I want to let users place 2D/3D “artworks” on detected walls and have them reappear in exactly the same real‑world spot after quitting and relaunching the app (like widgets do, but for my own entities).Environment: Xcode 26, visionOS 2.0, RealityKit + ARKitSession/WorldTrackingProvider Entities are parented to a holder that’s aligned to a wall via plane/mesh raycasts. What I’ve tried: Create a WorldAnchor at placement, save UUID + full 4×4 transform On next launch, re-create the WorldAnchor (or set the saved transform) and attach the entity Gate restore on relocalization/mesh updates and disable all raycast/search after restore Issue: After relaunch, placement still resolves relative to current device pose, not the same wall position. Questions: Is there a public API in visionOS 2.0 to persist app‑managed world anchors across sessions (room‑fixed), e.g., AnchorStore or equivalent? If not, what’s the recommended pattern to reliably restore wall‑anchored content? Are persistence features mentioned for widgets/windows available to third‑party RealityKit entities?

Do you retain a reference to your content (RealityViewContent) events? For example, the Manipulation Events docs from Apple use _ to discard the result. In theory the event should keep working while the content is alive. _ = content.subscribe(to: ManipulationEvents.WillBegin.self) { event in event.entity.components[ModelComponent.self]?.materials[0] = SimpleMaterial(color: .blue, isMetallic: false) } _ = content.subscribe(to: ManipulationEvents.WillEnd.self) { event in event.entity.components[ModelComponent.self]?.materials[0] = SimpleMaterial(color: .red, isMetallic: false) } We could store these events in state. I've seen this in a few samples and apps. @State var beginSubscription: EventSubscription? ... beginSubscription = content.subscribe(to: ManipulationEvents.WillBegin.self) { event in event.entity.components[ModelComponent.self]?.materials[0] = SimpleMaterial(color: .blue, isMetallic: false) } The main advantage I see is that we can be more explicit about when we remove the event. Are there other reasons to keep a reference to these events?

I want to display a model image in the windowGroup window. This image is not unique. To display the model image, how should I convert it into an image

Hello, I am currently working on a Unity project for the Apple Vision Pro. I would like to have people passing in front of the virtual objects occlude the virtual objects that are behind. Something similar to this: https://developer.apple.com/documentation/arkit/occluding-virtual-content-with-people I could unfortunately not find any documentation about this. Is it possible to implement body segmentation or occlusion on the Apple Vision Pro? If it's not currently supported, are there plans to add it? Any ideas on how to achieve this with existing tools? Thanks! Mehdi

Hi, When viewing a spatial photo scene on the Apple Vision Pro Photos app, you can tap on the immersive icon on the top right corner to transaction from the window presenting the image as spatial3d to an immersive photo scene with spatial3DImmersive where the window borders disappear. Could someone explain how to achieve that? I tried to do it but once I transition from spatial3d to spatial3DImmersive I can see still see a rectangle around the spatial image. Thanks.

I have a MeshResource and I would like to create a collision component from it. let childBounds = child.visualBounds(relativeTo: self) var childShape: ShapeResource do { // Crashed by the following line instead of throwing a Swift Error childShape = try await ShapeResource.generateConvex(from: childModel.mesh); } catch { childShape = ShapeResource.generateBox(size: childBounds.extents) childShape = childShape.offsetBy(translation: childBounds.center) } Based on this document: https://developer.apple.com/documentation/realitykit/shaperesource/generateconvex(from:)-6upj9 Will throw an error if mesh does not define a nonempty convex volume. For example, will fail if all the vertices in mesh are coplanar.

It's much easier to use custom material to bridge metal shader onto Reality model than using LowLevelTexture does the same thing. Why VisionOS doesn't support this material:

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.

I am creating a vision pro app with a 3D model, it has a mesh hierarchy of head, hands, feet etc. I want the character to look towards the camera, but am not able to access head of character through sceneKit nor reality kit. when I try to print names of the child meshes, it only prints till the character, it does iterate through all the body parts. Can anyone help?

I found some snapshot API in developer documents, like blows: RealityKit / Views and attachments / ARView / /snapshot(saveToHDR:completion:) SceneKit / SCNView / snapshot() Is there a similar API in visionOS？and if not, how can I implement snapshot for realityview and usdz?

I have a visionOS 2 project created on Xcode 16, when I updated to Xcode 26 beta5, I can't build it any more, every time it stuck in process like the picture shows below: Already tried many methods to fix this issue, such as clear build folders, but don't work.

Hello, I am currently developing a Vision Pro VR application with Unreal Engine 5.5. Is it possible to interact with objects (grabbing, clicking on buttons)? I cannot find any information on this. Thank you.

