On Xcode 26 and visionOS 26, apple provides observable property for Entity, so we can easily interact with Entity between RealityScene and SwiftUI, but there is a issue: It's fine to observe Entity's position and scale properties in Slider, but can't observe orientation properties in Slider.

Dear all, I´m using Unity 6.2 beta and Xcode 16.2. I´m creating a simple framework to use the text to speech functionality in VisionOS from unity. The framework is created in Swift. I create an objective-c wrapper with the following declarations: ... void _initTTS(int); ... I create the framework, import it in Unity and call the functions in a c# wrapper class. The code is as follows: public static class TTSPluginManager { [DllImport("TTS_Vision"] private static extern void _initTTS(int val); ... public static void Initialize() { #if UNITY_VISIONOS _initTTS(0); #else Debug.LogWarning("NativeTTS.Initialize called on a non-iOS platform. Ignoring."); #endif } } I have managed to compile and run the program in the Apple Vision Pro, but I keep on getting the following error: DllNotFoundException: TTS_Vision assembly: type: member:(null) TTSPluginManager.Initialize () (at Assets/Plugins/TTSPluginManager.cs:33) LecturePortalManager.OnCreateStory (Ink.Runtime.Story story) (at Assets/AVRLecture/LecturePortalManager.cs:17) InkLoader.StartStory () (at Assets/AVRLecture/InkLoader.cs:24) InkLoader.Start () (at Assets/AVRLecture/InkLoader.cs:18) If I run the generated code from Xcode, I can see the app in the AVP, but I keep getting a loading error: DllNotFoundException: Unable to load DLL 'TTS_Vision'. Tried the load the following dynamic libraries: Unable to load dynamic library '/TTS_Vision' because of 'Failed to open the requested dynamic library (0x06000000) dlerror() = dlopen(/TTS_Vision, 0x0005): tried: '/TTS_Vision' (no such file) at TTSPluginManager.Initialize () [0x00000] in <00000000000000000000000000000000>:0 at LecturePortalManager.OnCreateStory (Ink.Runtime.Story story) [0x00000] in <00000000000000000000000000000000>:0 I can see in the generated code that the framework (TTS_Vision) is there, but the path seems wrong. I've tried to add more options to the searched paths, with no success... Any hints or suggestions are much more appreciated.

Any way to extend the video recording time in Reality Composer Pro from 3:00 to any longer value, such as editing preferences in Terminal or other workaround? Is there any way to use the strap and a USB-C cable as a live video stream input source that would mirror to Quicktime or some other video capture tool? I am assuming there is no online documentation or user manual for the strap, but please correct me if I'm wrong. Thank you.

I am working on an app that will allow a user to load and share their model files (usdz, usda, usdc). I'm looking at security options to prevent bad actors. Are there security or validation methods built into ARKit/RealityKit/CloudKit when loading models or saving them on the cloud? I want to ensure no one can inject any sort of exploit through these file types.

I'm playing about with the hand tracking systems in reality kit / Vision Pro I thought it would be interesting if I could attach a virtual object to a hand when the hand is gripping (thought it would be fun to attach a basic cylinder to mimic a wand from Harry Potter) I'm able to detect when the user is gripping but having trouble placing an object as though it's within the hand. The simplest version of this is using an AnchorEntity pointing to the user's palm which kind of works, but quickly breaks the illusion when you rotate the wrist or hand. It seems as though I will have to roll my own anchor entity using the various points of the user's hand and I thought calculating some median point between the thumb and little finger tips would be a good start but it's proven a little difficult as we need both rotation and position. I'm already out of my depth with reality kit and matrices (and thanks to ChatGPT) I have some code, but as soon as I apply the position manually (as opposed to a hand anchor entity) it fails to render on the user's hand. It feels like this should already have been something someone has looked in to, any ideas on what might be the issue here? Note: HandTrackingSystem.handTracking is a HandTrackingProvider() guard let anchors = HandTrackingSystem.handTracking.latestAnchors.leftHand else { return } if let thumb = anchors.handSkeleton?.joint(.thumbTip), let little = anchors.handSkeleton?.joint(.littleFingerTip) { let thumbPos = simd_make_float3(thumb.anchorFromJointTransform.columns.3) let littlePos = simd_make_float3(little.anchorFromJointTransform.columns.3) let midPos = (thumbPos + littlePos) / 2 let direction = normalize(littlePos - thumbPos) let rotation = simd_quatf(from: [0, 1, 0], to: direction) wandEntity.transform.translation = midPos wandEntity.transform.rotation = rotation content.add(wandEntity) }

