I'm experiencing an issue where all RealityView content disappears when the user selects "Lock In Place" from the window management menu (long press on close button). "Follow Me" works correctly and this happens in Testflight builds only not reproducible when I run locally I have reproduced this with a minimal project containing nothing but a simple red cube — no custom anchors, no app state, no dependencies. Steps to Reproduce: Open an ImmersiveSpace A red cube is placed 1m in front of the user via RealityView Long press the X button on any floating window Select "Lock In Place" The cube disappears immediately Expected: Cube remains visible after window is locked Actual: Cube disappears. Note: "Follow Me" does NOT reproduce this issue. Minimal reproducible code: struct ImmersiveView: View { var body: some View { RealityView { content in let cube = ModelEntity( mesh: .generateBox(size: 0.3), materials: [SimpleMaterial(color: .red, isMetallic: false)] ) cube.setPosition(SIMD3(0, 1.5, -1), relativeTo: nil) content.add(cube) } } } Device: Apple Vision Pro visionOS version: Vision OS 26.2 (23N301) Xcode version: Version 26.3 (17C529) Is this a known issue? Is there a recommended workaround to preserve RealityView content during Lock In Place transitions? Thank you!

Area: visionOS 26.4 · AVFoundation · AVCapture · External/UVC video Classification: Suggestion / API Enhancement Request (also: Incorrect/Missing Documentation) Device / OS: Apple Vision Pro, visionOS 26.x. Xcode 26.4.1, XROS26.4.sdk. Summary On visionOS, a third-party app cannot display two UVC USB cameras (connected through a powered USB-C hub) at the same time. Every AVFoundation path that would enable this on iPadOS is either unavailable or fails at runtime on visionOS, and there is no public non-AVFoundation fallback (no IOUSBHost, no DriverKit, no usable CoreMediaIO, no MFi path for generic UVC devices). This is a real capability gap relative to iPadOS and macOS, and Camo Studio on iPadOS (App Store ID 6450313385) demonstrates the two-camera USB-hub use case is legitimate and valuable for spatial-video/hybrid-capture workflows on Vision Pro. Steps to reproduce Connect a powered USB-C hub to Apple Vision Pro with two UVC webcams attached. Build a visionOS app that uses AVCaptureDevice.DiscoverySession(deviceTypes: [.external], …). Observe: both cameras are discovered and enumerate as distinct AVCaptureDevices. Attempt A — two independent sessions: Create two independent AVCaptureSessions, each with one AVCaptureDeviceInput and one AVCaptureVideoDataOutput, start both. Result: only one session delivers sample buffers. The other stalls silently with no error and no interruption notification. Attempt B — AVCaptureMultiCamSession with manual connections (the pattern that works on iPadOS 18+): Result: code does not compile. In XROS26.4.sdk: AVCaptureInputPort is API_UNAVAILABLE(visionos) (AVCaptureInput.h) AVCaptureInput.ports is API_UNAVAILABLE(visionos) AVCaptureDeviceInput.portsWithMediaType:sourceDeviceType:sourceDevicePosition: is API_UNAVAILABLE(macos, visionos) Therefore AVCaptureConnection(inputPorts:output:) cannot be constructed. AVCaptureMultiCamSession itself is declared API_AVAILABLE(… visionos(2.1)), which is misleading because without input-port access the manual-connection path the class requires is unreachable. Expected behavior Either of the following would resolve this, in order of preference: Expose the missing API surface on visionOS. Make AVCaptureInputPort, AVCaptureInput.ports, and AVCaptureDeviceInput.portsWithMediaType:sourceDeviceType:sourceDevicePosition: available on visionOS so the documented iPadOS multi-cam pattern compiles and runs. AVCaptureMultiCamSession is already declared available — the supporting API surface should match. Allow two concurrent plain AVCaptureSessions to each own a distinct external AVCaptureDevice. Each session binds a different hardware device, and the current serialization appears to be a software policy rather than a hardware constraint (a powered hub has bandwidth for both). Document the limit explicitly and surface a clear error or interruption reason on the stalled session so apps can fail loudly instead of appearing to work. Actual behavior AVCaptureMultiCamSession advertises visionos(2.1) availability but the APIs required to wire its connections are marked unavailable on visionOS. Two concurrent AVCaptureSessions silently deliver frames to only one session; no error is reported on the other. There is no public alternative framework on visionOS for raw UVC access to work around this: IOUSBHost.framework — not present in XROS26.4.sdk DriverKit — not present in XROS26.4.sdk IOKit — ships a stub (IOKit.tbd); no public USB device interfaces CoreMediaIO — headers are an apinotes stub on visionOS ExternalAccessory — MFi-only; generic UVC devices don't enumerate This means there is no public path, AVFoundation or otherwise, for a third-party visionOS app to display two UVC cameras at once. Impact / use cases Apple Vision Pro is uniquely suited to multi-camera monitoring and capture workflows — spatial creators, broadcast/AV producers, multi-angle reference during immersive authoring, clinical and field-recording use cases, and apps that combine a primary UVC cinema camera with a secondary UVC reference/overview angle. iPadOS already supports this via AVCaptureMultiCamSession (demonstrated shipping by Camo Studio). The current visionOS limitation pushes these workflows back to iPad or macOS and undermines Vision Pro's positioning as a pro capture/monitor environment. References iPadOS reference implementation: Apple sample Displaying Video From Connected Devices + AVCaptureMultiCamSession with manual AVCaptureConnection wiring — works on iPadOS 18+ with two UVC cameras via a powered hub. Shipping precedent: Camo Studio — two simultaneous UVC cameras via USB hub on iPad — https://apps.apple.com/us/app/camo-studio-stream-record/id6450313385 visionOS 26.4 SDK headers cited above (AVCaptureInput.h, AVCaptureSession.h).

