How to Renew visionOS Enterprise API Entitlements?
How can I renew visionOS Enterprise API? I've spent so much time contacting Apple Developer Support. They said they don't know the renewal process either and are "checking with the internal operations team" - but it's been 2 months with no updates. The official documentation (https://developer.apple.com/documentation/visionOS/building-spatial-experiences-for-business-apps-with-enterprise-apis#Request-the-entitlements) says: "The license file comes with an expiration date, so you need to renew it before then to ensure your entitlements continue to function." But it doesn't explain HOW to renew. When I asked Apple Support about this, they told me: "After Apple approves your app for one or more entitlements, you receive a license file, along with additional instructions." But I never received any instructions when I was first approved, and I still don't know how to renew. There's also no direct way to contact the Enterprise API team. Now my visionOS Enterprise API license has been expired for 2 months. I submitted a renewal request, but I still haven't heard anything back. Is it normal to take more than 2 months for approval? Any advice or shared experiences would be really helpful. Thanks!

Displaying spatial photos and videos on web pages in Safari
The purpose is to create a simple web-based gallery of spatial photos and videos using static html files. I have successfully displayed spatial photos using the img tag and IMG.heic files. I can tap and hold the image to bring up the contextual menu and from there select View Spatial Photo. Is there any way to add a control to the image, like a link or overlay on the image itself, that a user can simply tap to show the image in 3D? And how to host a video file on a web page without going through a CDN/streaming service? Sample html would be much appreciated.

Displaying multiple immersive movies in spheres in an immersive environment
In visionOS, I'm trying to create an immersive environment which would feature several spheres in which immersive movies are visible. I'm starting from a sample code which creates a sphere, sets an immersive movie as its material, and opens it as an immersive environment. This works fine. But if I create a sphere in an open immersive environment using Reality Composer Pro and sets its material to an immersive movie, I can see the movie on the sphere while I move outside of it but if I try to get inside the sphere, it disappears. What would be the right way of doing this ?

Using AVAsynchronousKeyValueLoading.load() on an AVAssetTrack gives an error
I'm seeing this error while attempting to compile my VisionOS app under Xcode 26. My existing code looks like: let (naturalSize, formatDescriptions, mediaCharacteristics) = try? await videoTrack.load(.naturalSize, .formatDescriptions, .mediaCharacteristics) This is now giving a compiler error: Type of expression is ambiguous without a type annotation I don't see that anything that was changed or deprecated in the latest version. Also loading the properties individually seems to work fine i.e.: let naturalSize = try? await videoTrack.load(.naturalSize) let formatDescriptions = try? await videoTrack.load(.formatDescriptions) let mediaCharacteristics = try? await videoTrack.load(.mediaCharacteristics)

Setting immerstionStyle while in immersive space breaks all entities.
I have my immersive space set up like: ImmersiveSpace(id: "Theater") { ImmersiveTeleopView() .environment(appModel) .onAppear() { appModel.immersiveSpaceState = .open } .onDisappear { appModel.immersiveSpaceState = .closed } } .immersionStyle(selection: .constant(appModel.immersionStyle.style), in: .mixed, .full) Which allows me to set the immersive style while in the space (from a Picker on a SwiftUI window). The scene responds correctly but a lot of the functionality of my immersive space is gone after the change in style; in that I am no longer able to enable/disable entities (which I also have a toggles for in the SwiftUI window). I have to exit and reenter the immersive space to regain the ability to change the enabled state of my entities. My appModel.immersionStyle is inspired by the Compositor-Services demo (although I am using a RealityView) listed in https://developer.apple.com/documentation/CompositorServices/interacting-with-virtual-content-blended-with-passthrough and looks like this: public enum IStyle: String, CaseIterable, Identifiable { case mixedStyle, fullStyle public var id: Self { self } var style: ImmersionStyle { switch self { case .mixedStyle: return .mixed case .fullStyle: return .full } } } /// Maintains app-wide state @MainActor @Observable class AppModel { // Immersion Style public var immersionStyle: IStyle = .mixedStyle

