At the moment the map kit APls only support non-volumetric maps (i.e. in a window or in a volume, but on a 2D surface). Is support for 3D volumetric maps in VisionOS in the works? And if so when can we expect it to be available?

If I correctly understand, a new Enterprise API has been introduced In visionOS 26 allowing to fix windows to the user frame of reference, implementing a something like an "head up display", with the window tracking the user movements. Is this API only available to enterprise applications, and if so is there a plan to make it available for every kind of app?

There a way to use contentCaptureProtected with Quick Look on VisionOS 26? Or exist a way to see a spatial photo with Quick Look without sharing options ?

When viewing an immersive space and I open a spatial photo in Quick Look, which hides the entire app interface to show the photo. Is there a memory limit? If the inmersive space is not active, the application keep the interface.

I really love the immersive environments, but I don’t have experience with creating them. Do you have resources or tutorials you can recommend for creating these from scratch? I’ve seen the sample projects and videos, but they usually start in the middle, assuming you already have the assets created.

Hello everyone, I'm a new developer and I'm still learning the foundations of Swift and SwiftUI while building my first app. Today I wanted to ask you how to implement AR Quixck Views inside my app. I wanna be able to dynamically preview AR objects in a dedicated view, however, I don't seem to have understood where and how to locate AR objects inside my project. I tried including them in the Assets folder of the project, or in the Recources folder, or within the main folder of my project alongside the MyAppApp.swift file. None of the methods I used seemed have worked in that none of the objects was ever located. I made sure to specify the path to the files every time, but somehow the location isn't recognized. I also tried giving no path so that the app would search for the files in their default location (which I apparently haven't grasped yet), but still my attempt failed. I don't have the code sample on me at the moment, but I will write a followup comment on this post to show you what I wrote in case anyone was interested in debugging my code. Meanwhile, if anyone would be so kind to point me at the support article or to comment below the sample code they used in their app, I would very much appreciate it, so that I can start debugging. Thank you for reading this, I appreciate you.

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?

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

Hi, since iOS 18 UnlitMaterial and ShaderGraphMaterial have the option to disable tone mapping, e.g via https://aninterestingwebsite.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!

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?

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.

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

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'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)

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?

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!

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?

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:

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.
