For context, we have a fully immersive application running on visions. The application starts with a standard View/menu, and when the user clicks an option, it takes you to fully immersive mode with a small floating toolbar window that you can move and interact with as you move around the virtual space. When the user clicks the small x button below the window, we intercept the scenePhase .background event and handle exiting immersive mode and displaying the main menu. This all works fine. The problem happens if the user turns around and doesn't look at the floating window for a couple of minutes. The system decides that the window should go into the background, and the same scenePhase background event is called - causing the system to exit immersive mode without warning. There seems to be no way of preventing this, and no distinction between this and the user clicking the close button. Is there a reliable way to detect if the user intentionally clicks the close button vs the window from going into the background through lack of use? onDisappear doesn't trigger. thanks in advance

I'm having issue with loading 1.2GB USDZ file with visionOS Here's the details the file is download via backend api file is download to document directory FileManager.default.url(for: .documentDirectory, in: .userDomainMask, appropriateFor: nil, create: true) when loading the asset, it took almost 30s to load the asset Loaded usd((extension in RealityFoundation):RealityKit.Entity.LoadStatistics.USDLoader.rio) in 29.24642503261566 seconds loading asset code let model = try await Entity(contentsOf: assetUrl) USDZ file is exported from RealityComposerPro Did I make any mistake on the flow or is there any other approach to decrease the loading time?

I would like to know if I can simply show a spatial image on the app without having to open a "preview" The photos would be spatial photos (HEIC files) converted using Vision Pro.

Hello I've just updated my Vision Pro to the newest and greatest 2.0, and I see that the way to call out control center has been changed to the hand gesture which I'm assuming that is powered by computer vision? using the cams, for me there is a use case of watching apple TV shows at night where my gf would like to have the lights turned off, and that is the time where it fails, the new method is greate and the responsiveness are crazily good, but I would like this to be a toggle so that we can select our own method? like for example during the day where lights are sufficient we use the new gestrue recogn way, and when low light we can switch it back to look up? or as a fellow programmer who are just learning, I think it is possible to just make it automatic toggle, whenever the lighting condition can't make the hand gestrue work, hope to see that fixed :) cheers

I have an immersive space that is rendered using metal. Is there a way that I can position swiftUI views at coordinates relative to positions in my immersive space? I know that I can display a volume with RealityKit content simultaneously to my metal content. The volume's coordinate system specifically, it's bounds, does not, coincide with my entire metal scene. One approach I thought of would be to open two views in my immersive space. That way, I could simply add Attachment's to invisible RealityKit Entities in one view at positions where I have content in my metal scene. unfortunately it seems that, while I can declare an ImmersiveSpace be composed of multiple RealityViews ImmersiveSpace(){ RealityView { content in // load first view } update: { content in // update } } RealityView{ content in //load second view } } update: { content in //update } } That results in two coinciding realty kit views in the immersive space. I can not however do something like this: ImmersiveSpace(){ CompositorLayer(configuration: ContentStageConfiguration()){ layerRenderer in //set up my metal renderer and stuff } RealityView{ content in //set up a view where I could use attachments } update: { content in } }

I am having problems getting button input from an Xbox game controller. I have the visionOS 2 beta on my Apple Vision Pro, and I am trying to use an Xbox game controller with a RealityView following the instructions from the WWDC session Explore game input in visionOS. The notification about a game controller is picking up the game controller, finds GCInputButtonA, and I am setting closures for touchedChangedHandler, pressedChangedHandler, and valueChangedHandler that just print an os_log statement. buttonA.valueChangedHandler = { button, value, pressed in os_log("Got valueChangedHandler") } At the end of RealityView, I have the modifier RealityView { content in // stuff } .handlesGameControllerEvents(matching: .gamepad) But I am never seeing the log message appear in the console when I press the 'A' button (or any other button). Any ideas what I might be doing wrong? The Xbox controller is pretty old. Settings is reporting it as version 9.0.3

Does anyone have code for realistic shaders for the Sun and Earth for a cosmology app in visionOS? Thanks

Hi everyone, I'm working on a Vision Pro application and encountering an issue while trying to load a USDZ file. Here are the details: File Path: /Users/siddharthpatel/Library/Developer/CoreSimulator/Devices/31F10013-50B6-4CEF-9388-9094087FAEBF/data/Containers/Data/Application/EB260F0A-A84F-4E95-876D-08199D2A4998/Documents/hive1.usdz Code: do { try await modelEntityForCollider = ModelEntity(contentsOf: fileURL!) } catch { print("Error loading model: (error)") } Error: Thread 1: Fatal error: Failed to import entity from "/Users/siddharthpatel/Library/Developer/CoreSimulator/Devices/31F10013-50B6-4CEF-9388-9094087FAEBF/data/Containers/Data/ ... ve1.usdz" I've verified that the file path is correct and the USDZ file exists at the specified location. What could be causing this error and how can I resolve it? Thanks in advance for your help! Siddharth

I learned Sharplay from the WWDC video. I understand the creation of seats, but I can't learn some of the following contents well, so I hope you can help me. The content is as follows: I have set up the seats. struct TeamSelectionTemplate: SpatialTemplate { let elements: [any SpatialTemplateElement] = [ .seat(position: .app.offsetBy(x: 0, z: 4)), .seat(position: .app.offsetBy(x: 1, z: 4)), .seat(position: .app.offsetBy(x: -1, z: 4)), .seat(position: .app.offsetBy(x: 2, z: 4)), .seat(position: .app.offsetBy(x: -2, z: 4)), ] } It was mentioned in one of my previous posts: "I hope you can give me a SharePlay Button. After pressing it, it will assign all users in Facetime to a seat with elements quantified in TeamSe lectionTemplate.", and someone replied to me and asked me to try systemCoordinator.configuration.spatialTemplatePreference = .custom (TeamSelectionTemplate()), however, Xcode error Cannot find 'systemCoordinator' in scope How to solve it? Thank you!

