch update.event { case .added: let entity = ModelEntity() entity.transform = Transform(matrix: meshAnchor.originFromAnchorTransform) entity.collision = CollisionComponent(shapes: [shape], isStatic: true) entity.physicsBody = PhysicsBodyComponent() entity.components.set(InputTargetComponent()) meshEntities[meshAnchor.id] = entity contentEntity.addChild(entity) case .updated: guard let entity = meshEntities[meshAnchor.id] else { fatalError("...") } entity.transform = Transform(matrix: meshAnchor.originFromAnchorTransform) entity.collision?.shapes = [shape] case .removed: meshEntities[meshAnchor.id]?.removeFromParent() meshEntities.removeValue(forKey: meshAnchor.id) } } } The code works great. In the same immersive space I am opening a window: var body: some View { RealityView { content in // some other code here openWindow(id: "mywindowidhere") // some other code here } } The window opens in front of me, but I am not able to click or even hover on the buttons. At first I did not know why that was happening. But then I turned on pointer control and found out that the pointer is actually colliding with the wall. (the window is kinda inside the wall). That is why the pointer never reaches the window and the button never gets clicked. I initially thought this was a layering issue, but I was not able to find any documentation related to this. Is this a known issue and is there any way to fix this? Or I am doing anything wrong on my side?

I installed Beta 4 of VisionOS 2 and now whenever I take the headset off nothing works after putting it back on except passthrough until the device is rebooted. This is somewhat inconvenient. I've raised it as a feedback but wondering if this is something others have noticed.

I'm working on a multi-platform app (macOS and visionOS for now). In these early stages it’s easier to target the Mac, but I started with a visionOS project. One of the things the template creates is a RealityKitContent package dependency. I can target macOS 14.5 in Xcode, but when it goes to build the RealiityKitContent, I get this error: error: Building for 'macosx', but '14.0' must be >= '15.0' [macosx] info: realitytool ["/Applications/Xcode-beta.app/Contents/Developer/usr/bin/realitytool" "compile" "--platform" "macosx" "--deployment-target" "14.0" … Unfortunately, I'm unwilling to update this machine to macOS 15, as it's too risky. Running macOS 15 in a VM is not possible (Apple Silicon). This strikes me as a bug, or severe shortcoming, of realitytool. This was introduced with visionOS 1.0, and should be able to target macOS < 15. It's not really reasonable to use Xcode 15, since soon enough Apple will require I build with Xcode 16 for submission to the App Store. Is this a bug, or intentional?

Hi, it seems the accuracy of the true depth map is far worse when streaming (using iPhone 13) with similar artefacts as shown in this post: https://forums.developer.apple.com/forums/thread/694147. However when taking static photos, the quality is pretty good, despite resolutions being the same (480x640). This is for an object <1m distance. Does anyone know how I can improve the accuracy when streaming?

Does visionOS 2 still prompt the user with a permission alert when a full immersive space is presented? In visionOS 1, the first time an app presented an immersive space, the user was prompted with an alert to grant permission. openImmersiveSpace would return an error code if the user opted not to grant permission. In visionOS 1, it was important to handle this case correctly. In visionOS 1, the Settings > Developer menu had an option to reset the immersive user's space permission prompting state so developers could test this interaction flow. In visionOS 2, I no longer see the full immersive space permissions alert. I can't remember if I saw it once, the first time visionOS 2.0 beta was installed, or if I never saw it at all. The Settings > Developer menu no longer has an option to reset the permission prompting state. I can't find any way to test the interaction flow in my app to make sure that it will work correctly for users. Does visionOS 2 no longer ask for full immersive space permission at all? I can't find this change documented anywhere. If visionOS 2 does prompt the user for permission, is there any way to reproduce and test this interaction flow so I can make sure my app handles it correctly? Thanks for taking the time to answer this question.

