In Vision OS app, We have two types of windows: Main App Window – This is the default window that launches when the app starts. It displays the video listings and other primary content. Immersive Space Window – This opens only when a user starts streaming or playing a video. Issue: When entering the immersive space, the main app window remains visible in front of it unless manually closed. To avoid this, I currently close the main window when transitioning to immersive space and reopen it when exiting. However, this causes the app to restart instead of resuming from its previous state. Desired Behavior: I want the main app window to retain its state and seamlessly resume from where it was before entering immersive mode, rather than restarting. Attempts & Challenges: Tried managing opacity, visibility, and state preservation, but none worked as expected. Couldn’t find a way to push the main window to the background while bringing the immersive space to the foreground. Looking for a solution to keep the main window’s state intact while transitioning between immersive and normal modes.

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:

How can I guide users to set their preferred language in visionOS? At this point, the behavior seems to be different from that of iOS.

hi guys, I'm working in VFX industry and I've got the question that, is it possible to create immersive video directly from virtual scene created in DCC software like maya, rendered into footage, then coded into immersive video, and finally play in in vision pro? thanks.

For visionOS 2.0+, it has been announced the object tracking feature. Is there any support for PolySpatial in Unity or is it only available in Swift and Xcode?

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).

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 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.

I implemented a ShaderGraphMaterial and tried to load it from my usda scene by ShaderGraphMaterial.init(name: in: bundle). I want to dynamically set TextureResource on that material, so I wanted to expose texture as Uniform Input of a ShaderGraphMaterial. But obviously RCP's Shader Graph doesn't support Texture input as parameter as the image shows: And from the code level, ShaderGraphMaterial also didn't expose a way to set TexturesResources neither. Its parameterNames shows an empty array if I didn't set any custom input params. The texture I get is from my backend so it really cannot be saved into a file and load it again (that would be too weird). Is there something I am missing?

I have been trying to implement this look where a component looks "pushed in" but I could not find any resources regarding this effect. The closest I got was a combination of a RoundedRectangle and .glassBackgroundEffect(), but this makes the view look pushed out, instead of pushed in. I was wondering if this is achievable in SwiftUI level, or even in UIKit level.

In visionOS, there are existing modifiers that can completely conceal the hands. However, I am interested in learning how to achieve the effect of only one hand disappearing while the other hand remains visible. .upperLimbVisibility(.hidden)

I like the toolbar visionOS's Safari uses for back & forward page, share, etc. It floats above the window. My attempt to do this with ornaments isn't as satisfying as they partially cover the window. My attempts with toolbar haven't produced visible results. Is this Safari-style toolbar for visionOS exposed by Apple in the API's? If so, could someone point me to documentation or sample code? 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.

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

While using Screen Mirroring in developer mode within my immersive space, I noticed an alignment issue with the computer cursor (transparent circle). When I move it toward an attachment view, the cursor remains horizontal instead of aligning with the surface of the attachment view. It shows correctly on a 2D window only wrong on attachment view. Is this behavior a bug, or could it be caused by a missing or incorrect configuration on the attachment view? Want help, thanks.

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

I have a class with an Entity, on which I added a Spatial Audio component. Furthermore, I have a function, which uses the playAudio() method to start the Spatial Audio. During the first call of the function, everything is fine. If I call the again, the audio volume drops abruptly after a half second. It is very quiet. Approximately, I have following code: class VoiceOutputPlayer: NSObject, ObservableObject, AVAudioPlayerDelegate { private var speechEntity = Entity() func play() { Task{ let audioRessource = try await AudioFileResource(contentsOf: urlWave) self.speechEntity.playAudio(audioRessource) } } func initSpatialAudio() -> Entity { speechEntity.transform.translation.y = -0.37 speechEntity.transform.translation.z = 0.09 speechEntity.spatialAudio = SpatialAudioComponent(gain: Double.zero) speechEntity.spatialAudio?.reverbLevel = -2 speechEntity.spatialAudio?.directivity = .beam(focus: 0.9) speechEntity.orientation = .init(angle: .pi, axis: [0, 1, 0]) speechEntity.spatialAudio?.distanceAttenuation = .rolloff(factor: 1) return speechEntity } } Have visionOS 2.2 on the Apple Vision Pro and use Xcode 16.1

I have a huge sphere where the camera stays inside the sphere and turn on front face culling on my ShaderGraphMaterial applied on that sphere, so that I can place other 3D stuff inside. However when it comes to attachment, the object occlusion never works as I am expecting. Specifically my attachments are occluded by my sphere (some are not so the behavior is not deterministic. Then I suspect it was the issue of depth testing so I started using ModelSortGroup to reorder the rending sequence. However it doesn't work. As I was searching through the internet, this post's comments shows that ModelSortGroup simply doesn't work on attachments. So I wonder how should I tackle this issue now? To let my attachments appear inside my sphere. OS/Sys: VisionOS 2.3/XCode 16.3

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.
