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?

Hi, 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. Minimal reproducible code: var body: some View { RealityView { content in let cube = ModelEntity( mesh: .generateBox(size: 0.3), materials: [SimpleMaterial(color: .red, isMetallic: false)] ) cube.setPosition(SIMD3<Float>(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!

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

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!

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) } } }

Is it possible to retrieve the position and orientation of a window that is opened in an immersive space? The following code: struct MyWindow: View { var body: some View { VStack { Text("Hello") } .onGeometryChange3D(for: Point3D.self) { proxy in try! proxy .coordinateSpace3D() .convert(value: Point3D.zero, to: .worldReference) } action : { point in print(point) } } } seems to work for the position, but I also need the orientation.

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!

This is a very exciting feature in 26.4 beta. But from the document, it seems can only integrate with NVIDIA CloudXR™ SDK. I'm wondering if it's possible to use this tool to stream immersive video from Mac to Vision Pro?

Hello, I was wondering how I can initialize an ImageAnchoringSource using https://developer.apple.com/documentation/realitykit/anchoringcomponent/imageanchoringsource/init(_:) When I construct one using a URL, it doesn't seem to be tracked and I see in the following when I debug print the component: ▿ 0 : AnchoringComponent ▿ target : Target ▿ referenceImage : 1 element ▿ from : ImageAnchoringSource ▿ url : Optional<URL> ▿ some : file:///var/mobile/Containers/Data/Application/D1126EA0-A1D7-468F-A40C-8578B7F5BDDF/Library/Caches/CodeCache/0E457AA7-2195-48B9-9DD4-58CEB9397F69.png - _url : file:///var/mobile/Containers/Data/Application/D1126EA0-A1D7-468F-A40C-8578B7F5BDDF/Library/Caches/CodeCache/0E457AA7-2195-48B9-9DD4-58CEB9397F69.png - _parseInfo : nil - _baseParseInfo : nil - name : nil - group : nil ▿ trackingMode : TrackingMode - trackingMode : 2 Is there a specific format for the parseInfo? When I use the same image to make an image anchoring source by group and name in AR Resources, it is tracked. Thank you!

I have an iOS app that uses RealityView to display some models and interact with them, and the app uses regular iOS app navigations, then a challenge I'm facing is how to maintain multiple RealityView on multiplescreens. For example Screen A has a RealityView, and then I navigate to Screen B (also has a RealityView) using stack based navigation, when I do so I got a crash -[MTLDebugRenderCommandEncoder validateCommonDrawErrors:]:5970: failed assertion `Draw Errors Validation Fragment Function(fsRealityPbr): argument envProbeTable[0] from Buffer(7) with offset(0) and length(16) has space for 16 bytes, but argument has a length(864). Fragment Function(fsRealityPbr): incorrect type of texture (MTLTextureType2D) bound at Texture binding at index 20 (expect MTLTextureTypeCubeArray) for envProbeDiffuseArray[0]. Interestingly this crash only happens when debugging with Xcode, not happens when the app runs on its own. I'm not sure what I'm doing is anti-pattern or it's some Xcode debugging limitation.

Hi, I would like clarification on whether the new hover effects feature introduced in vision os 26 supported pinch gestures through the psvr 2 controllers. In your sample application, I found that this was not working. Pulling the trigger on the controller whilst looking at the 3d object did not activate the hover effect spatial event in the sample application. (The object is showing the highlight though), only pinch clicking with my fingers seem to be registering/triggering the spatial event. I am using Vision OS 26.3 This is inconsistent with how the psvr2 controller behaves on swift ui views and ui view elements, where the trigger press does count as a button click. The sample I used was this one: https://developer.apple.com/documentation/compositorservices/rendering_hover_effects_in_metal_immersive_apps

Hi, Is there a resource or sample code about how to draw an outline around a mesh in RealityKit? Typically, this is useful for visualizing a selection, like in Reality Composer Pro. How to achieve such effect? A shader material? A post-process effect in ARView or RealityRenderer? Methods such as duplicating the entity mesh, scaling it, and using material.faceCulling = .front did not look good in my experiments. Thank you.

Hi, I’m wondering whether RealityKit has its own scene management system, since it uses ARView (backed by ARKit) to present AR content. Does RealityKit manage scenes independently, or does it rely entirely on ARKit’s scene handling? Thank you.

Hi, we have been working on an application that attaches a hand model to the users hands. Apple provides an animating hand models in visionOS project that is a useful starting point. https://developer.apple.com/documentation/visionOS/animating-hand-models-in-visionOS We have been trying to create our own hand model to attach but have had some issues with how it is attaching to the hand. For our hand model we want to include the forearm all the way up to the users elbow. I have attached a sample project of what our code currently looks like so you can run it. Just select show immersive space to attach the models. The left hand model is the space glove that we were trying to mirror. The right hand model is our model that we have been using. I have mapped each of the joints to the pertaining joint name on our model. The first issue we are having seems to be based around the placement of the forearm. It attaches itself at the wrist. The second issue seems to be around rotation. Our team is looking for some guidance on what needs to change in order to map this model correctly. Thanks in advance!

I use ARKit for motion tracking. I get the skeleton joint coordinates and use them for animation. I didn't make any changes to the code, but I updated the iOS version from 18 to 26, and modelTransform now always returns nil. https://developer.apple.com/documentation/arkit/arskeleton3d/modeltransform(for:) For example bodyAnchor.skeleton.modelTransform(for: .init(rawValue: "head_joint")) bodyAnchor is ARBodyAnchor. I see the default skeleton on the screen, but now I can't get the coordinates out of it. I'm using an example from Apple's WWDC presentation. https://developer.apple.com/documentation/arkit/capturing-body-motion-in-3d Are there any changes in the API? Or just bug?

