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"

We would like to create an Immersive video and store the video file locally in Vision Pro for viewing. By Immersive video, I mean the video that is played at the end of the Vision Pro experience at the Apple Store (LeBron's dunk, Curry's 3-point shot, tightrope walk, etc.). It is unclear if a way is currently provided to view Immersive video locally. I can find some information about Spatial video on the Dev site, but I can't find any information about Immersive video. My understanding is: Spatial video: A video window appears in space and plays video with depth. Up to 4K side-by-side video can be converted to MV-HEVC format using Xcode and played back in the Photos app. Immersive video: 180VR video, but I’m not sure how it was created. Similar to Spatial video, I converted a side-by-side 180VR video to MV-HEVC format using Xcode, but it could not be played back in the Photos app as expected. Vision Pro's Photos app features an Immersive button during video playback, but this appears to be for zooming in on Spatial video to the full field of view, which seems different from Immersive video. The demo video provided by Apple is streamed from Apple TV, and there are no local files available. We are currently considering creating an app that displays different videos to each eye, but we prefer not to go this route due to licensing and distribution issues.

We tried out our Unity-based AR app for the very first time under iOS 18 and noticed an immediate, repeatable crash. When run in Xcode 16, we get this error message: Assert: /Library/Caches/com.apple.xbs/Sources/AppleCV3D/library/VIO/CAPI/src/SlamAnchor.cpp:37 : HasValidPose() Assert: /Library/Caches/com.apple.xbs/Sources/AppleCV3D/library/VIO/CAPI/src/SlamAnchor.cpp:37 : HasValidPose() That's a blocker to us. We're using Unity 2022.3.27f1.

Dear all, We are building an XR application demonstrating our research on open-vocabulary 3D instance segmentation for assistive technology. We intend on bringing it to visionOS using the new Enterprise APIs. Our method was trained on datasets resembling ScanNet which contain the following: localized (1) RGB camera frames (2) with Depth (3) and camera intrinsics (4) point cloud (5) I understand, we can query (1), (2), and (4) from the CameraFrameProvider. As for (3) and (4), it is unclear to me if/how we can obtain that data. In handheld ARKit, this example project demos how the depthMap can be used to simulate raw point clouds. However, this property doesn't seem to be available in visionOS. Is there some way for us to obtain depth data associated with camera frames? "Faking" depth data from the SceneReconstructionProvider-generated meshes is too coarse for our method. I hope I'm just missing some detail and there's some way to configure CameraFrameProvider to also deliver depth and/or point clouds. Thanks for any help or pointer in the right direction! ~ Alex

Hi everyone I am working on a small project that requires World Anchors so that I can persist my content through whenever the user chooses to leave/close the app. However I can't manage to make my Arkit session to run even though I think all the privacy permissions have been set and allowed correctly. Here is a sample code in an empty scene: // // WorldTrackingView.swift // SH_AVP_Demo // // Created by 李希 on 9/19/24. // import SwiftUI import RealityKit import RealityKitContent //import VisionKit import ARKit import Foundation import UIKit import simd struct WorldTrackingView_test: View { @State var myCube = Entity() @Environment(.scenePhase) var myScenePhase var body: some View { RealityView { content in //Load Scene if let Scene = try? await Entity.load(named: "WorldTrackingScene", in: realityKitContentBundle){ //Add scene to the view content.add(Scene) //Look for the cube entity if let cubeEntity = Scene.findEntity(named: "Cube"){ myCube = cubeEntity // Create collission for the cube myCube.generateCollisionShapes(recursive: true) // Allow inputs to interact myCube.components.set(InputTargetComponent(allowedInputTypes: .indirect)) // set some ground shadows myCube.components.set(GroundingShadowComponent(castsShadow: true)) } } } // Add drag gesture that targets any entity in the scene .gesture(DragGesture().targetedToAnyEntity() //Do something when the cube position changes .onChanged{ value in value.entity.position = value.convert(value.location3D, from: .local, to: value.entity.parent!) myCube = value.entity // Test and see if the Arkit runs with different data providers var session = ARKitSession() var worldData = WorldTrackingProvider() let planeData = PlaneDetectionProvider() let sceneData = SceneReconstructionProvider() do { Task{ try await session.run([worldData]) for await update in worldData.anchorUpdates { switch update.event { case .added, .updated: // Update the app's understanding of this world anchor. print("Anchor position updated.") case .removed: // Remove content related to this anchor. print("Anchor position now unknown.") } } } }catch{ print("session not running \(error.localizedDescription)") return } } //At the end of the gesture save anchor .onEnded{ value in } ) } } #Preview(immersionStyle: .mixed) { WorldTrackingView() } All is does is to generate a cube in an immersive view. The cube has collision and input components added to so that I can interact with it using a drag gesture. I decided to start an arkit session with a WorldTrackingProvider() but I keep getting the following error: ARPredictorRemoteService <0x117e0c620>: Service configured with error: Error Domain=com.apple.arkit.error Code=501 "(null)" Remote Service was invalidated: <ARPredictorRemoteService: 0x117e0c620>, will stop all data_providers.

