My VisionOS App (Travel Immersive) has two interface windows: a main 2D interface window and a 3D Earth window. If the user first closes the main interface window and then the Earth window, clicking the app icon again will only launch the Earth window while failing to display the main interface window. However, if the user closes the Earth window first and then the main interface window, the app restarts normally.
Below is the code of
import SwiftUI
@main
struct Travel_ImmersiveApp: App {
@StateObject private var appModel = AppModel()
var body: some Scene {
WindowGroup(id: "MainWindow") {
ContentView()
.environmentObject(appModel)
.onDisappear {
appModel.closeEarthWindow = true
}
}
.windowStyle(.automatic)
.defaultSize(width: 1280, height: 825)
WindowGroup(id: "Earth") {
if !appModel.closeEarthWindow {
Globe3DView()
.environmentObject(appModel)
.onDisappear {
appModel.isGlobeWindowOpen = false
}
} else {
EmptyView() // 关闭时渲染空视图
}
}
.windowStyle(.volumetric)
.defaultSize(width: 0.8, height: 0.8, depth: 0.8, in: .meters)
ImmersiveSpace(id: "ImmersiveView") {
ImmersiveView()
.environmentObject(appModel)
}
}
}

I have a scene that has been assembled in RCP but I'm losing the correct hierarchy and transforms when running the scene in the headset or the simulator.
This is in RCP:
This is at runtime with the debugger:
As you can see the "MAIN_WAGON" entity is gone and part of the hierarchy are now children of "TRAIN_ROOT" instead.
Another issue is that not only part of the hieararchy disappears, it also reverts back to default values of the transform instead of what is set in RCP:
This is in RCP:
This is in the simulator/headset:
I'm filing a feedback ticket too and will post the number here.
Anyone had a similar issue and found a fix or workaround ?

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
I exported some usd assets from IsaacSim but they are not showing up correctly on my Apple Vision Pro.
Even though the mesh looks to be the correct color in Finder and I can see the Diffuse Color looks correct, the object is still just gray. It should be green!
I'm developing a visionOS panorama viewer app where I need to implement an auto-hiding floating menu in immersive space. The menu should:
Show for 3 seconds when entering immersive mode
Auto-hide after 3 seconds,
Reappear when user taps anywhere (using SpatialTapGesture).
Buttons should respond to gaze + pinch interaction
The Problem:
When I add .windowStyle(.plain) to achieve transparent window background for the auto-hide effect, all buttons in the menu become completely unresponsive to gaze + pinch interaction. The buttons only respond to direct finger touch (poking).
Without .windowStyle(.plain): Buttons work correctly with gaze + pinch, but I cannot achieve transparent window background for hiding.
With .windowStyle(.plain): Window can be transparent, but buttons lose gaze + pinch interaction.
Code:
App.swift:
@main
struct MyApp: App {
@StateObject private var model = AppModel()
var body: some Scene {
WindowGroup(id: "MainWindow") {
ContentView()
.environmentObject(model)
}
.defaultSize(width: 900, height: 700)
.windowResizability(.contentSize)
.windowStyle(.plain) // <-- This causes the interaction issue
ImmersiveSpace(id: "ImmersiveSpace") {
ImmersiveView()
.environmentObject(model)
}
}
}
ContentView.swift (simplified):
struct ContentView: View {
@EnvironmentObject var model: AppModel
@State private var isMenuVisible: Bool = true
var body: some View {
VStack {
if model.isImmersiveViewActive {
if isMenuVisible {
// This menu's buttons don't respond to gaze+pinch
immersiveControlMenu
}
} else {
mainMenuButtons
}
}
.glassBackgroundEffect()
}
private var immersiveControlMenu: some View {
HStack {
Button("Exit") {
exitImmersiveSpace()
}
.buttonStyle(.bordered) // Also tried .plain, same issue
}
.padding()
.glassBackgroundEffect()
}
}
ImmersiveView.swift:
struct ImmersiveView: View {
@EnvironmentObject var model: AppModel
var body: some View {
RealityView { content in
// Panorama sphere
let sphere = ModelEntity(mesh: .generateSphere(radius: 1000), materials: [material])
content.add(sphere)
// Tap detector for menu toggle
let tapDetector = Entity()
tapDetector.components.set(CollisionComponent(shapes: [.generateSphere(radius: 900)]))
tapDetector.components.set(InputTargetComponent())
content.add(tapDetector)
}
.gesture(
SpatialTapGesture()
.targetedToAnyEntity()
.onEnded { _ in
model.shouldShowMenu = true
}
)
}
}
Environment:
Xcode 26.2
visionOS 26.3
Vision Pro device
Questions:
Is .windowStyle(.plain) expected to affect button interaction behavior?
What is the recommended approach to achieve a transparent/hidden window in immersive mode while maintaining button interactivity?
Is there an alternative to .windowStyle(.plain) for hiding window chrome in visionOS?
Thank you for any guidance!
What is the reason the hand-tracking joints have these axes? I'm trying to create a virtual hands model and that's a mess.
`error: [xrsimulator] Component Compatibility: EnvironmentLightingConfiguration not available for 'xros 1.0', please update 'platforms' array in Package.swift

