Hi, I'm working on a VisionOS app and would like to integrate Background Assets to download large files after the app is installed.
I'm wondering what would happen if the user takes off the headset while a background asset is being downloaded. Would it continue downloading or would the download be stopped/paused?
I was looking for a way to download large assets while the user is not wearing the Vision Pro, is there any other alternative?
Thanks in advance.

Hi, we would like to create something where you can open multiple volumetric windows and place them in a room, our biggest issue is that we want these windows to be persistent, so when I close and reopen the app, the windows to be in the same position. We can't use immersive spaces because we also want to have the possibility to access the shared space.
Is it possible with the current features and capabilities to do that? If yes do you have some advices how can we achieve this?
The alternative is if is it possible to open the virtual display in immersive spaces or if we have the possibility to implement our own virtual display.
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.
Platform: visionOS 2.6
Framework: RealityKit, SwiftUIComponent: ImagePresentationComponent
I’m working with the new ImagePresentationComponent from visionOS 26 and hitting a rendering limitation when switching to .spatialStereoImmersive viewing mode within a WindowGroup context.
This is what I’m seeing:
Pure immersive space: ImagePresentationComponent with .spatialStereoImmersive mode works perfectly in a standalone ImmersiveSpace
Mode switching API: All mode transitions work correctly (logs confirm the component updates)
Spatial content: .spatialStereo mode renders correctly in both window and immersive contexts.
This is where it’s breaking for me:
Window context: When the same RealityView + ImagePresentationComponent is placed inside a WindowGroup (even when that window is floating in a mixed immersive space), switching to .spatialStereoImmersive mode shows no visual change
The API calls succeed, state updates correctly, but the immersive content doesn’t render.
Apple’s Spatial Gallery demonstrates exactly what I’m trying to achieve:
Spatial photos displayed in a window with what feels like horizontal scroll view using system window control bar, etc.
Tapping a spatial photo smoothly transitions it to immersive mode in-place.
The immersive content appears to “grow” from the original window position by just changing IPC viewing modes.
This proves the functionality should be possible, but I can’t determine the correct configuration.
So, my question to is:
Is there a specific RealityView or WindowGroup configuration required to enable immersive content rendering from window contexts that you know of?
Are there bounds/clipping settings that need to be configured to allow immersive content to “break out” of window constraints?
Does .spatialStereoImmersive require a specific rendering context that’s not available in windowed RealityView instances?
How do you think Apple’s SG app achieves this functionality?
For a little more context:
All viewing modes are available: [.mono, .spatialStereo, .spatialStereoImmersive]
The spatial photos are valid and work correctly in pure immersive space
Mixed immersive space is active when testing window context
No errors or warnings in console beyond the successful mode switching logs I’m getting
Any insights into the proper configuration for window-hosted immersive content
Hello everyone
I would like to create my own spatial video on my Apple Vision Pro. According to all the documentation from Apple, this requires two camera angles that enhance the spatial perception. I have purchased the Enterprise license with main camera access for this purpose. However, this only gives me access to the left main camera of the glasses. Is there a way to access the right camera as well? Or is the one camera image enough to create a spatial video by splitting the image, for example?
I am open to any help and ideas. My goal is to create the video with the cameras on the glasses, not externally.
Is it possible to create a button in my app that will turn on the spatial personas for the user? Currently the only way I know of turning on spatial personas is by selecting the cube icon in the FaceTime window which is quite clunky for people unfamiliar with the Vision Pro's UI. Any help would be appreciated.
I'm playing about with the hand tracking systems in reality kit / Vision Pro
I thought it would be interesting if I could attach a virtual object to a hand when the hand is gripping (thought it would be fun to attach a basic cylinder to mimic a wand from Harry Potter)
I'm able to detect when the user is gripping but having trouble placing an object as though it's within the hand.
The simplest version of this is using an AnchorEntity pointing to the user's palm which kind of works, but quickly breaks the illusion when you rotate the wrist or hand.
It seems as though I will have to roll my own anchor entity using the various points of the user's hand and I thought calculating some median point between the thumb and little finger tips would be a good start but it's proven a little difficult as we need both rotation and position.
