I've encountered an unexpected crash with RoomPlan on iOS 16 devices. The odd part is the code is protected by an available check, since I'm using newer RoomPlan features. Xcode error dyld[40588]: Symbol not found: _$s8RoomPlan08CapturedA0V16USDExportOptionsV5modelAEvgZ I can repro using the Apple sample code. https://developer.apple.com/documentation/roomplan/create-a-3d-model-of-an-interior-room-by-guiding-the-user-through-an-ar-experience Modify RoomCaptureViewController.swift as follows. Remove try finalResults?.export(to: destinationURL, exportOptions: .parametric) Add if #available(iOS 17.0, *) { try finalResults?.export(to: destinationURL, exportOptions: .model) } else { try finalResults?.export(to: destinationURL, exportOptions: .parametric) } I would have expected this code to at least compile and run on older devices. When the app was targeting iOS 15, the available checks worked as expected and the app is able to launch properly.

For the M2 Apple Vision Pro, there's "a general guideline, we recommend no more than 500 thousand triangles for an immersive scene, with 250 thousand for applications in the shared space." --https://developer.apple.com/videos/play/wwdc2024/10186/?time=147 Is there a revised recommendation for the M5 Apple Vision Pro?

Hi Apple Team, We noticed the following exciting changelog in the latest macOS 26 beta: A new algorithm significantly improves PhotogrammetrySession reconstruction quality of low-texture objects not captured with the ObjectCaptureSession front end. It will be downloaded and cached once in the background when the PhotogrammetrySession is used at runtime. If network isn’t available at that time, the old low quality model will be used until the new one can be downloaded. There is no code change needed to get this improved model. (145220451) However after trying this on the latest beta and running some tests we do not see any differences on objects with low textures such as single coloured surfaces. Is there anything we are missing? the machine is definitely connected to the internet but we have no way of knowing from the logs if the new model is being used? thanks

Hi, Few days ago, Apple had another "Meet with Apple" event regarding immersive video : Create immersive media experiences for visionOS | Meet with Apple days one and 2 and it is not appearing on my Developer app in Mac. The same happened to IETF HLS Interest Day | Meet with Apple. Any tip? Kind regards , Bruno

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!

Summary After updating to visionOS 26, we’ve encountered severe transparency rendering issues in RealityKit that did not exist in visionOS 2.6 and earlier. These regressions affect applications that dynamically control scene opacity (via OpacityComponent). Our app renders ultra-realistic apartment environments in real time, where users can walk or teleport inside 3D spaces. When the user moves above a speed threshold, we apply a global transparency effect to prevent physical collisions with real-world objects. Everything worked perfectly in visionOS 2.6 — the problems appeared only after upgrading to 26. Scene Setup Overview The environment consists of multiple USDZ models (e.g., architecture, rooms, furniture). We manage LODs manually for performance (e.g., walls and floors always visible in full-res, while rooms swap between low/high-res versions based on user position and field of view). Transparency is achieved using OpacityComponent, applied dynamically when the user moves. Some meshes (e.g., portals to skyboxes, glass windows) use alpha materials We also use OcclusionMaterials to prevent things to be seen through walls when scene is transparent Observed Behavior by Scenario (I can share a video showing the results of each scenario if needed.) Scenario 1 — Severe Flickering (Root Opacity) Setup: OpacityComponent applied to the root entity NO ModelSortGroupComponent used Symptoms: Strong flickering when transparency is active Triangles within the same mesh render at inconsistent opacity levels Appears as if per-triangle alpha sorting is broken Workaround: Moving the OpacityComponent from the root to each individual USDZ entity removes the per-triangle flicker Pros: No conflicts with portals or alpha materials Scenario 2 — Partially Stable, But Alpha Conflicts Setup: OpacityComponent applied per USDZ entity ModelSortGroupComponent(planarUIAlwaysBehind) applied to portal meshes Other entities have NO ModelSortGroupComponent Symptoms: Frequent alpha blending conflicts: Transparent surfaces behind other transparent surfaces flicker or disappear Example: Wine glasses behind glass doors — sometimes neither is rendered, or only one Even opaque meshes behind glass flicker due to depth buffer confusion Alpha materials sometimes render portals or the real world behind them, ignoring other geometry entirely Analysis: Appears related to internal changes in alpha sorting or depth pre-pass behavior introduced in visionOS 26 Pros: Most stable setup so far Cons: Still unreliable when OpacityComponent is active Scenario 3 — Layer Separation Attempt (Regression) Setup: Same as Scenario 2, but: Entities with alpha materials moved to separate USDZs Explicit ModelSortGroupComponent order set (alpha surfaces rendered last) Symptoms: Transparent surfaces behind other transparent surfaces flicker or disappear Depth is completely broken when there's a large transparent surface Alpha materials sometimes render portals or the real world behind them, ignoring other geometry entirely Workaround Attempt: Re-ordering and further separating models did not solve it Pros: None — this setup makes transparency unusable Conclusion There appears to be a regression in RealityKit’s handling of transparency and sorting in visionOS 26, particularly when: OpacityComponent is applied dynamically, and Scenes rely on multiple overlapping transparent materials. These issues did not exist prior to 26, and the same project (no code changes) behaves correctly on previous versions. Request We’d appreciate any insight or confirmation from Apple engineers regarding: Whether alpha sorting or opacity blending behavior changed in visionOS 26 If there are new recommended practices for combining OpacityComponent with transparent materials If a bug report already exists for this regression Thanks in advance!

