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.

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 AR based app I am working on right now is experiencing an issue. Sometimes, the AR session fails with a call to my ARSessionObserver's session(_ session: ARSession, didFailWithError error: Error) with the following error: Error Domain=com.apple.arkit.error Code=102 "Required sensor failed." NSLocalizedFailureReason="A sensor failed to deliver the required input.," NSLocalizedRecoverySuggestion="Make sure that the application has the required privacy settings." The underlying error seems to point to the CoreMotion framework: Domain=CMErrorDomain Code=102 "(null) Some people seem to have experienced this issue and solved it by making sure that the Compass Calibration switch is ON in Settings > Privacy > Location Services > System Services. For context, the ARWorldTrackingConfiguration.worldAlignment is set to .gravity The thing is it is already ON when I experience this issue. I also noticed that this issue happens way more often on the iPhone 16e than in any other device. Has anyone had similar experiences? I am looking for a way to prevent this error from happening (ideally) or handling in a way that does not affect the user. Any help is appreciated

When assigning a ManipulationComponent to an Entity SceneEvents.WillRemoveEntity will be called for that Entity. Expected Behavior: the Entity is not (even if temporarily) removed from the Scene and no SceneEvents will be triggered as a result of assigning a ManipulationComponent. FB20872220

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?

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”

Spatial photo in RealityView has a default corner radius. I made a parallel effect with spatial photos in ScrollView(like Spatial Gallery), but the corner radius disappeared on left and right spatial photos. I've tried .clipShape and .mask modifiers, but they did't work. How to clip or mask spatial photo with corner radius effect?

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://aninterestingwebsite.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.

In visionOS, I'm trying to create an immersive environment which would feature several spheres in which immersive movies are visible. I'm starting from a sample code which creates a sphere, sets an immersive movie as its material, and opens it as an immersive environment. This works fine. But if I create a sphere in an open immersive environment using Reality Composer Pro and sets its material to an immersive movie, I can see the movie on the sphere while I move outside of it but if I try to get inside the sphere, it disappears. What would be the right way of doing this ?

I sketched a idea for a project in Reality Composer on my iPad, thinking when I had a chance to sit down I would work it up in Xcode. However, when I got back to my computer, I discovered I cannot open a file created in Reality Composer (or the exported Reality file) in Reality Composer Pro. Am I missing something obvious here, because this seems like a huge oversight. If anyone, can let me know how to open a file created in Reality Composer in Reality Composer Pro, I would greatly appreciate it. Partly, because there seems to be objects available in Reality Composer that are not in Reality Composer Pro. Thanks Stan

Error: RoomCaptureSession.CaptureError.exceedSceneSizeLimit Apple Documentation Explanation: An error that indicates when the scene size grows past the framework’s limitations. Issue: This error is popping up in my iPhone 14 Pro (128 GB) after a few roomplan scans are done. This error shows up even if the room size is small. It occurs immediately after I start the RoomCaptureSession after the relocalisation of previous AR session (in world tracking configuration). I am having trouble understanding exactly why this error shows and how to debug/solve it. Does anyone have any idea on how to approach to this issue?

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?

With iOS26 unveiled, has anyone noticed or found any changes related to RoomPlan? I can't find anything myself, which is disappointing. Has anyone found any improvements or changes?

In courses like Compose interactive 3D content in Reality Composer Pro Realitykit Engineers recommended working with Reality Composer Pro to create RealityKit packages to embed in our Realitykit Xcode projects. And, comparing the workflow to Unity/Unreal, I can see the reasoning since it is nice to prepare scenes/materials/assets visually. Now when we also want to run a Xcode Cloud CI/CD pipeline this seems to come into conflict: When adding a basic *.usdz to the RealityKitContent.rkassets folder, every build we run on Xcode cloud fails with: Compile Reality Asset RealityKitContent.rkassets ❌realitytool requires Metal for this operation and it is not available in this build environment I have also found this related forum post here but it was specifically about compiling a *.skybox.

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.

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

Platform: visionOS 2.6 Framework: RealityKit, SwiftUIComponent: ImagePresentationComponent I’m working with the new ImagePresentationComponent from visionOS 26 and hitting a rendering limitation when switching to .spatialStereoImmersive viewing mode within a WindowGroup context. This is what I’m seeing: Pure immersive space: ImagePresentationComponent with .spatialStereoImmersive mode works perfectly in a standalone ImmersiveSpace Mode switching API: All mode transitions work correctly (logs confirm the component updates) Spatial content: .spatialStereo mode renders correctly in both window and immersive contexts. This is where it’s breaking for me: Window context: When the same RealityView + ImagePresentationComponent is placed inside a WindowGroup (even when that window is floating in a mixed immersive space), switching to .spatialStereoImmersive mode shows no visual change The API calls succeed, state updates correctly, but the immersive content doesn’t render. Apple’s Spatial Gallery demonstrates exactly what I’m trying to achieve: Spatial photos displayed in a window with what feels like horizontal scroll view using system window control bar, etc. Tapping a spatial photo smoothly transitions it to immersive mode in-place. The immersive content appears to “grow” from the original window position by just changing IPC viewing modes. This proves the functionality should be possible, but I can’t determine the correct configuration. So, my question to is: Is there a specific RealityView or WindowGroup configuration required to enable immersive content rendering from window contexts that you know of? Are there bounds/clipping settings that need to be configured to allow immersive content to “break out” of window constraints? Does .spatialStereoImmersive require a specific rendering context that’s not available in windowed RealityView instances? How do you think Apple’s SG app achieves this functionality? For a little more context: All viewing modes are available: [.mono, .spatialStereo, .spatialStereoImmersive] The spatial photos are valid and work correctly in pure immersive space Mixed immersive space is active when testing window context No errors or warnings in console beyond the successful mode switching logs I’m getting Any insights into the proper configuration for window-hosted immersive content

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!

Is there any interest in this forum for those developing for the spatial web and safari. I can't seem to find any posts that are relevant here.

I have two RealityView: ParentView and When click the button in ParentView, ChildView will be shown as full screen cover, but the camera feed in ChildView will not be shown, only black screen. If I show ChildView directly, it works with camera feed. Please help me on this issue? Thanks. import RealityKit import SwiftUI struct ParentView: View{ @State private var showIt = false var body: some View{ ZStack{ RealityView{content in content.camera = .virtual let box = ModelEntity(mesh: MeshResource.generateSphere(radius: 0.2),materials: [createSimpleMaterial(color: .red)]) content.add(box) } Button("Click here"){ showIt = true } } .fullScreenCover(isPresented: $showIt){ ChildView() .overlay( Button("Close"){ showIt = false }.padding(20), alignment: .bottomLeading ) } .ignoresSafeArea(.all) } } import ARKit import RealityKit import SwiftUI struct ChildView: View{ var body: some View{ RealityView{content in content.camera = .spatialTracking } } }
