I have a VideoMaterial inside a RealityView and want to attach this to a DockingRegion inside an immersive environment. It appears that adding the VideoMaterial entity as a child of the docking region somewhat works, but there are no lighting effects (specular, diffuse) from the playing video. So essentially, how can you add a VideoMaterial to a DockingRegion and achieve the same reflections/behavior as using AVPlayerViewController. The latter is not an option as I need custom controls.

I am trying to create reflections and lighting in a fully virtual scene, and the way the documentation is written, the VirtualEnvironmentProbeComponent would be key. I cannot seem to get it to work, however. Has anyone got this figured out?

Hi, I’m working on a portfolio project for Vision Pro these days. I have two projects and each of projects are made with Unity and made with Xcode(using ARKit and RealityKit tracking feature). Is it able to combine these two projects in an app? For example, using the buttons made with SwiftUI in a Reality Composer Pro, jumping to a scene in Unity, and back from a scene in Unity to a scene in Reality Composer Pro in an app.

I am attempting to use the Barcode Detection enterprise API. I have the necessary entitlements and license file. I'm following the sample code online, and whenever I attempt to run the barcode detection using arKitSession.run I get the following error message: ar_barcode_detection_provider_t <0x300d82130>: Failed to run provider with transient error code: 1 It obviously isn't running the barcode detection, even though it's running in an immersive space in mixed mode. Any idea what might be going on?

I'm seeking detailed information about the rotation matrix of the iPhone's front-facing (selfie) camera when using ARKit. Specifically, I need to understand: The exact rotation matrix applied to the front-facing camera's output in ARKit. Whether this matrix is consistent across all iPhone models or if there are variations. If there are any transformations applied to align the camera's coordinate system with the device's orientation, particularly in portrait mode. How this rotation matrix relates to the transform property of `ARFrame.camera

I'm exploring face tracking and experimenting with ARKit's ARSCNFaceGeometry face mesh. I'm running a minimal demo application on the latest iPad Pro M4 11-inch, and I've provided the code below. I've heard that Apple still offers some of the best face tracking technology on consumer devices, largely because they are one of the few that combine depth and image data. Both a colleague and I tested the demo, and while it works as well or better than some other solutions we tried, we weren’t particularly impressed compared to Google’s MediaPipe or Nvidia’s Maxine, both of which rely solely on image data without depth. In our case, the ARKit face mesh doesn’t always align perfectly with the chin, and as the face rotates, in some areas vertices shift by up to a centimeter from their original position. This led us to question whether our demo app was using the TrueDepth sensor at all. To test this, we used a piece of cardboard with a small hole punched in it and taped it over the sensor array, leaving only the camera exposed. On the iOS lock screen, this prevents FaceID from working, but we still get a clear image from the camera. With the TrueDepth sensor blocked, the face mesh tracking in our app still functioned, but honestly, we couldn’t detect a significant difference in tracking performance with or without the TrueDepth sensor obscured. Could we be setting up the face tracking configuration incorrectly? Or has face tracking in newer versions of iOS become less dependent on the TrueDepth sensor? The controller: import SwiftUI import ARKit struct FaceTrackingView1: UIViewControllerRepresentable { func makeUIViewController(context: Context) -> FaceTrackingViewController1 { return FaceTrackingViewController1() } func updateUIViewController(_ uiViewController: FaceTrackingViewController1, context: Context) { } } class FaceTrackingViewController1: UIViewController, ARSCNViewDelegate, ARSessionDelegate { var sceneView: ARSCNView! override func viewDidLoad() { super.viewDidLoad() sceneView = ARSCNView(frame: view.bounds) sceneView.delegate = self sceneView.automaticallyUpdatesLighting = true view.addSubview(sceneView) let config = ARFaceTrackingConfiguration() sceneView.session.run(config) } override func viewWillDisappear(_ animated: Bool) { super.viewWillDisappear(animated) sceneView.session.pause() } func renderer(_ renderer: SCNSceneRenderer, nodeFor anchor: ARAnchor) -> SCNNode? { guard anchor is ARFaceAnchor else { return nil } let faceGeometry = ARSCNFaceGeometry(device: sceneView.device!)! let faceNode = SCNNode(geometry: faceGeometry) faceNode.geometry?.firstMaterial?.fillMode = .lines // Makes it a wireframe mesh return faceNode } func renderer(_ renderer: SCNSceneRenderer, didUpdate node: SCNNode, for anchor: ARAnchor) { guard let faceAnchor = anchor as? ARFaceAnchor, let faceGeometry = node.geometry as? ARSCNFaceGeometry else { return } faceGeometry.update(from: faceAnchor.geometry) } } The view: import SwiftUI struct ContentView: View { @State private var isFaceTrackingActive = false var body: some View { VStack { Text("Face mesh tracking demo") .font(.title) .padding() Button(action: { isFaceTrackingActive.toggle() }) { Text("Start Face Tracking") .font(.title2) .padding() .background(Color.blue) .foregroundColor(.white) .cornerRadius(10) } .fullScreenCover(isPresented: $isFaceTrackingActive) { FaceTrackingView1() } } .padding() } } #Preview { ContentView() }

Hi everyone, I'm looking for some guidance on how to create an .arobject file. Is there a way to generate it from a 3D model (like a .objcap or .usdz or .fbx/.obj file)? Or can it only be generated by scanning a real-world object using the ARKitScanner project? Any advice or resources on this would be greatly appreciated! I've only found this project for scanning real-world objects. Thanks in advance!

