If I long press on an element, the sidebar disappears and then a Done appears on the screen, but nothing else changes, so what are the Environments in Vision Pro's Simulator?

I want to open the control center in Vision Pro’s Xcode simulator. Can I open it? If I can, please tell me how to do it. Thank you.

Spatial photo in RealityView has a default corner radius. I made a parallel effect with spatial photos in ScrollView(like Spatial Gallery), but the corner radius disappeared on left and right spatial photos. I've tried .clipShape and .mask modifiers, but they did't work. How to clip or mask spatial photo with corner radius effect?

I want an AR character to be able to look at a position while still playing the characters animation. So far, I managed to manually adjust a single bone rotation using skeletalComponent.poses.default = Transform( scale: baseTransform.scale, rotation: lookAtRotation, translation: baseTransform.translation ) which I run at every rendering update, while a full body animation is running. But of course, hardcoding single joints to point into a direction (in my case the head) does not look as nice, as if I were to run some inverse cinematic that includes, hips + neck + head joints. I found some good IKRig code in Composing interactive 3D content with RealityKit and Reality Composer Pro. But when I try to adjust rigs while animations are playing, the animations are usually winning over the IKRig changes to the mesh.

We can add ornaments to popovers shown by PresentationComponent, but I’m not sure if we should. While working on the editor for entities in a Volume-based app, I had the idea to add ornaments to the presented views. The entire app exists inside a volume. A user can tap a item to present a popoverUI to edit it. This is displayed using the new PresentationComponent in visionOS 26. Ornaments have a new attachment anchor option this year: .parent(). .ornament(attachmentAnchor: .parent(.top), ornament: {...}) This works well in the Simulator. We can add ornaments around this popover view just like we would with a window. Unfortunately, when I run this on device I get a different experience. Any part of the ornament that overlaps with the popover content isn’t rendered correctly. Sometimes it entirely disappears, other times it becomes partially transparent. We could use content alignment to try to make sure the ornament doesn’t overlap the popover content. .ornament(attachmentAnchor: .parent(.top), contentAlignment: .bottom, ornament: {...}) This works sometimes–but not all the time. It’s not clear if this is a bug or not, because I’m not sure if we are even supposed to be able to use ornaments in this way. Here is my hierarchy: An app opens as a Volume Volume presenting a RealityView, with its own ornament using .scene() anchor Multiple Entities with Presentation Component show an edit view The view uses .parent() anchor to add ornaments. What makes me unsure is that other methods for drawing UI in RealityView don’t seem to work with ornaments. For example, if I add an attachment to show a view with the ornament–even when I use the .parent() anchor–the ornament is anchor to the volume, not the attachment view. So what do we think? Is this a rendering bug? Are ornaments intended to work with attachments and presentations?

So, I was trying to animate a single bone using FromToByAnimation, but when I start the animation, the model instead does the full body animation stored in the availableAnimations. If I don't run testAnimation nothing happens. If I run testAnimation I see the same animation as If I had called entity.playAnimation(entity.availableAnimations[0],..) here's the full code I use to animate a single bone: func testAnimation() { guard let jawAnim = jawAnimation(mouthOpen: 0.4) else { print("Failed to create jawAnim") return } guard let creature, let animResource = try? AnimationResource.generate(with: jawAnim) else { return } let controller = creature.playAnimation(animResource, transitionDuration: 0.02, startsPaused: false) print("controller: \(controller)") } func jawAnimation(mouthOpen: Float) -> FromToByAnimation<JointTransforms>? { guard let basePose else { return nil } guard let index = basePose.jointNames.firstIndex(of: jawBoneName) else { print("Target joint \(self.jawBoneName) not found in default pose joint names") return nil } let fromTransforms = basePose.jointTransforms let baseJawTransform = fromTransforms[index] let maxAngle: Float = 40 let angle: Float = maxAngle * mouthOpen * (.pi / 180) let extraRot = simd_quatf(angle: angle, axis: simd_float3(x: 0, y: 0, z: 1)) var toTransforms = basePose.jointTransforms toTransforms[index] = Transform( scale: baseJawTransform.scale * 2, rotation: baseJawTransform.rotation * extraRot, translation: baseJawTransform.translation ) let fromToBy = FromToByAnimation<JointTransforms>( jointNames: basePose.jointNames, name: "jaw-anim", from: fromTransforms, to: toTransforms, duration: 0.1, bindTarget: .jointTransforms, repeatMode: .none, ) return fromToBy } PS: I can confirm that I can set this bone to a specific position if I use guard let index = newPose.jointNames.firstIndex(of: boneName) ... let baseTransform = basePose.jointTransforms[index] newPose.jointTransforms[index] = Transform( scale: baseTransform.scale, rotation: baseTransform.rotation * extraRot, translation: baseTransform.translation ) skeletalComponent.poses.default = newPose creatureMeshEntity.components.set(skeletalComponent) This works for manually setting the bone position, so the jawBoneName and the joint-transformation can't be that wrong.