When rendering an equirectangular video on a sphere using VideoMaterial and MeshResource.generateSphere(), there is a visible black seam line running vertically on the sphere. This appears to be at the UV seam where the texture coordinates wrap from 1.0 back to 0.0. The same video file plays without any visible seam in other 360° video players on Vision Pro, so the issue is not with the video content itself. Here is the relevant code: private func createVideoSphere(content: RealityViewContent, player: AVPlayer) { let sphere = MeshResource.generateSphere(radius: 1000) let material = VideoMaterial(avPlayer: player) let entity = ModelEntity(mesh: sphere, materials: [material]) entity.scale *= .init(x: -1, y: 1, z: 1) // Flip to render on inside content.add(entity) player.play() } The setup is straightforward: MeshResource.generateSphere(radius: 1000) generates the sphere mesh VideoMaterial(avPlayer:) provides the video texture X scale is flipped to -1 so the texture renders on the inside of the sphere The video is a standard equirectangular 360° MP4 file What I've tried: I attempted to create a custom sphere mesh using MeshDescriptor with duplicate vertices at the UV seam (longitude 0°/360°) to ensure proper UV continuity. However, VideoMaterial did not render any video on the custom mesh (only audio played), and the app eventually crashed. It seems VideoMaterial may have specific mesh requirements. Questions: Is the black seam a known limitation of MeshResource.generateSphere() when used with VideoMaterial for 360° video? Is there a recommended way to eliminate this UV seam — for example, a texture addressing mode or a specific mesh configuration that works with VideoMaterial? Is there an official sample project or code example for playing 360° equirectangular video in a fully immersive space on visionOS? That would be extremely helpful as a reference. Any guidance would be greatly appreciated. Thank you!

My visionOS 26.3 app displays a diorama-like scene in a RealityView in a mixed immersive space, about 1 meter square, with view attachments floating above the scene. Each view attachment fades out after user interaction, by animating the view's opacity. What I'm observing is that depending on the position of a view attachment relative to the scene and the camera, an unwanted cutout effect is observed (presumably because of draw order issues), as shown in the right column in the screenshots below. YouTube video link of these sequences: https://youtu.be/oTuo0okKCkc (19 seconds) My question: How does visionOS determine the view attachment draw order relative to the RealityView scene? If I better understood how the draw order is determined, I could modify my scene to ensure that the view attachments were always drawn after the scene, fixing the unwanted cutout effect. I've successfully used ModelSortGroupComponent to control the draw order of entities within the RealityView scene, but my understanding is that this approach cannot be used with view attachments. I've submitted FB22014370 about this issue. Thank you.

I have a simple visionOS app that creates an Entity, writes it to the device, and then attempts to load it. However, when the entity file get overwritten, it affects the ability for the app to load it correctly. Here is my code for saving the entity. import SwiftUI import RealityKit import UniformTypeIdentifiers struct ContentView: View { var body: some View { VStack { ToggleImmersiveSpaceButton() Button("Save Entity") { Task { // if let entity = await buildEntityHierarchy(from: urdfPath) { let type = UTType.realityFile let filename = "testing.\(type.preferredFilenameExtension ?? "bin")" let documentsURL = FileManager.default.urls(for: .documentDirectory, in: .userDomainMask)[0] let fileURL = documentsURL.appendingPathComponent(filename) do { let mesh = MeshResource.generateBox(size: 1, cornerRadius: 0.05) let material = SimpleMaterial(color: .blue, isMetallic: true) let modelComponent = ModelComponent(mesh: mesh, materials: [material]) let entity = Entity() entity.components.set(modelComponent) print("Writing \(fileURL)") try await entity.write(to: fileURL) } catch { print("Failed writing") } } } } .padding() } } Every time I press "Save Entity", I see a warning similar to: Writing file:///var/mobile/Containers/Data/Application/1140E7D6-D365-48A4-8BED-17BEA34E3F1E/Documents/testing.reality Failed to set dependencies on asset 1941054755064863441 because NetworkAssetManager does not have an asset entity for that id. When I open the immersive space, I attempt to load the same file: import SwiftUI import RealityKit import UniformTypeIdentifiers struct ImmersiveView: View { @Environment(AppModel.self) private var appModel var body: some View { RealityView { content in guard let type = UTType.realityFile.preferredFilenameExtension else { return } let documentsURL = FileManager.default.urls(for: .documentDirectory, in: .userDomainMask)[0] let fileURL = documentsURL.appendingPathComponent("testing.\(type)") guard FileManager.default.fileExists(atPath: fileURL.path) else { print("❌ File does not exist at path: \(fileURL.path)") return } if let entity = try? await Entity(contentsOf: fileURL) { content.add(entity) } } } } I also get errors after I overwrite the entity (by pressing "Save Entity" after I have successfully loaded it once). The warnings that appear when the Immersive space attempts to load the new entity are: Asset 13277375032756336327 Mesh (RealityFileAsset)URL/file:///var/mobile/Containers/Data/Application/1140E7D6-D365-48A4-8BED-17BEA34E3F1E/Documents/testing.reality/Mesh_0.compiledmesh failure: Asset provider load failed: type 'RealityFileAsset' -- RERealityArchive: Failed to open load stream for entry 'assets/Mesh_0.compiledmesh'.

I want to: Run ARKit on the main rear camera, and while it's running shoot high resolution pictures on the wide camera, without disturbing the AR tracking. Is this possible?
