Extending or disabling the 1.5-meter boundary in ImmersiveSpace
I’m currently developing an app for visionOS and working with an ImmersiveSpace. I’ve noticed that the system automatically enforces a safety boundary at approximately 1.5 meters. If the user moves beyond this limit, the content fades out or the system reverts to Passthrough. Is there any way to disable this boundary or extend its radius? This app is currently in the experimental/verification phase, and it is intended to be run on a Vision Pro in Developer Mode. Since the primary goal is to test large-scale spatial interactions during development, I am looking for any way—including developer-specific settings or configurations—to bypass or expand this limit. If there isn't a direct API to change the boundary size, are there any recommended workarounds for testing movement within large environments? Any insights would be greatly appreciated!

Low-latency live streaming using APMP Wide FoV
Is it possible to achieve sub-second end-to-end latency when displaying live streaming video using APMP (Apple Projected Media Profile) with Wide FoV? APMP supports HLS playback, but my understanding is that standard HLS introduces several seconds of latency. I would like to know whether APMP (especially Wide FoV) supports Low-Latency HLS, or if there are inherent limitations that make sub-second latency impractical. If APMP is not suitable for this use case, are there any recommended alternatives within AVFoundation or related frameworks for rendering wide-FoV live video with very low latency? Thank you for any insights.

With manipulation component, once you let go, how to prevent the entity from disappearing while animating it back into the volume
So with the new ManipulationComponent, we can choose "stay" and then if you drag it out of your volume, once you let go it will instantly disappear. We can "animate" it back to inside the volume, eg.: content.subscribe(to: ManipulationEvents.WillRelease.self) { event in Entity.animate( .easeInOut(duration: 1), body: { event.entity.position = [0, 0.2, 0] }, completion: {} ) }, Howeve,r for the duration that it travels outside of the volume it's invisible the whole time. In this apple video, it seems to be visible when dragging and when letting go, but perhaps that's not a volume they're dragging it out of? https://youtu.be/VtenPKrvPOU?si=y1zoZOs2IMyDzOm6&t=1748 Does anyone know how to keep the entity visible even when after letting the entity go while you animate it back towards inside of your volume?

How to Renew visionOS Enterprise API Entitlements?
How can I renew visionOS Enterprise API? I've spent so much time contacting Apple Developer Support. They said they don't know the renewal process either and are "checking with the internal operations team" - but it's been 2 months with no updates. The official documentation (https://developer.apple.com/documentation/visionOS/building-spatial-experiences-for-business-apps-with-enterprise-apis#Request-the-entitlements) says: "The license file comes with an expiration date, so you need to renew it before then to ensure your entitlements continue to function." But it doesn't explain HOW to renew. When I asked Apple Support about this, they told me: "After Apple approves your app for one or more entitlements, you receive a license file, along with additional instructions." But I never received any instructions when I was first approved, and I still don't know how to renew. There's also no direct way to contact the Enterprise API team. Now my visionOS Enterprise API license has been expired for 2 months. I submitted a renewal request, but I still haven't heard anything back. Is it normal to take more than 2 months for approval? Any advice or shared experiences would be really helpful. Thanks!

onWorldRecenter memory leak and duplicate callbacks in ImmersiveSpace
Posting this here in case this information is helpful to other developers: As of visionOS 26.3 beta 1, onWorldRecenter has two significant issues: (FB21557639) Memory Leak: When onWorldRecenter is assigned to a RealityView within an ImmersiveSpace, it appears to retain a strong reference to the view's internal SwiftUI context. When the immersive space is dismissed, the view's @State objects will not be deallocated. Also, each time the immersive space view's body is executed, additional state storage will be allocated and leaked. Multiple Callbacks: When the user long-presses the Digital Crown, the onWorldRecenter closure will be called multiple times, once for each past view body execution, including those of immersive space views that have been previously dismissed. Although these issues seem to be most prevalent when onWorldRecenter is used with an ImmersiveSpace, they may also occur in the context of a WindowGroup under certain circumstances. It's possible to work around this problem by moving onWorldRecenter to an empty overlay view within the app's primary WindowGroup and forwarding the world recenter events to ImmersiveSpace views through a notification system, coupled with a debouncer as an extra precaution.

