I want an AR character to be able to look at a position while still playing the characters animation.
So far, I managed to manually adjust a single bone rotation using
skeletalComponent.poses.default = Transform(
scale: baseTransform.scale,
rotation: lookAtRotation,
translation: baseTransform.translation
)
which I run at every rendering update, while a full body animation is running.
But of course, hardcoding single joints to point into a direction (in my case the head) does not look as nice, as if I were to run some inverse cinematic that includes, hips + neck + head joints.
I found some good IKRig code in Composing interactive 3D content with RealityKit and Reality Composer Pro.
But when I try to adjust rigs while animations are playing, the animations are usually winning over the IKRig changes to the mesh.

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'm trying to add a feature to my app to allow a user to import items from other apps, like Safari, via the share sheet.
I've done this many times on iOS/iPadOS easily with a Share Extension. From what I can tell, Xcode tells me share extensions are not available on visionOS - though my experience on device tells me differently (It seems Reminders, Notes & more implement them somehow.) I was finally able to get it working on device only...but I can now no longer test in the simulator, and have not found a way to distribute this app.
When attempting to run on the simulator, I get this issue:
Please try again later. Appex bundle at /Users/jason/Library/Developer/CoreSimulator/Devices/09A70160-4F4F-4F5E-B679-F6F7D876D7EF/data/Library/Caches/com.apple.mobile.installd.staging/temp.6OAEZp/extracted/LaunchBar.app/PlugIns/LaunchBarShareExtension.appex with id co.swiftfox.LaunchBar.ShareExtension specifies a value (com.apple.share-services) for the NSExtensionPointIdentifier key in the NSExtension dictionary in its Info.plist that does not correspond to a known extension point.
When trying to archive an upload to test flight, I get this similar error:
Invalid Info.plist value. The value for the key 'DTPlatformName' in bundle LaunchBar.app/PlugIns/LaunchBarShareExtension.appex is invalid. (ID: 207610c7-b7e1-48be-959b-22a43cd32d16)
The app is for visionOS only - which I'm thinking might be the problem? The share extension is "Designed For iPhone" and requires me to include iPhone as a run destination. In the worst case I can build an iPhone UI for the app but I'd rather not, as it is very specific to visionOS.
Has anyone successfully launched a share extension on a visionOS only app? I have an iPad app with a share extension that shows up fine on visionOS, but the issue seems to be specifically with visionOS only apps.

Hello Community,
I’m currently working with the sample code “CapturingDepthUsingTheLiDARCamera” and using it to capture the depth map of an image taken with the iPhone 14 Pro.
From this depth map, I generate a point cloud using the intrinsic camera parameters.
I've noticed that objects not facing the camera directly appear distorted in the resulting point cloud.
For example: An object with surfaces that are perpendicular to each other appears with a sharper angle in the point cloud — around 60° instead of 90°.
My question is:
Is this due to the general accuracy limitations of the LiDAR sensor? Or could it be related to the sample code?
To obtain the depth map, I’m using:
AVCapturePhoto.depthData.converting(toDepthDataType: kCVPixelFormatType_DepthFloat32)
Thanks in advance for your help!
Hi team I don't know from this error has popped up any suggestions please
Thanks

Hi,
I am in the process of implementing SharePlay into our app. The shared experience opens an Immersive Space and we set systemCoordinator.configuration.supportsGroupImmersiveSpace = true
Now visionOS establishes a shared coordinate space for the immersive space.
From the docs:
To achieve consistent positioning of RealityKit entities across multiple devices in an immersive space during a SharePlay session
There are cases where we want to position content in front of the user (independent of the shared session, and for each user individually). Normally to do that we use the transform retrieved via worldTrackingProvider.queryDeviceAnchor.originFromAnchorTransform
to position content in front of the user (plus some Z Offset and smooth interpolation).
This works fine in non-SharePlay instances and the device transform is where I would expect it to be but during the FaceTime call deviceAnchor.originFromAnchorTransform seems to use the shared origin of the immersive space and then I end up with a transform that might be offset.
Here is a video of the issue in action: https://streamable.com/205r2p
The blue rect is place using AnchorEntity(.head, trackingMode: .continuous). This works regardless of the call and the entity is always placed based on the head position.
The green rect is adjusted on every frame using the transform I get from worldTrackingProvider.queryDeviceAnchor. As you can see it's offset.
Is there any way I can query query this transform locally for the user during a FaceTime call?
Also I would like to know if it's possible to disable this automatic entity transform syncing behavior?
Setting entity.synchronization = nil results in the entity not showing up at all.
https://developer.apple.com/documentation/realitykit/synchronizationcomponent
Is SynchronizationComponent only relevant for the legacy MultiPeerConnectivity approach?
Thank you!
Hi,
after upgrading to 2.4.1 (from 1.0) my vision stucks on "Retrieving configuration" screen. Apple Store didn't support my case since it has been sold in USA and the product isn't still present in italian market. I don't have dev strap, how can I manage the issue?
Thank you

