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.

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.
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)
}
I am experiencing an issue where USDZ files exported from Blender do not display textures when opened in Apple Vision Pro Quick Look. Instead of the expected materials, the model appears completely white, as if the textures are missing or not being recognized by the rendering engine.

I really love the immersive environments, but I don’t have experience with creating them. Do you have resources or tutorials you can recommend for creating these from scratch? I’ve seen the sample projects and videos, but they usually start in the middle, assuming you already have the assets created.

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

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?
If I update vision pro size then textfield and button are not update as per its new size.
Its working on some scren but not in some screen.
Please refer below screenshot for your reference,
my coworkers and i are guessing at what data defines an anchor. i tried searching but struggled to find anything helpful.
our best guess was a combination Triangular Irregular Networks (TIN), gps, magnetic compass direction and maybe elevation sensors.
is this documented anywhere? if not, can a definition or description be provided?
In Vision OS app, I have two types of windows:
Main App Window – This is the default window that launches when the app starts. It displays the video listings and other primary content.
Immersive Space Window – This opens only when a user starts streaming or playing a video.
Issue:
When entering the immersive space, the main app window remains visible in front of it unless manually closed. To avoid this, I currently close the main window when transitioning to immersive space and reopen it when exiting from immersive space. However, this causes the app to restart instead of resuming from its previous state.
Desired Behavior:
I want the main app window to retain its state and seamlessly resume from where it was before entering immersive mode, rather than restarting.
Attempts & Challenges:
Tried managing opacity, visibility but none worked as expected.
Couldn’t find a way to push the main window to the background while bringing the immersive space to the foreground.
Looking for a solution to keep the main window’s state intact while transitioning between immersive and normal modes.
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?
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.
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?
Hi team I don't know from this error has popped up any suggestions please
Thanks

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)
}
}
}
}
}
Here is the Apple reference: https://developer.apple.com/documentation/realitykit/presentationcomponent
Hello! I’m excited to see that Look to Scroll has been included in visionOS 26 Beta. I’m aiming to achieve a feature where the user’s gaze at a specific edge automatically scrolls to that position. However, I’ve experimented with ScrollView and haven’t been able to trigger this functionality. Could you advise if additional API modifiers are necessary? Thank you!
Can I combine FromToByAction and BindTarget.MaterialPath to animate my ShaderGraphMaterial. I don't know how to use the BindTarget.MaterialPath.
I have a mesh based animation 3D model, that means every frame it’s a new mesh. I import it into RealityView, but can’t play it‘s animation, RealityKit tells me this model has no animations by using print(entity.availableAnimations).
So, I was trying to animate a single bone using FromToByAnimation, but when I start the animation, the model instead does the full body animation stored in the availableAnimations.
If I don't run testAnimation nothing happens.
If I run testAnimation I see the same animation as If I had called
entity.playAnimation(entity.availableAnimations[0],..)
here's the full code I use to animate a single bone:
func testAnimation() {
guard let jawAnim = jawAnimation(mouthOpen: 0.4) else {
print("Failed to create jawAnim")
return
}
guard let creature, let animResource = try? AnimationResource.generate(with: jawAnim) else { return }
let controller = creature.playAnimation(animResource, transitionDuration: 0.02, startsPaused: false)
print("controller: \(controller)")
}
func jawAnimation(mouthOpen: Float) -> FromToByAnimation<JointTransforms>? {
guard let basePose else { return nil }
guard let index = basePose.jointNames.firstIndex(of: jawBoneName) else {
print("Target joint \(self.jawBoneName) not found in default pose joint names")
return nil
}
let fromTransforms = basePose.jointTransforms
let baseJawTransform = fromTransforms[index]
let maxAngle: Float = 40
let angle: Float = maxAngle * mouthOpen * (.pi / 180)
let extraRot = simd_quatf(angle: angle, axis: simd_float3(x: 0, y: 0, z: 1))
var toTransforms = basePose.jointTransforms
toTransforms[index] = Transform(
scale: baseJawTransform.scale * 2,
rotation: baseJawTransform.rotation * extraRot,
translation: baseJawTransform.translation
)
let fromToBy = FromToByAnimation<JointTransforms>(
jointNames: basePose.jointNames,
name: "jaw-anim",
from: fromTransforms,
to: toTransforms,
duration: 0.1,
bindTarget: .jointTransforms,
repeatMode: .none,
)
return fromToBy
}
PS: I can confirm that I can set this bone to a specific position if I use
guard let index = newPose.jointNames.firstIndex(of: boneName) ...
let baseTransform = basePose.jointTransforms[index]
newPose.jointTransforms[index] = Transform(
scale: baseTransform.scale,
rotation: baseTransform.rotation * extraRot,
translation: baseTransform.translation
)
skeletalComponent.poses.default = newPose
creatureMeshEntity.components.set(skeletalComponent)
This works for manually setting the bone position, so the jawBoneName and the joint-transformation can't be that wrong.
