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.

Hi everyone, I'm developing a MR Vision Pro app where I’d like to anchor virtual objects (such as UI elements) around the user's arm. However, I’ve noticed that Vision Pro seems to mask out the area where the user’s real arm is, hiding virtual content in that region so that you see your real arm.
Is there a way to render virtual elements on the user's arm—so that it looks like the object is placed directly on the arm despite the real-world passthrough? I was hoping there might be a way to adjust the depth or behavior of this masked-out region. Any insights or workarounds would be greatly appreciated! Thanks :)
I noticed in the latest macOS beta 3 that there was this update:
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)
I am not noticing any difference to before with the reconstructions I tested so I am assuming it's reverting to the old model but in the logs there is no way to see if it succeeds or fails to download that new model.
do you have any more information on what was improved here with some examples and what we should be looking for? also how can confirm the download of that new model has not failed?
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?
I'm working on a project that uses imageTrackingProvider through ARKit on VisionPro, and I want to detect multiple images(about 5) and show info at the same time.
However, I found that it seems only 1 image could be detected by device at one time.
And the api of maximumNumberOfTrackedImages doing this seems not available for visionOS but only iOS.
Anyone knows possible ways to detect multiple images at the same time on VisionPro?

Seeing this magical sand table, the unfolding and folding effects are similar to spreading out cards, which is very interesting. But I don't know how to achieve it. I want to see if there are any ways to achieve this effect and give some ideas. May I ask if this effect can be achieved under the existing API
I have tested the MagnifyGesture code below on multiple devices:
Vision Pro - working
iPhone - working
iPad - working
macOS - not working
In Reality Composer Pro, I have also added the below components to the test model entity:
Input Target
Collision
For macOS, I tried the touchpad pinch gesture and mouse scroll wheel, but neither approach works. How to resolve this issue? Thank you.

import RealityKit
import RealityKitContent
struct ContentView: View {
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)
}
}
.gesture(MagnifyGesture()
.targetedToAnyEntity()
.onChanged(onMagnifyChanged)
.onEnded(onMagnifyEnded))
}

}
func onMagnifyEnded(_ value: EntityTargetValue<MagnifyGesture.Value>) {
print("onMagnifyEnded")

Currently I am using mixed style immersive view to place both my WindowView(plain style) and ImmersiveView content together. The issue is that the rendering depth testing may always let the virtual content block my normal WindowView. Is it possible to manually set windowedVIew always displays in the front of my virtual view in mixed style immersion? (I know modelSortGroup but it doesn't quite fits here)
Or if I can dynamically change the .progressive value when the immersive space is open (set the value to zero means .mixed itself right?)
In a simple test, I'm observing ~30% higher CPU usage with the ARWorldTrackingConfiguration compared to the ARBodyTrackingConfiguration when both configurations have AREnvironmentTexturing enabled.
In Instruments, I observe Recon3D consuming ~5.5 seconds of CPU time with the ARWorldTrackingConfiguration vs <0.3 second with the ARBodyTrackingConfiguration in two separate 30 seconds samples.
This is on an iPhone 12 Pro equipped with lidar.
Is there a reason why two separate configurations, both having the same features enabled would have a different CPU overhead?
I am developing an app in VisionPro using RealityKit and ARKit. I want my RealityKit entity looks more realistic. So it is important to render its shadow based on light in real world.
e.g. When I turn on the light in real world, the shadow of the entity will change. Can this effect be implemented in VisionPro?
After updating to the latest visionOS beta, visionOS 26 Beta 4 (23M5300g) the ‘Presenting images in RealityKit’ sample from the following link no longer builds due to an error. https://developer.apple.com/documentation/RealityKit/presenting-images-in-realitykit
Expected / Previous:
Application builds and runs on device, working as described in the documentation.
Reality:
Application builds, but does not run on device due to an error (shown in screenshot) “Thread 1: EXC_BAD_ACCESS (code=1, address=0xb)”. The application still runs on the simulator, but not on device. When launching the app from Xcode, it builds and installs correctly but hangs due to the respective error. When loading the app from the Home Screen, the app does not load, and immediately returns to the Home Screen.
This Xcode project previously ran with no changes to code - the only change was updating the visionOS system software to the latest version. visionOS 26 Beta 4 (23M5300g)
Is anyone else experiencing this issue?
It's much easier to use custom material to bridge metal shader onto Reality model than using LowLevelTexture does the same thing.
Why VisionOS doesn't support this material:
I have a visionOS 2 project created on Xcode 16, when I updated to Xcode 26 beta5, I can't build it any more, every time it stuck in process like the picture shows below:
Already tried many methods to fix this issue, such as clear build folders, but don't work.