Is there any size guidance for the new WidgetKit integration on visionOS? The Widget HIG provides dimensions for all the widget size classes on iOS, iPadOS and watchOS, but has not been updated for visionOS. https://developer.apple.com/design/human-interface-guidelines/widgets My potential widget use case is image based, so I'm looking to better understand the optimal size, resolution etc I would need, particularly for the new visionOS specific extra large widget size.

Apple's WWDC video What’s new for the spatial web says the spatial-backdrop markup may change as it goes through the standards process (at 27:26 mark). I have started adding spatial-backdrops to web pages, so I want to keep an eye out for status updates by Apple and follow the standards progress. Is there any place I can keep an eye on this standards process? Has Apple announced any feature updates or news on spatial-backdrops?

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 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.

Hello again! So, I am trying my best to figure out how to get a simple, fully Immersive scene that is navigable via the PS5 controller to work on Vision Pro. I am even using ChatGPT (both externally AND in Xcode when it makes fix recommendations) however, I seem to be moving around in circles, having to constantly send error messages back to ChatGPT, then try the new "confirmed to work" fixed code, only to have more errors. I also have explicitly let the AI know that I'm using all the current betas, only to learn there has been lots of stuff deprecated (of course!). This is my initial query to ChatGPT: "How can I create a fully immersive VR experience for Apple Vision Pro, using a PS5 game controller to navigate the user via first person view through a 3d scene?" And then down the rabbit hole the past few days. Seriously, I thought AI was supposed to be helpful! LOL Per Xcode logs, I'm seeing thumbstick movement, but simply cannot get the camera to move. Is this even possible?! Is it a camera defined in Reality Composer Pro? Or, does it need to be defined outside. I'm trying to follow along with the AI, but it seems to go back and forth with different solutions. Here is the latest it's spitting out: __ Thanks for this super clear log — and you’re absolutely right: the gamepad input is working, CameraRoot is moving as expected… but your actual camera view is not changing. This strongly suggests the issue is that RealityKit is not using your custom camera (PerspectiveCameraComponent) for rendering the view. ⸻ 🔍 What’s happening Even though CameraRoot is moving (with correct logs), RealityKit will default to its own internal camera unless: 1. You explicitly assign your camera entity to be the one used, or 2. Your camera is the only one and RealityKit picks it up automatically. But in visionOS 2.0 / Xcode 26, there seems to be a bug or behavior change where RealityKit no longer auto-uses your custom PerspectiveCameraComponent in RealityView unless it’s: • properly set with content.camera, or • part of a .usda/Reality Composer camera hierarchy that’s already active. Unfortunately: 🟥 RealityView.camera = .entity(cameraRoot) ❌ Is no longer allowed (we confirmed this breaks with a type error) ⸻ ✅ The Reliable Workaround: Attach your camera to the Immersive scene itself Since we’re loading a .usda scene (Reality Composer Pro), here’s the most reliable path forward: ✔️ Option A: Embed your camera into the Reality Composer Pro scene 1. Open your Reality Composer Pro scene 2. Add a Camera entity directly in your Immersive.usda scene 3. Name it something like "PlayerCamera" 4. Position it at [0, 1.6, 0] 5. Leave it selected as the default camera Then in your Swift code: • Find the camera entity with .findEntity(named:) • Move that entity instead of creating a new one. ⸻ ✔️ Option B: Force RealityKit to use your custom camera (via transform parenting) Since direct camera assignment is unavailable, we can use a trick: Move the whole RealityView scene via a parent entity with a camera. But let’s go with Option A, since you’ve already got a Reality Composer Pro scene. __ Can any developer over there can make a suggestion on how to move forward? I JUST want to create a sandbox template so I can start exploring 3d scenes created in Maya and sent over to headset. I'll deal with animation next, but come on, why is this so difficult to get working? I'm not a programmer, but have been trying to wrap my head around Xcode and SwiftUI. This needs to be much simpler. Or, you need to provide us creatives with better sample templates and non programmer speak on how to set this up properly. Ideally, you HIRE us 3d professionals to work side by side with the programmers to help make these tools useable - especially Reality Composer Pro. Seriously, I am making a concerted effort to use the native tools, even though I would love to be porting Unreal Engine scenes over. If anyone can help point me in the right direction, coming from a 3D Creator/Animator/Modeler perspective, I, and my fellow peers in the XR/AR/VR community would greatly appreciate it. Thank you.