When a NavigationSplitView detail column shows a View that uses .searchable(text: $searchText, placement: .navigationBarDrawer), the search bar extends under the sidebar region, on the first View render only. After any event that triggers a View refresh (such as switching away and back to the View, editing the search text, or resizing the window) the search field is positioned correctly in the detail column’s navigation area. var body: some View { NavigationSplitView { List { Text("Sidebar") } .navigationTitle("Sidebar") } detail: { Text("Detail") .navigationTitle("List") .searchable( text: $searchText, placement: .navigationBarDrawer ) } } FB22559713 has been opened.

When using the new RealityKit Manipulation Component on Entities, indirect input will never translate the entity - no matter what settings are applied. Direct manipulation works as expected for both translation and rotation. Is this intended behaviour? This is different from how indirect manipulation works on Model3D. How else can we get translation from this component? visionOS 26 Beta 2 Build from macOS 26 Beta 2 and Xcode 26 Beta 2 Attached is replicable sample code, I have tried this in other projects with the same results. var body: some View { RealityView { content in // Add the initial RealityKit content if let immersiveContentEntity = try? await Entity(named: "MovieFilmReel", in: reelRCPBundle) { ManipulationComponent.configureEntity(immersiveContentEntity, allowedInputTypes: .all, collisionShapes: [ShapeResource.generateBox(width: 0.2, height: 0.2, depth: 0.2)]) immersiveContentEntity.position.y = 1 immersiveContentEntity.position.z = -0.5 var mc = ManipulationComponent() mc.releaseBehavior = .stay immersiveContentEntity.components.set(mc) content.add(immersiveContentEntity) } } }

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?

Hi everyone, I’m a mixed reality designer currently building visionOS experiences (RealityKit + SwiftUI), and I’m working on a course at Arizona State University where we develop a project in response to a real-world client. I’m looking to collaborate with someone in the visionOS ecosystem who would be open to sharing a simple prompt or brief (nothing confidential), which I can use to create a proposal response. The outcome would include: Spatial concept + storyboard Interaction design direction Rough scope, timeline, and team structure Optional small prototype in visionOS The goal on my side is to better understand how spatial work is framed and communicated in real-world scenarios, especially within Apple’s ecosystem. The ask is very lightweight: 1–2 short check-ins during April or async feedback via email A bit about my work: Built Spatial Synesthesia for Apple Vision Pro Eye tracking interaction that isolates instruments in a live orchestral mix based on color perception Working with computer vision and spatial anchoring in Unity and visionOS Focused on perception-driven interaction and minimal UI systems If you’re a developer, designer, or part of a small studio working in visionOS and this sounds interesting, I’d love to connect. Thanks in advance. Leo

Hi everyone, I’m currently using the visionOS Enterprise APIs, and I noticed in the official documentation that: However, I couldn’t find any clear instructions on how to actually renew the license. What is the correct process to renew a visionOS Enterprise API license? Do I need to submit a new entitlement request again to renew? Is there any official step-by-step guide or documentation for renewal? Any advice or shared experience would be greatly appreciated 🙏 Thank you!

