Hello, I am currently working on a Unity project for the Apple Vision Pro. I would like to have people passing in front of the virtual objects occlude the virtual objects that are behind. Something similar to this: https://developer.apple.com/documentation/arkit/occluding-virtual-content-with-people I could unfortunately not find any documentation about this. Is it possible to implement body segmentation or occlusion on the Apple Vision Pro? If it's not currently supported, are there plans to add it? Any ideas on how to achieve this with existing tools? Thanks! Mehdi

Here is the code snippets. struct RealityViewTestView: View { @State private var texts: [String] = [] var body: some View { RealityView { content, attachments in } update: { content, attachments in for text in texts { if let textEntity = attachments.entity(for: text) { textEntity.position.x = Float.random(in: -0.1...0.1) content.add(textEntity) } } } attachments: { ForEach(texts, id: \.self) { text in Attachment(id: text) { Text(text) .padding() .glassBackgroundEffect() } } } .toolbar { ToolbarItem { Button("Add") { texts.append(String(UUID().uuidString.prefix(6))) } } ToolbarItem { Button("Remove") { texts.remove(at: Int.random(in: 0..<texts.count)) } } } } } struct RealityViewTestView: View { @State private var texts: [String] = [] @State private var entities: [Entity] = [] var body: some View { RealityView { content, attachments in } update: { content, attachments in // for text in texts { // if let textEntity = attachments.entity(for: text) { // textEntity.position.x = Float.random(in: -0.1...0.1) // content.add(textEntity) // } // } for entity in entities { content.add(entity) } } attachments: { ForEach(texts, id: \.self) { text in Attachment(id: text) { Text(text) .padding() .glassBackgroundEffect() } } } .toolbar { ToolbarItem { Button("Add") { //texts.append(String(UUID().uuidString.prefix(6))) let m = ModelEntity(mesh: .generateSphere(radius: 0.1), materials: [SimpleMaterial(color: .white, isMetallic: false)]) m.position.x = Float.random(in: -0.2...0.2) entities.append(m) } } ToolbarItem { Button("Remove") { //texts.remove(at: Int.random(in: 0..<texts.count)) entities.removeLast() } } } } } About the first code snippet, when I remove an element from the texts, why content can automatically remove the corresponding entity? And about the second code snippet, content do not automatically remove the corresponding entity. I am very curious.

This modifier in visionOS 2.5 works perfectly with LazyVgrid inside a Stack in ScrollView: .hoverEffect { effect, isActive, _ in effect.scaleEffect(isActive ? 1.1 : 1.0) But the grid does not scroll in visionOS 26 beta 1 unless the scaleEffect is commented out. FB17941468

I found some snapshot API in developer documents, like blows: RealityKit / Views and attachments / ARView / /snapshot(saveToHDR:completion:) SceneKit / SCNView / snapshot() Is there a similar API in visionOS？and if not, how can I implement snapshot for realityview and usdz?

Since using Quick Look exits you from both your app and Immersive Space. Is there a way to view immersive images within Immersive Space?

Are there any changes to RotationSystem: System and RotationComponent: Component that I should be aware of to see if I need to update my use in my visionOS app?

In Reality Composer, it is possible to create child components and manipulate them within the hierarchy of a ModelEntity. Is there a way to create child components in other 3D modeling programs, such as Blender?

Hello, I've pre-ordered the Logitech Muse with hopes of developing with it, but have yet to find any documentation relating to the capabilities it will have/any APIs that will be available to take advantage of the Muse. Is anyone aware of what might become available? Thank you in advance.

Do you retain a reference to your content (RealityViewContent) events? For example, the Manipulation Events docs from Apple use _ to discard the result. In theory the event should keep working while the content is alive. _ = content.subscribe(to: ManipulationEvents.WillBegin.self) { event in event.entity.components[ModelComponent.self]?.materials[0] = SimpleMaterial(color: .blue, isMetallic: false) } _ = content.subscribe(to: ManipulationEvents.WillEnd.self) { event in event.entity.components[ModelComponent.self]?.materials[0] = SimpleMaterial(color: .red, isMetallic: false) } We could store these events in state. I've seen this in a few samples and apps. @State var beginSubscription: EventSubscription? ... beginSubscription = content.subscribe(to: ManipulationEvents.WillBegin.self) { event in event.entity.components[ModelComponent.self]?.materials[0] = SimpleMaterial(color: .blue, isMetallic: false) } The main advantage I see is that we can be more explicit about when we remove the event. Are there other reasons to keep a reference to these events?