help me please i cant remove little messed up pixels and they are getting more and more please help me!!

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"?

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've tried following apple's documentation to apply a video material on a Model Entity, but I have encountered a compile error while attempting to specify the Spatial Audio type.
It is a 360 video on a Sphere which plays just fine, but the audio is too quiet compared to the volume I get when I preview the video on Xcode. So I tried tried to configure audio playback mode on the material but it gives me a compile error:
"audioInputMode' is unavailable in visionOS
audioInputMode' has been explicitly marked unavailable here
RealityFoundation.VideoPlaybackController.audioInputMode)"
https://developer.apple.com/documentation/realitykit/videomaterial/
Code:
let player = AVPlayer(url: url)
// Instantiate and configure the video material.
let material = VideoMaterial(avPlayer: player)
// Configure audio playback mode.
material.controller.audioInputMode = .spatial // this line won’t compile.
VisionOS 2.4, Xcode 16.4, also tried Xcode 26 beta 2.
The videos are HEVC MPEG-4 codecs.
Is there any other way to do this, or is there a workaround available?
Thank you.
According to the official documentation, the .blur(radius:) modifier could apply gaussian blur to a realityview. However, when applied directly to a RealityView, nothing inside it (neither 2D attachments nor 3D entities) appears to be blurred.
Here’s the test code:
struct ContentView: View {
var body: some View {
VStack(spacing: 20) {
Text("Above the RealityView")
.font(.title)
RealityView { content, attachments in
if let text = attachments.entity(for: "2dView") {
text.position.y = 0.1
content.add(text)
}
let box = ModelEntity(
mesh: .generateBox(size: 0.1),
materials: [SimpleMaterial(color: .red, isMetallic: true)]
)
content.add(box)
} attachments: {
Attachment(id: "2dView") {
Text("Above the Box")
.font(.title)
}
}
.frame(width: 300, height: 300)
.border(.blue)
.blur(radius: 99) // Has no visual effect
Text("Below the RealityView")
.font(.subheadline)
}
.padding()
}
}
My question:
How can I make .blur(radius:) visually affect the content rendered in a RealityView?
Can you provide a working example that .blur() to visually affect any part of a RealityView?
Thanks!
I want to select a sub model under a large model in a mixed space, and when I select this sub model, I will add a stroke to it, similar to the effect of selecting a model in Reality Composer Pro ,How to create entity strokes similar to this effect
In my Reality Composer Pro workflow for Vision Pro development, I’m using xcrun realitytool image to pre-compress textures into .ktx format, typically using ASTC block compression. These textures are used for cubemaps and environment assets.
I’ve noticed that regardless of the image content—whether it’s a highly detailed photo or a completely black image—once compressed with the same ASTC block size (e.g., ASTC_8x8), the resulting .ktx file size is nearly identical. There appears to be no content-aware logic that adapts the compression ratio to the actual texture complexity.
In contrast, Unreal Engine behaves differently: even when all cubemap faces are imported at the same resolution as DDS textures, the engine performs content-aware compression during packaging:
Low-complexity images are compressed more aggressively
The final packaged file size varies based on content complexity
Since Reality Composer Pro requires textures to be pre-compressed as .ktx, there’s no opportunity for runtime optimization or per-image compression adjustment.
Just wondering: is there any recommended way to implement content-aware compression for .ktx textures in Reality Composer Pro?
Or any best practices to optimize .ktx sizes based on image complexity?
Thanks!
