it looks like one week after accepting as a nearby other AVP device... it expires
since we are providing our clients for a timeless app to walk inside archtiecture, it's a shame that not technical staff should connect every week 5 devices to work together
is there any roundabout for this issue or straight to the wishlist ?
thanks for the support !!

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.
I am running a Spatial Rendering App template demo, it shows “No People Found ” “There is no one nearby to share with”.
How can I stream videos rendered by Mac to my vision pro
I am using macOS 26.0, visionOS 26, Xcode 26

Hi everyone,
I'm creating an educational App that allows doing computational design in an immersive environment with the Vision Pro. The App is free and can be found here:
https://apps.apple.com/us/app/arcade-topology/id6742103633
The problem I have is that the mesh of voxels I currently create use ModelEntity and I recently read that this is horrible for scalability. I already start to see issues when I try to use thousands of voxels. I also read somewhere that I should then take advantage of GPUs and use metal to that end. I was wondering if someone could point me to a tutorial or article that discusses this. In essence, I need to create a 3D voxel mesh, and those voxels have to update their opacity within an iterative loop.
Thanks!

When building a multiplayer Tabletop game, the documentation includes how to attach a custom TabletopNetworkSessionCoordinator, which could be used in addition to TabletopGame.MultiplayerDelegate. But so far, we have been unable to create these types of custom coordinators or have a delegate that works.
Our current setup with our generic GroupActivity works by sending the session to TabletopGame's coordinateWithSession method (like in the current sample project), but we didn't find a way to access and control, for example, the arbiter, seats, player events, among other features mentioned on https://developer.apple.com/documentation/tabletopkit/tabletopnetworksession.
Is correct to expect having access to the participants, messenger, or journal without having to maintain a parallel coordinator?
possibly we are missing something here; any suggestions?
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.
I am creating a vision pro app with a 3D model, it has a mesh hierarchy of head, hands, feet etc. I want the character to look towards the camera, but am not able to access head of character through sceneKit nor reality kit. when I try to print names of the child meshes, it only prints till the character, it does iterate through all the body parts. Can anyone help?
This is no longer highlighting my entity when looking at it:
RealityView { content
let hoverComponent = HoverEffectComponent(.spotlight(
HoverEffectComponent.SpotlightHoverEffectStyle(
color: .white, strength: 2.0
)
))
entity.components.set(hoverComponent)
The entity is in a window. The same code works in an immersive view.
Collision Component and Input type are set in RCP.
It's also stopped working on my published app (built under visionOS 2.x) using my visionOS 26 device.
If I use a 2.x simulator, it works.
Is this a bug or is there something I'm missing?
Thanks.
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:
Hi!
I'm currently trying to render another XR scene in front of a RealityKit one.
Actually, I'm anchoring a plane to the head with a shader to display for left/right eye side-by-side images. By default, the camera has a near plane so I can directly draw at z=0.
Is there a way to change the camera near plane? Or maybe there is a better solution to overlay image/texture for left/right eyes?
Ideally, I would layer some kind of CompositorLayer on RealityKit, but that's sadly not possible from what I know.
Thanks in advance and have a good day!
Hello,
I am currently working on a Unity project for the Apple Vision Pro. I would like to have people passing in front of the virtual objects occlude the virtual objects that are behind. Something similar to this: https://developer.apple.com/documentation/arkit/occluding-virtual-content-with-people
I could unfortunately not find any documentation about this. Is it possible to implement body segmentation or occlusion on the Apple Vision Pro? If it's not currently supported, are there plans to add it? Any ideas on how to achieve this with existing tools?
Thanks!

While using Screen Mirroring in developer mode within my immersive space, I noticed an alignment issue with the computer cursor (transparent circle). When I move it toward an attachment view, the cursor remains horizontal instead of aligning with the surface of the attachment view. It shows correctly on a 2D window only wrong on attachment view.
Is this behavior a bug, or could it be caused by a missing or incorrect configuration on the attachment view?
Want help, thanks.
I'm using Unity 2022.3.56f, with Apple VisionOS App Mode set to 'Virtual Reality - Fully Immersive Space'.
It seems that the render resolution of my game in the Apple Vision Pro when I build is well below the native resolution of the AVP displays.
I can't see a setting in XR Plug-in Management Apple visionOS options, or in Quality settings, to increase the render resolutions. Is this possible?
I tried setting:
UnityEngine.XR.XRSettings.eyeTextureResolutionScale= 2.0f
For example, but this doesn't seem to do anything to the render resolution in the build.

Can we constrain or clamp translation with the new ManipulationComponent? For example, allow free movement within certain bounds.
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

Hello,
There are three issues I am running into with a default template project + additional minimal code changes:
the Sphere_Left entity always overlaps the Sphere_Right entity.
when I release the Sphere_Left entity, it does not remain sticking to the Sphere_Right entity
when I release the Sphere_Left entity, it distances itself from the Sphere_Right entity
When I manipulate the Sphere_Right entity, these above 3 issues do not occur: I get a correct and expected behavior.
These issues are simple to replicate:
Create a new project in XCode
Choose visionOS -> App, then click Next
Name your project, and leave all other options as defaults: Initial Scene: Window, Immersive Space Renderer: RealityKit, Immersive Space: Mixed, then click Next
Save you project anywhere...
Replace the entire ImmersiveView.swift file with the below code.
Run.
Try to manipulate the left sphere, you should get the same issues I mentioned above
If you restart the project, and manipulate only the right sphere, you should get the correct expected behaviors, and no issues.
I am running this in macOS 26, XCode 26, on visionOS 26, all released lately.

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

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.