I have recently developed an interest in the shader effects commonly found in Apple's UI and have been studying them. Additionally, as I own a Vision Pro, I have a strong desire to understand LowLevelMesh and am currently analyzing the sample code after watching the related session. The part where I am completely stuck and unable to understand is the initializer section of CurveExtruder. /// Initializes the `CurveExtruder` with the shape to sweep along the curve. /// /// - Parameters: /// - shape: The 2D shape to sweep along the curve. init(shape: [SIMD2<Float>]) { self.shape = shape // Compute topology // // Triangle fan lists each vertex in `shape` once for each ring, except for vertex `0` of `shape` which // is listed twice. Plus one extra index for the end-index (0xFFFFFFFF). let indexCountPerFan = 2 * (shape.count + 1) + 1 var topology: [UInt32] = [] topology.reserveCapacity(indexCountPerFan) // Build triangle fan. for vertexIndex in shape.indices.reversed() { topology.append(UInt32(vertexIndex)) topology.append(UInt32(shape.count + vertexIndex)) } // Wrap around to the first vertex. topology.append(UInt32(shape.count - 1)) topology.append(UInt32(2 * shape.count - 1)) // Add end-index. topology.append(UInt32.max) assert(topology.count == indexCountPerFan) I have tried to understand why the capacity reserved for the topology array is 2 * (shape.count + 1) + 1, but I am struggling to figure it out. I do not understand the principle behind the order in which vertexIndex is added to the topology. The confusion is even greater because, while the comment mentions trianglefan, the actual creation of the LowLevelMesh.Part object uses the topology: .triangleStrip argument. (Did I misunderstand? I know that the topology option includes triangle, but this uses duplicated vertices.) I am feeling very stuck. It's hard to find answers even through search options or LLMs. Maybe this requires specialized knowledge in computer graphics, which makes me feel embarrassed to ask. However, personally, I have tried various directions without external help but still cannot find a clear path, so I am desperately seeking assistance! P.S. As Korean is my primary language, I apologize in advance if there are any awkward or rude expressions.

I am using the Xcode visionOS debugging tool to visualize the bounds of all the containers, but it shows my Entity is inside the Volume. Then why does it get clipped? Is there something wrong with the debugger, or am I missing something? import SwiftUI @main struct RealityViewAttachmentApp: App { var body: some Scene { WindowGroup { ContentView() } .windowStyle(.volumetric) .defaultSize(Size3D(width: 1, height: 1, depth: 1), in: .meters) } } import SwiftUI import RealityKit import RealityKitContent struct ContentView: View { var body: some View { RealityView { content, attachments in if let earth = try? await Entity(named: "Scene", in: realityKitContentBundle) { content.add(earth) if let earthAttachment = attachments.entity(for: "earth_label") { earthAttachment.position = [0, -0.15, 0] earth.addChild(earthAttachment) } if let textAttachment = attachments.entity(for: "text_label") { textAttachment.position = [-0.5, 0, 0] earth.addChild(textAttachment) } } } attachments: { Attachment(id: "earth_label") { Text("Earth") } Attachment(id: "text_label") { VStack { Text("This is just an example") .font(.title) .padding(.bottom, 20) Text("This is just some random content") .font(.caption) } .frame(minWidth: 100, maxWidth: 300, minHeight: 100, maxHeight: 300) .glassBackgroundEffect() } } } }

