Please provide access to face tracking blendshapes on vision os
Apple, please provide access to face tracking blend shapes on vision os, just like you do on iOS. You have the best eye and face tracking implementation on the market, please let us use it. There is a sizable audience who will buy the headset just for it. I personally know multiple people who are not buying the headset simply because you locked those features out. No raw camera access is needed, just abstracted blendshapes values. You will make the headset so much more useful if you do this simple thing.

Loading USDZ asset into Model3D causes visionOS 2.0 beta 5 to crash
We've recently discovered that our app crashes on startup on the latest visionOS 2.0 beta 5 (22N5297g) build. In fact, the entire field of view would dim down and visionOS would then restart, showing the Apple logo. Interestingly, no app crash is reported by Xcode during debug. After investigation, we have isolated the issue to a specific USDZ asset in our app. Loading it in a sample, blank project also causes visionOS to reliably crash, or become extremely unresponsive with rendering artifacts everywhere. This looks like a potentially serious issue. Even if the asset is problematic, loading it should not crash the entire OS. We have filed feedback FB14756285, along with a demo project. Hopefully someone can take a look. Thanks!

LiDAR Projector Pattern iPhone 15 Pro vs. 12 Pro – Research Project Question
Dear Apple Team, I’m a high school student (vocational upper secondary school) working on my final research project about LiDAR sensors in smartphones, specifically Apple’s iPhone implementation. My current understanding (for context): I understand Apple’s LiDAR uses dToF with SPAD detectors: A VCSEL laser emits pulses, a DOE splits the beam into a dot pattern, and each spot’s return time is measured separately → point cloud generation. My specific questions: How many active projection dots does the LiDAR projector have in the iPhone 15 Pro vs. iPhone 12 Pro? Are the dots static or do they shift/move over time? How many depth measurement points does the system deliver internally (after processing)? What is the ranging accuracy (cm-level precision) of each measurement point? Experimental background: Using an IR night vision camera, I counted approximately 111 dots on the 15 Pro vs. 576 dots on the 12 Pro. Do these match the internal specifications? Photos of my measurements are available if helpful. Contact request: I would be very grateful if you could connect me with an Apple engineer or ARKit specialist who works with LiDAR technology. I would love to ask follow-up questions directly and would be happy to provide my contact details for this purpose. These specifications would be essential for my research paper. Thank you very much in advance! Best regards, Max! Vocational Upper Secondary School Hans-Leipelt-Schule Donauwörth Research Project: “LiDAR Sensor Technology in Smartphones”

Photogrammetry Session - new model?
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

Enterprise API with Education Account
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

Reality Composer Timeline unfinished
the timeline editor feels often unfinished. Setting the time cursor to a different time is often not reflected in the preview. You either have to click a clip or wait. sometimes the cursor even disappears, eg. when switching tabs to shadergraph Not being able to select and move multiple clips is missing. There is also no snapping to clips or time cursor as found in other tools. And then there is the timeline compile bug https://developer.apple.com/forums/thread/810868 The timeline as it is, is a good start but it definitely needs some more love to be on par with other commercial tools like Unity or After Effects.

fileImporter issue in visionOS with iPhone app (that can run on visionOS)
Happy new year to all! I have created an iOS app that also runs on Apple Vision Pro. On iOS, when you activate the fileImporter modal, you can swipe down the modal in iOS to dismiss. However, in visionOS, this same modal CANNOT be swiped down to cancel/dismiss. If you are drilled deep into a file hierarchy, you have to navigate back to the top level to tap X to dismiss. Is there a way to add swipe down to the visionOS implementation of fileImporter, or any other workaround so the user doesn't have to navigate back to the top to dismiss? Again, this is not a visionOS app but an iOS app compatible for use in Vision Pro. Thanks!

visionOS pushWindow being dismissed on app foreground
We seen to have found an issue when using the pushWindow action on visionOS. The issue occurs if the app is backgrounded then reopened by selecting the apps icon on the home screen. Any window that is opened via the pushWindow action is then dismissed. We've been able to replicate the issue in a small sample project. Replication steps Open app Open window via the push action Press the digital crown On the home screen select the apps icon again The pushed window will now be dismissed. There is a sample project linked here that shows off the issue, including a video of the bug in progress

The AccessoryAnchor transform does not match any of the Accessory.LocationName options.
I am using AccessoryTrackingProvider from ARKit to get the transform of the PSVR2 controller via originFromAnchorTransform of the AccessoryAnchor. I also am trying to use AnchorEntity on the controller using RealityKit However, none of the three options for Accessory.LocationName, which should be used to define the AnchorEntity target, seem to match the position on the controller which is being sent from ARKit. The picture attached is showing two transforms: RealityKit - using .gripSurface to define the AnchoringComponent.Target.accesssory location. ARKit - using originFromAnchorTransform for AccessoryTrackingProvider. They are not aligned at the same point. As for the other options of Accessory.LocationName, using .aim is located at the tip of the controller and .grip is the same position as .gripSurface but with a different orientation. I am wondering why there is not an option for Accessory.LocationName that actually matches the transform captured by ARKit?