We're trying to switch from using main camera access on Arkit to screen-capture with passthrough however we're facing some issues and it seems a bit complicated to debug. We have set up a broadcast Extension, set up some logs on the sample Handler but we get nothing in the console nor that the recording starts, we set up the picker as well and we can see our extension in the control center as one of the choices but clicking start, results in it stopping in less than one second after. The only message that is rather contradictory we see in the console.app is the following [INFO] -[RPRecordingManager getSystemBroadcastExtensionInfo:]_block_invoke:1333 Extension has passthrough license and just right after [INFO] -[RPRecordingManager getSystemBroadcastExtensionInfo:]_block_invoke:1336 Extension does not have passthrough license

With Xcode 26, loading ressources with RealityKit is extremely slow. Here my project takes almost 50 seconds to load. I also get multiple Hang detected messages in the console: When I uncheck "Debug executable" in the schema, the same project loads in 2 seconds. I'm using RealityKit asynchronous loading: private static func loadFromRealityComposerPro( named entityName: String, fromSceneNamed sceneName: String ) async -> Entity? { var entity: Entity? do { let scene = try await Entity( named: sceneName, in: visionPetsContentBundle ) entity = scene.findEntity(named: entityName) } catch { print( "Error loading \(entityName) from scene \(sceneName): \(error.localizedDescription)" ) } return entity } Anyone having the same problem?

I posted https://developer.apple.com/forums/thread/809481 yesterday about an issue I discovered with pushWindow in visionOS 26.2 RC, but today I discovered a second problem with pushWindow. If window A calls pushWindow to present window B, and the user pins window B to a wall, the following unexpected behaviors are observed: Window B spontaneously disappears. If the user re-launches the (still running) app from the visionOS home view, both window A and window B appear simultaneously. I assume only window B should be visible at this point, since window A pushed window B. If the user closes window B, it's now impossible to present window B again. Calls to pushWindow appear to be ignored. If the user force-quits the app and relaunches it, and pushWindow is called again, window B appears, but window A remains visible. I also noticed this surprising behavior: This broken state of pushWindow behavior now affects all other apps on the system that may call pushWindow in the future, not just the app whose pushed window was pinned above. A workaround is to reboot the device, and then the system will behave as expected until the next time the user pins a pushed window.

Has Roomplan been abandoned? Two years have gone by without comments from Apple on improvements. Are the improvements behind the scenes? Is there going to be any major updates?

Hello, I'm adding a CollisionComponent to an entity in RealityView. CollisionComponent requires that a Mesh must be provided as a reference for collision detection. However, in order to achieve more accurate detection, I hope that this Mesh resource is a geometric shape of a USDZ model. Is there any way to make it happen? Thank you!

I have been experimenting with the Hello World sample app from https://developer.apple.com/documentation/visionos/world and I came across behavior that appears inconsistent with user-facing documentation describing the device controls at https://support.apple.com/en-gb/guide/apple-vision-pro/tan1e2a29e00/visionos I tried pressing simulator's "Home" button while "Objects in Orbit" immersive space was presented alongside with the main application window. According to user documentation, pressing Digital Crown should take the user directly to Home View. In my test a single press only dismissed the immersive space, I needed another press to "exit" the app and go to Home View. Is this behavior expected? I am assuming that "Home" button in the simulator behaves as if the user pressed Digital Crown on the device, I don't have access to the actual hardware.

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?

.glassEffect(.regular, in: .rect(cornerRadius: 24)) error; 'glassEffect(_:in:isEnabled:)' is unavailable in visionOS This is not surprising since visionOS already has a native glass interface that formed a model for the other OS's, but this error will create additional overhead for developers creating multi-platform apps that include visionOS.

I would like to visualize a point cloud taken from a lidar. Assuming I can get the XYZ values of every point (of which there may be hundreds or thousands), what is the most efficient way for me to create a point cloud using this information?
