I want to implement the functions in this video, how should I set the window

Spatial widget is a new feature of visionos 26. I notice The system’s Photo app can add a Spatial Image in the widget. I wonder if third apps can use spatial image or any 3D content in it's widget? I try to use RealityView in widget and it run with a crash. So does spatial Image in widget only supported by the system Photo app, and not available to developers now?

Greetings. I am having this issue with a Unity Polyspatial VisionOS app. We have our main Bounded Volume for our app. We have other Native UI windows that appear when we interact with objects in our Bounded Volume. If a user closes our main Bounded Volume...sometimes it quits the app. Sometimes it doesn't. If we go back to the home screen and reopen the app, our main Bounded Volume doesn't always appear, and just the Native UI windows we left open are visible. But, we can sometimes still hear sounds that are playing in our Bounded Volume. What solutions are there to make sure our Bounded Volume always appears when the app is open?

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 this problem on VisionOS. When I dismiss and reopen a window from a ImagePresentationComponent, the window misses the resize ui elements when I look at the window corners. The rest of the window ui elements (drag, close...) are there. Resizing was possible before the window was dismissed. The code is something like this: WindowGroup(id: "image-display-window",..... } .windowResizability(.automatic) .windowStyle(.plain) I call dismissWindow() from the window view and it is dismissed correctly. Then I call openWindow(id: "image-display-window", value: data) from another view to reopen it. It reopens but it missing the possibility to resize. Anyone knows how to fix this? Thanks.

Apple's new Spatial Personas use Gaussian Splatting, but I have not found any APIs for visionOS to display a Gaussian Splat like a PLY file. Am I just missing the Apple documentation? If not, are there common practices developers are using for displaying Gaussian Splats in visionOS?

I have discovered that RemoteImmersiveSpace is limited to utilizing the structure of the CompositorContent protocol, precluding direct invocation of RealityView. Consequently, I am interested in understanding the appropriate method for integrating CompositorContent within RemoteImmersiveSpace. Thanks.

I need to loop my videoMaterial and I don't know how to make it happen in my code. I have included an image of my videoMaterial code. Any help making this happen with be greatly appreciated. Thank you, Christopher

Hi, I have been using RealityRenderer to render scenes in MacOS as spatial videos and view it in Vision Pro and it is awesome. I understand that it uses PerspectiveCamera to render. I wanted to know what is the default FOV for this camera and how much can we push it? I want to ideally render a scene with 180 degrees of fov. Thanks

I am trying to get the new PresentationComponent working in VisionOS26 as seen in this WWDC video: https://aninterestingwebsite.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://aninterestingwebsite.com/documentation/realitykit/presentationcomponent

