Any way to extend the video recording time in Reality Composer Pro from 3:00 to any longer value, such as editing preferences in Terminal or other workaround? Is there any way to use the strap and a USB-C cable as a live video stream input source that would mirror to Quicktime or some other video capture tool? I am assuming there is no online documentation or user manual for the strap, but please correct me if I'm wrong. Thank you.

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?

So it seems to be that there is a contradiction between how ARKit defines UIDeviceOrientation.landscapeRight, and the actual definition of UIDeviceOrientation.landscapeRight in the UIKit documentation. In the ARKit documentation for ARCamera.transform, it says the following: This transform creates a local coordinate space for the camera that is constant with respect to device orientation. In camera space, the x-axis points to the right when the device is in UIDeviceOrientation.landscapeRight orientation—that is, the x-axis always points along the long axis of the device, from the front-facing camera toward the Home button. The y-axis points upward (with respect to UIDeviceOrientation.landscapeRight orientation), and the z-axis points away from the device on the screen side. Going through the same link, we see the definition of UIDeviceOrientation.landscapeRight given as: The device is in landscape mode, with the device held upright and the front-facing camera on the right side. There seems to be a conflict in the two definitions, that has already been asked and visualized in this StackOverflow thread The resolution of that answer says that ARKit landscapeRight, unlike what is given in UIDeviceOrientation.landscapeRight, has home button on the right, as stated in the ARCamera.transform documentation. It says that more details are given in this StackOverflow thread, but this thread talks about the discrepancy between the definitions of landscapeRight in UIDeviceOrientation and UIInterfaceOrientation, and not anything related to ARKit. So I am wondering, why does ARKit definition of landscapeRight contradict with that of UIDeviceOrientation despite explicitly mentioning it? Is it just a mistake by Apple developers that hasn't been resolved even after so long?

Hello all, I saw this interesting VisionOS app: https://apps.apple.com/us/app/splitscreen-multi-display/id6478007837 I was wondering if there was any documentation on the Swift APIs that were used to create this app.

Hey there, since SceneView has been marked as „deprecated“ for SwiftUI, I‘m wondering which alternatives should be considered for the following situation: I have a SwiftUI app (for iOS and iPadOS) where users can view (with rotate, scale, move gestures) 3D models (USDZ) in a scene. The models will be downloaded from web backend and called via local URL paths. What I tested: I‘ve tried ARView in .nonAR mode, RealityView, however I didn‘t get the expected response -> User can rotate, scale the 3D models in a virtual space. ARView in nonAR mode still shows the object like in normal AR mode without camera stream. I tried to add Gestures to the RealityView on iOS - loading USDZ 3D models worked but the gestures didn’t). Model3D is only available for visionOS (that would be amazing to have it for iOS) I also checked QuickLook Preview however it works pretty strange via Filepicker etc, which is not the way how the user should load the 3D models in my app. Maybe I missed something, I couldn’t find anything which can help me. I‘m pretty much stucked adopting the latest and greatest frameworks/APIs in my App and taking the next steps porting my app to visionOS. Long story short 😃: Does someone have an idea what is the alternative to SceneView for USDZ 3D models? I appreciate your support!! Thanks in advance!

Hello, For GuessTogether source code, it seems like the code assumes that you're already in a FaceTime call before pressing the custom SharePlay button (labeled "Play Guess Together"). If not already on a FaceTime call, my Apple Vision Pro and the visionOS simulator both do nothing after throwing warnings. Is this intended behavior? If so, how do I make it so that pressing the button can also initiate FaceTime calls? Is this allowed? Thank you!

Hello, I'm working on a visionOS project that uses Reality Composer Pro, and we are managing our project files with Git. We've noticed that simply opening and closing the Reality Composer Pro application consistently generates changes in the following files, even when no explicit modifications have been made by the developer: {ProjectName}/Packages/RealityKitContent/Package.realitycomposerpro/PluginData/*******/ShaderGraphEditorPluginID/ShaderGraphEditorPluginID {ProjectName}/Packages/RealityKitContent/Package.realitycomposerpro/WorkspaceData/SceneMetadataList.json Could you please clarify the purpose of these files? Why do they appear as modified when no direct changes are made from our end? More importantly, is it safe to add these files to our .gitignore to prevent them from being tracked by Git? We are concerned that ignoring these files might lead to unexpected issues or inconsistencies when other team members pull the latest changes, especially if these files contain critical project metadata or state that needs to be synchronized. Any insights or recommended best practices for managing Reality Composer Pro projects with Git would be greatly appreciated. Thank you for your time and assistance.