Displaying spatial photos and videos on web pages in Safari
The purpose is to create a simple web-based gallery of spatial photos and videos using static html files. I have successfully displayed spatial photos using the img tag and IMG.heic files. I can tap and hold the image to bring up the contextual menu and from there select View Spatial Photo. Is there any way to add a control to the image, like a link or overlay on the image itself, that a user can simply tap to show the image in 3D? And how to host a video file on a web page without going through a CDN/streaming service? Sample html would be much appreciated.

fileImporter issue in visionOS with iPhone app (that can run on visionOS)
Happy new year to all! I have created an iOS app that also runs on Apple Vision Pro. On iOS, when you activate the fileImporter modal, you can swipe down the modal in iOS to dismiss. However, in visionOS, this same modal CANNOT be swiped down to cancel/dismiss. If you are drilled deep into a file hierarchy, you have to navigate back to the top level to tap X to dismiss. Is there a way to add swipe down to the visionOS implementation of fileImporter, or any other workaround so the user doesn't have to navigate back to the top to dismiss? Again, this is not a visionOS app but an iOS app compatible for use in Vision Pro. Thanks!

Building a Full Space app that enables sharing a visionOS experience with nearby users.
Hello, I am currently considering developing a Full Space app that enables a shared visionOS experience with nearby users. Intended Features A Mixed Full Space app in which dozens of 3D models are placed in the space. These 3D models may play embedded animations when tapped, be programmatically moved or rotated, or be controlled via Reality Composer Pro timelines. The app also includes audio, spatial audio, videos with audio, and videos without audio, which are rendered as VideoTextures on planes and played back in the space. Some media elements play automatically, while others are triggered by user interaction. However, it is unclear whether AVPlaybackCoordinator supports shared playback across multiple types of media, such as: audio only spatial audio video without audio video with audio I am also unsure whether there are alternative or recommended approaches for synchronizing playback in this scenario. Questions Is it technically possible to implement the experience described above using visionOS? Are there any important implementation considerations or limitations that should be taken into account? For example, when two participants experience the app simultaneously, how is the content positioned for each participant? Is the spatial placement of content shared across participants, or is it positioned relative to each participant’s viewpoint? For nearby participants, is it necessary to register a spatial Persona? My understanding is that spatial Personas are not visible for nearby users during the experience; is this correct? When experiencing SharePlay with nearby users, is it possible to share the experience without registering the other participant’s contact information? I have watched the following session, but I was unable to fully understand the feasibility of the above use case or the concrete implementation details: https://developer.apple.com/videos/play/wwdc2025/318/ Thank you.

Implementing Foveated Streaming with Apple Vision Pro
Hello, Want to understand what's the current state for developing for Apple Vision Pro? I want to stream a video from a remote server in realtime. It is a video stream and can't download it. I want to stream a low quality stream and high res stream. The server will only send the "box" where user is looking at. Are there any API to track where the user is looking at in the experience? Thanks,

Real Time Spatial Video Streaming with Vision Pro
Hello, I am trying to build an AVP app for real-time "zero-latency" spatial video streaming. I am trying to figure out, on a high level, the best way to do this. Currently this is my method: Server sends stereo images via a WebRTC service (ie, livekit) The WebRTC stream is converted to a CVPixelBuffer, writes them to file, plays via AVPlayer, and applies a VideoMaterial to a plane entity. However, this is a bit hacky and it seems like this won't be compatible with Apple's spatial experinces. To my understanding, Apple supports HLS streaming for spatial experiences and APMP content. However, HLS (and even Low Latency HLS) introduces a second or more of latency, likely do to the segmentation nature of HLS. Thus, HLS will not work for us. Some other alternatives I've thought of are streaming the live stream video via webrtc from the server to a local computer in the AVP's network, and then using LL-HLS to stream from the local computer to the vision pro. Still, it seems like this would introduce latency on the order of seconds. Is my current approach the best way to implement this? Or could anyone suggest a better way, perhaps something compatible with AVP's spatial experiences

How to fix "Sample 0 missing LiDAR point cloud!" error?
I'm trying to run a PhotogrammetrySession based on photos taken in an AVCaptureSession and stored as .heic files. When I load the files I'm always seeing the error "Sample 0 missing LiDAR point cloud!" showing up for each individual sample. Debugging shows that sample.depthDataMap is populated, also the .heic contains depth data which can be extracted using e.g. heif-convert on my Mac. Comparing the .heic I created to one of the ObjectCaptureSession which doesn't show the LiDAR warning, I noticed the only difference being the HEIC information here: So my questions are: Are these the missing information in my manual capture causing this warning? Can I somehow add these information in an AVCaptureSession? Do these information allow better photogrammetry results?