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.
The new Mac virtual display feature on visionOS 2 offers a curved/panoramic window. I was wondering if this is simply a property that can be applied to a window, or if it involves an immersive mode or SceneKit/RealityKit?
I am testing out the Gen 2 of the developer strap on my Vision Pro M2 and I have only been able to get USB 2 speeds when connecting it to my MacBook Pro Max M3. I used the official Apple Thunderbolt 4 cable, which does get Thunderbolt speeds on my T7 Touch drive. Has anyone figured out a solution for this issue?
The Gen 2 developer strap does advertise 20 Gb/s speeds.

Hello,
I'm working with the new PortalComponent introduced in visionOS 2.0, and I've encountered some issues when transitioning entities between virtual and real-world spaces using crossingMode.
Specifically:
Lighting inconsistency: When CG content (ModelEntities with PhysicallyBasedMaterial) crosses the portal from virtual space into the real environment, the way light reflects on the objects changes noticeably. This causes a jarring visual effect, as the same material appears differently depending on the space it's in.
Unnatural transition visuals: During the transition, the CG models often appear to "emerge from the wall," especially when crossing from virtual to real. This ruins the immersive illusion and feels visually unnatural.
IBL adjustment attempts: I’ve tried adding an ImageBasedLightComponent to the world entity, and while it slightly improves the lighting consistency, the issue still remains to a noticeable degree.
My goal is to create a seamless visual experience when CG entities cross between spaces, without sudden lighting shifts or immersion-breaking geometry reveals.
Has anyone else experienced similar issues?
Is there a recommended setup or workaround to better control lighting and visual fidelity when using crossingMode with portals in visionOS 2.0?
Any guidance would be greatly appreciated.
Thank you!
Hi, I am trying to load files from the Apple Vision Pro's storage into a Unity App (using Apple visionOS XR Plugin and not PolySpatial package). So far, I've tried using UnitySimpleFileBrowser and UnityStandaloneFileBrowser (both aren't made for the Vision Pro and don't work there), and then implemented my own naive file browser that at least allows me to view directories (that I can see from the App Sandbox). This is of course very limited:
Gray folders can't be accessed, the only 3 available ones don't contain anything where a user would put files through the "Files" app.
I know that an app can request access to these "Files & Folders":
So my question is: Is there a way to request this access for a Unity-built app at the moment? If yes, what do I need to do? I've looked into the generated Xcode project's "Capabilities", but did not find anything related to file access. Any help is appreciated!
This is related to the WWDC presentation, What's new in Metal rendering for immersive apps..
Specifically, the macOS spatial streaming to visionOS feature: For reference: the page in the docs.
The presentation demonstrates it using a full immersive space and Metal rendering using compositor services.
I'd like clarity on a few things:
Is the remote device wireless, or must the visionOS device be connected via a wired connected?
Is there a limit to the number of remote devices, and if not, could macOS render different things per remote device simultaneously?
Can I also use mixed mode with passthrough enabled, instead of just a fully-immersive mode?
Can I use RealityKit instead of Metal? If so, may I have an example, or would someone point to an example?
I'm having a heck of a time getting this to work. I'm trying to add an event notification at the end of a timeline animation to trigger something in code but I'm not receiving the notification from RC Pro. I've watched that Compose Interactive 3D Content video quite a few times now and have tried many different ways. RC Pro has the correct ID names on the notifications. I'm not a programmer at all. Just a lowly 3D artist. Here is my code...
import SwiftUI
import RealityKit
import RealityKitContent
extension Notification.Name {
static let button1Pressed = Notification.Name("button1pressed")
static let button2Pressed = Notification.Name("button2pressed")
static let button3Pressed = Notification.Name("button3pressed")
}
struct MainButtons: View {
@State private var transitionToNextSceneForButton1 = false
@State private var transitionToNextSceneForButton2 = false
@State private var transitionToNextSceneForButton3 = false
@Environment(AppModel.self) var appModel
@Environment(\.dismissWindow) var dismissWindow
// Notification publishers for each button
private let button1PressedReceived = NotificationCenter.default.publisher(for: .button1Pressed)
private let button2PressedReceived = NotificationCenter.default.publisher(for: .button2Pressed)
private let button3PressedReceived = NotificationCenter.default.publisher(for: .button3Pressed)
var body: some View {
ZStack {
RealityView { content in
// Load your RC Pro scene that contains the 3D buttons.
if let immersiveContentEntity = try? await Entity(named: "MainButtons", in: realityKitContentBundle) {
content.add(immersiveContentEntity)
}
}
// Optionally attach a gesture if you want to debug a generic tap:
.gesture(
TapGesture().targetedToAnyEntity().onEnded { value in
print("3D Object tapped")
_ = value.entity.applyTapForBehaviors()
// Do not post a test notification here—rely on RC Pro timeline events.
}
)
}
.onAppear {
dismissWindow(id: "main")
// Remove any test notification posting code.
}
// Listen for distinct button notifications.
.onReceive(button1PressedReceived) { (output) in
print("Button 1 pressed notification received")
transitionToNextSceneForButton1 = true
}
.onReceive(button2PressedReceived.receive(on: DispatchQueue.main)) { _ in
print("Button 2 pressed notification received")
transitionToNextSceneForButton2 = true
}
.onReceive(button3PressedReceived.receive(on: DispatchQueue.main)) { _ in
print("Button 3 pressed notification received")
transitionToNextSceneForButton3 = true
}
// Present next scenes for each button as needed. For example, for button 1:
.fullScreenCover(isPresented: $transitionToNextSceneForButton1) {
FacilityTour()
.environment(appModel)
}
// You can add additional fullScreenCover modifiers for button 2 and 3 transitions.
}
}