The error: When building a RealityKitContent package that contains a USDZ file exported from Blender, Xcode throws the following error: error: [xrsimulator] Exception thrown during compile: Cannot get rkassets content for path .../RealityKitContent.rkassets because 'The file "RealityKitContent.rkassets" couldn't be opened because you don't have permission to view it.' error: Tool exited with code 1 The error message mentions "permission" — but permissions are not the issue. This appears to be a misleading error from realitytool masking a USD validation failure. What I've ruled out File permissions — all files are -rw-r--r--, user has Read & Write on the folder Extended attributes / quarantine flag — other files with the same @ flag work fine Corrupted archive — unzip -t confirms the USDZ is valid (board.usdc + textures) Stale build cache — deleted DerivedData and com.apple.DeveloperTools cache, no change Key observations The same file builds successfully on my colleague's machine running identical Xcode 26.3 - MacOS 26.3 Other USDZ files in the same .rkassets bundle (downloaded from Sketchfab, or created in Reality Composer Pro) compile without any issue. Only USDZ files exported directly from Blender are affected. When the file is placed in Bundle.main and loaded via Entity(named:in:.main), it works perfectly — no errors Reality Converter flags the file with two errors: UsdGeomPointInstancers not allowed, and root layer must be .usdc with no external dependencies The confusing part: the same file compiles fine on an identical Xcode 26.3 setup and importing method. This suggests either a machine-specific difference in Xcode's validation behavior, or a cached .reality bundle on my colleague's machine that isn't being recompiled. Current workaround: Loading from Bundle.main instead of the RealityKitContent package bypasses realitytool entirely and works, but loses Reality Composer Pro integration: if let entity = try? await Entity(named: "test", in: Bundle.main)

I first started using the SwiftUI pushWindow API in visionOS 26.2, and I've reported several bugs I discovered, listed below. Under certain circumstances, pushed window relationships may break, and this behavior affects all other apps, not just the app that caused the problem, until the next device reboot. In other cases, the system may crash and restart. (FB21287011) When a window presented with pushWindow is dismissed, its parent window reappears in the wrong location (FB21294645) Pinning a pushed window to a wall breaks pushWindow for all other apps on the system (FB21594646) pushWindow interacts poorly with the window bar close app option (FB21652261) If a window locked to a wall calls pushWindow, the original window becomes unlocked (FB21652271) If a window locked in place calls pushWindow and the pushed window is closed, the system freezes (FB21828413) pushWindow, UIApplication.open, and a dismissed immersive space result in multiple failures that require a device reboot (FB21840747) visionOS randomly foregrounds a backgrounded immersive space app with a pushed window's parent window visible instead of the pushed window (FB21864652) When a running app is selected in the visionOS home view, windows presented with pushWindow spontaneously close (FB21873482) Pushed windows use the fixed scaling behavior instead of the dynamic scaling behavior I'm posting the issues here in case this information is helpful to other developers. I'd also like to hear about other pushWindow issues developers have encountered, so I can watch out for them. Questions: I've discovered that some of the issues above can be partially worked around by applying the defaultLaunchBehavior and restorationBehavior scene modifiers to suppress window restoration and locking, which pushWindow appears to interact poorly with. Are there other recommended workarounds? I've observed that the Photos and Settings apps, which predate the pushWindow API, are not affected by the issues I reported. Are there other more reliable ways I could achieve the same behavior as pushWindow without relying on that API? I'd appreciate any guidance Apple engineers could provide. Thank you.

After I updated to visionOS 26.4, I noticed my website environment would suddenly turn off occasionally while I was watching YouTube in Safari. My M2 AVP was still warm after the update. Is turning off a website environment expected behavior when the headset gets warm (e.g., perhaps to reduce load)? If not, anyone have an idea this might happen?

After updating to visionOS 26.4, I went to Safari's Feature Flags page to reenable Website environment, and I found the Website environment switch had been moved from the top and into the list of switches below. In its place is "Immersive API". I could not find any documentation on this. Anyone know what it is for or can point me to documentation?

Hi everyone, I'm new to visionOS development. I'm trying to create a physics-based scene (with gravity) where users can pick up and move objects on a workbench. I am struggling with physics interactions during the drag gesture: Kinematic Mode: If I switch to .kinematic during the drag, the object moves smoothly but clips through other objects (no collisions). Dynamic Mode: I tried keeping it .dynamic and applying linear velocity toward the hand position, but the movement feels laggy and unresponsive. Hybrid Approach: I tried switching to .kinematic during DragGesture.onChange and back to .dynamic on collision, but this causes the entity to jitter/shake violently when touching other objects. Has anyone found a clean way to drag objects while maintaining solid collisions. Thanks for your help!