My app has a window and a volume. I am trying to display the volume on the right side of the window. I know .defaultWindowPlacement can achieve that, but I want more control over the exact position of my volume in relation to my window. I need the volume to move as I move the window so that it always stays in the same position relative to the window. I think I need a way to track the positions of both the window and the volume. If this can be achieved without immersive space, it would be great. If not, how do I do that in immersive space? Current code: import SwiftUI @main struct tiktokForSpacialModelingApp: App { @State private var appModel: AppModel = AppModel() var body: some Scene { WindowGroup(id: appModel.launchWindowID) { LaunchWindow() .environment(appModel) } .windowResizability(.contentSize) WindowGroup(id: appModel.mainViewWindowID) { MainView() .frame(minWidth: 500, maxWidth: 600, minHeight: 1200, maxHeight: 1440) .environment(appModel) } .windowResizability(.contentSize) WindowGroup(id: appModel.postVolumeID) { let initialSize = Size3D(width: 900, height: 500, depth: 900) PostVolume() .frame(minWidth: initialSize.width, maxWidth: initialSize.width * 4, minHeight: initialSize.height, maxHeight: initialSize.height * 4) .frame(minDepth: initialSize.depth, maxDepth: initialSize.depth * 4) } .windowStyle(.volumetric) .windowResizability(.contentSize) .defaultWindowPlacement { content, context in // Get WindowProxy from context based on id if let mainViewWindow = context.windows.first(where: { $0.id == appModel.mainViewWindowID }) { return WindowPlacement(.trailing(mainViewWindow)) } else { return WindowPlacement() } } ImmersiveSpace(id: appModel.immersiveSpaceID) { ImmersiveView() .onAppear { appModel.immersiveSpaceState = .open } .onDisappear { appModel.immersiveSpaceState = .closed } } .immersionStyle(selection: .constant(.progressive), in: .progressive) } }

I am trying to add joints via code in my visionOS app. My scenario requires me to combine models from Reality Composer Pro with entities and components from code to generate the dynamic result. I am using the latest visionOS beta and Xcode versions and there is no documentation about joints. I tried to add them via the available API but regardless of how I combine pins, joints and various component, my entities will not get restricted or stay fixated like they are when they are in a child/parent relationship. I am using RealityKit and RealityView in mixed mode. I also searched the whole internet for related information without finding anything. Any insights or pointers appreciated!

Hello, I have an iOS app that is using SwiftUI but the gesture code is written using UIGestureRecognizer. When I run this app on visionOS using the "Designed for iPad" destination and try to use any of my gestures I see this warning in the console: Trying to convert coordinates between views that are in different UIWindows, which isn't supported. Use convertPoint:fromCoordinateSpace: instead. But I don't see any visible problems with the gestures. I see this warning printed out after the gesture takes place but before any of our gesture methods get kicked off. So now I am wondering if this is something we need to deal with or some internal work that needs to happen in UIKit. Does anyone have any thoughts on this?

If I attach my swiftui view via an ViewAttachmentEntity it will show the view but any ornaments defined are not showing up at all. When I use Xcode preview on the swiftui view the ornaments show up correctly. I am using visionOS beta 3 and the problem easy to reproduce. Are ornaments on views supported if the view is displayed via an ViewAttachmentEntity?

What’s the difference between an action and an animation eg.: FromToByAnimation vs FromToByAction. The documentation on them is pretty similar and I'm not understanding the differences exactly... : S FromToByAnimation → https://developer.apple.com/documentation/realitykit/fromtobyanimation?changes=__2_2 FromToByAction → https://developer.apple.com/documentation/realitykit/fromtobyaction?changes=__2_2 As developer, when should we reach out to use an animation vs action ? 🤔

Hi, I have a Spatial Video that I am trying to load in a visionOS app with PreviewApplication API let url = URL(string: "https://mauiman.azureedge.net/videos/SpatialJourney/watermelon_cat.MOV") let item = PreviewItem(url: url!) _ = PreviewApplication.open(items: [item]) When I run the application, I am getting the following error.

I am using Model3D to display an RCP scene/model in my UI. How can I get to the entities so I can set material properties to adjust the appearance? I looked at interfaces for Model3D and ResolvedModel3D and could not find a way to get access to the RCP scene or RealityKit entity.