Hi everyone, I’m working on an app for VisionOS that needs to recognize individual rooms in a hallway based on the person the room belongs to (using the name displayed on each office door). Is there any sample code or resource that can guide me in implementing this feature? Thanks in advance for your help!

Hello Apple Team, Is it possible to change the zoom factor, exposure, white balance and other settings, of an iOS ARKit session? I know how to do it using an AVCaptureSession, however, I can't figure out how to access the AVCaptureDeviceInput of the current AR session. Thanks PS: I'm using ARkit and RealityKit on iOS 17

I tested the new visionOS object tracking and it worked really well. I have created a reference object using Create ML and it really detected the object. My question is: does it work also with iOS and, if not right now, is it planned to work in mobile iOS in the future?

I have created two scenes, one immersive and one volumetric using Reality Composer Pro. In my test app I can view both and they render correctly. However, I would like to add entities programmatically. I am trying this; var body: some View { RealityView { content in if let scene = try? await Entity(named: "Scene", in: realityKitContentBundle) { viewModel.rootEntity = scene content.add(scene) var anchorEntity = AnchorEntity(world: [0, 0, -0.5]) let sphere = MeshResource.generateSphere(radius: 2.0) let material = SimpleMaterial(color: .red, roughness: 0.5, isMetallic: true) let modelEntity = ModelEntity(mesh: sphere, materials: [material]) anchorEntity.addChild(modelEntity) content.add(anchorEntity) } } } However, the sphere does not appear in the volume. I also tried it in the immersive space and it does not appear there either. What am I missing?

With Xcode16 and VIsionOS SDK 2.0, result of consecutive ar_anchor_get_timestamp may differ many seconds. Is there any way to detect the timestamp jumping?

In the visionOS App, I want to detect whether the user is in the room. My idea is as follows: Check whether there are walls around the user May I ask how to do it? Thanks！

I have created a portal and attached it to a wall using the AnchorEntity. However, I am seeking guidance on how to determine the size of the wall so that the portal can fully occupy it. Initially, I attempted to locate relevant information within the demo code, but I encountered difficulties in comprehending certain sections. I would appreciate it if someone could provide a step-by-step explanation or a reference to the appropriate code. Thank you for your assistance.

We are currently using Apple's Object capture module and wonder if it would be possible to collect the following data : Device information Current translation / rotation Focal length embedded to the image headers GPS localisation information. Information about the exposure time White balances and the color correction matrices We also have 2 additional questions : Is there an option to block close up accomodation of the camera ? Is there a way for the object capture module to take a video instead of a series of picture ?

After upgrading to Xcode 16 my app, which utilizes imported project files from my iPad's Reality Composer app, now has two issues that I have found so far. I am using an ARView as a UIViewRepresentable with SwiftUI. (Prior to upgading to Xcode 16 everything worked well.) First, there are now several duplicate rcp_export.usdz resources in the "Copy Bundle Resources" build phase section. Even though each file is in a separate folder with a unique UUID, it was causing a compile error saying there are duplicate files. I was able to open the RC project folder and delete the older rcp_project versions which now allows the app to compile. I mention it as it may or may not be related to the second issue. Second, Xcode isn't generating the project code for rcproject, so when I call the RCProject.loadSceneAsync function I am getting an error that says "Cannot find 'RCProject' in scope"

Hi guys I'm currently developing a game for the Vision Pro and i'm trying to figure out how the hand tracking works so I can make a superpower appear when the user looks at their hand and widens it. But im really struggling to wrap my head around the whole concept and how to implement it in my code. Is there anything out there (other than apple doc) or anyone who could help me shed some light on the whole idea and how I could actually usefully implement it? would be much appreciated Thanks

To set the stage: I made a prototype of an app for a company, the app is to be used internally right now. Prototype runs perfectly on iOS, so now I got VP to port the app to its final destination. The first thing I found out is that the image tracking on VP is useless for moving images (and that's the core of my app). Also distance at which image is lost seems to be way shorter on VP. Now I'm trying to figure out if it's possible to fix/work around it in any way and I'm wondering if Enterprise API would change anything. So: Is it possible to request Enterprise API access as a single person with basic Apple Developer subscription? I looked around the forum and only got more confused. Does QR code detection and tracking work any better than image detection, or anchor updates are the same? Does the increased "object detection" frequency affect in any way image/QR tracking, or is it (as name implies) only for object tracking? Would increasing the CPU/GPU headroom make any change to image/QR detection frequency? Is there something to disable to make anchor updates more frequent? I don't need complex models, shadows, physics, etc. Greetings Michal

I’m currently working on a project where I need to display a transparent GIF at a specific 3D point within an AR environment. I’ve tried various methods, including using RealityKit with UnlitMaterial and TextureResource, but the GIF still appears with a black background instead of being transparent. Does anyone have experience with displaying animated transparent GIFs on an AR plane or point? Any guidance on how to achieve true transparency for GIFs in ARKit or RealityKit would be appreciated.

When I first install and run the app, it requests authorization for hand tracking data. But then if I go to the settings and disable hand tracking from the app, it no longer requests. The output of requestAuthorization(for:) method just says [handTracking : denied] Any idea why the push request only shows up once then never again?
