Hi all, I'm running into an issue with an app that previously worked fine on device using visionOS 2.0. After updating to visionOS 26, the same code runs fine in the simulator but crashes on the device with the following error: -[MTLDebugComputeCommandEncoder _validateThreadsPerThreadgroup:]:1330: failed assertion `(threadsPerThreadgroup.width(32) * threadsPerThreadgroup.height(32) * threadsPerThreadgroup.depth(1))(1024) must be <= 832. (kernel threadgroup size limit)` Is there any documented way to check or increase the allowed threadsPerThreadgroup size on Apple Vision Pro? Or any recommended workaround for this regression? Thanks in advance!

A recent WWDC session "Learn about Apple Immersive Video technologies" showed a Apple Spatial Audio Format Panner plugin for Pro Tools. The presenter stated that it's available on a per-user license. Where can users access this?

Apple Vision Pro support issue. The app contains the following UIRequiredDeviceCapabilities values, which aren’t supported in visionOS: [arkit]. When I try and distribute a build to the AppStore in Xcode, it comes up with this message, I have not selected Vision Pro as part of my build, can anyone please help? Thanks!

We got very excited when we saw support for the PSVR2 on WWDC! Particularly interesting is WebXR to us, so we got the controllers to give it a try. Unfortunately they only register as gamepads in the navigator but not as XRInputDevice's We went through the experimental flags and didn't find something that is directly related. Is there a flag we missed? If not, when do you have PSVR2 support planned for WebXR?

Starting in visionOS 26, users can snap windows to surfaces. These windows are locked in place and are later restored by visionOS. We can access the snapped data with surfaceSnappingInfo docs. Users can also lock a free-floating (unsnapped) window from a context menu in the window controls. Is there a way to tell when a window has been locked without being snapped to a surface?

In Apple Vision Pro, I want to implement a HUD page similar to the one in Medivis' SuricalAR product (i.e. the UI is fixed on the screen field of view rather than in space). How should I do it?

With the new ImagePresentationComponent in visionOS 26, how can text/overlays be shown on top of the image as seen in the Spatial Gallery app?

Any way to extend the video recording time in Reality Composer Pro from 3:00 to any longer value, such as editing preferences in Terminal or other workaround? Is there any way to use the strap and a USB-C cable as a live video stream input source that would mirror to Quicktime or some other video capture tool? I am assuming there is no online documentation or user manual for the strap, but please correct me if I'm wrong. Thank you.

So I am exporting a .usdc file from blender that already has some morph animations. The animations play well in blender but when I export I cannot seem to play them in RealityKit or RCP. Entity.availableAnimations is an empty array. Not of the child objects in the entity hierarchy has an animation library component with it. Maybe I am exporting it wrong but I tried multiple combinations but doesn't seem to work. Here are my export settings in blender The original file I purchased is an FBX file that has the animation but when I try to directly get it in RealityConverter it doesn't seem to play animations.

I need a MeshResource from ModelEntity to generate a box collider, but ModelEntity fails to load USDZ files from the Reality Composer Pro (RCP) bundle. This code works for loading an Entity: // Successfully loads as generic Entity previewEntity = try await Entity(named: fileName, in: realityKitContentBundle) But this fails when trying to load as ModelEntity: // Fails to load as ModelEntity modelEntity = try await ModelEntity(named: fileName, in: realityKitContentBundle) I found this thread mentioning: "You'll likely go from USDZ to Entity which contains a MeshResource when you load/init the USDZ file." But it doesn't explain ​how to actually extract the MeshResource. Could anyone advise: How to properly load USDZ files as ModelEntity from RCP bundles? How to extract MeshResource from a successfully loaded Entity? Alternative approaches to generate box colliders if direct extraction isn't possible? Sample code for extraction or workarounds would be greatly appreciated!

Hey everyone, I’m developing an app for visionOS where I need to display the Apple Vision Pro’s current IP address. For this I’m using the following code, which works for iOS, macOS, and visionOS in the simulator. Only on a real Apple Vision Pro it’s unable to extract an IP. Could it be that visionOS currently doesn’t allow this? Have any of you had the same experience and found a workaround? var address: String = "no ip" var ifaddr: UnsafeMutablePointer<ifaddrs>? = nil if getifaddrs(&ifaddr) == 0 { var ptr = ifaddr while ptr != nil { defer { ptr = ptr?.pointee.ifa_next } let interface = ptr?.pointee let addrFamily = interface?.ifa_addr.pointee.sa_family if addrFamily == UInt8(AF_INET) { if let name: Optional<String> = String(cString: (interface?.ifa_name)!), name == "en0" { var hostname = [CChar](repeating: 0, count: Int(NI_MAXHOST)) getnameinfo(interface?.ifa_addr, socklen_t((interface?.ifa_addr.pointee.sa_len)!), &hostname, socklen_t(hostname.count), nil, socklen_t(0), NI_NUMERICHOST) address = String(cString: hostname) } } } freeifaddrs(ifaddr) } return address } Thanks in advance for any insights or tips! Best Regards, David

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.

