Hi, With this code on iPad Pro (11-inch) (4th generation), when capturing in area mode and pressing the "Next" Button, an overlay with a white dot in the center appears. Everything else is blurred out and the app is stuck. It does seem to work well on iPhones though. Thanks!

Since moving up to IOS18 lat week I am getting an indication that there was a significant drop in IMU data being sent. Using the search capability, I can find very little information in the Developer Documentation that will tell me what the cause is and how to remedy it. Is there some documentation repository like Tech Notes that will tell me what I need to know to get going again? What additional sources of documentation are available for developers? The Search engine used for Developer documentation just does not cut it because it delivered a lot of useless entries that have no obvious relevance to my search terms.

Hello, I am trying to develop an app that broadcasts what the user sees via Apple Vision Pro. I have applied for and obtained the Enterprise API and actually can stream via the "Main camera access" API, as reported on https://developer.apple.com/videos/play/wwdc2024/10139/. My problem is that I have not found any reference to how to integrate the "Passthrough in screen capture" API into my project. Have any of you been able to do this? Thank you

I noticed that tracking moving images is super slow on visionOS. Although the anchor update closure is called multiple times per second, the anchor's transform seems to be updated only once in a while. Another issue might be that the SwiftUI isn't updating more often. On iOS, image tracking is pretty smooth. Is there a way to speed this up somehow on visionOS, too?

Hello, I have rendered an usdz File using sceneKit's .write() method on the displayed scene. Once I load it on another RealityKit's ARView using the .nonAR mode of the camera, I am trying to use the view's raycast(from:,allowing:,alignment:) method, to get the coordinates on the model. I have applied the collisionComponents when loading the model using the .generateCollisionShapes() function to be able to interact with the modelEntity. However, the raycast result returns nothing. Is there something I am missing for it to work? Thanks!

Anybody try hand tracking provider in 2.0? I'm getting them in 11ms interval, as advertised, but they are duplicate. Here's a print of the timestamps. Problematic for me because I am tracking the last 5 position for a calculation and expect them to be unique. Can't find docs on this anywhere. I understand it's not truly 90 updates a second but predicted pose, however I expected the updates to include predicted poses.

Hello, We are wondering how and if we can save/render the view that a PerspectiveCamera sees in VisionOS. Ideally, the goal is to use a PerspectiveCamera in a Mixed Immersive space and render out what it sees. We don't see any methods exposed for rendering the view. We would truly appreciate any advice on this! Thank you.

As the question suggests, I would like to use environmental awareness and item placement functions in Unity. Does have any related example projects?

When I wanted to call the Reality Composer Pro scene containing Object Tracking, I tried the following code: RealityView { content in if let model = try? await Entity(named: "Scene", in: realityKitContentBundle) { content.add(model) } } Obviously, this is wrong. We need to add some configurations that can enable Object Tracking to Reality View. What do we need to add? Note:I have seen https://developer.apple.com/videos/play/wwdc2024/10101/, but I don't know much about it.

For visionOS 2.0+, it has been announced the object tracking feature. Is there any support for PolySpatial in Unity or is it only available in Swift and Xcode?

Hello, I am currently developing an application using RealityKit and I've encountered a couple of challenges that I need assistance with: Capturing Perspective Camera View: I am trying to render or capture the view from a PerspectiveCamera in RealityKit/RealityView. My goal is to save this view of a 3D model as an image or video using a virtual camera. However, I'm unsure how to access or redirect the rendered output from a PerspectiveCamera within RealityKit. Is there an existing API or a recommended approach to achieve this? Integrating SceneKit with RealityKit: I've also experimented with using SCNNode and SCNCamera to capture the camera's view, but I'm wondering if SceneKit is directly compatible within a RealityKit scene, specifically within a RealityView. I would like to leverage the advanced features of RealityKit for managing 3D models. Is saving the virtual view of a camera supported, and if so, what are the best practices? Any guidance, sample code, or references to documentation would be greatly appreciated. Thank you in advance for your help!

We are developing apps for visionOS and need the following capabilities for a consumer app: access to the main camera, to let users shoot photos and videos reading QR codes, to trigger the download of additional content So I was really happy when I noticed that visionOS 2.0 has these features. However, I was shocked when I also realized that these capabilities are restricted to enterprise customers only: https://developer.apple.com/videos/play/wwdc2024/10139/ I think that Apple is shooting itself into the foot with these restrictions. I can understand that privacy is important, but these limitations restrict potential use cases for this platform drastically, even in consumer space. IMHO Apple should decide if they want to target consumers in the first place, or if they want to go the Hololens / MagicLeap route and mainly satisfy enterprise customers and their respective devs. With the current setup, Apple is risking to push devs away to other platforms where they have more freedom to create great apps.

