Hi team, I believe I’ve found a registration issue between ARFrame.sceneDepth and ARFrame.capturedImage when using high-resolution frame capture on a 2022 iPad Pro (6th gen). When enabling high-resolution capture: if let highResFormat = ARWorldTrackingConfiguration.recommendedVideoFormatForHighResolutionFrameCapturing { config.videoFormat = highResFormat } … arView.session.captureHighResolutionFrame { ... } the depth map provided by ARFrame.sceneDepth no longer aligns correctly with the corresponding high-resolution capturedImage. This misalignment results in consistently over-estimated distance measurements in my app (which relies on mapping depth to 2D pixel coordinates). iPad Pro (6th gen): misalignment occurs only when capturing high-resolution frames. iPhone 16 Pro: depth is correctly registered for both standard and high-resolution captures. It appears the camera intrinsics, specifically the FOV, change between the “regular” resolution stream and the high-resolution capture on the iPad. My suspicion is that the depth data continues using the intrinsics of the lower resolution stream, resulting in an unregistered depth-to-RGB mapping. Once I have the iPad in hand again, I will confirm whether camera.intrinsics or FOV differ between the low-res and high-res frames. Is this a known issue with high-resolution frame capture on the 2022 iPad Pro? If not, I’m happy to provide some more thorough sample code. Thanks for your time!

I like to compose an APN message. (using FCM) what shall I do for it?

I am developing an IOS App that allow users to scan rooms, view the scans on device, and add notes. I need to preserve actual geometry (odd angles, chamfers, fixtures), not simplified RoomPlan boxes. Are there any easy ways to incorporate high quality texture mapping or PBR? Where is the documentation for scene reconstruction?

How can I create 180-degree apple immersive videos using game engine

I'm developing a custom gesture-based visionOS project that uses hand tracking with collision detection spheres on fingers to register user interactions through collision components. I'm experiencing a critical occlusion issue where collision detection spheres are intermittently occluded by the background/depth buffer, causing fingers to pass through the 3D model entities without registering interactions. Detailed Description: I have added 3D entities in an immersive scene with collision spheres attached to fingers for detecting user interactions. Each sphere has: CollisionComponent with sphere shape Proper collision masks and groups configured Real-time position updates from hand joint transforms Each entity has: InputTarget components to register collisions The Issue: When users move their fingers to the entity to interact, some collision spheres (particularly on the pinkie and ring fingers) become occluded and pass directly through the 3D model without triggering collision events. Meanwhile, other fingers (like the index finger) continue to work correctly. This appears to be a depth perception/z-buffer issue between the model entity and the hand tracking collision spheres Questions: Is there a recommended approach for maintaining consistent depth ordering between hand-tracking entities and 3D models in immersive spaces to prevent occlusion issues? Should I be using AnchorEntities to anchor the entity to a plane or world position to establish a more stable depth reference? Are there specific RenderingComponent or material settings that could help ensure collision entities maintain their depth priority and don't get occluded? Could this be related to z-fighting when collision spheres and entity geometry occupy similar depth ranges? If so, what's the recommended depth bias approach? Is there a better architectural approach for implementing interactions with custom hand gesture tracking that avoids these depth perception issues? What Would Help: Implementation guidance for ensuring reliable collision detection between hand-tracked entities through custom gestures and 3D models. Best practices for depth management in immersive spaces with custom hand gesture tracking. Sample code demonstrating stable hand-to-object interaction patterns. Information about whether this is a known limitation or if there are specific APIs I should be leveraging This issue is significantly impacting the reliability of our app experience, as users cannot consistently interact with all model components. Any guidance from Apple engineers or developers who have solved similar depth/occlusion challenges would be greatly appreciated. Additional Context: This is for a productivity-focused application where accuracy and reliability are critical. Thank you for any assistance!

Since only the user can take a screenshot using the Apple Vision Pro's top buttons, the only workaround available to an immersive app that needs a screenshot to document the user's creative interior design choices is ask the user to take a screenshot wait until the user taps a button indicating the screenshot has been taken then the app asks the user to select the screenshot when the app opens the PhotoPicker when the user presses Done, the screenshot is handed off to the app. One wonders why there is no Apple Api for doing this in a simple privacy protective way such as: When called, the Apple api captures the screenshot in Apple secured memory The api displays the screenshot to the user with appropriate privacy warnings and asks if the user wants to a. share this screenshot with the app, or b. cancel, c. retake the screenshot If the user approves, the app receives the screenshot

Hello! Back from last week's amazing visit to Cupertino for the Game Dev session and diving back into Vision Pro experimentation. I've exported a simple geometry nodes with animation test from Blender for use in RCP, with intended output to Vision Pro. I've attached a few screenshots showing the node setup and how it animates over time. I select the Cube mesh and export as .usdc with animation. In the finder via quick look, I can actually see it working! If I try exporting as .usdz, however, i'm not seeing any animation in the finder preview. Next, I import the .usdc file to RCP and add an Animation Library component to the cube mesh, but am not seeing any animation selectable, even though I see animation playing back in preview. Next, I import the .usdc into Maya (via proper USD Stage pipeline - i'm learning to be USD compliant for authoring!) to verify if the animation is working, and it does. What step(s) am I missing to get this working in Reality Composer Pro? My goal is to experiment with animating these geometry node instances - along with color animation if possible - over to Vision Pro for full scale, immersive presentation. Of particular note, I am not a programmer, so I am trying my best to brute force this the only way I currently know possible, by keyframe animation and importing through Reality Composer Pro. I realize that, ideally, I should be learning how to leverage the code portion so I can start programatically controlling my 3d entities (with animation), but need more hand holding and real-world examples to help me get there. Thx!

