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?

I'm seeing this error while attempting to compile my VisionOS app under Xcode 26. My existing code looks like:
let (naturalSize, formatDescriptions, mediaCharacteristics) = try? await videoTrack.load(.naturalSize, .formatDescriptions, .mediaCharacteristics)
This is now giving a compiler error: Type of expression is ambiguous without a type annotation
I don't see that anything that was changed or deprecated in the latest version. Also loading the properties individually seems to work fine i.e.:
let naturalSize = try? await videoTrack.load(.naturalSize)
let formatDescriptions = try? await videoTrack.load(.formatDescriptions)
let mediaCharacteristics = try? await videoTrack.load(.mediaCharacteristics)
I want to create a screenshot (static image) of the current view on the Apple Vision Pro using written code in visionOS. Unfortunately, I currently can’t find a way to achieve this. The only option I’ve found so far is through Reality Composer Pro. However, since I want to accomplish this directly through code, this approach is not an option for me.
Hello all, I saw this interesting VisionOS app: https://apps.apple.com/us/app/splitscreen-multi-display/id6478007837
I was wondering if there was any documentation on the Swift APIs that were used to create this app.
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"?

Hello,
I checked following documentations.
Vision | Apple Developer Documentation
Discover Swift enhancements in the Vision framework - WWDC24 - Videos - Apple Developer
I saw Vision Framework is available on visionOS.
So I want to know that if it's possible using Vision Framework on visionOS for tracking human and animal body poses. Or are there some limits to use this on visionOS?
I've been struggling with this for far too long so I've decided to finally come here and see if anyone can point me to the documentation that I'm missing. I'm sure it's something so simple but I just can't figure it out.
I can SharePlay our test app with my brother (device to device) but when I open a volumetric window, it says "not shared" under it. I assume this will likely fix the video sharing problem we have as well. Everything else works so smooth but SharePlay has just been such a struggle for me. It's the last piece to the puzzle before we can put it on the App Store.
Has anyone had success with MeshInstancesComponent? I tried to follow the sample code from What's New in RealityKit but it wouldn't compile. I was able to use one of the init overloads to get it to compile, but using it crashes both my device and the simulator. Even with one instance.
Hi there,
I was looking to add a particle emitter to my augmented reality app I'm developing using RealityKit. I'm targeting iOS. I noticed in the documentation for the ParticleEmitterComponent that it looks like iOS 18.0+ is supported, but when I try to use the ParticleEmitterComponent in my code in XCode, I get an error that it isn't found. Furthermore, this StackOverflow post seems to indicate that particle systems are not available for iOS. Would it be possible to get clarification on this?
At WWDC25 we launched a new type of Lab event for the developer community - Group Labs. A Group Lab is a panel Q&A designed for a large audience of developers. Group Labs are a unique opportunity for the community to submit questions directly to a panel of Apple engineers and designers. Here are the highlights from the WWDC25 Group Lab for visionOS.
I saw that there is a new way to add SwiftUI View attachments in my RealityView, what advantages does this have over the old way?
Attachments can now be added directly to your entities with ViewAttachmentComponent. The removes the need to declare your attachments upfront in your RealityView initializer and then add those attachments as child entities. The new approach provides greater flexibility. Canyon Crosser and Petite Asteroids both utilize the new approach.
ManipulationComponent looks really cool! Right now my app has a series of complicated custom gestures. What gestures does it handle for me exactly, and are there any situations where I should prefer my own custom gestures?
ManipulationComponent provides natural interaction with virtual objects. It seamlessly handles translation and rotation. You can easily add manipulation to a SwiftUI view like Model3D with the manipulable view modifier.
The new Object Manipulation API is great for most apps, and is a breeze to implement, but sometimes you might want a more custom feel, and that’s ok! Custom gestures are still fully supported for that scenario.
I saw that there is a new API to also access the right main camera. What can I do with this?
Correct, in visionOS 26, you can access the left and right main cameras. You can even access them simultaneously as a stereo pair. Camera access still requires a managed entitlement and an enterprise license, see Accessing the main camera for more details about those requirements.
More computer vision and machine learning use-cases are unlocked with access to both cameras, we are excited to see what you will do!
What do I need to do to add spatial accessory input for my app?
First, use the GameController framework to establish a connection with the spatial accessory, and then listen for events from the controller. Then, you can use either RealityKit, ARKit, or a combination of both to track the accessory, anchor virtual content to it, and fine tune the accessory interaction with the content in your app.
For more details, check out Discovering and tracking spatial game controllers and styli.
By far, the most difficulty with implementing visionOS apps is SwiftUI window management…placing, opening, closing, etc. Are there any improvements to window management in visionOS 26?
Yes! We recommend watching Set the scene with SwiftUI in visionOS.
You can use the defaultLaunchBehavior to choose whether a particular window is presented (or suppressed) at launch. You can also prevent a window like a secondary toolbar from launching as the initial window using .restorationBehavior(.disabled). Adopting best practices for persistent UI provides a great overview of SwiftUI window management on visionOS.
As for placing windows, there is still no API for an app to specify the placement of its windows other than relative placement. If that is a feature you are interested in, please file an enhancement request for it using Feedback Assistant!
How to get access to the Enterprise API?
First, request the entitlement and license through your Apple Developer or enterprise account. Once these have been granted, include the license and entitlement in your project. Then you can build, test, and distribute as an in-house app.