Implementing Foveated Streaming with Apple Vision Pro
Hello, Want to understand what's the current state for developing for Apple Vision Pro? I want to stream a video from a remote server in realtime. It is a video stream and can't download it. I want to stream a low quality stream and high res stream. The server will only send the "box" where user is looking at. Are there any API to track where the user is looking at in the experience? Thanks,

AVPlayer stutters when using AVPlayerItemVideoOutput
We’re trying to build a custom player for Unity. For this, we’re using AVPlayer with AVPlayerItemVideoOutput to get textures. However, we noticed that playback is not smooth and the stream often freezes. For testing, we used this 8K video: https://deovr.com/nwfnq1 The video was played using the following code: @objc public func playVideo(urlString: String) { guard let url = URL(string: urlString) else { return } let pItem = AVPlayerItem(url: url) playerItem = pItem pItem.preferredForwardBufferDuration = 10.0 let pixelBufferAttributes: [String: Any] = [ kCVPixelBufferPixelFormatTypeKey as String: kCVPixelFormatType_420YpCbCr8BiPlanarVideoRange, kCVPixelBufferMetalCompatibilityKey as String: true, ] let output = AVPlayerItemVideoOutput( pixelBufferAttributes: pixelBufferAttributes ) pItem.add(output) playerItemObserver = pItem.observe(\.status) { [weak self] pItem, _ in guard pItem.status == .readyToPlay else { return } self?.playerItemObserver = nil self?.player.play() } player = AVPlayer(playerItem: pItem) player.currentItem?.preferredPeakBitRate = 35_000_000 } When AVPlayerItemVideoOutput is attached, the video stutters and the log looks like this: 🟢 Playback likely to keep up 🟡 Buffer ahead: 4.08s | buffer: 4.08s 🟡 Buffer ahead: 4.08s | buffer: 4.08s 🟡 Buffer ahead: -0.07s | buffer: 0.00s 🟡 Buffer ahead: 2.94s | buffer: 3.49s 🟡 Buffer ahead: 2.50s | buffer: 4.06s 🟡 Buffer ahead: 1.74s | buffer: 4.30s 🟡 Buffer ahead: 0.74s | buffer: 4.30s 🟠 Playback may stall 🛑 Buffer empty 🟡 Buffer ahead: 0.09s | buffer: 4.30s 🟠 Playback may stall 🟠 Playback may stall 🛑 Buffer empty 🟠 Playback may stall 🟣 Buffer full 🟡 Buffer ahead: 1.41s | buffer: 1.43s 🟡 Buffer ahead: 1.41s | buffer: 1.43s 🟡 Buffer ahead: 1.07s | buffer: 1.43s 🟣 Buffer full 🟡 Buffer ahead: 0.47s | buffer: 1.65s 🟠 Playback may stall 🛑 Buffer empty 🟡 Buffer ahead: 0.10s | buffer: 1.65s 🟠 Playback may stall 🟡 Buffer ahead: 1.99s | buffer: 2.03s 🟡 Buffer ahead: 1.99s | buffer: 2.03s 🟣 Buffer full 🟣 Buffer full 🟡 Buffer ahead: 1.41s | buffer: 2.00s 🟡 Buffer ahead: 0.68s | buffer: 2.27s 🟡 Buffer ahead: 0.09s | buffer: 2.27s 🟠 Playback may stall 🛑 Buffer empty 🟠 Playback may stall When we remove AVPlayerItemVideoOutput from the player, the video plays smoothly, and the output looks like this: 🟢 Playback likely to keep up 🟡 Buffer ahead: 1.94s | buffer: 1.94s 🟡 Buffer ahead: 1.94s | buffer: 1.94s 🟡 Buffer ahead: 1.22s | buffer: 2.22s 🟡 Buffer ahead: 1.05s | buffer: 3.05s 🟡 Buffer ahead: 1.12s | buffer: 4.12s 🟡 Buffer ahead: 1.18s | buffer: 5.18s 🟡 Buffer ahead: 0.72s | buffer: 5.72s 🟡 Buffer ahead: 1.27s | buffer: 7.28s 🟡 Buffer ahead: 2.09s | buffer: 3.03s 🟡 Buffer ahead: 4.16s | buffer: 6.10s 🟡 Buffer ahead: 6.66s | buffer: 7.09s 🟡 Buffer ahead: 5.66s | buffer: 7.09s 🟡 Buffer ahead: 4.66s | buffer: 7.09s 🟡 Buffer ahead: 4.02s | buffer: 7.45s 🟡 Buffer ahead: 3.62s | buffer: 8.05s 🟡 Buffer ahead: 2.62s | buffer: 8.05s 🟡 Buffer ahead: 2.49s | buffer: 3.53s 🟡 Buffer ahead: 2.43s | buffer: 3.38s 🟡 Buffer ahead: 1.90s | buffer: 3.85s We’ve tried different attribute settings for AVPlayerItemVideoOutput. We also removed all logic related to reading frame data, but the choppy playback still remained. Can you advise whether this is a player issue or if we’re doing something wrong?