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,
Greetings. I am having this issue with a Unity Polyspatial VisionOS app.
We have our main Bounded Volume for our app.
We have other Native UI windows that appear when we interact with objects in our Bounded Volume.
If a user closes our main Bounded Volume...sometimes it quits the app. Sometimes it doesn't.
If we go back to the home screen and reopen the app, our main Bounded Volume doesn't always appear, and just the Native UI windows we left open are visible. But, we can sometimes still hear sounds that are playing in our Bounded Volume.
What solutions are there to make sure our Bounded Volume always appears when the app is open?
Hello,
In my project, I have attached a ManipulationComponent to Entity A and as expected, I'm able interact with it using the built-in gestures. I have another Entity B which is a child of A that I would like to interact with as well, so I attempted to add a ManipulationComponent to B. However, no gestures seem to be registered on B; I can still interact with A but B cannot be interacted with despite having ManipulationComponents on both entities.
So I'm wondering if I'm just doing something wrong, if this is an issue with the ManipulationComponent, or if this is a limitation of the API.
Attached is the code used to add the ManipulationComponent to an Entity and it was done on both A and B:
let mc = ManipulationComponent()
model.components.set(mc)
var boxShape = ShapeResource.generateBox(width: 0.25, height: 0.05, depth: 0.25)
boxShape = boxShape.offsetBy(translation: simd_float3(0, -0.05, -0.25))
ManipulationComponent.configureEntity(model, collisionShapes: [boxShape])
if var mc = model.components[ManipulationComponent.self] {
mc.releaseBehavior = .stay
mc.dynamics.inertia = .low
model.components.set(mc)
}
I am using visionOS 26.0; let me know if there's any additional information needed.
Since only the user can take a screenshot using the Apple Vision Pro's top buttons, the only workaround available to an immersive app that needs a screenshot to document the user's creative interior design choices is
ask the user to take a screenshot
wait until the user taps a button indicating the screenshot has been taken
then the app asks the user to select the screenshot when the app opens the PhotoPicker
when the user presses Done, the screenshot is handed off to the app.
One wonders why there is no Apple Api for doing this in a simple privacy protective way such as:
When called, the Apple api captures the screenshot in Apple secured memory
The api displays the screenshot to the user with appropriate privacy warnings and asks if the user wants to
a. share this screenshot with the app, or
b. cancel,
c. retake the screenshot
If the user approves, the app receives the screenshot
Here is my code in visionOS 2.3
NavigationSplitView {
List {
}
.navigationTitle("Passwords")
} detail: {
Text("Hello")
.navigationTitle("All")
}
The font size of "Passwords" and "All" are smaller than the ones in Passwords app.
There a way to use contentCaptureProtected with Quick Look on VisionOS 26? Or exist a way to see a spatial photo with Quick Look without sharing options ?
Environment
visionOS 26.1, Xcode 26.1.1
Problem
When a WindowGroup opens an ImmersiveSpace and the user closes the window via X button, the async Task in .onDisappear gets cancelled before dismissImmersiveSpace() completes, leaving the ImmersiveSpace active with no way to exit.
Steps
WindowGroup opens ImmersiveSpace in .onAppear
User clicks X to close window
.onDisappear fires but async cleanup cancelled
ImmersiveSpace remains active, user trapped
Expected
ImmersiveSpace dismissed when window closes
Actual
ImmersiveSpace remains active
Code
.onAppear {
Task {
await openImmersiveSpace(id: "VideoCallMainCamera")
}
}
.onDisappear {
Task {
await dismissImmersiveSpace() // Gets cancelled
}
}
What I've Tried
Task in .onDisappear ❌
scenePhase monitoring ❌
High priority Task ❌
.restorationBehavior(.disabled) + .defaultLaunchBehavior(.suppressed) ✅ (prevents restoration but doesn't fix immediate cleanup)
Question
What's the recommended pattern for ensuring ImmersiveSpace cleanup when WindowGroup closes? Is there a way to block window closure until async cleanup completes, or should ImmersiveSpaces automatically dismiss with their parent window?
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)
In Vision OS app, We 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. 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, and state preservation, 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.
I'm placing sphere at finger tip and updating its position as hand move.