When I show a window while a sky sphere is shown, the handles to drag/close/resize the window are hidden. The colliders still work, so they are there, but only the visuals are hidden. I already know from another project, that this also happens to volumes.
They only appear once you get closer to the window or if the sky sphere gets removed.
Is this a known issue or is there a fix for that?
.persistentSystemOverlays(.visible)does not fix it
Xcode 16.3.0 Beta, visionOS 2.4
I want adding grounding shadow on my Entity in RealityView on visionPro. However it seems that the shadow can only appear on another Entity. So I using plane detection in ARKit and add a transparent plane on it to render shadow.
let planeEntity = ModelEntity(mesh: .generatePlane(width: anchor.geometry.extent.width, height: anchor.geometry.extent.height), materials: [material])
planeEntity.components.set(OpacityComponent(opacity: 0.0))
But sometimes there will be a border around my Entityon the plane.
I do not know why it will happen, and I want remove the border.
The issue reproducible with empty project. When you run it and tap "Open immersive space" it takes a couple of minutes to respond. The issue only reproducible on real device with debugger attached. Reproducible other developers too (not specific to my environment). Issue doesn't exists in Xcode 16.
Afer initial long delay subsequent opens works fine.

How do you call the effect where the edges around the central image gradually become transparent? This effect is also seen when viewing immersive mode of spatial photos in Vision Pro. How can I achieve this effect using SwiftUI or ShaderGraph? I want to use this effect when displaying images in my app.
Reality Composer is no longer available in XCode 15 Release. Is this intended or will be available in later releases? Do I need to revert to Xcode15 Beta8 to get Reality Composer?
The WWDC25 video and notes titled “Learn About Apple Immersive Video Technologies” introduced the Apple Spatial Audio Format (ASAF) and codec (APAC). However, despite references throughout on using immersive video, there is scant information on ASAF/APAC (including no code examples and no framework references), and I’ve found no documentation in Apple’s APIs/Frameworks about its implementation and use months on.
I want to leverage ambisonic audio in my app. I don’t want to write a custom AU if APAC will be opened up to developers. If you read the notes below along with the iPhone 17 advertising (“Video is captured with Spatial Audio for immersive listening”), it sounds like this is very much a live feature in iOS26.
Anyone know the state of play? I’m across how the PHASE engine works, which is unrelated to what I’m asking about here.
Original quote from video referenced above: “ASAF enables truly externalized audio experiences by ensuring acoustic cues are used to render the audio. It’s composed of new metadata coupled with linear PCM, and a powerful new spatial renderer that’s built into Apple platforms. It produces high resolution Spatial Audio through numerous point sources and high resolution sound scenes, or higher order ambisonics.”
”ASAF is carried inside of broadcast Wave files with linear PCM signals and metadata. You typically use ASAF in production, and to stream ASAF audio, you will need to encode that audio as an mp4 APAC file.”
”APAC efficiently distributes ASAF, and APAC is required for any Apple immersive video experience. APAC playback is available on all Apple platforms except watchOS, and supports Channels, Objects, Higher Order Ambisonics, Dialogue, Binaural audio, interactive elements, as well as provisioning for extendable metadata.”
