How can I request access to Enterprise API for VisionPro with an individual developer account? I wanted it for learning and testing

Hey everyone, I'm working on an object viewer where users can place objects in a real room using AR, and I want both visionOS (Apple Vision Pro) and iOS devices (iPad, iPhone) to participate in the same shared spatial experience. The idea is that a user with a Vision Pro can place an object, and peers using iPhones/iPads can see the same object in the same position in their AR view. I've looked into ARKit's Shared ARWorldMap and MultipeerConnectivity, but I'm not sure if this extends seamlessly to visionOS or if Apple has an official way to sync spatial data between visionOS and iOS devices. Has anyone tried sharing a spatial world between visionOS and iOS? Are there any built-in frameworks that allow for a shared multiuser AR session across these devices? If not, what would be the best way to sync object positions between them? Would love to hear if anyone has insights or experience with this! 🚀 Thanks!

I recently added pushWindow to my app, and I discovered that in visionOS 26.2 RC (23N301), pushWindow followed by dismissWindow no longer works as expected. Specifically, if the user moves the pushed window, then when the pushed window is later dismissed, the parent window's position isn't aligned with the pushed window's new position. Its original position is restored instead. Curiously, the bug only happens when an app is launched from the visionOS home view, and not when an app is launched from Xcode. It also doesn't happen in the visionOS 26.2 simulator. Another interesting detail is that while the parent window is hidden, if the user long-presses the Digital Crown and then dismisses the pushed window, the parent window's position seems to be immune from the Digital Crown scene reorientation. It's restored to its original real world position. Demo video: https://youtu.be/zR3t2ON3Wz0 I've submitted feedback as FB21287011 with a sample app and detailed repro steps. Has anyone else encountered this issue already and figured out a workaround? It would be nice if I could get pushWindow to work correctly in my app. Thanks everybody! 😀

I posted https://developer.apple.com/forums/thread/809481 yesterday about an issue I discovered with pushWindow in visionOS 26.2 RC, but today I discovered a second problem with pushWindow. If window A calls pushWindow to present window B, and the user pins window B to a wall, the following unexpected behaviors are observed: Window B spontaneously disappears. If the user re-launches the (still running) app from the visionOS home view, both window A and window B appear simultaneously. I assume only window B should be visible at this point, since window A pushed window B. If the user closes window B, it's now impossible to present window B again. Calls to pushWindow appear to be ignored. If the user force-quits the app and relaunches it, and pushWindow is called again, window B appears, but window A remains visible. I also noticed this surprising behavior: This broken state of pushWindow behavior now affects all other apps on the system that may call pushWindow in the future, not just the app whose pushed window was pinned above. A workaround is to reboot the device, and then the system will behave as expected until the next time the user pins a pushed window.

I am using Entity of RealityKit to display virtual content, however I find that sometimes the real object in front of the virtual content can not occulude the virtual content. For example, I place an Entity in a room, but when I walk into another room, I can still see the Entity through the wall. I wonder how should I fix the problem. Thank you!

I am developing an ARKit based application that requires plane detection of the tabletop at which the user is seated. Early testing was with an iPhone 8 and iPhone 8+. With those devices, ARKit rapidly detected the plane of the tabletop when it was only 8 to 10 inches away. Using iPhone 15 with the same code, it seems to require me to move the phone more like 15 to 16 inches away before detecting the plane of the table. This is an awkward motion for a user seated at a table. To validate that it was not necessarily a feature of my code, I determined that the same behavior results with Apple's sample AR Interaction application. Has anyone else experienced this, and if so, have suggestions to improve the situation?

Hi, I am creating an ECS. With this ECS I will need to register several DragGesture. Question: Is it possible to define DragGestures in ECS? If yes, how do we do that? If not, what is the best way to do that? Question: Is there a "gesture" method that takes an array of gestures as a parameter? I am interested in any information that can help me, if possible with an example of code. Regards Tof

Hi, we've been through the Explore Object Tracking for visionOS and worked through the sample code ExploringObjectTrackingWithARKit. What we'd really like to see is Object Tracking for iOS using devices with either LiDAR or the TrueDepth/RGB cameras.