When i use the MFMailComposeViewController in visionOS, there is no cancel button for the controller. The button at the bottom closes the app. Is anyone else experiencing this? if([MFMailComposeViewController canSendMail]) { MFMailComposeViewController* controller = [[MFMailComposeViewController alloc] init]; controller.mailComposeDelegate = (id <MFMailComposeViewControllerDelegate>)view; [controller setToRecipients:toAddresses]; [controller setSubject:subject]; [controller setMessageBody:body isHTML:isHtml]; [view presentViewController:controller animated:YES completion:nil]; }

Hello, I know that Apple bans user from accessing to raw gaze data like gaze vector (x,y,z) or eye position. But when you do research on gaze data, how did you collect them from vision pro? Is there any App to solve this problem?

Hi, I'm running the Spatial Rendering App sample on a Macbook Pro running 26.4 Beta and the Vision Pro running visionOS 26.3.1. Handoff and SharePlay are on, both devices are on the same Apple ID and network, and SharePlay screen sharing works fine between the two devices. However, when calling openImmersiveSpace, the device picker fails to present and no devices are found. Errors from console: ((processConfiguration != nil && configuration != nil) || (processConfiguration == nil && configuration == nil)) - .../ExtensionKit/Source/HostViewController/Internal/EXHostSessionDriver.m:80: `processConfiguration` and `configuration` must be both non-nil or both nil Unable to obtain a task name port right for pid 638: (os/kern) failure (0x5) Unable to present an ImmersiveSpace for Scene id 'Compositor Services' Is this a known bug or I'm I missing something? Thanks!

Thank you again for pushing the web forward in VisionOS 2, super exciting! The latest WWDC24 video touched on VR experiences for VisionOS2.0 using WebXR, however there was no mention of passthrough AR experiences. Samples such as this one are not supported: https://immersive-web.github.io/webxr-samples/immersive-ar-session.html In Settings > Safari, there is a feature flag for the AR WebXR module, but enabling it did not seem to change anything. Is this the expected behavior at this time? Any developer preview(s) we could try?

Use case proposal: immersive mental visualisation and manifestation experiences on visionOS I'd like to open a discussion around a use case I believe is currently missing from the visionOS ecosystem

I asked AI to build a realistic ocean shader for a VisionOS project using RealityKit. It gave a bunch instructions and asked me to connect large amount of nodes for the ShaderGraph in the Reality Composer Pro. I am just wondering if AI can help to generate the Metal shader code directly, or build the ShaderGraph nodes for me automatically.

Hi Apple Developer Forums, I'm developing a visionOS video streaming app that uses a custom immersive cinema experience with RealityKit. I have a question about enabling video reflections in an immersive environment. My Current Implementation I'm using VideoMaterial with AVPlayer to display video on a ModelEntity plane in an immersive space: // Create screen mesh let screenMesh = MeshResource.generatePlane( width: VideoTheater.screenWidth, height: VideoTheater.screenHeight, cornerRadius: 0.0 ) let screenEntity = ModelEntity(mesh: screenMesh) // Apply VideoMaterial with AVPlayer screenEntity.model?.materials = [VideoMaterial(avPlayer: player)] The video renders correctly in the immersive space, but I don't see any video reflections on surrounding surfaces. Apple's Documentation Approach According to the documentation at https://developer.apple.com/documentation/visionos/enabling-vid eo-reflections-in-an-immersive-environment, the recommended approach uses: AVPlayerViewController for video playback dockingRegion modifier to specify where the video should appear The system automatically handles reflections My Question Is using AVPlayerViewController with dockingRegion the only way to get video reflections in an immersive environment? Or is it possible to enable reflections when using VideoMaterial directly with RealityKit's ModelEntity? My app requires a custom immersive cinema experience with: Custom screen positioning and scaling Danmaku (bullet comments) overlay Custom gesture controls HDR/Dolby Vision support Switching to AVPlayerViewController would require significant architectural changes, so I'd prefer to keep my current VideoMaterial approach if reflections can be enabled somehow. If VideoMaterial cannot produce reflections, are there any alternative approaches to achieve diffuse video reflections with a custom RealityKit setup? Environment visionOS 2.x RealityKit AVPlayer with custom resource loader (for DASH streams) Thank you for any guidance!
