Hello, I am trying to develop an app that broadcasts what the user sees via Apple Vision Pro. I am a graduate student studying at the university. And I have two problems, If I want to use passthrough in screen capture (in VisionOS), do I have to join Apple Developer Enterprise Program to get Enterprise API? and Can I buy Apple Developer Enterprise Program (Enterprise API) with my university account? Have any of you been able to do this? Thank you

Hi I have a monitoring app, that will take input video from uvc and process it using Metal, and eventually get a MTLTexture. The problem I'm facing is I have to convert MTLTexture to CGImage then call TextureResource.replace, which is super slow. Metal processing speed is same as input frame rate(50pfs), but MTLTexture -> CGImage -> TextureResource only got 7fps... Is there any way I can make it faster?

Hello Community, I'm encountering an issue with the latest iOS 17 update, specifically related to RoomPlan version-2. In iOS 16, when using RoomPlan version-1, we were able to display stairs in our app. However, after upgrading to iOS 17 and implementing RoomPlan version-2, the stairs are no longer visible. Despite thorough investigation, I couldn't find any option within the code to show or hide stairs, or any other objects for that matter. It seems like a specific issue with the update rather than a coding error on our part. Has anyone else encountered a similar problem? If so, I would greatly appreciate any insights or solutions you might have. It's crucial for our app functionality to have stairs displayed accurately, and we're currently at a loss on how to address this issue. Thank you in advance for any assistance you can provide. Best regards

是对原本VisionPro每个App的内存限制做了扩展嘛？放宽了内存限制么？

Hi Apple Team, We noticed the following exciting changelog in the latest macOS 26 beta: A new algorithm significantly improves PhotogrammetrySession reconstruction quality of low-texture objects not captured with the ObjectCaptureSession front end. It will be downloaded and cached once in the background when the PhotogrammetrySession is used at runtime. If network isn’t available at that time, the old low quality model will be used until the new one can be downloaded. There is no code change needed to get this improved model. (145220451) However after trying this on the latest beta and running some tests we do not see any differences on objects with low textures such as single coloured surfaces. Is there anything we are missing? the machine is definitely connected to the internet but we have no way of knowing from the logs if the new model is being used? thanks

Since updating to iOS 26.0 (and confirmed on 26.1), ARBodyTrackingConfiguration no longer detects a valid ARBodyAnchor on devices with LiDAR (e.g., iPhone 15 Pro, iPhone 17 Pro Max). This issue reproduces in custom projects and Apple’s official sample “Capturing Body Motion in 3D”. The AR session runs normally, but the delegate call: func session(_ session: ARSession, didUpdate anchors: [ARAnchor]) never yields an ARBodyAnchor with valid joint transforms. All joints return nil when calling: body.skeleton.modelTransform(for: jointName) resulting in 0 valid joints per frame. Environment • Device: iPhone 17 Pro Max (LiDAR) • iOS: 26.0 / 26.1 • Xcode: 16.0 (stable) • Framework: ARKit + RealityKit • Configuration used: config.worldAlignment = .gravityAndHeading config.isAutoFocusEnabled = true config.environmentTexturing = .none session.run(config) Also tested: with and without frameSemantics = .bodyDetection Expected Behavior ARBodyAnchor should be detected and body.skeleton should contain ~89 valid joints with continuous updates.

The WWDC25 video and notes titled “Learn About Apple Immersive Video Technologies” introduced the Apple Spatial Audio Format (ASAF) and codec (APAC). However, despite references throughout on using immersive video, there is scant information on ASAF/APAC (including no code examples and no framework references), and I’ve found no documentation in Apple’s APIs/Frameworks about its implementation and use months on. I want to leverage ambisonic audio in my app. I don’t want to write a custom AU if APAC will be opened up to developers. If you read the notes below along with the iPhone 17 advertising (“Video is captured with Spatial Audio for immersive listening”), it sounds like this is very much a live feature in iOS26. Anyone know the state of play? I’m across how the PHASE engine works, which is unrelated to what I’m asking about here. Original quote from video referenced above: “ASAF enables truly externalized audio experiences by ensuring acoustic cues are used to render the audio. It’s composed of new metadata coupled with linear PCM, and a powerful new spatial renderer that’s built into Apple platforms. It produces high resolution Spatial Audio through numerous point sources and high resolution sound scenes, or higher order ambisonics.” ”ASAF is carried inside of broadcast Wave files with linear PCM signals and metadata. You typically use ASAF in production, and to stream ASAF audio, you will need to encode that audio as an mp4 APAC file.” ”APAC efficiently distributes ASAF, and APAC is required for any Apple immersive video experience. APAC playback is available on all Apple platforms except watchOS, and supports Channels, Objects, Higher Order Ambisonics, Dialogue, Binaural audio, interactive elements, as well as provisioning for extendable metadata.”

Basically, take just the Xcode 26 AR App template, where we put the ContentView as the detail end of a NavigationStack. Opening app, the app uses < 20MB of memory. Tapping on Open AR the memory usage goes up to ~700MB for the AR Scene. Tapping back, the memory stays up at ~700MB. Checking with Debug memory graph I can still see all the RealityKit classes in the memory, like ARView, ARRenderView, ARSessionManager. Here's the sample app to illustrate the issue. PS: To keep memory pressure on the system low, there should be a way of freeing all the memory the AR uses for apps that only occasionally show AR scenes.