Hello, We are wondering how and if we can save/render the view that a PerspectiveCamera sees in VisionOS. Ideally, the goal is to use a PerspectiveCamera in a Mixed Immersive space and render out what it sees. We don't see any methods exposed for rendering the view. We would truly appreciate any advice on this! Thank you.

Hello everyone! I'm planning to buy an Apple Vision Pro (for replacing a Varjo XR-3) I want to use it for a professional project, and I want to know if it can fit our need. I want to develop a program on the Vision Pro for playing some live streaming videos from our local network cameras. (using RTSP) Is this possible to get and play more than one live stream video. One of those videos come from a stereo camera, streaming a SideBySide 3d stereo video. Is this possible to have a classic 2d video in one ultra-wide virtual screen and another one virtual screen displaying a 3D video with depth simultaneously? Thank you everyone in advance. Regard's.

I found that the app AirDraw can export users' draw scenes to a USDZ file. So how can I implement this function using RealityKit?

I am trying to make the immersive version of AVplayerViewController bigger, but I can't find any information on how I can go about it. It seems that if I wanted to change immersive video viewing experience, only thing I can do is using VideoMaterial and put it on ModelEntity with .generatePlane. is there a way to change video size on immersive mode for AVplayerViewController?

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?

Is there a way to provide CLHeading in visionOS so I can more accurately understand the direction in which a user is facing?

Hello, I am new to swiftUI and VisionOS but I developed an app with a window and an ImmersiveSpace. I want the Immersive space to be dismissed when the window/app is closed. I have the code below using the state of ScenePhase and it was working fine in Vision OS 1.1 but it stopped working with VisionOS 2.0. Any idea what I am doing wrong? Is there another way to handle the dismissal of ImmersiveSpace when my main Window is closed? @main struct MyApp: App { @State private var viewModel = ViewModel() var body: some Scene { @Environment(\.scenePhase) var scenePhase @Environment(\.dismissImmersiveSpace) var dismissImmersiveSpace WindowGroup { SideBarView() .environment(viewModel) .frame(width: 1150,height: 700) .onChange(of: scenePhase, { oldValue, newValue in if newValue == .inactive || newValue == .background { Task { await dismissImmersiveSpace() viewModel.immersiveSpaceIsShown = false } } }) }.windowResizability(.contentSize) ImmersiveSpace(id: "ImmersiveSpace") { ImmersiveView(area: viewModel.currentModel) .environment(viewModel) } } }

Hello, I am currently developing an application using RealityKit and I've encountered a couple of challenges that I need assistance with: Capturing Perspective Camera View: I am trying to render or capture the view from a PerspectiveCamera in RealityKit/RealityView. My goal is to save this view of a 3D model as an image or video using a virtual camera. However, I'm unsure how to access or redirect the rendered output from a PerspectiveCamera within RealityKit. Is there an existing API or a recommended approach to achieve this? Integrating SceneKit with RealityKit: I've also experimented with using SCNNode and SCNCamera to capture the camera's view, but I'm wondering if SceneKit is directly compatible within a RealityKit scene, specifically within a RealityView. I would like to leverage the advanced features of RealityKit for managing 3D models. Is saving the virtual view of a camera supported, and if so, what are the best practices? Any guidance, sample code, or references to documentation would be greatly appreciated. Thank you in advance for your help!

I just follow the video and add the codes, but when I switch to spatial video capturing, the videoPreviewLayer shows black. <<<< FigCaptureSessionRemote >>>> Fig assert: "! storage->connectionDied" at bail (FigCaptureSessionRemote.m:405) - (err=0) <<<< FigCaptureSessionRemote >>>> captureSessionRemote_getObjectID signalled err=-16405 (kFigCaptureSessionError_ServerConnectionDied) (Server connection was lost) at FigCaptureSessionRemote.m:405 <<<< FigCaptureSessionRemote >>>> Fig assert: "err == 0 " at bail (FigCaptureSessionRemote.m:421) - (err=-16405) <<<< FigCaptureSessionRemote >>>> Fig assert: "msg" at bail (FigCaptureSessionRemote.m:744) - (err=0) Did I miss something?

With quite some excitement I read about visionOS 2's new feature to automatically turn regular 2D photos into spatial photos, using machine learning. It's briefly mentioned in this WWDC video: https://developer.apple.com/wwdc24/10166 My question is: Can developers use this feature via an API, so we can turn any image into a spatial image, even if it is not in the device photo library? We would like to download an image from our server, convert it on the visionPro on-the-fly and display it as a spatial photo.

Our app needs to scan QR codes (or a similar mechanism) to populate it with content the user wants to see. Is there any update on QR code scanning availability on this platform? I asked this before, but never got any feedback. I know that there is no way to access the camera (which is an issue in itself), but at least the system could provide an API to scan codes. (It would be also cool if we were able to use the same codes Vision Pro uses for detecting the Zeiss glasses, as long as we could create these via server-side JavaScript code.)