Hi ,
I'm struggling with visionOS window management and need help with closing child windows programmatically.
App Structure
My app has a Main-Sub window hierarchy:
AWindow (Home/Main)
BWindow (Main feature window)
CWindow (Tool window - child of BWindow)
Navigation flow:
AWindow → BWindow (switch, 1 window on screen)
BWindow → CWindow (opens child, 2 windows on screen)
I want BWindow and CWindow to be separate movable windows (not sheet/popover) so users can position them independently in space.
The Problem
CWindow doesn't close when BWindow closes by tapping the X button below the app (next to the window bar)
User clicks X on BWindow → BWindow closes but CWindow remains
CWindow becomes orphaned on screen
Can close CWindow programmatically when switching BWindow back to AWindow
App launch issue
After closing both windows, CWindow is remembered as last window
Reopening app shows only CWindow instead of BWindow
User gets stuck in CWindow with no way back to BWindow
I've Tried Environment dismissWindow in cleanup but its not working.
// In BWindow.swift
.onDisappear {
if windowManager.isWindowOpen("cWindow") {
dismissWindow(id: "cWindow")
}
}
My App Structure Code Now
// in MyNameApp.swift
@main
struct MyNameApp: App {
var body: some Scene {
WindowGroup(id: "aWindow") {
AWindow()
}
WindowGroup(id: "bWindow") {
BWindow()
}
WindowGroup(id: "cWindow") {
CWindow()
}
}
}
// WindowStateManager.swift
class WindowStateManager: ObservableObject {
static let shared = WindowStateManager()
@Published private var openWindows: Set<String> = []
@Published private var windowDependencies: [String: String] = [:]
private init() {}
func markWindowAsOpen(_ id: String) {
markWindowAsOpen(id, parent: nil)
}
func markWindowAsClosed(_ id: String) {
openWindows.remove(id)
windowDependencies[id] = nil
}
func isWindowOpen(_ id: String) -> Bool {
let isOpen = openWindows.contains(id)
return isOpen
}
func markWindowAsOpen(_ id: String, parent: String? = nil) {
openWindows.insert(id)
if let parentId = parent {
windowDependencies[id] = parentId
}
}
func getParentWindow(of childId: String) -> String? {
let parent = windowDependencies[childId]
return parent
}
func getChildWindows(of parentId: String) -> [String] {
let children = windowDependencies.compactMap { key, value in
value == parentId ? key : nil
}
return children
}
func setNextWindowParent(_ parentId: String) {
UserDefaults.standard.set(parentId, forKey: "nextWindowParent")
}
func getAndClearNextWindowParent() -> String? {
let parent = UserDefaults.standard.string(forKey: "nextWindowParent")
UserDefaults.standard.removeObject(forKey: "nextWindowParent")
return parent
}
func forceCloseChildWindows(of parentId: String) {
let children = getChildWindows(of: parentId)
for child in children {
markWindowAsClosed(child)
NotificationCenter.default.post(
name: Notification.Name("ForceCloseWindow"),
object: nil,
userInfo: ["windowId": child]
)
forceCloseChildWindows(of: child)
}
}
func hasMainWindowOpen() -> Bool {
let mainWindows = ["main", "bWindow"]
return mainWindows.contains { isWindowOpen($0) }
}
func cleanupOrphanWindows() {
for (child, parent) in windowDependencies {
if isWindowOpen(child) && !isWindowOpen(parent) {
NotificationCenter.default.post(
name: Notification.Name("ForceCloseWindow"),
object: nil,
userInfo: ["windowId": child]
)
markWindowAsClosed(child)
}
}
}
}
// BWindow.swift
struct BWindow: View {
@Environment(\.dismissWindow) private var dismissWindow
@ObservedObject private var windowManager = WindowStateManager.shared
var body: some View {
VStack {
Button("Open C Window") {
windowManager.setNextWindowParent("bWindow")
openWindow(id: "cWindow")
}
}
.onAppear {
windowManager.markWindowAsOpen("bWindow")
}
.onDisappear {
windowManager.markWindowAsClosed("bWindow")
windowManager.forceCloseChildWindows(of: "bWindow")
}
.onChange(of: scenePhase) { oldValue, newValue in
if newValue == .background || newValue == .inactive {
windowManager.forceCloseChildWindows(of: "bWindow")
}
}
}
}
// CWindow.swift
import SwiftUI
struct cWindow: View {
@ObservedObject private var windowManager = WindowStateManager.shared
@State private var shouldClose = false
var body: some View {
// Content
}
.onDisappear {
windowManager.markWindowAsClosed("cWindow")
NotificationCenter.default.removeObserver(
self,
name: Notification.Name("ForceCloseWindow"),
object: nil
)
}
.onChange(of: scenePhase) { oldValue, newValue in
if newValue == .background {
}
}
.onAppear {
let parent = windowManager.getAndClearNextWindowParent()
windowManager.markWindowAsOpen("cWindow", parent: parent)
NotificationCenter.default.addObserver(
forName: Notification.Name("ForceCloseWindow"),
object: nil, queue: .main) { notification in
if let windowId = notification.userInfo?["windowId"] as? String, windowId == "cWindow" {
shouldClose = true
}
}
}
.onChange(of: shouldClose) { _, newValue in
if newValue {
dismissWindow()
}
}
}
The logs show everything executes correctly, but CWindow remains visible on screen.
Questions
Why doesn't dismissWindow(id:) work in cleanup scenarios?
Is there a proper way to create a window relationships like parent-child relationships in visionOS?
How can I ensure main windows open on app launch instead of tool windows?
What's the recommended pattern for dependent windows in visionOS?
Environment: Xcode 16.2, visionOS 2.0, SwiftUI
After updating to visionOS 26.2 Beta 2 (and Beta 3), I'm unable to establish a spatial connection to Vision Pro. This was working fine before the update.
To test, I've created a fresh spatialApp project from the Xcode template with zero modifications, but I'm hitting the same issue - the Vision Pro is discovered but won't connect.
Am I forgetting to update the config somewhere? Any ideas what might be causing this and how to fix it?
Thanks!