This post documents an issue I reported in feedback FB19610114 and see if anyone knows of a workaround. Here is a copy of the feedback. Short version Manipulation (SwiftUI OR RealityKit) fails to translate entities after changing rooms. By changing rooms, I mean a human wearing an Apple Vision Pro leaving one room and entering another room. Once this issue occurs, it impacts all apps that use these features. A device restart is the only solution I have to fix it. Feedback FB19610114 This is an odd one. I'm using the new Manipulation Component in visionOS 26. Most of the time this works well. Sometime it stops working and when it does the only way to get it working again is to reboot the headset. When this happens, I can continue to rotate and scale items, but translation no longer works. It is as if the item is stuck to a fixed point in the parent scene (window, volume, etc). When this bug occurs, it affects every app across the entire operating system that is using manipulation, including the RealityKit component AND the SwiftUI version. This is not limited to one app and is not limited to apps that I am working on. Once this error occurs, it affects literally any application across the operating system that is using this API, including apps from Apple. I won't speculate on the cause of this, but I do know of one way where I can always get it to happen. Here is how to reproduce it: Make an Xcode project with a single entity that uses the Manipulation Component. There is no need to customize the configuration of this component. The default implementation will work. Build and run this app on device. You can keep running from device or quit and launch the app like normal on device. Open the app and manipulate the entity - it should work as expected. Physically walk into another room. It is vital that you leave the current room that you are in and enter a different room entirely. Use the digital crown to recenter your view and bring your window or volume to you. Test the manipulation on the entity again - it should still be working as expected at this point. Physically, move yourself and your headset into the original room where you started. Use the digital crown to recenter your view and bring your window or volume to you. Test the manipulation on the entity again - you should now see the issue. When I follow the steps above, then 100% of the time manipulation translation stops working at this point. It will impact any application using this API. The only way to fix it is to restart my headset. A few points to keep in mind It does not matter if an app is actively being run from Xcode. When this occurs, it impacts every single app, not just one. When this occurs, rotation and scaling continue to work, but the entity/view cannot be translated. This impacts BOTH the SwiftUI version and the RealityKit version. When this occurs, the only way to "fix" it is to reboot the device.

On Xcode 26 and visionOS 26, apple provides observable property for Entity, so we can easily interact with Entity between RealityScene and SwiftUI, but there is a issue: It's fine to observe Entity's position and scale properties in Slider, but can't observe orientation properties in Slider.

I have a visionOS 2 project created on Xcode 16, when I updated to Xcode 26 beta5, I can't build it any more, every time it stuck in process like the picture shows below: Already tried many methods to fix this issue, such as clear build folders, but don't work.

I’m working with RealityView in visionOS and noticed that the content closure seems to run twice, causing content.add to be called twice automatically. This results in duplicate entities being added to the scene unless I manually check for duplicates. How can I fix that? Thanks.

In WWDC25 session What’s new for the spatial web, the presenter showed creating an immersive environment for a web page by adding to the page's HEAD section <link rel="spatial-backdrop" href="office.usdz" environmentmap="lighting.hdr"> My first attempt failed, and I am trying to track down why. Before I search all the potential failure paths, I wanted to ask the community, Is this feature available in the latest visionOS 26 beta? I haven't seen anyone talk about their use of the feature yet.

I've been struggling with this for far too long so I've decided to finally come here and see if anyone can point me to the documentation that I'm missing. I'm sure it's something so simple but I just can't figure it out. I can SharePlay our test app with my brother (device to device) but when I open a volumetric window, it says "not shared" under it. I assume this will likely fix the video sharing problem we have as well. Everything else works so smooth but SharePlay has just been such a struggle for me. It's the last piece to the puzzle before we can put it on the App Store.