I'm already out of my depth with reality kit and matrices (and thanks to ChatGPT) I have some code, but as soon as I apply the position manually (as opposed to a hand anchor entity) it fails to render on the user's hand.
It feels like this should already have been something someone has looked in to, any ideas on what might be the issue here?
Note: HandTrackingSystem.handTracking is a HandTrackingProvider()
guard let anchors = HandTrackingSystem.handTracking.latestAnchors.leftHand else {
return
}
if
let thumb = anchors.handSkeleton?.joint(.thumbTip),
let little = anchors.handSkeleton?.joint(.littleFingerTip)
{
let thumbPos = simd_make_float3(thumb.anchorFromJointTransform.columns.3)
let littlePos = simd_make_float3(little.anchorFromJointTransform.columns.3)
let midPos = (thumbPos + littlePos) / 2
let direction = normalize(littlePos - thumbPos)
let rotation = simd_quatf(from: [0, 1, 0], to: direction)
wandEntity.transform.translation = midPos
wandEntity.transform.rotation = rotation
content.add(wandEntity)
}
Hello since updating to beta 3 the sculpting sample app doesn't work it crashes on running.
seems to be something in AnchorEntity or AccessoryAnchoringSource

Hi, I am a new developer. I want to add articulated objects and deformable objects into my AR game. I haven't found any tutorial on this, I hope to interact with these objects. Please let me know if this is available in visionOS.
I’m working on a Vision Pro app using Metal and need to implement multi-pass rendering. Specifically, I want to render intermediate results to a texture, then use that texture in a second pass for post-processing before presenting the final output.
What’s the best approach in visionOS? Should I use multiple render passes in a single command buffer or separate command buffers? Any insights on efficiently handling this in RealityKit or Metal?
Thanks!
I want to step into portal world. I've know PortalCrossingComponent can make an entity to cross portal, but how to make device cross into portal world?
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.
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?
When you click the button in the background of three horizontal lines, when the view is about to appear, add buried event statistics, but click the button to close it, it will repeat the view will appear method API, equivalent to the view method repeated execution twice, resulting in incorrect buried event statistics
I have been trying to implement this look where a component looks "pushed in" but I could not find any resources regarding this effect. The closest I got was a combination of a RoundedRectangle and .glassBackgroundEffect(), but this makes the view look pushed out, instead of pushed in.
I was wondering if this is achievable in SwiftUI level, or even in UIKit level.
One of the most common ways to provide a window size in visionOS is to use the defaultSize scene modifier.
WindowGroup(id: "someID") {
SomeView()
}
.defaultSize(CGSize(width: 600, height: 600))
Starting in visionOS 26, using this has a side effect. visionOS 26 will restore windows that have been locked in place or snapped to surfaces. If a user has manually adjusted the size of a locked/snapped window, the users size is only restore in some cases.
Manual resize respected
Leaving a room and returning later
Taking the headset off and putting it back on later
Manual resize NOT respected
Device restart. In this case, the window is reopened where it was locked, but the size is set back to the values passed to defaultSize. The manual resizing adjustments the user has made are lost. This is counter to how all other windows and widgets work.
I reported this last month (FB18429638), but haven't heard back if this is a bug or intended behavior.
Questions
What is the best way to provide a default window size that will only be used when opening new windows–and not used during scene restoration?
Should we try to keep track of window size after users adjust them and save that somewhere?
If this is intended behavior, can someone please update the docs accordingly?
If I trigger the apple rating modal in an Immersive space it appears on the ground in (0,0,0) I need it to be in front of the user like push notification perimssion does or other permissions requests.
Hi there,
I’m building a workplace experience that requires using virtual desktop, is there a way to launch it in my code, so user doesn’t have to do it manually?
Thanks in advance!
I want to record animation with entity, then export it to .usd without using Reality Composer Pro, how to achieve that?
I am trying to get the new PresentationComponent working in VisionOS26 as seen in this WWDC video:
https://developer.apple.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)
}
}
}
}
}