I work on motion capture systems for VTubing. I can't seem to find any information on gaining access to the Face Tracking features on iOS while developing for Vision OS. I would love to bring VStreamer Live to Vision OS

Hi, I'm trying to place an object in front of AVPlayer that is docked in VideoDockingRegion, but when launched in immersive space, the video passes through the objects placed in front of. How do I make sure these objects are visible? image for reference

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...

Environment visionOS 26.1, Xcode 26.1.1 Problem When a WindowGroup opens an ImmersiveSpace and the user closes the window via X button, the async Task in .onDisappear gets cancelled before dismissImmersiveSpace() completes, leaving the ImmersiveSpace active with no way to exit. Steps WindowGroup opens ImmersiveSpace in .onAppear User clicks X to close window .onDisappear fires but async cleanup cancelled ImmersiveSpace remains active, user trapped Expected ImmersiveSpace dismissed when window closes Actual ImmersiveSpace remains active Code .onAppear { Task { await openImmersiveSpace(id: "VideoCallMainCamera") } } .onDisappear { Task { await dismissImmersiveSpace() // Gets cancelled } } What I've Tried Task in .onDisappear ❌ scenePhase monitoring ❌ High priority Task ❌ .restorationBehavior(.disabled) + .defaultLaunchBehavior(.suppressed) ✅ (prevents restoration but doesn't fix immediate cleanup) Question What's the recommended pattern for ensuring ImmersiveSpace cleanup when WindowGroup closes? Is there a way to block window closure until async cleanup completes, or should ImmersiveSpaces automatically dismiss with their parent window?

Hello everyone, I'm a new developer and I'm still learning the foundations of Swift and SwiftUI while building my first app. Today I wanted to ask you how to implement AR Quixck Views inside my app. I wanna be able to dynamically preview AR objects in a dedicated view, however, I don't seem to have understood where and how to locate AR objects inside my project. I tried including them in the Assets folder of the project, or in the Recources folder, or within the main folder of my project alongside the MyAppApp.swift file. None of the methods I used seemed have worked in that none of the objects was ever located. I made sure to specify the path to the files every time, but somehow the location isn't recognized. I also tried giving no path so that the app would search for the files in their default location (which I apparently haven't grasped yet), but still my attempt failed. I don't have the code sample on me at the moment, but I will write a followup comment on this post to show you what I wrote in case anyone was interested in debugging my code. Meanwhile, if anyone would be so kind to point me at the support article or to comment below the sample code they used in their app, I would very much appreciate it, so that I can start debugging. Thank you for reading this, I appreciate you.

Hello Community, I’m currently working with the sample code “CapturingDepthUsingTheLiDARCamera” and using it to capture the depth map of an image taken with the iPhone 14 Pro. From this depth map, I generate a point cloud using the intrinsic camera parameters. I've noticed that objects not facing the camera directly appear distorted in the resulting point cloud. For example: An object with surfaces that are perpendicular to each other appears with a sharper angle in the point cloud — around 60° instead of 90°. My question is: Is this due to the general accuracy limitations of the LiDAR sensor? Or could it be related to the sample code? To obtain the depth map, I’m using: AVCapturePhoto.depthData.converting(toDepthDataType: kCVPixelFormatType_DepthFloat32) Thanks in advance for your help!

Can you help to write a code able to pick an element a bit far from me, then bring it near to me, flick it a bit and then send it back to its original position when I release it? Thanks a lot, Christophe

Hi. I am mixing content destined for Vision Pro. Locked to video. I have the AAX installer and the ASAF video player demonstrated in the quicktimes is nit included in the install package for pro tools. Would it be possible to post a link ?

Are there any changes to RotationSystem: System and RotationComponent: Component that I should be aware of to see if I need to update my use in my visionOS app?

I'm currently implementing 180° / 360° immersive video for my app. I easily implemented 360° by just applying VideoMaterial to flipped sphere. But I'm stuck at 180°. I'm trying to implement by applying VideoMaterial to hemisphere (half sphere). I want to make VideoMaterial to be visible half front sphere and half back sphere transparent / clear. Would there be any advice / information / idea to implement this? Your help would be grateful.

I am still not finding resources to know how to replace hands in a full immersive Space.... I reached the goal by creating a ARKit session that can detect the USDZ hand mesh Joints and connect to the hand-tracked-joints.... but I feel that's not the best solution... I really want to use the RealityKit potential to track and replace hands (with USDZ skinned ones) in an immersive environment, but the only resources I found are from November 2023.... :( Can someone help me?

Hi, Few days ago, Apple had another "Meet with Apple" event regarding immersive video : Create immersive media experiences for visionOS | Meet with Apple days one and 2 and it is not appearing on my Developer app in Mac. The same happened to IETF HLS Interest Day | Meet with Apple. Any tip? Kind regards , Bruno