Finger joint tracking functions correctly, but I’ve observed noticeable latency in hand tracking updates whenever a UITextView becomes active. This lag happens intermittently during app usage, lasting about 5–10 seconds, after which the latency disappears and the sphere starts following the finger joints immediately.
When I open the immersive space for the first time, the profiler shows a large performance spike upto 328%. After that, it stabilizes and runs smoothly.
Note: I don’t observe any lag when CPU usage spikes to 300% (upon immersive view load)
yet the lag still occurs even when CPU usage remains below 100%.
I’m using the following code for hand tracking:
private func processHandTrackingUpdates() async {
for await update in handTracking.anchorUpdates {
let handAnchor = update.anchor
if handAnchor.isTracked {
switch handAnchor.chirality {
case .left:
leftHandAnchor = handAnchor
updateHandJoints(for: handAnchor, with: leftHandJointEntities)
case .right:
rightHandAnchor = handAnchor
updateHandJoints(for: handAnchor, with: rightHandJointEntities)
}
} else {
switch handAnchor.chirality {
case .left:
leftHandAnchor = nil
hideAllJoints(in: leftHandJointEntities)
case .right:
rightHandAnchor = nil
hideAllJoints(in: rightHandJointEntities)
}
}
await MainActor.run {
handTrackingData.processNewHandAnchors(
leftHand: self.leftHandAnchor,
rightHand: self.rightHandAnchor
)
}
}
}
And here’s the function I’m using to update the joint positions:
private func updateHandJoints(
for handAnchor: HandAnchor,
with jointEntities: [HandSkeleton.JointName: Entity]
) {
guard handAnchor.isTracked else {
hideAllJoints(in: jointEntities)
return
}
// Check if the little finger tip and intermediate base are both tracked.
if let tipJoint = handAnchor.handSkeleton?.joint(.littleFingerTip),
let intermediateBaseJoint = handAnchor.handSkeleton?.joint(.littleFingerIntermediateTip),
tipJoint.isTracked,
intermediateBaseJoint.isTracked,
let pinkySphere = jointEntities[.littleFingerTip] {
// Convert joint transforms to world space.
let tipTransform = handAnchor.originFromAnchorTransform * tipJoint.anchorFromJointTransform
let intermediateBaseTransform = handAnchor.originFromAnchorTransform * intermediateBaseJoint.anchorFromJointTransform
// Extract positions from the transforms.
let tipPosition = SIMD3<Float>(tipTransform.columns.3.x,
tipTransform.columns.3.y,
tipTransform.columns.3.z)
let intermediateBasePosition = SIMD3<Float>(intermediateBaseTransform.columns.3.x,
intermediateBaseTransform.columns.3.y,
intermediateBaseTransform.columns.3.z)
// Calculate the midpoint.
let midpointPosition = (tipPosition + intermediateBasePosition) / 2.0
// Position the sphere at the midpoint and make it visible.
pinkySphere.isEnabled = true
pinkySphere.transform.translation = midpointPosition
} else {
// If either joint is not tracked, hide the sphere.
jointEntities[.littleFingerTip]?.isEnabled = false
}
// Update the positions of all other hand joint spheres.
for (jointName, entity) in jointEntities {
if jointName == .littleFingerTip {
// Already handled the pinky above.
continue
}
guard let joint = handAnchor.handSkeleton?.joint(jointName),
joint.isTracked else {
entity.isEnabled = false
continue
}
entity.isEnabled = true
let jointTransform = handAnchor.originFromAnchorTransform * joint.anchorFromJointTransform
entity.transform.translation = SIMD3<Float>(jointTransform.columns.3.x,
jointTransform.columns.3.y,
jointTransform.columns.3.z)
}
}
I’ve attached both a profiler trace and a video recording from Vision Pro that clearly demonstrate the issue.
Profiler: https://drive.google.com/file/d/1fDWyGj_fgxud2ngkGH_IVmuH_kO-z0XZ
Vision Pro Recordings:

https://drive.google.com/file/d/1LxTxgudMvWDhOqKVuhc3QaHfY_1x8iA0
Has anyone else experienced this behavior? My thought is that there might be some background calculations happening at the OS level causing this latency. Any guidance would be greatly appreciated.
Thanks!

With the above environment, after installing Apple.PHASE into unity and building to a visionOS device, Audio is available and distance attention works, but Early Reflection and Late Reverb produce no audible change even when checked and their parameters are adjusted.
What is required to make Early Reflection and Late Reverb take effect on a visionOS device build?
action taken
・created a SoundEvent.
・in composer, created a Sampler and a SpatialMixer; attached an AudioClip to the Sampler; enabled Direct Path, Early Reflection, and Late Reverb on the SpatialMixer.
・attached a PHASE Source to the object to be played, attached the created SoundEvent to it, and set non-zero values for Early Reflection and Late Reverb.
・attached a PHASE Listener to the mainCamera and set the ReverbPreset to a value other than None.
・in project settings > Audio, set Spatializer plugin to PHASE Spatializer.
・from there, build for visionOS.
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.