Hey all, I'm working on a visionOS app that captures live frames from the left and right cameras of Apple Vision Pro using cameraFrame.sample(for: .left/.right). Apple provides documentation on encoding side-by-side frames into MV-HEVC spatial video using CMTaggedBuffer: Converting Side-by-Side 3D Video to MV-HEVC My question: Is there any way to render tagged frames (e.g. CMTaggedBuffer with .stereoView(.leftEye/.rightEye)) live, directly to a surface in RealityKit or Metal, without saving them to a file? I’d like to create a true stereoscopic (spatial) live video preview, not just render two images side-by-side. Any advice or insights would be greatly appreciated!

Hi , I'm struggling with visionOS window management and need help with closing child windows programmatically. App Structure My app has a Main-Sub window hierarchy: AWindow (Home/Main) BWindow (Main feature window) CWindow (Tool window - child of BWindow) Navigation flow: AWindow → BWindow (switch, 1 window on screen) BWindow → CWindow (opens child, 2 windows on screen) I want BWindow and CWindow to be separate movable windows (not sheet/popover) so users can position them independently in space. The Problem CWindow doesn't close when BWindow closes by tapping the X button below the app (next to the window bar) User clicks X on BWindow → BWindow closes but CWindow remains CWindow becomes orphaned on screen Can close CWindow programmatically when switching BWindow back to AWindow App launch issue After closing both windows, CWindow is remembered as last window Reopening app shows only CWindow instead of BWindow User gets stuck in CWindow with no way back to BWindow I've Tried Environment dismissWindow in cleanup but its not working. // In BWindow.swift .onDisappear { if windowManager.isWindowOpen("cWindow") { dismissWindow(id: "cWindow") } } My App Structure Code Now // in MyNameApp.swift @main struct MyNameApp: App { var body: some Scene { WindowGroup(id: "aWindow") { AWindow() } WindowGroup(id: "bWindow") { BWindow() } WindowGroup(id: "cWindow") { CWindow() } } } // WindowStateManager.swift class WindowStateManager: ObservableObject { static let shared = WindowStateManager() @Published private var openWindows: Set<String> = [] @Published private var windowDependencies: [String: String] = [:] private init() {} func markWindowAsOpen(_ id: String) { markWindowAsOpen(id, parent: nil) } func markWindowAsClosed(_ id: String) { openWindows.remove(id) windowDependencies[id] = nil } func isWindowOpen(_ id: String) -> Bool { let isOpen = openWindows.contains(id) return isOpen } func markWindowAsOpen(_ id: String, parent: String? = nil) { openWindows.insert(id) if let parentId = parent { windowDependencies[id] = parentId } } func getParentWindow(of childId: String) -> String? { let parent = windowDependencies[childId] return parent } func getChildWindows(of parentId: String) -> [String] { let children = windowDependencies.compactMap { key, value in value == parentId ? key : nil } return children } func setNextWindowParent(_ parentId: String) { UserDefaults.standard.set(parentId, forKey: "nextWindowParent") } func getAndClearNextWindowParent() -> String? { let parent = UserDefaults.standard.string(forKey: "nextWindowParent") UserDefaults.standard.removeObject(forKey: "nextWindowParent") return parent } func forceCloseChildWindows(of parentId: String) { let children = getChildWindows(of: parentId) for child in children { markWindowAsClosed(child) NotificationCenter.default.post( name: Notification.Name("ForceCloseWindow"), object: nil, userInfo: ["windowId": child] ) forceCloseChildWindows(of: child) } } func hasMainWindowOpen() -> Bool { let mainWindows = ["main", "bWindow"] return mainWindows.contains { isWindowOpen($0) } } func cleanupOrphanWindows() { for (child, parent) in windowDependencies { if isWindowOpen(child) && !isWindowOpen(parent) { NotificationCenter.default.post( name: Notification.Name("ForceCloseWindow"), object: nil, userInfo: ["windowId": child] ) markWindowAsClosed(child) } } } } // BWindow.swift struct BWindow: View { @Environment(\.dismissWindow) private var dismissWindow @ObservedObject private var windowManager = WindowStateManager.shared var body: some View { VStack { Button("Open C Window") { windowManager.setNextWindowParent("bWindow") openWindow(id: "cWindow") } } .onAppear { windowManager.markWindowAsOpen("bWindow") } .onDisappear { windowManager.markWindowAsClosed("bWindow") windowManager.forceCloseChildWindows(of: "bWindow") } .onChange(of: scenePhase) { oldValue, newValue in if newValue == .background || newValue == .inactive { windowManager.forceCloseChildWindows(of: "bWindow") } } } } // CWindow.swift import SwiftUI struct cWindow: View { @ObservedObject private var windowManager = WindowStateManager.shared @State private var shouldClose = false var body: some View { // Content } .onDisappear { windowManager.markWindowAsClosed("cWindow") NotificationCenter.default.removeObserver( self, name: Notification.Name("ForceCloseWindow"), object: nil ) } .onChange(of: scenePhase) { oldValue, newValue in if newValue == .background { } } .onAppear { let parent = windowManager.getAndClearNextWindowParent() windowManager.markWindowAsOpen("cWindow", parent: parent) NotificationCenter.default.addObserver( forName: Notification.Name("ForceCloseWindow"), object: nil, queue: .main) { notification in if let windowId = notification.userInfo?["windowId"] as?

