Hi, I'm working with CameraFrameProvider from Enterprise API. Is it always capped at 30fps, or is there something I can switch to get more? I assume it is capped at 30, so let me cram in additional question here :). If I'd get a developer strap and attach an external camera capable of doing >30fps, will I get the full stream, or some other limitation will kick in?

While using Screen Mirroring in developer mode within my immersive space, I noticed an alignment issue with the computer cursor (transparent circle). When I move it toward an attachment view, the cursor remains horizontal instead of aligning with the surface of the attachment view. It shows correctly on a 2D window only wrong on attachment view. Is this behavior a bug, or could it be caused by a missing or incorrect configuration on the attachment view? Want help, thanks.

I work on a game where I use timeline animations in Reality Composer Pro. The game runs in an immersive space, but can be paused where I then move the whole level root entity from the immersive space to another RealityView in a Window Group. When the player continues I do it exactly the other way around to move the level root from the window group back to my immersive space RealityView. And it seems like all animations get automatically stopped and restarted when the scene gets changed. The problem is, it does not resume where it stopped before, it completely starts again from where it stopped and therefore, has for example a wrong y offset as visible in the picture. For example in the picture, the yellow sphere loops the following animation: 0 to 100 100 to -100 -100 to 0 If I now pause the game (and basically switch scenes), the previous animation gets stopped and restarted at position y = 100. So now it loops: 100 to 200 200 to 0 0 to 100 I already tried all kind of setups - like: Setting the animations relative to root, parent, local Using behaviors (on Added to Scene, on Notification) And finally even by accessing the availableAnimations directly and saving the playback controller of the animation There I saw, if I manually trigger the following code before switching the scene, everything works as expected: Button("Reset") { animationPlaybackController.time = 0 animationPlaybackController.pause() animationPlaybackController.stop(blendOutDuration: 0.00001) } But if I use time = 0 with .stop() directly, the time = 0 seems to be ignored and I get the same behavior as before that it stops in a wrong y offset, hence my assumption that animations get stopped and invalidated once they change the scene. I tried to call the code manually on ImmersiveSpace.onDisappear, WindowGroup.onAppear and different kind of SceneEvents subscriptions, but unfortunately nothing worked. So am I doing something wrong in general or is there a way to fix this?

I have been experimenting with the Hello World sample app from https://developer.apple.com/documentation/visionos/world and I came across behavior that appears inconsistent with user-facing documentation describing the device controls at https://support.apple.com/en-gb/guide/apple-vision-pro/tan1e2a29e00/visionos I tried pressing simulator's "Home" button while "Objects in Orbit" immersive space was presented alongside with the main application window. According to user documentation, pressing Digital Crown should take the user directly to Home View. In my test a single press only dismissed the immersive space, I needed another press to "exit" the app and go to Home View. Is this behavior expected? I am assuming that "Home" button in the simulator behaves as if the user pressed Digital Crown on the device, I don't have access to the actual hardware.

How can I request access to Enterprise API for VisionPro with an individual developer account? I wanted it for learning and testing

I am developing a Unity application for the Apple Vision Pro using PolySpatial and RealityKit integration. The goal is to create a graspable object (for example, a handheld cube) that includes a secondary camera. When the user grabs and moves the object, the secondary camera should render its view to a RenderTexture, which is displayed on a quad attached to the object, simulating a live camera screen. In the Unity Editor, this setup works correctly. The RenderTexture updates in real time, and the quad displays the camera’s view as expected. However, when building and running the application on the Vision Pro, the quad only displays the clear background color of the secondary camera. No scene content appears. The graspable interaction itself works fine: the object can be grabbed and moved as intended. Steps I have taken: Created a new layer (CameraFeed) and assigned the relevant objects to it. Set the secondary camera’s culling mask to render only the CameraFeed layer. Assigned the RenderTexture as the camera’s target texture. Applied the RenderTexture to an Unlit/Texture material on a quad. Confirmed the camera is active and correctly positioned relative to the object. From my research, it appears that once objects are managed by RealityKit through PolySpatial (for example, made graspable), they are no longer rendered through Unity's normal camera pipeline. Only the main XR camera (managed by RealityKit) seems able to see these objects. Secondary Unity cameras cannot render RealityKit-synced content to a RenderTexture. If this is correct, it seems there is currently no way to implement a true live secondary camera feed showing graspable objects on Vision Pro using Unity PolySpatial. My questions are: Is there any official way to enable multiple camera rendering of RealityKit-managed objects through PolySpatial? Are there known workarounds to simulate a live camera feed that still allows objects to be grabbed? Has anyone found alternative design patterns or methods for this kind of interaction? Environment: Unity 6.0 , PolySpatial 2.2.4, Apple Vision OS XR 2.2.4 Any insight or suggestions would be greatly appreciated. Thank you.