I am encountering an issue while using the multiview video demo provided at this link "https://developer.apple.com/documentation/avkit/creating-a-multiview-video-playback-experience-in-visionos/". Specifically, when running on versions of visionOS prior to 2.2, navigating back results in a blank screen. Has anyone else experienced this problem and found a solution? Any advice or workaround would be greatly appreciated.

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.

Copy of Feedback: FB15969432 Improve window management with immersive spaces. It is hard to manage windows from code when entering immersive space. Look for instance at the sample: https://developer.apple.com/documentation/visionos/displaying-a-3d-environment-through-a-portal The window displayed before entering the virtual space stays there once the virtual space is entered : this window is too big but can't be resized by the program. One could say this big window could be closed and a smaller window opened by the program with the "exit" button, but then this small window should be closed and the main window reopened when leaving te immersive space. In the immersive space closing the "Exit" window with the X does not allow to leave the immersive space. If the crown button is then used we go back to the Vision Pro main menu. If the app is chosen again we can see that it wasn't closed : the "Exit" window is now displayed but we are not in the immersive space! Don't say "this is just a sample app", because all developers face those issues. Please try to find the right solutions with your team to enhance this sample and share the right way to solve those issues. You could find that the specifications need to be enhanced. You can also see that there is no way to exit a program from a program even if this is something that could be useful for some apps (you end a SharePlay game for instance) Thank you very much for your time and consideration.

I have discovered that RemoteImmersiveSpace is limited to utilizing the structure of the CompositorContent protocol, precluding direct invocation of RealityView. Consequently, I am interested in understanding the appropriate method for integrating CompositorContent within RemoteImmersiveSpace. Thanks.

Hi, since iOS 18 UnlitMaterial and ShaderGraphMaterial have the option to disable tone mapping, e.g via https://developer.apple.com/documentation/realitykit/unlitmaterial/init(applypostprocesstonemap:) Is it possible to do the same for CustomMaterial? I tried initializing a CustomMaterial based on an UnlitMaterial where tone mapping is disabled, like so: let unlitMat = UnlitMaterial(applyPostProcessToneMap: false) let customMaterial = try CustomMaterial( from: unlitMat, surfaceShader: surfaceShader, geometryModifier: geometryModifier ) but that does not seem to work. The colors of my texture still look altered in comparison to a plain UnlitMaterial or a ShaderGraphMaterial where its disabled. Any hints? Thank you!

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

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)

Im just trying to setup some kind of visual on my iPad for testing and play purposes... I tried adding iPad to both APPLE Visual APPS. I get this error for both Building for 'iphoneos', but '12.0' must be >= '18.0'

I am trying to run widgets on visionOS 26. Specifically I am trying to pin them to the simulator room's walls, however I am unable to do so. Is this a limitation with the visionOS simulator right now, or am I missing a trick here?

Hello, In my project, I have attached a ManipulationComponent to Entity A and as expected, I'm able interact with it using the built-in gestures. I have another Entity B which is a child of A that I would like to interact with as well, so I attempted to add a ManipulationComponent to B. However, no gestures seem to be registered on B; I can still interact with A but B cannot be interacted with despite having ManipulationComponents on both entities. So I'm wondering if I'm just doing something wrong, if this is an issue with the ManipulationComponent, or if this is a limitation of the API. Attached is the code used to add the ManipulationComponent to an Entity and it was done on both A and B: let mc = ManipulationComponent() model.components.set(mc) var boxShape = ShapeResource.generateBox(width: 0.25, height: 0.05, depth: 0.25) boxShape = boxShape.offsetBy(translation: simd_float3(0, -0.05, -0.25)) ManipulationComponent.configureEntity(model, collisionShapes: [boxShape]) if var mc = model.components[ManipulationComponent.self] { mc.releaseBehavior = .stay mc.dynamics.inertia = .low model.components.set(mc) } I am using visionOS 26.0; let me know if there's any additional information needed.

The Section struct only publicly makes the center property available, but this is a SIMD3 that doesn't seem to line up with the rest of the model. All other objects have a 4x4 transform matrix that accurately gives each position and rotation. When inspecting a Section in the debugger, many more properties are visible such as polygon and transform. Why are these not visible? The transform in particular seems necessary to make any sort of use of the Sections.