I have looked here: Reality View Documentation Found this thread: RealityView Update Closure Thread I am not able to find documentation on how the update closure works. I am loading attachments using reality view's attachment feature (really helpful). I want to remove them programmatically from another file. I found that @State variables can be used. But I am not able to modify them from out side of the ImmersiveView swift file. The second problem I faced was even if I update them inside the file. My debugging statements don't execute. So exactly when does update function run. I know it get's executed at the start (twice for some reason). It also get's executed when I add a window using: openWindow?(id: "ButtonView") I need to use the update closure because I am also not able to get the reference to RealityViewAttachment outside the RealityView struct. My Code(only shown the code necessary. there is other code): @State private var pleaseRefresh = "" @StateObject var model = HandTrackingViewModel() var body: some View { RealityView { content, attachments in if let immersiveContentEntity = try? await Entity(named: "Immersive", in: realityKitContentBundle) { content.add(immersiveContentEntity) } content.add(model.setupContentEntity()) content.add(entityDummy) print("View Loaded") } update: { content, attachments in print("Update Closure Executed") if (model.editWindowAdded) { print("WINDOW ADDED") let theattachment = attachments.entity(for: "sample")! entityDummy.addChild(theattachment) // more code here } } attachments: { Attachment(id: "sample") { Button(action: { model.canEditPos = true model.canRotate = false pleaseRefresh = "changed" }) { HStack { Image(systemName: "pencil.and.outline") .resizable() .scaledToFit() .frame(width: 32, height: 32) Text("Edit Placement") .font(.caption) } .padding(4) } .frame(width: 160, height: 60) } } How can the update method (or the code inside it) run when I want it to? I am new to swift. I apologize if my question seems naive.

Just like this pic shows, how to add secondary panel out side of the main panel by using SwiftUI?

Is it possible to access the main camera feed in full frame using the Enterprise API? Image tracking in Vision OS only updates once per second, so I am considering using the Enterprise API to access the camera feed and implement it using our custom learning model. Please provide a response.

On TikTok on Vision Pro, the home page has different minimum and maximum window heights and widths compared to the search page. Now I am able to set minimum window size for different tab views but maximum size doesn't seem to work Code: // WindowSizeModel.swift import Foundation import SwiftUI enum TabType { case home case search case profile } @Observable class WindowSizeModel { var minWidth: CGFloat = 400 var maxWidth: CGFloat = 500 var minHeight: CGFloat = 400 var maxHeight: CGFloat = 500 func setWindowSize(for tab: TabType) { switch tab { case .home: configureWindowSize(minWidth: 400, maxWidth: 500, minHeight: 400, maxHeight: 500) case .search: configureWindowSize(minWidth: 300, maxWidth: 800, minHeight: 300, maxHeight: 800) case .profile: configureWindowSize(minWidth: 800, maxWidth: 1000, minHeight: 800, maxHeight: 1000) } } private func configureWindowSize(minWidth: CGFloat, maxWidth: CGFloat, minHeight: CGFloat, maxHeight: CGFloat) { self.minWidth = minWidth self.maxWidth = maxWidth self.minHeight = minHeight self.maxHeight = maxHeight } } // tiktokForSpacialModelingApp.swift import SwiftUI @main struct tiktokForSpacialModelingApp: App { @State private var windowSizeModel: WindowSizeModel = WindowSizeModel() var body: some Scene { WindowGroup { MainView() .frame( minWidth: windowSizeModel.minWidth, maxWidth: windowSizeModel.maxWidth, minHeight: windowSizeModel.minHeight, maxHeight: windowSizeModel.maxHeight) .environment(windowSizeModel) } .windowResizability(.contentSize) } } // MainView.swift import SwiftUI import RealityKit struct MainView: View { @State private var selectedTab: TabType = TabType.home @Environment(WindowSizeModel.self) var windowSizeModel; var body: some View { @Bindable var windowSizeModel = windowSizeModel TabView(selection: $selectedTab) { Tab("Home", systemImage: "play.house", value: TabType.home) { HomeView() } Tab("Search", systemImage: "magnifyingglass", value: TabType.search) { SearchView() } Tab("Profile", systemImage: "person.crop.circle", value: TabType.profile) { ProfileView() } } .onAppear { windowSizeModel.setWindowSize(for: TabType.home) } .onChange(of: selectedTab) { oldTab, newTab in if oldTab == newTab { return } else if newTab == TabType.home { windowSizeModel.setWindowSize(for: TabType.home) } else if newTab == TabType.search { windowSizeModel.setWindowSize(for: TabType.search) } else if newTab == TabType.profile { windowSizeModel.setWindowSize(for: TabType.profile) } } } }