Hi, we would like to create something where you can open multiple volumetric windows and place them in a room, our biggest issue is that we want these windows to be persistent, so when I close and reopen the app, the windows to be in the same position. We can't use immersive spaces because we also want to have the possibility to access the shared space. Is it possible with the current features and capabilities to do that? If yes do you have some advices how can we achieve this? The alternative is if is it possible to open the virtual display in immersive spaces or if we have the possibility to implement our own virtual display.

I have a mesh based animation 3D model, that means every frame it’s a new mesh. I import it into RealityView, but can’t play it‘s animation, RealityKit tells me this model has no animations by using print(entity.availableAnimations).

Hello, I've pre-ordered the Logitech Muse with hopes of developing with it, but have yet to find any documentation relating to the capabilities it will have/any APIs that will be available to take advantage of the Muse. Is anyone aware of what might become available? Thank you in advance.

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?

If I update vision pro size then textfield and button are not update as per its new size. Its working on some scren but not in some screen. Please refer below screenshot for your reference,

I'm trying to add a feature to my app to allow a user to import items from other apps, like Safari, via the share sheet. I've done this many times on iOS/iPadOS easily with a Share Extension. From what I can tell, Xcode tells me share extensions are not available on visionOS - though my experience on device tells me differently (It seems Reminders, Notes & more implement them somehow.) I was finally able to get it working on device only...but I can now no longer test in the simulator, and have not found a way to distribute this app. When attempting to run on the simulator, I get this issue: Please try again later. Appex bundle at /Users/jason/Library/Developer/CoreSimulator/Devices/09A70160-4F4F-4F5E-B679-F6F7D876D7EF/data/Library/Caches/com.apple.mobile.installd.staging/temp.6OAEZp/extracted/LaunchBar.app/PlugIns/LaunchBarShareExtension.appex with id co.swiftfox.LaunchBar.ShareExtension specifies a value (com.apple.share-services) for the NSExtensionPointIdentifier key in the NSExtension dictionary in its Info.plist that does not correspond to a known extension point. When trying to archive an upload to test flight, I get this similar error: Invalid Info.plist value. The value for the key 'DTPlatformName' in bundle LaunchBar.app/PlugIns/LaunchBarShareExtension.appex is invalid. (ID: 207610c7-b7e1-48be-959b-22a43cd32d16) The app is for visionOS only - which I'm thinking might be the problem? The share extension is "Designed For iPhone" and requires me to include iPhone as a run destination. In the worst case I can build an iPhone UI for the app but I'd rather not, as it is very specific to visionOS. Has anyone successfully launched a share extension on a visionOS only app? I have an iPad app with a share extension that shows up fine on visionOS, but the issue seems to be specifically with visionOS only apps.

Dear all, I´m using Unity 6.2 beta and Xcode 16.2. I´m creating a simple framework to use the text to speech functionality in VisionOS from unity. The framework is created in Swift. I create an objective-c wrapper with the following declarations: ... void _initTTS(int); ... I create the framework, import it in Unity and call the functions in a c# wrapper class. The code is as follows: public static class TTSPluginManager { [DllImport("TTS_Vision"] private static extern void _initTTS(int val); ... public static void Initialize() { #if UNITY_VISIONOS _initTTS(0); #else Debug.LogWarning("NativeTTS.Initialize called on a non-iOS platform. Ignoring."); #endif } } I have managed to compile and run the program in the Apple Vision Pro, but I keep on getting the following error: DllNotFoundException: TTS_Vision assembly: type: member:(null) TTSPluginManager.Initialize () (at Assets/Plugins/TTSPluginManager.cs:33) LecturePortalManager.OnCreateStory (Ink.Runtime.Story story) (at Assets/AVRLecture/LecturePortalManager.cs:17) InkLoader.StartStory () (at Assets/AVRLecture/InkLoader.cs:24) InkLoader.Start () (at Assets/AVRLecture/InkLoader.cs:18) If I run the generated code from Xcode, I can see the app in the AVP, but I keep getting a loading error: DllNotFoundException: Unable to load DLL 'TTS_Vision'. Tried the load the following dynamic libraries: Unable to load dynamic library '/TTS_Vision' because of 'Failed to open the requested dynamic library (0x06000000) dlerror() = dlopen(/TTS_Vision, 0x0005): tried: '/TTS_Vision' (no such file) at TTSPluginManager.Initialize () [0x00000] in <00000000000000000000000000000000>:0 at LecturePortalManager.OnCreateStory (Ink.Runtime.Story story) [0x00000] in <00000000000000000000000000000000>:0 I can see in the generated code that the framework (TTS_Vision) is there, but the path seems wrong. I've tried to add more options to the searched paths, with no success... Any hints or suggestions are much more appreciated.

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