Can I apply .scrollInputBehavior(.enabled, for: .look) to a WebView (wrapped UIViewRepresentable) in a visionOS 26 app? I tried it myself, but I couldn't do it, so I would like to know if there is any way to do this. Best regards.

I developed an app on VisionPro and created a button that allows users to exit the app instead of being forced to exit. I use the ”exit (0)“ scheme to exit the application, but when I re-enter, the loaded window is not the initial window, so is there any relevant code that can be used? Thank you

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!

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.

Hello! I'm a developer of Ping Pong for Apple Vision Pro (Ping Pong Club). I'm experiencing an issues with collisions between ball and paddle. Sometimes the ball just unexpectedly flying away like it has been hit to hard. I believe this is happening because hand anchors are jittering (ping pong paddle has hand anchor component) and at the time of collision unnecessary micro motion produced. I've build a demo app to demonstrate that: https://drive.google.com/file/d/1gBh-DsXuVZdvDrrD7gJcbJ_hg7tvVKUV/view?usp=share_link Video: https://drive.google.com/file/d/1poPbsJdBz87edqrWIfBt1eSVzfm5CTek/view?usp=sharing Is there a way to add some threshold to prevent jittering?

Previously I had developed software using SMI eye trackers, both screen mounted and their mobile glasses, for unique therapeutic and physiology applications. Sadly, after SMI was bought by Apple, their hardware and software have been taken off the market and now it is very difficult to get secondhand-market systems. The Apple Vision Pro integrates the SMI hardware. While I can use ARKit to get gaze position, I do not see a way to access information that was previously made accessible on the SMI hardware, particularly: dwell time and pupil diameter information. I am hopeful (or asking) to see that if a user has a properly set up Optic ID and would opt-in if, either on the present or a future version of visionOS, it might be possible to get access to the data streams for dwell times and pupil diameter. Pupil diameter is particularly important as it is a very good physiological measure of how much stress a person is encountering, which is critical to some of the therapeutic applications that formerly we used SMI hardware. Any ideas, or, if this is not possible, proposing this to the visionOS team would be appreciated!

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?

Since using Quick Look exits you from both your app and Immersive Space. Is there a way to view immersive images within Immersive Space?

I have a scene that has been assembled in RCP but I'm losing the correct hierarchy and transforms when running the scene in the headset or the simulator. This is in RCP: This is at runtime with the debugger: As you can see the "MAIN_WAGON" entity is gone and part of the hierarchy are now children of "TRAIN_ROOT" instead. Another issue is that not only part of the hieararchy disappears, it also reverts back to default values of the transform instead of what is set in RCP: This is in RCP: This is in the simulator/headset: I'm filing a feedback ticket too and will post the number here. Anyone had a similar issue and found a fix or workaround ?

If I long press on an element, the sidebar disappears and then a Done appears on the screen, but nothing else changes, so what are the Environments in Vision Pro's Simulator?

Hello all, I saw this interesting VisionOS app: https://apps.apple.com/us/app/splitscreen-multi-display/id6478007837 I was wondering if there was any documentation on the Swift APIs that were used to create this app.

At a recent community meeting we were wondering how Apple creates this soft-edge effect around the occlusion cutouts. We see this effect on keyboard cutouts, iPhone cutouts, and in progressive spaces. An example: Notice the soft edged around the occlusion cutout for the keyboard One of our members created some Shader Graph materials to explore soft edges. These work by sending data into the opacity channel of the PreviewSurface node. Unfortunately, the Occlusion Surface nodes lack any sort of input. If you know how to blend these concepts with RealityKit Occlusion, please let us know!

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

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 !!