Building a Full Space app that enables sharing a visionOS experience with nearby users.
Hello, I am currently considering developing a Full Space app that enables a shared visionOS experience with nearby users. Intended Features A Mixed Full Space app in which dozens of 3D models are placed in the space. These 3D models may play embedded animations when tapped, be programmatically moved or rotated, or be controlled via Reality Composer Pro timelines. The app also includes audio, spatial audio, videos with audio, and videos without audio, which are rendered as VideoTextures on planes and played back in the space. Some media elements play automatically, while others are triggered by user interaction. However, it is unclear whether AVPlaybackCoordinator supports shared playback across multiple types of media, such as: audio only spatial audio video without audio video with audio I am also unsure whether there are alternative or recommended approaches for synchronizing playback in this scenario. Questions Is it technically possible to implement the experience described above using visionOS? Are there any important implementation considerations or limitations that should be taken into account? For example, when two participants experience the app simultaneously, how is the content positioned for each participant? Is the spatial placement of content shared across participants, or is it positioned relative to each participant’s viewpoint? For nearby participants, is it necessary to register a spatial Persona? My understanding is that spatial Personas are not visible for nearby users during the experience; is this correct? When experiencing SharePlay with nearby users, is it possible to share the experience without registering the other participant’s contact information? I have watched the following session, but I was unable to fully understand the feasibility of the above use case or the concrete implementation details: https://developer.apple.com/videos/play/wwdc2025/318/ Thank you.

I am developing a Immersive Video App for VisionOs but I got a issue regarding app and video player window
In Vision OS app, We have two types of windows: Main App Window – This is the default window that launches when the app starts. It displays the video listings and other primary content. Immersive Space Window – This opens only when a user starts streaming or playing a video. Issue: When entering the immersive space, the main app window remains visible in front of it unless manually closed. To avoid this, I currently close the main window when transitioning to immersive space and reopen it when exiting. However, this causes the app to restart instead of resuming from its previous state. Desired Behavior: I want the main app window to retain its state and seamlessly resume from where it was before entering immersive mode, rather than restarting. Attempts & Challenges: Tried managing opacity, visibility, and state preservation, but none worked as expected. Couldn’t find a way to push the main window to the background while bringing the immersive space to the foreground. Looking for a solution to keep the main window’s state intact while transitioning between immersive and normal modes.

onWorldRecenter memory leak and duplicate callbacks in ImmersiveSpace
Posting this here in case this information is helpful to other developers: As of visionOS 26.3 beta 1, onWorldRecenter has two significant issues: (FB21557639) Memory Leak: When onWorldRecenter is assigned to a RealityView within an ImmersiveSpace, it appears to retain a strong reference to the view's internal SwiftUI context. When the immersive space is dismissed, the view's @State objects will not be deallocated. Also, each time the immersive space view's body is executed, additional state storage will be allocated and leaked. Multiple Callbacks: When the user long-presses the Digital Crown, the onWorldRecenter closure will be called multiple times, once for each past view body execution, including those of immersive space views that have been previously dismissed. Although these issues seem to be most prevalent when onWorldRecenter is used with an ImmersiveSpace, they may also occur in the context of a WindowGroup under certain circumstances. It's possible to work around this problem by moving onWorldRecenter to an empty overlay view within the app's primary WindowGroup and forwarding the world recenter events to ImmersiveSpace views through a notification system, coupled with a debouncer as an extra precaution.