Environment Xcode: 16.2 VisionOS SDK 2.4 Swift 6.1 Targets: Apple Vision Pro (immersive space) Frameworks: ARKit, RealityKit, SwiftUI What I’m Trying to Do I have a view-model class PlacementManager that holds two AR providers: private var worldTracking: WorldTrackingProvider private var planeDetection: PlaneDetectionProvider I want to dynamically replace these providers in a setEnvironment(_:) method (so I can save/clear a JSON scene and restart ARKit). What’s Happening If I declare them as : private let worldTracking = WorldTrackingProvider() private let planeDetection = PlaneDetectionProvider() I get compile-errors when I later do: self.worldTracking = newWorldTracking // Cannot assign to property: 'worldTracking' is a 'let' constant If I change them to un-initialized vars: private var worldTracking: WorldTrackingProvider private var planeDetection: PlaneDetectionProvider then in my init() I get: self used in property access 'worldTracking' before all stored properties are initialized Code snipet @Observable final class PlacementManager : ObservableObject { private var worldTracking: WorldTrackingProvider private var planeDetection: PlaneDetectionProvider // … other props … @MainActor init() { // error: self.worldTracking used before init… planeAnchorHandler = PlaneAnchorHandler(rootEntity: root) persistenceManager = PersistenceManager( worldTracking: worldTracking, rootEntity: root ) // … } @MainActor func setEnvironment(env: Environnement) async { let newWorldTracking = WorldTrackingProvider() let newPlaneDetection = PlaneDetectionProvider() try await appState!.arkitSession.run( [ newWorldTracking, newPlaneDetection ] ) self.worldTracking = newWorldTracking self.planeDetection = newPlaneDetection // … } } What I’ve Tried Giving them default values at declaration (= WorldTrackingProvider()) Initializing them at the top of init() before any use Passing the new providers into arkitSession.run(...) My Question What is the recommended Swift-style pattern to declare and reassign these ARKit provider properties so that: They’re fully initialized before use in init(), and I can swap them out later in setEnvironment(...) without compiler errors? Any pointers (or links to forum threads / docs) would be greatly appreciated!

Hi, after upgrading to 2.4.1 (from 1.0) my vision stucks on "Retrieving configuration" screen. Apple Store didn't support my case since it has been sold in USA and the product isn't still present in italian market. I don't have dev strap, how can I manage the issue? Thank you

Hi there, I was looking to add a particle emitter to my augmented reality app I'm developing using RealityKit. I'm targeting iOS. I noticed in the documentation for the ParticleEmitterComponent that it looks like iOS 18.0+ is supported, but when I try to use the ParticleEmitterComponent in my code in XCode, I get an error that it isn't found. Furthermore, this StackOverflow post seems to indicate that particle systems are not available for iOS. Would it be possible to get clarification on this?

I noticed that when I drag the menu window in an Immersive View, the entities behind it becomes semi-transparent, and the boundary between virtual and real-world objects is very pronounced. May I ask how does VisionOS implement this effect? Is there any API or technique I can use in my own code to enable the same semi-transparent overlay - even when I am not dragging the menu window?

Seeing this magical sand table, the unfolding and folding effects are similar to spreading out cards, which is very interesting. But I don't know how to achieve it. I want to see if there are any ways to achieve this effect and give some ideas. May I ask if this effect can be achieved under the existing API

How do you call the effect where the edges around the central image gradually become transparent? This effect is also seen when viewing immersive mode of spatial photos in Vision Pro. How can I achieve this effect using SwiftUI or ShaderGraph? I want to use this effect when displaying images in my app.

