is it possible to dynamically update ModelPositionOffset of GeometryModifier with a depth map image? in my code I set up the parameter for "DepthMapTexture" universal input node and tried setting the depth map for depthTextureResource. I have 2 DrawableQueues. One for setting InputTexture, and one for setting DepthMapTexture. This only shows the part that concerns setting DepthMapTexture this is where I define the plane entity. and this is the shader graph what I noticed with GeometryModifier is that, the depthMap image has to be same as input image's dimensions. and when I applied this material to usdz file, with pre-assigned image and depth map from RCP, and loaded that Entity from code, depth map was applied correctly. what I am unsure is that if it is impossible to define a model entity from code, apply ShaderGraphMaterial from RCP, and dynamically update the image used in GeometryModifier. Maybe I'm missing something when defining Entity, something that allows geometric modifications?

First, I scan first room using the roomplan api. Because I need scan second room, I stop it by “captureSession.stop(pauseARSession: false)”, I think the Arsession is continue work at that time. Second, before the another room will scan, I want to run another ARView. (in order to detect some objects which are not detected by Roomplan in first room) But, at this time, the second ARView(there is an ARView in roomplan, I think) will always black screen, can’t normally work. This is the question I want to resolve. Please help me let the second ARView go well.

I have tested the MagnifyGesture code below on multiple devices: Vision Pro - working iPhone - working iPad - working macOS - not working In Reality Composer Pro, I have also added the below components to the test model entity: Input Target Collision For macOS, I tried the touchpad pinch gesture and mouse scroll wheel, but neither approach works. How to resolve this issue? Thank you. import SwiftUI import RealityKit import RealityKitContent struct ContentView: View { var body: some View { RealityView { content in // Add the initial RealityKit content if let immersiveContentEntity = try? await Entity(named: "Immersive", in: realityKitContentBundle) { content.add(immersiveContentEntity) } } .gesture(MagnifyGesture() .targetedToAnyEntity() .onChanged(onMagnifyChanged) .onEnded(onMagnifyEnded)) } func onMagnifyChanged(_ value: EntityTargetValue<MagnifyGesture.Value>) { print("onMagnifyChanged") } func onMagnifyEnded(_ value: EntityTargetValue<MagnifyGesture.Value>) { print("onMagnifyEnded") } }

As far as I know, Apple hasn’t opened access to the Vision Pro camera for developers yet, so I’m trying to find possible workarounds within the current capabilities. I’m wondering if there’s any way to apply a mesh to a person in the scene in Vision Pro, or if there’s an alternative approach to roughly detect a human shape in front of the user?

Dear Apple Engineers, I am working on a project in visionOS and need to implement a curved surface effect for video playback, where the width of the surface can be dynamically adjusted. Specifically, I want the video to be displayed on a curved surface (similar to a scroll unfolding), and the user should be able to adjust the width of this surface. I have the following specific questions: How can I implement a curved surface for video playback and ensure the video content is not stretched or distorted on the surface? How can I create a dynamic curved surface (such as a bending plane) in RealityKit or visionOS, where the width can be adjusted by the user? Is it possible to achieve more complex curved surface effects (such as scroll unfolding or bending) using Shaders or other techniques? Thank you very much for your help!

Can you help to write a code able to pick an element a bit far from me, then bring it near to me, flick it a bit and then send it back to its original position when I release it? Thanks a lot, Christophe

When I show a window while a sky sphere is shown, the handles to drag/close/resize the window are hidden. The colliders still work, so they are there, but only the visuals are hidden. I already know from another project, that this also happens to volumes. They only appear once you get closer to the window or if the sky sphere gets removed. Is this a known issue or is there a fix for that? .persistentSystemOverlays(.visible)does not fix it Xcode 16.3.0 Beta, visionOS 2.4

When building a multiplayer Tabletop game, the documentation includes how to attach a custom TabletopNetworkSessionCoordinator, which could be used in addition to TabletopGame.MultiplayerDelegate. But so far, we have been unable to create these types of custom coordinators or have a delegate that works. Our current setup with our generic GroupActivity works by sending the session to TabletopGame's coordinateWithSession method (like in the current sample project), but we didn't find a way to access and control, for example, the arbiter, seats, player events, among other features mentioned on https://developer.apple.com/documentation/tabletopkit/tabletopnetworksession. Is correct to expect having access to the participants, messenger, or journal without having to maintain a parallel coordinator?   possibly we are missing something here; any suggestions?

In the DestinationVideo demo, the onAppear in UpNextView is triggered again when it is closed, but I only want it to be triggered once. How can I achieve this? Alternatively, I would like to capture the button click events in the player menu, as shown in the screenshot below.