I want to let users place 2D/3D “artworks” on detected walls and have them reappear in exactly the same real‑world spot after quitting and relaunching the app (like widgets do, but for my own entities).Environment: Xcode 26, visionOS 2.0, RealityKit + ARKitSession/WorldTrackingProvider Entities are parented to a holder that’s aligned to a wall via plane/mesh raycasts.
What I’ve tried:
Create a WorldAnchor at placement, save UUID + full 4×4 transform On next launch, re-create the WorldAnchor (or set the saved transform) and attach the entity Gate restore on relocalization/mesh updates and disable all raycast/search after restore Issue: After relaunch, placement still resolves relative to current device pose, not the same wall position.
Questions:
Is there a public API in visionOS 2.0 to persist app‑managed world anchors across sessions (room‑fixed), e.g., AnchorStore or equivalent?
If not, what’s the recommended pattern to reliably restore wall‑anchored content?
Are persistence features mentioned for widgets/windows available to third‑party RealityKit entities?
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 ,

I’ve submitted the following feedback:
FB13820942 (List Outline View Not Using Accent Color on Disclosure Caret for visionOS)
I’d appreciate help on this to see if I’m doing something wrong or indeed it’s the way visionOS currently works and it’s a suggested feedback.
I'm trying to develop an app that broadcasts what the user sees (priorly we were using main camera access) but now we'd like to investigate and try with this option.
I have set up the BroadcastExtension, I've added the picker, I click on my button, I can see my broadcast extension in the options list in the control center, once I click start, it stops after 1 second more or less.
I'm not able to get anything in the console from my Sample Handler (prints or logs or anything).
I can see however in the console.app some misleading information (one after the other):
[INFO] -[RPRecordingManager getSystemBroadcastExtensionInfo:]_block_invoke:1333 Extension has passthrough license
[INFO] -[RPRecordingManager getSystemBroadcastExtensionInfo:]_block_invoke:1336 Extension does not have passthrough license
We have the entreprise license, the capability and I did add the capability on the extension target as well.
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'm currently implementing 180° / 360° immersive video for my app.
I easily implemented 360° by just applying VideoMaterial to flipped sphere.
But I'm stuck at 180°. I'm trying to implement by applying VideoMaterial to hemisphere (half sphere). I want to make VideoMaterial to be visible half front sphere and half back sphere transparent / clear.
Would there be any advice / information / idea to implement this? Your help would be grateful.
prefetching logic for UICollectionView on VisionOS does not work.
I have set up a Standalone test repo to demonstrate this issue. This repo is basically a visionOS version of Apple's guide project on implementation of prefetching logic.
in repo you will see a simple ViewController that has UICollectionView, wrapped inside UIViewControllerRepresentable.
on scroll, it should print 🕊️ prefetch start on console to demonstrate func collectionView(_ collectionView: UICollectionView, prefetchItemsAt indexPaths: [IndexPath]) is called. However it never happens on VisionOS devices.
With the same code it behaves correctly on iOS devices