Hello! I have an iOS app where I am looking into support for visionOS. I have a whole bunch of gestures set up using UIGestureRecognizer and so far most of them work great in visionOS! But I do see something odd that I am not sure can be fixed on my end. I have a UITapGestureRecognizer which is set up with numberOfTouchesRequired = 2 which I am assuming translates in visionOS to when you tap your thumb and index finger on both hands. When I tap with both hands sometimes this tap gesture gets kicked off and other times it doesn't and it says it only received one touch when it should be two. Interestingly, I see this behavior in Apple Maps where tapping once with both hands should zoom out the map, which only works sometimes. Can anyone explain this or am I missing something?

I have an application that is meant to be a "watch together" GroupActivity using SharePlay that coordinates video playback using AVPlayerPlaybackCoordinator. In the current implementation, the activity begins before opening the AVPlayer, however when clicking the back button within the AVPlayer view, the user is prompted to "End Activity for Everyone" or "End Activity for just me". There is not an option to continue the group activity. My goal is to retain the same GroupSession, even if a user exits the AVPlayer view. Is there a way to avoid ending the session when coordinating playback using the AVPlayerPlaybackCoordinator? private func startObservingSessions() async { sessionInfo = .init() // Await new sessions to watch video together. for await session in MyActivity.sessions() { // Clean up the old session, if it exists. cleanUpSession(groupSession) #if os(visionOS) // Retrieve the new session's system coordinator object to update its configuration. guard let systemCoordinator = await session.systemCoordinator else { continue } // Create a new configuration that enables all participants to share the same immersive space. var configuration = SystemCoordinator.Configuration() // Sets up spatial persona configuration configuration.spatialTemplatePreference = .sideBySide configuration.supportsGroupImmersiveSpace = true // Update the coordinator's configuration. systemCoordinator.configuration = configuration #endif // Set the app's active group session before joining. groupSession = session // Store session for use in sending messages sessionInfo?.session = session let stateListener = Task { await self.handleStateChanges(groupSession: session) } subscriptions.insert(.init { stateListener.cancel() }) // Observe when the local user or a remote participant changes the activity on the GroupSession let activityListener = Task { await self.handleActivityChanges(groupSession: session) } subscriptions.insert(.init { activityListener.cancel() }) // Join the session to participate in playback coordination. session.join() } } /// An implementation of `AVPlayerPlaybackCoordinatorDelegate` that determines how /// the playback coordinator identifies local and remote media. private class CoordinatorDelegate: NSObject, AVPlayerPlaybackCoordinatorDelegate { var video: Video? // Adopting this delegate method is required when playing local media, // or any time you need a custom strategy for identifying media. Without // implementing this method, coordinated playback won't function correctly. func playbackCoordinator(_ coordinator: AVPlayerPlaybackCoordinator, identifierFor playerItem: AVPlayerItem) -> String { // Return the video id as the player item identifier. "\(video?.id ?? -1)" } } /// /// Initializes the playback coordinator for synchronizing video playback func initPlaybackCoordinator(playbackCoordinator: AVPlayerPlaybackCoordinator) async { self.playbackCoordinator = playbackCoordinator if let coordinator = self.playbackCoordinator { coordinator.delegate = coordinatorDelegate } if let activeSession = groupSession { // Set the group session on the AVPlayer instances's playback coordinator // so it can synchronize playback with other devices. playbackCoordinator.coordinateWithSession(activeSession) } } /// A coordinator that acts as the player view controller's delegate object. final class PlayerViewControllerDelegate: NSObject, AVPlayerViewControllerDelegate { let player: PlayerModel init(player: PlayerModel) { self.player = player } #if os(visionOS) // The app adopts this method to reset the state of the player model when a user // taps the back button in the visionOS player UI. func playerViewController(_ playerViewController: AVPlayerViewController, willEndFullScreenPresentationWithAnimationCoordinator coordinator: UIViewControllerTransitionCoordinator) { Task { @MainActor in // Calling reset dismisses the full-window player. player.reset() } } #endif }