I'd like to create meshes in RealityKit ( AR mode on iPad ) in screen-space, i.e. for UI. I noticed a lot of useful new functionality in RealityKit for the next OS versions, including the OrthographicCameraComponent here: https://developer.apple.com/documentation/realitykit/orthographiccameracomponent?changes=_3 I think this would help, but I need AR worldtracking as well as a regular perspective camera to work with the 3D elements. Firstly, can I have a camera attached selectively to a few entities, just for those entities? This could be the orthographic camera. Secondly, can I make it so those entities are always rendered in-front, in screenspace? (They'd need to follow the camera.) If I can't have multiple cameras, what can be done in that case? Is it actually better to use a completely different view / API for layering on-top of RealityKit? I would much rather keep everything in RealityKit, however, for simplicity.

It's a common system interaction to look at an item in SwiftUI and tap to select it. I'm confused how to do the same with ModelEntities. How do I use gaze to select a ModelEntity for context based actions? e.g. look at the green sphere and tap to pull up a menu. Or look in a direction and clap to **** away virtual objects etc. etc. If this is not possible is there a workaround?

Question: Hi everyone, I'm developing a Vision Pro app using the latest visionOS 2, and I've encountered some issues with the new hand gestures introduced in this update. My app is designed to display a UI element when a user's palm is detected. However, the new hand gestures for navigating key functions like Home View, Control Center, and adjusting the volume are interfering with my app's functionality. What I'm Trying to Achieve Detect when a user's palm is open and display a UI element. Ensure that my app's custom hand gestures are not disturbed by the new default gestures in visionOS 2. Problem The new hand gestures in visionOS 2 (such as those for Home View, Control Center, and volume adjustment) are activating while my app is open, causing disruptions to my app's functionality. I want to disable these system-level gestures when my app is running.

With WWDC 24, I was excited to see that apple is bringing their APIs from Vision OS to iOS. I tried using the Object Anchoring component in Reality Composer Pro. Which this works with a Vision Pro, it looks like the entity will spawn at origin if we run the same on iOS and the object anchoring doesn't seem to work. Is this intended? Below is how I'm doing this. I added an Anchoring component and added the .referenceObject file I trained using CreateML. This is the code I'm using to load this scene in. // GrootView.swift // ARTest-New // // Created by Sravan Karuturi on 6/10/24. // import SwiftUI import RealityKit import Box struct GrootView: View { @StateObject private var grootVM = GrootViewModel() @State private var ent: Entity? = nil @State var anchor: Entity? = nil @State var wallAnchor: Entity? = nil @State var floorAnchor: Entity? = nil var body: some View { RealityView{ content in #if os(iOS) await content.setupWorldTracking() content.camera = .worldTracking #endif ent = try? await Entity(named: "Box", in: boxBundle) print(ent?.children) anchor = ent?.findEntity(named: "ObjectAnchor") wallAnchor = ent?.findEntity(named: "WallAnchor") floorAnchor = ent?.findEntity(named: "FloorAnchor") let updateSum = content.subscribe(to: SceneEvents.Update.self){ event in if let anc = anchor, anc.isAnchored { print("Found Item") } if let anc = floorAnchor, anc.isAnchored { print("Found Floor") } if let anc = wallAnchor, anc.isAnchored { print("Wall Anchor") } } content.add(ent!) } } } #Preview { GrootView() } While, something similar seems to work on visionOS, the same doesn't seem to work with iOS. When I run this app, we see all the children and the Found Item is printed constantly even when we don't have the item in the scene. Not really sure if this is just not supported yet on iOS ( I really hope that's not the case ) or if I messed up something somehow

When I try to train an object tracking model in Create ML, the progress bar stays stuck at 0% for about a minute. However, the training cancels soon afterwards without an additional error message. I've tried multiple different USDZ files and tried on two different Apple silicon Mac devices. Is anyone else experiencing this issue? Thank you!

Background: The app that I am working on lets the user place things in their surroundings and recovers those placements the next time their enter the immersive scene. From the documentation and discussions I have had, World Tracked Anchors are local to the device. My questions are: What happens to these anchors when the user updates their device to the next generation? What happens to these anchors if the user gets an Apple Care replacement? Are they backed up and restored via iCloud? If not, I filed a feedback about it a few months back :D FB13613066