SpatialEventGesture Not Working to Show Hidden Menu in Immersive Panorama View - visionOS Problem Description I'm developing a Vision Pro app that displays 360° panoramic photos in a full immersive space. I have a floating menu that auto-hides after 5 seconds, and I want users to be able to show the menu again using spatial gestures (particularly pinch gestures) when it's hidden. However, the SpatialEventGesture implementation is not working as expected. The menu doesn't appear when users perform pinch gestures or other spatial interactions in the immersive space. Current Implementation Here's the relevant gesture detection code in my ImmersiveView: import SwiftUI import RealityKit struct ImmersiveView: View { @EnvironmentObject var appModel: AppModel @Environment(\.openWindow) private var openWindow var body: some View { RealityView { content in // RealityView content setup with panoramic sphere... let rootEntity = Entity() content.add(rootEntity) // Load panoramic content here... } // Using SpatialEventGesture to handle multiple spatial gestures .gesture( SpatialEventGesture() .onEnded { eventCollection in // Check menu visibility state if !appModel.isPanoramaMenuVisible { // Iterate through event collection to handle various gestures for event in eventCollection { switch event.kind { case .touch: print("Detected spatial touch gesture, showing menu") showMenuWithGesture() return case .indirectPinch: print("Detected spatial pinch gesture, showing menu") showMenuWithGesture() return case .pointer: print("Detected spatial pointer gesture, showing menu") showMenuWithGesture() return @unknown default: print("Detected unknown spatial gesture: \(event.kind)") showMenuWithGesture() return } } } } ) // Keep long press gesture as backup .simultaneousGesture( LongPressGesture(minimumDuration: 1.5) .onEnded { _ in if !appModel.isPanoramaMenuVisible { print("Detected long press gesture, showing menu") showMenuWithGesture() } } ) } private func showMenuWithGesture() { if !appModel.isPanoramaMenuVisible { appModel.showPanoramaMenu() if !appModel.windowExists(id: "PanoramaMenu") { openWindow(id: "PanoramaMenu", value: "menu") } } } } What I've Tried Multiple SpatialTapGesture approaches: Originally tried using multiple .gesture() modifiers with SpatialTapGesture(count: 1) and SpatialTapGesture(count: 2), but realized they override each other. SpatialEventGesture implementation: Switched to SpatialEventGesture to handle multiple event types (.touch, .indirectPinch, .pointer), but pinch gestures still don't trigger the menu. Added debugging: Console logs show that the gesture callbacks are never called when performing pinch gestures in the immersive space. Backup LongPressGesture: Added a simultaneous long press gesture as backup, which also doesn't work consistently. Expected Behavior When the panorama menu is hidden (after 5-second auto-hide), users should be able to: Perform a pinch gesture (indirect pinch) to show the menu Tap in space to show the menu Use other spatial gestures to show the menu Questions Is SpatialEventGesture the correct approach for detecting gestures in a full immersive RealityView? Are there any special considerations for gesture detection when the RealityView contains a large panoramic sphere that might be intercepting gestures? Should I be using a different gesture approach for visionOS immersive spaces? Is there a way to ensure gestures work even when the RealityView content (panoramic sphere) might be blocking them? Environment Xcode 16.1 visionOS 2.5 Testing on Vision Pro device App uses SwiftUI + RealityKit Any guidance on the proper way to implement spatial gesture detection in visionOS immersive spaces would be greatly appreciated! Additional Context The app manages multiple windows and the gesture detection should work specifically when in the immersive panorama mode with the menu hidden. Thank you for any help or suggestions!

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!

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

In Beta 1,2, and 3, we could pick up and inspect entities, bringing them closer while moving them outside of the bounds of a volume. As of Beta 4, these entities are now clipped by the bounds of the volume. I'm not sure if this is a bug or an intended change, but I files a Feedback report (FB19005083). The release notes don't mention a change in behavior–at least not that I can find. Is this an intentional change or a bug? Here is a video that shows the issue. https://youtu.be/ajBAaSxLL2Y In the previous versions of visionOS 26, I could move these entities out of the volume and inspect them close up. Releasing would return them to the volume. Now they are clipped as soon as they reach the end of the volume. I haven't had a chance to test with windows or with the SwiftUI modifier version of manipulation.