Please provide access to face tracking blendshapes on vision os
Apple, please provide access to face tracking blend shapes on vision os, just like you do on iOS. You have the best eye and face tracking implementation on the market, please let us use it. There is a sizable audience who will buy the headset just for it. I personally know multiple people who are not buying the headset simply because you locked those features out. No raw camera access is needed, just abstracted blendshapes values. You will make the headset so much more useful if you do this simple thing.

With manipulation component, once you let go, how to prevent the entity from disappearing while animating it back into the volume
So with the new ManipulationComponent, we can choose "stay" and then if you drag it out of your volume, once you let go it will instantly disappear. We can "animate" it back to inside the volume, eg.: content.subscribe(to: ManipulationEvents.WillRelease.self) { event in Entity.animate( .easeInOut(duration: 1), body: { event.entity.position = [0, 0.2, 0] }, completion: {} ) }, Howeve,r for the duration that it travels outside of the volume it's invisible the whole time. In this apple video, it seems to be visible when dragging and when letting go, but perhaps that's not a volume they're dragging it out of? https://youtu.be/VtenPKrvPOU?si=y1zoZOs2IMyDzOm6&t=1748 Does anyone know how to keep the entity visible even when after letting the entity go while you animate it back towards inside of your volume?

ImmersiveSpace orphaned when WindowGroup closes
Environment visionOS 26.1, Xcode 26.1.1 Problem When a WindowGroup opens an ImmersiveSpace and the user closes the window via X button, the async Task in .onDisappear gets cancelled before dismissImmersiveSpace() completes, leaving the ImmersiveSpace active with no way to exit. Steps WindowGroup opens ImmersiveSpace in .onAppear User clicks X to close window .onDisappear fires but async cleanup cancelled ImmersiveSpace remains active, user trapped Expected ImmersiveSpace dismissed when window closes Actual ImmersiveSpace remains active Code .onAppear { Task { await openImmersiveSpace(id: "VideoCallMainCamera") } } .onDisappear { Task { await dismissImmersiveSpace() // Gets cancelled } } What I've Tried Task in .onDisappear ❌ scenePhase monitoring ❌ High priority Task ❌ .restorationBehavior(.disabled) + .defaultLaunchBehavior(.suppressed) ✅ (prevents restoration but doesn't fix immediate cleanup) Question What's the recommended pattern for ensuring ImmersiveSpace cleanup when WindowGroup closes? Is there a way to block window closure until async cleanup completes, or should ImmersiveSpaces automatically dismiss with their parent window?

Share Extensions embedded in visionOS apps
I'm trying to add a feature to my app to allow a user to import items from other apps, like Safari, via the share sheet. I've done this many times on iOS/iPadOS easily with a Share Extension. From what I can tell, Xcode tells me share extensions are not available on visionOS - though my experience on device tells me differently (It seems Reminders, Notes & more implement them somehow.) I was finally able to get it working on device only...but I can now no longer test in the simulator, and have not found a way to distribute this app. When attempting to run on the simulator, I get this issue: Please try again later. Appex bundle at /Users/jason/Library/Developer/CoreSimulator/Devices/09A70160-4F4F-4F5E-B679-F6F7D876D7EF/data/Library/Caches/com.apple.mobile.installd.staging/temp.6OAEZp/extracted/LaunchBar.app/PlugIns/LaunchBarShareExtension.appex with id co.swiftfox.LaunchBar.ShareExtension specifies a value (com.apple.share-services) for the NSExtensionPointIdentifier key in the NSExtension dictionary in its Info.plist that does not correspond to a known extension point. When trying to archive an upload to test flight, I get this similar error: Invalid Info.plist value. The value for the key 'DTPlatformName' in bundle LaunchBar.app/PlugIns/LaunchBarShareExtension.appex is invalid. (ID: 207610c7-b7e1-48be-959b-22a43cd32d16) The app is for visionOS only - which I'm thinking might be the problem? The share extension is "Designed For iPhone" and requires me to include iPhone as a run destination. In the worst case I can build an iPhone UI for the app but I'd rather not, as it is very specific to visionOS. Has anyone successfully launched a share extension on a visionOS only app? I have an iPad app with a share extension that shows up fine on visionOS, but the issue seems to be specifically with visionOS only apps.