Hi all, I'm working on an ARKit-based iOS app where I need to accurately determine the direction the device is facing to localize objects in the real world. I'm using: let config = ARWorldTrackingConfiguration() config.worldAlignment = .gravityAndHeading Thus, I would expect the world alignment to behave as given in the gravityAndHeading page. The AR session is started after verifying that CLLocationManager.headingAccuracy <= 20, and the compass appears to be calibrated. However, I'm seeing a major inconsistency: When the rear camera is physically pointed toward true North, I would expect: cameraTransform.columns.2.z ≈ -1 // (i.e. ARKit's -Z pointing North) But instead, I'm consistently seeing: cameraTransform.columns.2.z ≈ +0.97 // Implies camera is facing South Meanwhile, the translation vector behaves as expected: As I physically move North, cameraTransform.columns.3.z becomes more negative, matching the world’s +Z = South assumption. For example, let's say I have the device in landscapeRight (or landscapeLeft for UIDeviceOrientation). Let's say the device rear camera is pointing towards True North, and I start moving towards True North. I get something like this: Camera Transform = simd_float4x4( [ [0.98446155, -0.030119859, 0.172998, 0.0], [0.023979114, 0.9990097, 0.037477385, 0.0], [-0.17395553, -0.032746706, 0.98420894, 0.0], [0.024039675, -0.037087332, -0.22780673, 0.99999994] ]) As you can see, the cameraTransform.columns.2.z is positive despite the rear camera pointing towards True North, while cameraTransform.columns.3.z is correctly positive as the device is moving towards True North. So here is my question: Why is cameraTransform.columns.2.z positive when the rear camera is physically facing North? Any clarity would be deeply appreciated. I've read the documentation and tested with different heading accuracies and AR session resets, but I keep running into this orientation mismatch. Thanks in advance!

I've got an Immersive scene that I want to be able to bring additional users into via SharePlay where each user would be able to see (and hopefully interact) with the Immersive scene. How does one implement that?

I am looking for a material that functions in the same way that Occlusion Material does, except that it only partially occludes whatever is behind it. One way that I have thought of doing this was to change the opacity of the entity that was covered in Occlusion Material, however this did not change anything. Please let me know if this is possible.

Spatial widget is a new feature of visionos 26. I notice The system’s Photo app can add a Spatial Image in the widget. I wonder if third apps can use spatial image or any 3D content in it's widget? I try to use RealityView in widget and it run with a crash. So does spatial Image in widget only supported by the system Photo app, and not available to developers now?

I am trying to get the new PresentationComponent working in VisionOS26 as seen in this WWDC video: https://developer.apple.com/videos/play/wwdc2025/274/?time=962 (18:29 minutes into video) Here is some other example code but it doesn't work either: https://stepinto.vision/devlogs/project-graveyard-devlog-002/ My simple Text view (that I am adding as a PresentationComponent) does not appear in my RealityView even though the entity is found. Here is a simple example built from an Xcode immersive view default project: struct ImmersiveView: View { @Environment(AppModel.self) var appModel var body: some View { RealityView { content in // Add the initial RealityKit content if let immersiveContentEntity = try? await Entity(named: "Immersive", in: realityKitContentBundle) { content.add(immersiveContentEntity) if let materializedImmersiveContentEntity = try? await Entity(named: "Test", in: realityKitContentBundle) { content.add(materializedImmersiveContentEntity) var presentation = PresentationComponent( configuration: .popover(arrowEdge: .bottom), content: Text("Hello, World!") .foregroundColor(.red) ) presentation.isPresented = true materializedImmersiveContentEntity.components.set(presentation) } } } } } Here is the Apple reference: https://developer.apple.com/documentation/realitykit/presentationcomponent

I am trying to create an object in immersive space that is partially transparent (~50% opacity). I have implemented this in a few different ways including creating a model entity and setting its opacity component to 0.5, and creating a custom material with blending set to a transparent opacity of 0.5. These both work partially, as they behaved as intended for many cases, but seemingly randomly would act like occlusion material and block any other immersive content behind them, showing the real world instead. Some notes: I am using RealityKit to render the semi-transparent object and an opaque object that is behind the semi-transparent object. I am using VisionOS 2.1, and am updating the location of the semi-transparent object often. Both objects are ModelEntities. I would appreciate any guidance on how to implement this. Please let me know if there are any other questions.