I’ve been having some issues removing anchors. I can add anchors with no issue. They will be there the next time I run the scene. I can also get updates when ARKit sends them. I can remove anchors, but not all the time. The method I’m using is to call removeAnchor() on the data provider. worldTracking.removeAnchor(forID: uuid) // Yes, I have also tried `removeAnchor(_ worldAnchor: WorldAnchor)` This works if there are more than one anchor in a scene. When I’m down to one remaining anchor, I can remove it. It seems to succeed (does not raise an error) but the next time I run the scene the removed anchor is back. This only happens when there is only one remaining anchor. do { // This always run, but it doesn't seem to "save" the removal when there is only one anchor left. try await worldTracking.removeAnchor(forID: uuid) } catch { // I have never seen this block fire! print("Failed to remove world anchor \(uuid) with error: \(error).") } I posted a video on my website if you want to see it happening. https://stepinto.vision/labs/lab-051-issues-with-world-tracking/ Here is the full code. Can you see if I’m doing something wrong? Is this a bug? struct Lab051: View { @State var session = ARKitSession() @State var worldTracking = WorldTrackingProvider() @State var worldAnchorEntities: [UUID: Entity] = [:] @State var placement = Entity() @State var subject : ModelEntity = { let subject = ModelEntity( mesh: .generateSphere(radius: 0.06), materials: [SimpleMaterial(color: .stepRed, isMetallic: false)]) subject.setPosition([0, 0, 0], relativeTo: nil) let collision = CollisionComponent(shapes: [.generateSphere(radius: 0.06)]) let input = InputTargetComponent() subject.components.set([collision, input]) return subject }() var body: some View { RealityView { content in guard let scene = try? await Entity(named: "WorldTracking", in: realityKitContentBundle) else { return } content.add(scene) if let placementEntity = scene.findEntity(named: "PlacementPreview") { placement = placementEntity } } update: { content in for (_, entity) in worldAnchorEntities { if !content.entities.contains(entity) { content.add(entity) } } } .modifier(DragGestureImproved()) .gesture(tapGesture) .task { try! await setupAndRunWorldTracking() } } var tapGesture: some Gesture { TapGesture() .targetedToAnyEntity() .onEnded { value in if value.entity.name == "PlacementPreview" { // If we tapped the placement preview cube, create an anchor Task { let anchor = WorldAnchor(originFromAnchorTransform: value.entity.transformMatrix(relativeTo: nil)) try await worldTracking.addAnchor(anchor) } } else { Task { // Get the UUID we stored on the entity let uuid = UUID(uuidString: value.entity.name) ?? UUID() do { try await worldTracking.removeAnchor(forID: uuid) } catch { print("Failed to remove world anchor \(uuid) with error: \(error).") } } } } } func setupAndRunWorldTracking() async throws { if WorldTrackingProvider.isSupported { do { try await session.run([worldTracking]) for await update in worldTracking.anchorUpdates { switch update.event { case .added: let subjectClone = subject.clone(recursive: true) subjectClone.isEnabled = true subjectClone.name = update.anchor.id.uuidString subjectClone.transform = Transform(matrix: update.anchor.originFromAnchorTransform) worldAnchorEntities[update.anchor.id] = subjectClone print("🟢 Anchor added \(update.anchor.id)") case .updated: guard let entity = worldAnchorEntities[update.anchor.id] else { print("No entity found to update for anchor \(update.anchor.id)") return } entity.transform = Transform(matrix: update.anchor.originFromAnchorTransform) print("🔵 Anchor updated \(update.anchor.id)") case .removed: worldAnchorEntities[update.anchor.id]?.removeFromParent() worldAnchorEntities.removeValue(forKey: update.anchor.id) print("🔴 Anchor removed \(update.anchor.id)") if let remainingAnchors = await worldTracking.allAnchors { print("Remaining Anchors: \(remainingAnchors.count)") } } } } catch { print("ARKit session error \(error)") } } } }

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

I saw at WWDC25 mentions of visionOS 26 now providing hand tracking poses at 90hz, but I also recall that being a feature in visionOS 2. Is there something new happening in visionOS 26 that makes its implementation of hand tracking "better"?

The following sample code project does not seem to work as expected: https://aninterestingwebsite.com/documentation/visionos/implementing-shareplay-for-immersive-spaces-in-visionos Have tried to get this project working with a client, but while we were able to see nearby users and make facetime calls, the color changing cube experience always remained a single color. Are there step-by-step instructions that Apple has used to verify this sample code so I can try to recreate this sample code's expected behavior for both nearby participants and those in a Facetime call?

Posting this here in case this information is helpful to other developers: As of visionOS 26.3 beta 1, onWorldRecenter has two significant issues: (FB21557639) Memory Leak: When onWorldRecenter is assigned to a RealityView within an ImmersiveSpace, it appears to retain a strong reference to the view's internal SwiftUI context. When the immersive space is dismissed, the view's @State objects will not be deallocated. Also, each time the immersive space view's body is executed, additional state storage will be allocated and leaked. Multiple Callbacks: When the user long-presses the Digital Crown, the onWorldRecenter closure will be called multiple times, once for each past view body execution, including those of immersive space views that have been previously dismissed. Although these issues seem to be most prevalent when onWorldRecenter is used with an ImmersiveSpace, they may also occur in the context of a WindowGroup under certain circumstances. It's possible to work around this problem by moving onWorldRecenter to an empty overlay view within the app's primary WindowGroup and forwarding the world recenter events to ImmersiveSpace views through a notification system, coupled with a debouncer as an extra precaution.