How to Renew visionOS Enterprise API Entitlements?
How can I renew visionOS Enterprise API? I've spent so much time contacting Apple Developer Support. They said they don't know the renewal process either and are "checking with the internal operations team" - but it's been 2 months with no updates. The official documentation (https://developer.apple.com/documentation/visionOS/building-spatial-experiences-for-business-apps-with-enterprise-apis#Request-the-entitlements) says: "The license file comes with an expiration date, so you need to renew it before then to ensure your entitlements continue to function." But it doesn't explain HOW to renew. When I asked Apple Support about this, they told me: "After Apple approves your app for one or more entitlements, you receive a license file, along with additional instructions." But I never received any instructions when I was first approved, and I still don't know how to renew. There's also no direct way to contact the Enterprise API team. Now my visionOS Enterprise API license has been expired for 2 months. I submitted a renewal request, but I still haven't heard anything back. Is it normal to take more than 2 months for approval? Any advice or shared experiences would be really helpful. Thanks!

I am developing a Immersive Video App for VisionOs but I got a issue regarding app and video player window
In Vision OS app, We have two types of windows: Main App Window – This is the default window that launches when the app starts. It displays the video listings and other primary content. Immersive Space Window – This opens only when a user starts streaming or playing a video. Issue: When entering the immersive space, the main app window remains visible in front of it unless manually closed. To avoid this, I currently close the main window when transitioning to immersive space and reopen it when exiting. However, this causes the app to restart instead of resuming from its previous state. Desired Behavior: I want the main app window to retain its state and seamlessly resume from where it was before entering immersive mode, rather than restarting. Attempts & Challenges: Tried managing opacity, visibility, and state preservation, but none worked as expected. Couldn’t find a way to push the main window to the background while bringing the immersive space to the foreground. Looking for a solution to keep the main window’s state intact while transitioning between immersive and normal modes.

There some limitations if I open a spatial photo with Quick Look when an immersive space is on?
When viewing an immersive space and I open a spatial photo in Quick Look, which hides the entire app interface to show the photo. Is there a memory limit? If the inmersive space is not active, the application keep the interface.

onWorldRecenter memory leak and duplicate callbacks in ImmersiveSpace
Posting this here in case this information is helpful to other developers: As of visionOS 26.3 beta 1, onWorldRecenter has two significant issues: (FB21557639) Memory Leak: When onWorldRecenter is assigned to a RealityView within an ImmersiveSpace, it appears to retain a strong reference to the view's internal SwiftUI context. When the immersive space is dismissed, the view's @State objects will not be deallocated. Also, each time the immersive space view's body is executed, additional state storage will be allocated and leaked. Multiple Callbacks: When the user long-presses the Digital Crown, the onWorldRecenter closure will be called multiple times, once for each past view body execution, including those of immersive space views that have been previously dismissed. Although these issues seem to be most prevalent when onWorldRecenter is used with an ImmersiveSpace, they may also occur in the context of a WindowGroup under certain circumstances. It's possible to work around this problem by moving onWorldRecenter to an empty overlay view within the app's primary WindowGroup and forwarding the world recenter events to ImmersiveSpace views through a notification system, coupled with a debouncer as an extra precaution.

Please provide access to face tracking blendshapes on vision os
Apple, please provide access to face tracking blend shapes on vision os, just like you do on iOS. You have the best eye and face tracking implementation on the market, please let us use it. There is a sizable audience who will buy the headset just for it. I personally know multiple people who are not buying the headset simply because you locked those features out. No raw camera access is needed, just abstracted blendshapes values. You will make the headset so much more useful if you do this simple thing.