Hello I want to ask you why special scenes feature not available for iPhone 11 in iOS 26.

Based on the "Build immersive web experiences with WebXR"-Video for visionOS there is no way to disable the consent prompts for entering an immersive experience or consent hand-tracking. For the microphone it's possible to "greenlight" specific websites for mic input, which works great. I'd welcome it, if it were possible to add specific websites in the settings, in which those consent dialogs aren't shown each time. In my opinion, the user interaction through a button that launches the experience would be sufficient to not disorient.

I'm using a class with tangents to render on RealityKit for VisionOS but in Vision26 it cause a crash on App and there not documentation how implement cp_drawable_compute_projection I have tried a few options but without success. Could you help me to implement it ? The part of code is: return drawable.views.map { view in let userViewpointMatrix = (simdDeviceAnchor * view.transform).inverse let projectionMatrix = ProjectiveTransform3D( leftTangent: Double(view.tangents[0]), rightTangent: Double(view.tangents[1]), topTangent: Double(view.tangents[2]), bottomTangent: Double(view.tangents[3]), nearZ: Double(drawable.depthRange.y), farZ: Double(drawable.depthRange.x), reverseZ: true ) let screenSize = SIMD2(x: Int(view.textureMap.viewport.width), y: Int(view.textureMap.viewport.height)) return ModelRendererViewportDescriptor(viewport: view.textureMap.viewport, projectionMatrix: .init(projectionMatrix), viewMatrix: userViewpointMatrix * translationMatrix * rotationMatrix * scalingMatrix * commonUpCalibration, screenSize: screenSize) }

Dear App Review Team, We are raising serious concerns regarding the ongoing review process for the app (App ID: 6737148404), which has once again been escalated to the App Review Board—just days after the previous issue was finally resolved. We submitted a new build on June 18 containing a standard feature update. The app entered "In Review" promptly, but after 3 days with no communication, it has now been escalated to the board again, likely. This pattern is deeply troubling. What’s particularly alarming is that it appears the current reviewer lacks the necessary context or understanding of the app, and instead of engaging with us or taking ownership of the review, they’ve defaulted to escalating it without providing any rationale or feedback. This repeated hand-off to the board without accountability or explanation is effectively grinding our release process to a halt. Based on past experience, we suspect we are now waiting for another board meeting early next week—which means yet another week lost to silence and uncertainty. This is not a scalable or sustainable process. This is one of the top performing apps on visionOS, and yet every iteration—regardless of how minor—is delayed by escalations and inaction. These delays are damaging to our business, destabilizing to our user experience, and increasingly eroding our trust in the App Review process. We urgently request: Immediate clarity on the current review status A direct line of communication with someone accountable for the review An explanation as to why nearly every update requires board involvement We’ve complied fully with all App Store guidelines. All standard support channels have already been exhausted without resolution. This cycle must change. We are ready and willing to work collaboratively, but we need responsiveness and consistency from Apple in return. App ID: 6737148404

Looking at the superclass of CPImmersiveScene is surprisingly is a UIWindowScene. Is this intentional? Should I treat it as a window scene, and provide an UIWindow for it? Or is it only an implementation detail for managing the internal CPSceneLayerEventWindow and UITextEffectsWindow?

Hello all, I saw this interesting VisionOS app: https://apps.apple.com/us/app/splitscreen-multi-display/id6478007837 I was wondering if there was any documentation on the Swift APIs that were used to create this app.

I want the effect of the model to be similar to the HoverEffect effect, but not by staring with the eyes. Instead, by clicking a button elsewhere, the corresponding model will appear highlighted，How can it be achieved

Hello, I'm currently developing for visionOS using Xcode's latest beta version. I have a question regarding Widget Previews for visionOS 26: When I create a new Widget Extension target directly from a visionOS project, the generated code does not include the #Preview macro. Following the documentation, I manually added the #Preview macro to a Widget created within a visionOS project, but Xcode then displays an error stating that "This platform does not support previewing widgets." My interpretation is that Widget Previews are currently not supported for Widgets created specifically for visionOS in this beta version. Is this understanding correct? Or am I missing a specific way to implement previews for visionOS Widgets, or is there a particular project setting I might have overlooked? Any clarification or guidance on this matter would be greatly appreciated. Thank you.