UserInfo={NSDebugDescription=The connection to service with pid 81 named com.apple.arkit.service.prediction was invalidated from this process.} ARRemoteService: weak self released before invalidation If I switch it with a PlaneDetectionProvider() or a SceneReconstructionProvider() I get print statements in my terminal, but none if i replace it with a WorldTrackingProvider(). Any idea what could be causing this? Same code was working before a recent for xcode I believe.

I am using RealityView for an iOS program. Is it possible to turn off the camera passthrough, so only my virtual content is showing? I am looking to create VR experience. I have a work around where I turn off occlusion and then create a sphere around me (e.g., with a black texture), but in the pre-RealityView days, I think I used something like this: arView.environment.background = .color(.black) Is there something similar in RealityView for iOS? Here are some snippets of my current work around inside RealityView. First create the sphere to surround the user: // Create sphere let blackMaterial = UnlitMaterial(color: .black) let sphereMesh = MeshResource.generateSphere(radius: 100) let sphereModelComponent = ModelComponent(mesh: sphereMesh, materials: [blackMaterial]) let sphereEntity = Entity() sphereEntity.components.set(sphereModelComponent) sphereEntity.scale *= .init(x: -1, y: 1, z: 1) content.add(sphereEntity) Then turn off occlusion: // Turn off occlusion let configuration = SpatialTrackingSession.Configuration( tracking: [], sceneUnderstanding: [], camera: .back) let session = SpatialTrackingSession() await session.run(configuration)

Hello, I want to know who is in charge for the integration of a new ARKit update for the Unreal Engine. We want to use the AR function from the AVP with Ubreal, but the ARKit version is too old.

Hi, We are a team of student working on a project featuring the Vision Pro, and we'd simply like to know if a 3rd party app can access the video stream of the front cameras? From our tests, FaceTime for exemple, is able to screen share the entire stream that the user is seeing. (real world + app windows), but apps as Discord, are only able to share app windows, the real world is fully black. Is it a privacy security, or is it because 3rd parties app doesn't yet support the stream of the front cameras? To give some more context, we'd like to screenshot an area of the view (real world), with a pinch and drag gesture, and then access the screenshot to work on it. How would we be able to access the video stream? Thanks in advance for your help, MrCubic

Hello! I am working on some cool project reconstructions for a client. They design lobby sized installations with LED walls. I am being tasked with converting these over to AR at scale. I've got my first test in headset and it looks great! However, the desire to just walk around more than the 10' x 10' safe area zone totally takes one out of the immersive VR experience - which is pretty counter intuitive. Is there any way for us developers to by pass this hard limit, so that clients who are requesting more room-scale options can actually enjoy this in VR? Alternatively, is there a way to hook up a PS5 controller to a "player start" so I can navigate inside the VR volume? I'm really trying to embrace Reality Composer Pro, but it seems extremely limiting as I wait for Unreal Engine to get its act together. sigh. Thanks for any help or suggestions.

Hi, from the 2023 WWDC video on RoomPlan, they mention that it should be possible to integrate photo / video with RoomPlan: https://developer.apple.com/videos/play/wwdc2023/10192/ (at ~2:30) However, when I attempt to use AVFoundation and AVCaptureSession with RoomPlan, I get the simple error of "Cannot Record". So I'm not sure if there is something wrong with my setup/code, or if these two libraries are actually incompatible. Are there any kinds of guides for doing things like this? Am I going in the right direction or should I try a different approach? Happy to share code if necessary. Thanks