Questions Why doesn't dismissWindow(id:) work in cleanup scenarios? Is there a proper way to create a window relationships like parent-child relationships in visionOS? How can I ensure main windows open on app launch instead of tool windows? What's the recommended pattern for dependent windows in visionOS? Environment: Xcode 16.2, visionOS 2.0, SwiftUI

Hi! I'm currently trying to render another XR scene in front of a RealityKit one. Actually, I'm anchoring a plane to the head with a shader to display for left/right eye side-by-side images. By default, the camera has a near plane so I can directly draw at z=0. Is there a way to change the camera near plane? Or maybe there is a better solution to overlay image/texture for left/right eyes? Ideally, I would layer some kind of CompositorLayer on RealityKit, but that's sadly not possible from what I know. Thanks in advance and have a good day!

I am working on an app that will allow a user to load and share their model files (usdz, usda, usdc). I'm looking at security options to prevent bad actors. Are there security or validation methods built into ARKit/RealityKit/CloudKit when loading models or saving them on the cloud? I want to ensure no one can inject any sort of exploit through these file types.

I've tried following apple's documentation to apply a video material on a Model Entity, but I have encountered a compile error while attempting to specify the Spatial Audio type. It is a 360 video on a Sphere which plays just fine, but the audio is too quiet compared to the volume I get when I preview the video on Xcode. So I tried tried to configure audio playback mode on the material but it gives me a compile error: "audioInputMode' is unavailable in visionOS audioInputMode' has been explicitly marked unavailable here RealityFoundation.VideoPlaybackController.audioInputMode)" https://developer.apple.com/documentation/realitykit/videomaterial/ Code: let player = AVPlayer(url: url) // Instantiate and configure the video material. let material = VideoMaterial(avPlayer: player) // Configure audio playback mode. material.controller.audioInputMode = .spatial // this line won’t compile. VisionOS 2.4, Xcode 16.4, also tried Xcode 26 beta 2. The videos are HEVC MPEG-4 codecs. Is there any other way to do this, or is there a workaround available? Thank you.

The issue reproducible with empty project. When you run it and tap "Open immersive space" it takes a couple of minutes to respond. The issue only reproducible on real device with debugger attached.

After updating to the latest visionOS beta, visionOS 26 Beta 4 (23M5300g) the ‘Presenting images in RealityKit’ sample from the following link no longer builds due to an error. https://developer.apple.com/documentation/RealityKit/presenting-images-in-realitykit Expected / Previous: Application builds and runs on device, working as described in the documentation. Reality: Application builds, but does not run on device due to an error (shown in screenshot) “Thread 1: EXC_BAD_ACCESS (code=1, address=0xb)”. The application still runs on the simulator, but not on device. When launching the app from Xcode, it builds and installs correctly but hangs due to the respective error. When loading the app from the Home Screen, the app does not load, and immediately returns to the Home Screen. This Xcode project previously ran with no changes to code - the only change was updating the visionOS system software to the latest version. visionOS 26 Beta 4 (23M5300g) Is anyone else experiencing this issue?

prefetching logic for UICollectionView on VisionOS does not work. I have set up a Standalone test repo to demonstrate this issue. This repo is basically a visionOS version of Apple's guide project on implementation of prefetching logic. in repo you will see a simple ViewController that has UICollectionView, wrapped inside UIViewControllerRepresentable. on scroll, it should print 🕊️ prefetch start on console to demonstrate func collectionView(_ collectionView: UICollectionView, prefetchItemsAt indexPaths: [IndexPath]) is called. However it never happens on VisionOS devices. With the same code it behaves correctly on iOS devices