I'm starting my journey in developing an immersive app for VisionOS. I've been making steady progress, but I've encountered a specific challenge that I haven't been able to resolve. I created two ModelEntity objects — a sphere and a cube — and added a DragGesture to the cube. When I drag the cube over the sphere, the two collide correctly, and the collision is logged in the console. So far, everything works as expected. However, when I try to anchor the cube to my hand, the collision stops working. It's as if the cube loses its ability to detect collisions once it's anchored. Any guidance or clarification on this behavior would be greatly appreciated. //  ImmersiveView.swift //  estudos_vision // //  Created by Lailan Rogerio Rodrigues Matos on 15/05/25. // import SwiftUI import RealityKit import RealityKitContent struct ImmersiveView: View { @Environment(AppModel.self) var appModel @State private var session: SpatialTrackingSession? @State private var box = ModelEntity() @State private var subs: [EventSubscription] = [] @State private var ballEntity: Entity? var body: some View { RealityView { content in // Load initial content from the RealityKit scene. if let immersiveContentEntity = try? await Entity(named: "Immersive", in: realityKitContentBundle) { content.add(immersiveContentEntity) } // Create and run a spatial tracking session. let session = SpatialTrackingSession() let configuration = SpatialTrackingSession.Configuration(tracking: [.hand]) _ = await session.run(configuration) self.session = session // Create a red box. let boxMesh = MeshResource.generateBox(size: 0.2) let material = SimpleMaterial(color: .red, isMetallic: false) box = ModelEntity(mesh: boxMesh, materials: [material]) box.position.y += 0.15 // Position the box slightly above the origin. // Configure the box for user interaction and physics. box.components.set(InputTargetComponent(allowedInputTypes: .indirect)) // Make it interactive. box.generateCollisionShapes(recursive: false) // Generate collision shapes for physics. box.components.set(PhysicsBodyComponent( // Add physics behavior. massProperties: .default, material: .default, mode: .kinematic // Use kinematic mode so it can be moved by user interaction. )) box.components.set(GroundingShadowComponent(castsShadow: true)) // Add a shadow. //content.add(box) //commented out to add to hand anchor // Create a left hand anchor and add the box as a child. let handAnchor = AnchorEntity(.hand(.left, location: .palm), trackingMode: .continuous) handAnchor.addChild(box) content.add(handAnchor) // Add the hand anchor to the scene. // Create a sphere. let ball = ModelEntity(mesh: .generateSphere(radius: 0.15)) ball.position = [0.0, 1.5, -1.0] // Initial position of the ball. ball.generateCollisionShapes(recursive: false) // Add collision. ball.name = "Sphere" content.add(ball) ballEntity = ball // Subscribe to collision events between the box and other entities. let event = content.subscribe(to: CollisionEvents.Began.self, on: box) { ce in print("Collision between \(ce.entityA.name) and \(ce.entityB.name) occurred") //ce.entityA.removeFromParent() // removes the colliding object //ce.entityB.removeFromParent() } Task { subs.append(event) } } // Add a drag gesture to the box, allowing the user to move it. .gesture( DragGesture() .targetedToEntity(box) // Target the drag gesture to the box. .onChanged({ value in // Update the position of the box based on the drag gesture. box.position = value.convert(value.location3D, from: .local, to: box.parent!) }) ) } } #Preview(immersionStyle: .full) { ImmersiveView() .environment(AppModel()) }

Hi guys, In visionOS, when using a ZStack decorated with .glassBackgroundEffect(), you can see the 3D glass background from the front, but when viewed from the side, the view appears to have no thickness. However, I noticed that in an app built by Apple, when viewing a glass background view from the side, it appears to have thickness. I tried adding .frame(depth:) to a glass background view, but it appears as two separate layers spaced by the depth value. My question is: Is there a view modifier that adds visual thickness to a glass background view, as shown in the picture? Or, if not, how should I write a custom view modifier to achieve this effect? Thanks!

According to the official documentation, the .blur(radius:) modifier could apply gaussian blur to a realityview. However, when applied directly to a RealityView, nothing inside it (neither 2D attachments nor 3D entities) appears to be blurred. Here’s the test code: struct ContentView: View { var body: some View { VStack(spacing: 20) { Text("Above the RealityView") .font(.title) RealityView { content, attachments in if let text = attachments.entity(for: "2dView") { text.position.y = 0.1 content.add(text) } let box = ModelEntity( mesh: .generateBox(size: 0.1), materials: [SimpleMaterial(color: .red, isMetallic: true)] ) content.add(box) } attachments: { Attachment(id: "2dView") { Text("Above the Box") .font(.title) } } .frame(width: 300, height: 300) .border(.blue) .blur(radius: 99) // Has no visual effect Text("Below the RealityView") .font(.subheadline) } .padding() } } My question: How can I make .blur(radius:) visually affect the content rendered in a RealityView? Can you provide a working example that .blur() to visually affect any part of a RealityView? Thanks!

I have an entity that was created using Mixamo, and it has an animation. after the animation completes the mesh of the robot is not where the entity is positioned. I want to do something like when the animation finishes, I set the root entity's transform to the mesh's transform. There are no transformations applied to any of the children of this root of the model, which means that the transformations are applied to the skeleton due the the playing of animations. Is there a way where I can apply the final position of the root of the skeleton to the root entity to make sure to position the entity where the animation has ended just before the next animation plays?

Hello, I'm developing a visionOS application for Apple Vision Pro that aims to scan unknown physical objects, capture their 3D data (such as meshes or point clouds), and export them as 3D models. Ideally, I'd also like to visualize these reconstructions in real-time within the headset. This functionality is similar to what's available in Reality Composer on iPad and iPhone, but I'm seeking to implement it natively on Vision Pro. I've reviewed the visionOS documentation but haven't found clear guidance on accessing LiDAR depth data or performing scene reconstruction. Specifically, I'm interested in: 1.Accessing LiDAR or depth data from Vision Pro's sensors. 2.Utilizing ARKit's scene reconstruction capabilities on visionOS. 3.Exporting captured 3D data as models (e.g., USDZ or OBJ formats). Are there APIs or frameworks in visionOS that support these features?

I want to display a huge image in RealityView in 3d space on Vision Pro. of course instead of one giant file I'm using a lot of big images. to achieve this, I'm generating multiple planes exactly beside each others and put each image on them. although the planes are exactly beside each others but there is still a white gap between them.(image below) **Does anybody know how to fix this issue? **

I want to implement the functions in this video, how should I set the window