With manipulation component, once you let go, how to prevent the entity from disappearing while animating it back into the volume
So with the new ManipulationComponent, we can choose "stay" and then if you drag it out of your volume, once you let go it will instantly disappear. We can "animate" it back to inside the volume, eg.: content.subscribe(to: ManipulationEvents.WillRelease.self) { event in Entity.animate( .easeInOut(duration: 1), body: { event.entity.position = [0, 0.2, 0] }, completion: {} ) }, Howeve,r for the duration that it travels outside of the volume it's invisible the whole time. In this apple video, it seems to be visible when dragging and when letting go, but perhaps that's not a volume they're dragging it out of? https://youtu.be/VtenPKrvPOU?si=y1zoZOs2IMyDzOm6&t=1748 Does anyone know how to keep the entity visible even when after letting the entity go while you animate it back towards inside of your volume?

ImmersiveSpace orphaned when WindowGroup closes
Environment visionOS 26.1, Xcode 26.1.1 Problem When a WindowGroup opens an ImmersiveSpace and the user closes the window via X button, the async Task in .onDisappear gets cancelled before dismissImmersiveSpace() completes, leaving the ImmersiveSpace active with no way to exit. Steps WindowGroup opens ImmersiveSpace in .onAppear User clicks X to close window .onDisappear fires but async cleanup cancelled ImmersiveSpace remains active, user trapped Expected ImmersiveSpace dismissed when window closes Actual ImmersiveSpace remains active Code .onAppear { Task { await openImmersiveSpace(id: "VideoCallMainCamera") } } .onDisappear { Task { await dismissImmersiveSpace() // Gets cancelled } } What I've Tried Task in .onDisappear ❌ scenePhase monitoring ❌ High priority Task ❌ .restorationBehavior(.disabled) + .defaultLaunchBehavior(.suppressed) ✅ (prevents restoration but doesn't fix immediate cleanup) Question What's the recommended pattern for ensuring ImmersiveSpace cleanup when WindowGroup closes? Is there a way to block window closure until async cleanup completes, or should ImmersiveSpaces automatically dismiss with their parent window?

Share Extensions embedded in visionOS apps
I'm trying to add a feature to my app to allow a user to import items from other apps, like Safari, via the share sheet. I've done this many times on iOS/iPadOS easily with a Share Extension. From what I can tell, Xcode tells me share extensions are not available on visionOS - though my experience on device tells me differently (It seems Reminders, Notes & more implement them somehow.) I was finally able to get it working on device only...but I can now no longer test in the simulator, and have not found a way to distribute this app. When attempting to run on the simulator, I get this issue: Please try again later. Appex bundle at /Users/jason/Library/Developer/CoreSimulator/Devices/09A70160-4F4F-4F5E-B679-F6F7D876D7EF/data/Library/Caches/com.apple.mobile.installd.staging/temp.6OAEZp/extracted/LaunchBar.app/PlugIns/LaunchBarShareExtension.appex with id co.swiftfox.LaunchBar.ShareExtension specifies a value (com.apple.share-services) for the NSExtensionPointIdentifier key in the NSExtension dictionary in its Info.plist that does not correspond to a known extension point. When trying to archive an upload to test flight, I get this similar error: Invalid Info.plist value. The value for the key 'DTPlatformName' in bundle LaunchBar.app/PlugIns/LaunchBarShareExtension.appex is invalid. (ID: 207610c7-b7e1-48be-959b-22a43cd32d16) The app is for visionOS only - which I'm thinking might be the problem? The share extension is "Designed For iPhone" and requires me to include iPhone as a run destination. In the worst case I can build an iPhone UI for the app but I'd rather not, as it is very specific to visionOS. Has anyone successfully launched a share extension on a visionOS only app? I have an iPad app with a share extension that shows up fine on visionOS, but the issue seems to be specifically with visionOS only apps.