Hello again! So, I am trying my best to figure out how to get a simple, fully Immersive scene that is navigable via the PS5 controller to work on Vision Pro. I am even using ChatGPT (both externally AND in Xcode when it makes fix recommendations) however, I seem to be moving around in circles, having to constantly send error messages back to ChatGPT, then try the new "confirmed to work" fixed code, only to have more errors. I also have explicitly let the AI know that I'm using all the current betas, only to learn there has been lots of stuff deprecated (of course!). This is my initial query to ChatGPT: "How can I create a fully immersive VR experience for Apple Vision Pro, using a PS5 game controller to navigate the user via first person view through a 3d scene?" And then down the rabbit hole the past few days. Seriously, I thought AI was supposed to be helpful! LOL Per Xcode logs, I'm seeing thumbstick movement, but simply cannot get the camera to move. Is this even possible?! Is it a camera defined in Reality Composer Pro? Or, does it need to be defined outside. I'm trying to follow along with the AI, but it seems to go back and forth with different solutions. Here is the latest it's spitting out: __ Thanks for this super clear log — and you’re absolutely right: the gamepad input is working, CameraRoot is moving as expected… but your actual camera view is not changing. This strongly suggests the issue is that RealityKit is not using your custom camera (PerspectiveCameraComponent) for rendering the view. ⸻ 🔍 What’s happening Even though CameraRoot is moving (with correct logs), RealityKit will default to its own internal camera unless: 1. You explicitly assign your camera entity to be the one used, or 2. Your camera is the only one and RealityKit picks it up automatically. But in visionOS 2.0 / Xcode 26, there seems to be a bug or behavior change where RealityKit no longer auto-uses your custom PerspectiveCameraComponent in RealityView unless it’s: • properly set with content.camera, or • part of a .usda/Reality Composer camera hierarchy that’s already active. Unfortunately: 🟥 RealityView.camera = .entity(cameraRoot) ❌ Is no longer allowed (we confirmed this breaks with a type error) ⸻ ✅ The Reliable Workaround: Attach your camera to the Immersive scene itself Since we’re loading a .usda scene (Reality Composer Pro), here’s the most reliable path forward: ✔️ Option A: Embed your camera into the Reality Composer Pro scene 1. Open your Reality Composer Pro scene 2. Add a Camera entity directly in your Immersive.usda scene 3. Name it something like "PlayerCamera" 4. Position it at [0, 1.6, 0] 5. Leave it selected as the default camera Then in your Swift code: • Find the camera entity with .findEntity(named:) • Move that entity instead of creating a new one. ⸻ ✔️ Option B: Force RealityKit to use your custom camera (via transform parenting) Since direct camera assignment is unavailable, we can use a trick: Move the whole RealityView scene via a parent entity with a camera. But let’s go with Option A, since you’ve already got a Reality Composer Pro scene. __ Can any developer over there can make a suggestion on how to move forward? I JUST want to create a sandbox template so I can start exploring 3d scenes created in Maya and sent over to headset. I'll deal with animation next, but come on, why is this so difficult to get working? I'm not a programmer, but have been trying to wrap my head around Xcode and SwiftUI. This needs to be much simpler. Or, you need to provide us creatives with better sample templates and non programmer speak on how to set this up properly. Ideally, you HIRE us 3d professionals to work side by side with the programmers to help make these tools useable - especially Reality Composer Pro. Seriously, I am making a concerted effort to use the native tools, even though I would love to be porting Unreal Engine scenes over. If anyone can help point me in the right direction, coming from a 3D Creator/Animator/Modeler perspective, I, and my fellow peers in the XR/AR/VR community would greatly appreciate it. Thank you.

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?

Hello, I'm working with the new PortalComponent introduced in visionOS 2.0, and I've encountered some issues when transitioning entities between virtual and real-world spaces using crossingMode. Specifically: Lighting inconsistency: When CG content (ModelEntities with PhysicallyBasedMaterial) crosses the portal from virtual space into the real environment, the way light reflects on the objects changes noticeably. This causes a jarring visual effect, as the same material appears differently depending on the space it's in. Unnatural transition visuals: During the transition, the CG models often appear to "emerge from the wall," especially when crossing from virtual to real. This ruins the immersive illusion and feels visually unnatural. IBL adjustment attempts: I’ve tried adding an ImageBasedLightComponent to the world entity, and while it slightly improves the lighting consistency, the issue still remains to a noticeable degree. My goal is to create a seamless visual experience when CG entities cross between spaces, without sudden lighting shifts or immersion-breaking geometry reveals. Has anyone else experienced similar issues? Is there a recommended setup or workaround to better control lighting and visual fidelity when using crossingMode with portals in visionOS 2.0? Any guidance would be greatly appreciated. Thank you!

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()) }

Previously I had developed software using SMI eye trackers, both screen mounted and their mobile glasses, for unique therapeutic and physiology applications. Sadly, after SMI was bought by Apple, their hardware and software have been taken off the market and now it is very difficult to get secondhand-market systems. The Apple Vision Pro integrates the SMI hardware. While I can use ARKit to get gaze position, I do not see a way to access information that was previously made accessible on the SMI hardware, particularly: dwell time and pupil diameter information. I am hopeful (or asking) to see that if a user has a properly set up Optic ID and would opt-in if, either on the present or a future version of visionOS, it might be possible to get access to the data streams for dwell times and pupil diameter. Pupil diameter is particularly important as it is a very good physiological measure of how much stress a person is encountering, which is critical to some of the therapeutic applications that formerly we used SMI hardware. Any ideas, or, if this is not possible, proposing this to the visionOS team would be appreciated!