VisionOS 2 - Screen Capture with passthrough
We're trying to switch from using main camera access on Arkit to screen-capture with passthrough however we're facing some issues and it seems a bit complicated to debug. We have set up a broadcast Extension, set up some logs on the sample Handler but we get nothing in the console nor that the recording starts, we set up the picker as well and we can see our extension in the control center as one of the choices but clicking start, results in it stopping in less than one second after. The only message that is rather contradictory we see in the console.app is the following [INFO] -[RPRecordingManager getSystemBroadcastExtensionInfo:]_block_invoke:1333 Extension has passthrough license and just right after [INFO] -[RPRecordingManager getSystemBroadcastExtensionInfo:]_block_invoke:1336 Extension does not have passthrough license

With manipulation component, once you let go, how to prevent the entity from disappearing while animating it back into the volume
So with the new ManipulationComponent, we can choose "stay" and then if you drag it out of your volume, once you let go it will instantly disappear. We can "animate" it back to inside the volume, eg.: content.subscribe(to: ManipulationEvents.WillRelease.self) { event in Entity.animate( .easeInOut(duration: 1), body: { event.entity.position = [0, 0.2, 0] }, completion: {} ) }, Howeve,r for the duration that it travels outside of the volume it's invisible the whole time. In this apple video, it seems to be visible when dragging and when letting go, but perhaps that's not a volume they're dragging it out of? https://youtu.be/VtenPKrvPOU?si=y1zoZOs2IMyDzOm6&t=1748 Does anyone know how to keep the entity visible even when after letting the entity go while you animate it back towards inside of your volume?

Guided Access - Detect when setup (Eyes + Hands) is done
Hello, I am building a kiosk-style app for VisionOS which will be used in Guided Access mode, to be given to various visitors. So each of them will do hands + eyes setup, standard Guided Access thing. I want my experience to auto-start playing content when setup is done. I looked everywhere, but found no way do detect whether setup is complete? Also adding any kind of interface to start the app manually is risky, since buttons etc remain visible an interactable WHILE setup takes place. Delay-based approach also wont work, since setup can be skipped, or failed, or be done quickly, slowly... So it takes between 10 seconds and a few minutes. So the question is - is there any way to get notification, or check some bool or something that will tell me that Hands + Eyes setup in Guided mode is complete (or skipped)? Thanks in advance!

Access UltraWideCamera when ARSession is running
ARSession provides video stream from the wide angle camera. If ARSession uses the ultra wide camera at the same time, ARSession may provide video stream from that camera, otherwise AVCaptureSession with an ultra wide camera should be allowed to launch. It would be very very useful if we can access different cameras while ARSession is running. We'd like to cooperate with you if possible. Steps to reproduce: run an AVCaptureSession and then run an ARSession. The AVCaptureSession stops.

Scene not found after changes in Reality Composer Pro
randomly, the app does not work after small changes in Reality Composer. Small changes like scaling a object a tiny bit. to fix the error, i have to change another element in reality composer and hope for the best. if this does not help, i change (transform) something else, or deactive/activate something to get the project working again. I can't see a pattern why the Reality Composer Project sometimes gets in a state where it does not compile anymore.

How to fix "Sample 0 missing LiDAR point cloud!" error?
I'm trying to run a PhotogrammetrySession based on photos taken in an AVCaptureSession and stored as .heic files. When I load the files I'm always seeing the error "Sample 0 missing LiDAR point cloud!" showing up for each individual sample. Debugging shows that sample.depthDataMap is populated, also the .heic contains depth data which can be extracted using e.g. heif-convert on my Mac. Comparing the .heic I created to one of the ObjectCaptureSession which doesn't show the LiDAR warning, I noticed the only difference being the HEIC information here: So my questions are: Are these the missing information in my manual capture causing this warning? Can I somehow add these information in an AVCaptureSession? Do these information allow better photogrammetry results?

Issue with tracking multiple images using ARKit on VisionOS
We are using the ARKit image tracking feature on visionOS 2.0 with three pre-registered images. The image tracking works, but only one image is actively tracked at a time. When more than one target image is visible to the camera, it has difficulty detecting and tracking the other images. Is this the expected behavior in visionOS, or is there something we need to do to resolve this issue?

Collision Detection Fails After Anchoring ModelEntity to Hand in VisionOS
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()) }

How to display stereo images in Apple Vision Pro?
Hi community, I have a pair of stereo images, one for each eye. How should I render it on visionOS? I know that for 3D videos, the AVPlayerViewController could display them in fullscreen mode. But I couldn't find any docs relating to 3D stereo images. I guess my question can be brought up in a more general way: Is there any method that we can render different content for each eye? This could also be helpful to someone who only has sight on one eye.

How to request several models simultaneously
I am using HelloPhotogrammetry in Xcode I can make one model with something like HelloPhotogrammetry.main([path_to_folder_of images, path_to_output/model.usdz, "-d", "medium", "-o", "unordered", "-f", "high" ]) But how would I request several models simultaneously? I only want to vary the detail. [ ("/Users/you/Desktop/model_medium.usdz", detail: .medium), ("/Users/you/Desktop/model_full.usdz", detail: .full), ("/Users/you/Desktop/model_raw.usdz", detail: .raw ]