My ARViewContainer code is not working. I don't know how to debug the issue and I don't know or see where my results is going to. I need help to resolve this issue. please help debug. See code below:

Hi all, I'm currently developing a real-time object reconstruction app using ARKit. The goal is to scan large objects using ARKit’s depth and transform data, and generate a point cloud. However, I’m facing a major challenge - Transform Drift / World Alignment Issues The localToWorld transform provided by ARKit frequently seems to drift or become unstable across frames. This results in misaligned point clouds even when the device is moved slowly or kept relatively still. In some cases, a static surface scanned over a few seconds results in clearly misaligned fragments. This makes it difficult to accurately stitch a multi-frame point cloud. I have experimented with various lighting conditions and object textures, but the issue persists in all cases. At times, the relative error between frames reaches up to 20 cm, while in other instances the error is minimal; however, the drift gradually accumulates over time, leading to an overall enlargement of the reconstructed object. I have attached images of both cases here. Questions: Are there specific conditions under which ARKit’s world transform is expected to drift? Is there a way to detect or recover from this drift during runtime? Any best practices for maintaining consistent tracking during scanning or measurement sessions?

Hi, I’m currently using Reality Composer Pro on macOS, and I’m trying to work with particle emitters using only the built-in tools — no Xcode, no custom Swift code. Here’s what I’m trying to achieve: 1. Is it possible to trigger a particle emitter with a tap gesture, directly inside Reality Composer Pro? 2. Can I add a particle emitter to a timeline, so that it emits at a specific time during an animation or behavior sequence? 3. Most importantly, is there a way to precisely control emission behavior — such as when particles start or stop — using visual and intuitive controls, without scripting? My goal is to set up particle effects that are interactive and timeline-controlled, but managed entirely through Reality Composer Pro’s GUI, not through code. Any suggestions, tips, or examples would be very helpful. Thanks in advance!

I am trying to run widgets on visionOS 26. Specifically I am trying to pin them to the simulator room's walls, however I am unable to do so. Is this a limitation with the visionOS simulator right now, or am I missing a trick here?

I'm seeing this error while attempting to compile my VisionOS app under Xcode 26. My existing code looks like: let (naturalSize, formatDescriptions, mediaCharacteristics) = try? await videoTrack.load(.naturalSize, .formatDescriptions, .mediaCharacteristics) This is now giving a compiler error: Type of expression is ambiguous without a type annotation I don't see that anything that was changed or deprecated in the latest version. Also loading the properties individually seems to work fine i.e.: let naturalSize = try? await videoTrack.load(.naturalSize) let formatDescriptions = try? await videoTrack.load(.formatDescriptions) let mediaCharacteristics = try? await videoTrack.load(.mediaCharacteristics)

Can I apply .scrollInputBehavior(.enabled, for: .look) to a WebView (wrapped UIViewRepresentable) in a visionOS 26 app? I tried it myself, but I couldn't do it, so I would like to know if there is any way to do this. Best regards.

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

I am trying to loop my videoMaterial. I have researched the AXQueuePlayer and AVPlayerLooper and tried to implement them into my code. Please see attached. There are no errors showing up but the videoMaterial is no longer working. Please see the attached for the working code that plays the videoMaterial. I am stumped can anyone help me solve this? Thank you.

With the new ImagePresentationComponent in visionOS 26, how can text/overlays be shown on top of the image as seen in the Spatial Gallery app?

Hi, since iOS 18 UnlitMaterial and ShaderGraphMaterial have the option to disable tone mapping, e.g via https://developer.apple.com/documentation/realitykit/unlitmaterial/init(applypostprocesstonemap:) Is it possible to do the same for CustomMaterial? I tried initializing a CustomMaterial based on an UnlitMaterial where tone mapping is disabled, like so: let unlitMat = UnlitMaterial(applyPostProcessToneMap: false) let customMaterial = try CustomMaterial( from: unlitMat, surfaceShader: surfaceShader, geometryModifier: geometryModifier ) but that does not seem to work. The colors of my texture still look altered in comparison to a plain UnlitMaterial or a ShaderGraphMaterial where its disabled. Any hints? Thank you!

Hi Nathaniel, I spoke with you yesterday in the WWDC lab. Thanks for chatting with me! Is it possible to get a link to a doc that has some key metrics I'd find in a RealityKit trace so I know if that metric is exceeding limits and probably causing a problem? Right now, I just see numbers and have no idea if a metric is high or low :). This is specifically for a VisionOS app. Thanks, Bob

I am still not finding resources to know how to replace hands in a full immersive Space.... I reached the goal by creating a ARKit session that can detect the USDZ hand mesh Joints and connect to the hand-tracked-joints.... but I feel that's not the best solution... I really want to use the RealityKit potential to track and replace hands (with USDZ skinned ones) in an immersive environment, but the only resources I found are from November 2023.... :( Can someone help me?
