I would like to translate info in a three.js based web app as a 3D model in a volumetric window. Is it possible to do this in a similar manner as loading a web page in a WKWebView?

I am trying to get the new PresentationComponent working in VisionOS26 as seen in this WWDC video: https://developer.apple.com/videos/play/wwdc2025/274/?time=962 (18:29 minutes into video) Here is some other example code but it doesn't work either: https://stepinto.vision/devlogs/project-graveyard-devlog-002/ My simple Text view (that I am adding as a PresentationComponent) does not appear in my RealityView even though the entity is found. Here is a simple example built from an Xcode immersive view default project: struct ImmersiveView: View { @Environment(AppModel.self) var appModel 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) if let materializedImmersiveContentEntity = try? await Entity(named: "Test", in: realityKitContentBundle) { content.add(materializedImmersiveContentEntity) var presentation = PresentationComponent( configuration: .popover(arrowEdge: .bottom), content: Text("Hello, World!") .foregroundColor(.red) ) presentation.isPresented = true materializedImmersiveContentEntity.components.set(presentation) } } } } } Here is the Apple reference: https://developer.apple.com/documentation/realitykit/presentationcomponent

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

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?

Is there a suitable UTType type to satisfy the need to pick up only SpatialVideo in UIDocumentPickerViewController? I already know that PHPickerFilter in PHPickerViewController can do this, but not in UIDocumentPickerViewController. Our app needs to adapt both of these ways to pick spatial videos So is there anything that I can try in UIDocumentPickerViewController to fulfill such picker functionality?

This modifier in visionOS 2.5 works perfectly with LazyVgrid inside a Stack in ScrollView: .hoverEffect { effect, isActive, _ in effect.scaleEffect(isActive ? 1.1 : 1.0) But the grid does not scroll in visionOS 26 beta 1 unless the scaleEffect is commented out. FB17941468

Since using Quick Look exits you from both your app and Immersive Space. Is there a way to view immersive images within Immersive Space?

Hi everyone, I've been exploring an idea that involves using virtual light sources in VisionOS/RealityKit to interact with real-world objects. Specifically, I'd like to simulate a scenario where a virtual spotlight or other light source casts light or shadows onto real-world environments, creating the effect of virtual lighting interacting with physical surroundings. Is this currently feasible within VisionOS/RealityKit? Thank you!

This might be a very silly question, anyway I tried many ways and didn't find a solution: My Mac mini M4 is basic version which only has 16GB memory, it is very shy for developing Vision Pro application and testing with the simulator (CleanMacX always warning me low memory), I want to debug and test the application directly on Vision Pro (+ my app need both two hands gestures which simulator might not support) in stead of simulator, is there any proper instructions on how I test/debug/run the App on VP device directly instead of on simulator in favor of speed?

Is it possible to create a button in my app that will turn on the spatial personas for the user? Currently the only way I know of turning on spatial personas is by selecting the cube icon in the FaceTime window which is quite clunky for people unfamiliar with the Vision Pro's UI. Any help would be appreciated.

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.

In the particle effect of RealityKit, there is a Type: ParticleEmitterComponent.Presets He can invoke certain particle effects in certain systems, but I am interested in learning how to modify these particle entities (such as adjusting the color, the number of particles, the generation range…)?

Hi team I don't know from this error has popped up any suggestions please Thanks Zippy Games

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!

Entity.animate() makes entity animation much easier, but in many cases, I want to break the progress because of some gestures, I couldn't find any way to do this, including tried entity.stopAllAnimations(), I have to wait till Entity.animate() completes. iOS 26 / visionOS 26

Can I combine FromToByAction and BindTarget.MaterialPath to animate my ShaderGraphMaterial. I don't know how to use the BindTarget.MaterialPath.

One of the most common ways to provide a window size in visionOS is to use the defaultSize scene modifier. WindowGroup(id: "someID") { SomeView() } .defaultSize(CGSize(width: 600, height: 600)) Starting in visionOS 26, using this has a side effect. visionOS 26 will restore windows that have been locked in place or snapped to surfaces. If a user has manually adjusted the size of a locked/snapped window, the users size is only restore in some cases. Manual resize respected Leaving a room and returning later Taking the headset off and putting it back on later Manual resize NOT respected Device restart. In this case, the window is reopened where it was locked, but the size is set back to the values passed to defaultSize. The manual resizing adjustments the user has made are lost. This is counter to how all other windows and widgets work. I reported this last month (FB18429638), but haven't heard back if this is a bug or intended behavior. Questions What is the best way to provide a default window size that will only be used when opening new windows–and not used during scene restoration? Should we try to keep track of window size after users adjust them and save that somewhere? If this is intended behavior, can someone please update the docs accordingly?

Following up on my previous question here: https://developer.apple.com/forums/thread/774262 Having solved the clipping problem, I am now trying to overlay some content in front of the RealityView. However, it looks like any content with transparency does not render in front of the RealityView, while opaque views seem to work; placing content with transparency like glassBackgroundEffect() behind the RealityView in a ZStack causes the entire window to flicker. Additionally, my SwiftUI attachment placed in front of the stereoscopic image plane are invisible if the user look at it straight at 90 degrees. However, if the user look at it from increasing angles from the sides, the attachment gradually turns visible again. Are these behaviors expected? What is a recommended approach to overlay content in front of a RealityView? Thanks!

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?

Hello! I’m excited to see that Look to Scroll has been included in visionOS 26 Beta. I’m aiming to achieve a feature where the user’s gaze at a specific edge automatically scrolls to that position. However, I’ve experimented with ScrollView and haven’t been able to trigger this functionality. Could you advise if additional API modifiers are necessary? Thank you!