I’m developing a visionOS app using EnterpriseKit, and I need access to the main camera for QR code detection. I’m using the ARKit CameraFrameProvider and ARKitSession to capture frames, but I’m encountering this error when trying to start the camera stream: ar_camera_frame_provider_t: Failed to start camera stream with error: <ar_error_t Error Domain=com.apple.arkit Code=100 "App not authorized."> Context: VisionOS using EnterpriseKit for camera access and QR code scanning. My Info.plist includes necessary permissions like NSCameraUsageDescription and NSWorldSensingUsageDescription. I’ve added the com.apple.developer.arkit.main-camera-access.allow entitlement as per the official documentation here. My app is allowed camera access as shown in the logs (Authorization status: [cameraAccess: allowed]), but the camera stream still fails to start with the “App not authorized” error. I followed Apple’s WWDC 2024 sample code for accessing the main camera in visionOS from this session. Sample of My Code: import ARKit import Vision class QRCodeScanner: ObservableObject { private var arKitSession = ARKitSession() private var cameraFrameProvider = CameraFrameProvider() private var pixelBuffer: CVPixelBuffer? init() { Task { await requestCameraAccess() } } private func requestCameraAccess() async { await arKitSession.queryAuthorization(for: [.cameraAccess]) do { try await arKitSession.run([cameraFrameProvider]) } catch { print("Failed to start ARKit session: \(error)") return } let formats = CameraVideoFormat.supportedVideoFormats(for: .main, cameraPositions: [.left]) guard let cameraFrameUpdates = cameraFrameProvider.cameraFrameUpdates(for: formats[0]) else { return } Task { for await cameraFrame in cameraFrameUpdates { guard let mainCameraSample = cameraFrame.sample(for: .left) else { continue } self.pixelBuffer = mainCameraSample.pixelBuffer // QR Code detection code here } } } } Things I’ve Tried: Verified entitlements in both Info.plist and .entitlements files. I have added the com.apple.developer.arkit.main-camera-access.allow entitlement. Confirmed camera permissions in the privacy settings. Followed the official documentation and WWDC 2024 sample code. Checked my provisioning profile to ensure it supports ARKit camera access. Request: Has anyone encountered this “App not authorized” error when accessing the main camera via ARKit in visionOS using EnterpriseKit? Are there additional entitlements or provisioning profile configurations I might be missing? Any help would be greatly appreciated! I haven't seen any official examples using new API for main camera access and no open source examples either.

In RealityKit, I know that an HDR image is pre-calculated, and through the settings of the ImageBasedLight Component, a specified specular object can reflect the content of the HDR image. If a mirror object is originally very large, such as a large-area continuous glass door, after specifying an IBL image for these glass doors, the image reflected by the mirror will be obviously deformed when it moves in space. Because IBL is a picture of the surrounding environment at a point, while the glass door is a surface. Is there a truly real-time specular reflection calculation setup in RealityKit that can reflect the model on the opposite side of the glass door?

Hello everyone, I'm a Computer Science student. My supervisor has given me some topics for my final year project, and one of them involves using Vision Pro for facial recognition—specifically, identifying a designated face to display specific information. As a developer, my understanding of Vision Pro is quite limited. I've done some research online and found that Unity and Xcode are used as development tools. Traditionally, facial recognition is done using OpenCV. However, I've come across articles stating that Apple, due to security reasons, cannot implement facial recognition. I’d like to ask if that’s true. Also, with VisionOS 2 featuring object tracking and image tracking, could these methods potentially replace facial recognition?

In visionOS, I want to make a watch. After the actual production, the display of the hand makes it impossible to see the watch due to the virtual watch. How to set up the watch to give priority to display?

https://developer.apple.com/documentation/compositorservices/drawing_fully_immersive_content_using_metal I'm following this doc to use metal in vision os. I noticed that the tangent is being deprecated which is being used in the sample https://developer.apple.com/documentation/compositorservices/layerrenderer/drawable/view will the sample code be updated?

In iOS, to display a RealityView, you can assign a value to the content.camera property: content.camera = .virtual However, how can this be implemented in macOS and tvOS?

Hello, Would it be possible to use any of the available visionOS environments when I use an app that requires me to be in an immersive space? I'm developing an app where users can start the immersive space experience by pressing a button. In my case, it would be helpful if the user could still choose a visionOS environment using the Digital Crown, but currently, it seems to be unavailable after opening an immersive space. Thank you very much in advance!

I have no clue at all. Any suggestions are welcome. Thank you.

How to create fire effect in Reality Composer Pro? Should I use particle emitter?

Hi everyone, I want to add new joint in addition to joints that provided by ARKit. for example extract the position of wrist and elbow, then add new joint between them in the middle of arm. I can't find a good documentation that can explain ARKit very well. If there is another information that I can use, please share it with me. thanks.