Hi, I'm playing now with hand tracking. I want to get position of hand inside a system update function. I was not sure if transform I'm getting from hand attached AnchorEntity (with trackingMode: .predicted) would give same results as handAnchors(at:) from hand tracking provider, so I started to read them both and compare. For handAnchors i tried using context.scene.timebase.sourceTimebase!.sourceClock!.time.seconds and CACurrentMediaTime() as timestamp source. They seem to use exactly same clock, so that doesn't matter, but: for some reason update handler is always called twice with same context.deltaTime, but first time the query finds 0 entities, second time it finds them all. The query is the standard EntityQuery(where: .has(MyComponent.self)) and in update (matching: Self.query, updatingSystemWhen: .rendering). Here's part of logs: System update called, entity count: 0, dt: 0.01000458374619484, absTime: 4654.222593541 System update called, entity count: 11, dt: 0.01000458374619484, absTime: 4654.22262525 System update called, entity count: 0, dt: 0.009999999776482582, absTime: 4654.249390875 System update called, entity count: 11, dt: 0.009999999776482582, absTime: 4654.249425 accounting for the double update calling I started to calculate time delta of absolute time between calls and they're most of the time much bigger, or much smaller than advertised by system's context.deltaTime, only sometimes they kind of match, for example: system: (dt: 0.01000458374619484) scene : (dt: 0.021419291667371) (absTime: 4654.222628125001) and the very next call system: (dt: 0.010009 166784584522) scene : (dt: 0.0013097083328830195) (absTime: 4654.223937833334) but sometimes system: (dt: 0.009999999776482582) scene : (dt: 0.009 112249999816413) (absTime: 4654.351299 166668) Shouldn't those be more or less equal, or am I missing something? In the end it seems that getting hand position from AnchorEntity and with handAnchors(at:) gives kind of same results, but at different time points, so I'd love to understand what's the correct way to use them and why time flows differently :). --Edit-- P.S. Had to put spaces everywhere in logs between "9" and "1", otherwise post was blocked due to "sensitive content" :D

https://developer.apple.com/documentation/realitykit/videomaterial The documentation: "Video materials support transparency if the source video’s file format also supports transparency." I have a transparency video(Hand.mov, HEVC with alpha), I can show the video with transparency background correctly on Vision Pro Simulates, but on physic Device the video has a black background. I'm sure the video format is ok because I can see get the texture from video and display it on an UnlitMaterial. How can I show the transparency video correctly with the RealityKit/VideoMaterial?

Hello, I have downloaded and run the sample object tracking app for visionos. Now I'm working on my own objects for tracking. I have made a model using Create ML using images of my object. However, I cannot see how to convert the Create ML output file (xxx.mlmodel) into a reference object like the files in the sample project. is there a tool for converting them? TIA

Hello, Let me ask you a question about Apple Immersive Video. https://www.apple.com/newsroom/2024/07/new-apple-immersive-video-series-and-films-premiere-on-vision-pro/ I am currently considering implementing a feature to play Apple Immersive Video as a background scene in the app I developed, using 3DCG-created content converted into Apple Immersive Video format. First, I would like to know if it is possible to integrate Apple Immersive Video into an app. Could you provide information about the required software and the integration process for incorporating Apple Immersive Video into an app? It would be great if you could also share any helpful website resources. I am considering creating Apple Immersive Video content and would like to know about the necessary equipment and software for producing both live-action footage and 3DCG animation videos. As I mentioned earlier, I’m planning to play Apple Immersive Video as a background in the app. In doing so, I would also like to place some 3D models as RealityKit entities and spatial audio elements. I’m also planning to develop the visionOS app as a Full Space Mixed experience. Is it possible to have an immersive viewing experience with Apple Immersive Video in Full Space Mixed mode? Does Apple Immersive Video support Full Space Mixed? I’ve asked several questions, and that’s all for now. Thank you in advance!

Error: RoomCaptureSession.CaptureError.exceedSceneSizeLimit Apple Documentation Explanation: An error that indicates when the scene size grows past the framework’s limitations. Issue: This error is popping up in my iPhone 14 Pro (128 GB) after a few roomplan scans are done. This error shows up even if the room size is small. It occurs immediately after I start the RoomCaptureSession after the relocalisation of previous AR session (in world tracking configuration). I am having trouble understanding exactly why this error shows and how to debug/solve it. Does anyone have any idea on how to approach to this issue?

i'd like to have a little bit control over the transparency of the videomaterial. is there any way to prepare a shadergraph unlit shader and use it with the videomaterial.

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

My app is getting video from UVC device, and I wish to display it in an Immersive Space. But when I open Immersive Space, the UVC capture will just stop.AI said it's due to confliction in Camera pipeline. But I don't really understand, I don't need to use any on device camera, why it conflict with my UVC...

Using the example code posted here: https://developer.apple.com/documentation/visionOS/tracking-images-in-3d-space I can register multiple ReferenceImage s with a ImageTrackingProvider, but only one updates at a time - to have realtime updating, I can only have one ImageAnchor in my field of view at a time. Is it possible to track multiple imageAnchors at the same time in the same field of view? As in having several ImageAnchor's tracked and entities updated to the transforms of the anchor in the same frame/moment from the Apple Vision Pro?

Hi I know it's possible to play equirectangular VR180 video either SBS or MV-HEVC. And for fisheye video, the only way I know is to convert it into an AIVU for playback. Is there any way to directly play fisheye video using AVPlayer? Thanks a lot!