Environment Xcode: 16.2 VisionOS SDK 2.4 Swift 6.1 Targets: Apple Vision Pro (immersive space) Frameworks: ARKit, RealityKit, SwiftUI What I’m Trying to Do I have a view-model class PlacementManager that holds two AR providers: private var worldTracking: WorldTrackingProvider private var planeDetection: PlaneDetectionProvider I want to dynamically replace these providers in a setEnvironment(_:) method (so I can save/clear a JSON scene and restart ARKit). What’s Happening If I declare them as : private let worldTracking = WorldTrackingProvider() private let planeDetection = PlaneDetectionProvider() I get compile-errors when I later do: self.worldTracking = newWorldTracking // Cannot assign to property: 'worldTracking' is a 'let' constant If I change them to un-initialized vars: private var worldTracking: WorldTrackingProvider private var planeDetection: PlaneDetectionProvider then in my init() I get: self used in property access 'worldTracking' before all stored properties are initialized Code snipet @Observable final class PlacementManager : ObservableObject { private var worldTracking: WorldTrackingProvider private var planeDetection: PlaneDetectionProvider // … other props … @MainActor init() { // error: self.worldTracking used before init… planeAnchorHandler = PlaneAnchorHandler(rootEntity: root) persistenceManager = PersistenceManager( worldTracking: worldTracking, rootEntity: root ) // … } @MainActor func setEnvironment(env: Environnement) async { let newWorldTracking = WorldTrackingProvider() let newPlaneDetection = PlaneDetectionProvider() try await appState!.arkitSession.run( [ newWorldTracking, newPlaneDetection ] ) self.worldTracking = newWorldTracking self.planeDetection = newPlaneDetection // … } } What I’ve Tried Giving them default values at declaration (= WorldTrackingProvider()) Initializing them at the top of init() before any use Passing the new providers into arkitSession.run(...) My Question What is the recommended Swift-style pattern to declare and reassign these ARKit provider properties so that: They’re fully initialized before use in init(), and I can swap them out later in setEnvironment(...) without compiler errors? Any pointers (or links to forum threads / docs) would be greatly appreciated!

When I run my app from Xcode on a device running iOS 26, the roomplan capture is corrupted and the recording is green and purple. This issue does not occur when I use an older version of iOS or when I run the app via testFlight or the App Store.

Currently I am using mixed style immersive view to place both my WindowView(plain style) and ImmersiveView content together. The issue is that the rendering depth testing may always let the virtual content block my normal WindowView. Is it possible to manually set windowedVIew always displays in the front of my virtual view in mixed style immersion? (I know modelSortGroup but it doesn't quite fits here) Or if I can dynamically change the .progressive value when the immersive space is open (set the value to zero means .mixed itself right?)

I want to record animation with entity, then export it to .usd without using Reality Composer Pro, how to achieve that?

I would like to integrate the object capture API with a ML model for analysis. So, i will need to get the current frame into CG images for further process. Thanks in advance !

prefetching logic for UICollectionView on VisionOS does not work. I have set up a Standalone test repo to demonstrate this issue. This repo is basically a visionOS version of Apple's guide project on implementation of prefetching logic. in repo you will see a simple ViewController that has UICollectionView, wrapped inside UIViewControllerRepresentable. on scroll, it should print 🕊️ prefetch start on console to demonstrate func collectionView(_ collectionView: UICollectionView, prefetchItemsAt indexPaths: [IndexPath]) is called. However it never happens on VisionOS devices. With the same code it behaves correctly on iOS devices

Hello, I checked following documentations. Vision | Apple Developer Documentation Discover Swift enhancements in the Vision framework - WWDC24 - Videos - Apple Developer I saw Vision Framework is available on visionOS. So I want to know that if it's possible using Vision Framework on visionOS for tracking human and animal body poses. Or are there some limits to use this on visionOS?

Can we constrain or clamp translation with the new ManipulationComponent? For example, allow free movement within certain bounds.

I want to step into portal world. I've know PortalCrossingComponent can make an entity to cross portal, but how to make device cross into portal world?

The initial startup of visionOS 26 after install is glacially slow.

Hi everyone, I'm developing a MR Vision Pro app where I’d like to anchor virtual objects (such as UI elements) around the user's arm. However, I’ve noticed that Vision Pro seems to mask out the area where the user’s real arm is, hiding virtual content in that region so that you see your real arm. Is there a way to render virtual elements on the user's arm—so that it looks like the object is placed directly on the arm despite the real-world passthrough? I was hoping there might be a way to adjust the depth or behavior of this masked-out region. Any insights or workarounds would be greatly appreciated! Thanks :)
