Hi, One of the great features introduced in WWDC24 is the Translation API. But unfortunately it's currently unavailable on visionOS. My question is, does Apple have any plan to support it on visionOS as well? If so, what's the ETA for this feature? I would really like to see it on visionOS, otherwise I'll have to pay Google to use their translation API.

I tried to use the application icon from sample project https://developer.apple.com/documentation/visionos/diorama, but the 3 layers of the app icon are not separated when I hover on the icon in the Vision Pro simulator. Could you please advise how to fix the problem? I am using the latest Xcode Version 15.4 (15F31d). Thank you.

I have a simple example of a motion matching (MxM for Unity) character controller that uses Unity's input system and gamepad support. In editor the scene and inputs work as expected. When I build to headset the app stops at an initialization step where my game controller should kick in. The app doesn't crash but my character is frozen in A-Pose and doesn't respond to input. I'm wondering if this error I'm seeing in the logs is what's causing it? And if so how do I fix it? error 15:56:11.724200-0700 PolySpatialProjectTemplate NSBundle file:///System/Library/Frameworks/GameController.framework/ principal class is nil because all fallbacks have failed I'm using Xcode 16 beta 6 Unity 6000.0.17f1 VisionOS 2.0 beta 9

I'm working on a school project that allows users to open a .USDZ file (using Quick Look) on the webpage while using Apple Vision Pro to put the object in their physical envirnment, the project is deployed on Vercel. I'm testing the page with my apple vision pro, when I click open the .USDZ file, I'm seeing a triangle with an exclamation mark while it's trying to load, but it won't load. Does anybody know how to troubleshoot this issue?

Hi, My app allows users to share and view spatial photos. For viewing spatial photos, I'm using a plane in a RealityView that has a camera index switch material node, which takes the stereo images as the inputs. For sharing native spatial photos taken on the vision pro, prior to visionOS 2.0, I extract the stereo image pair and merge them into a single side-by-side image to upload to the app's backend. However, since visionOS 2.0 introduced generating spatial photos from normal photos, I've been seeing some unexpected behaviours in my app, while on the other hand, they can be viewed correctly in the system Photos app: Sometimes the extracted images have different size, the right image is smaller than the left image. See the first image in the google drive below, taken with iPhone 15 Pro. Even if the image pair have the same size, when viewed in my app, it has some artefacts, especially around the edge of objects which are closer to the camera. See the second image in the google drive below, taken with iPhone 11. Google drive link here: https://drive.google.com/drive/folders/1UTfpxvO3-ChqshwfyzY5E_KCgk8VgUaa I know that now Quicklook preview application can support viewing spatial photos now, but I would like to keep it the way I implemented in the app, for compatibility concerns. Below is a code snippet that deals with the extraction. Please point out the correct way to extract stereo image pair from a generated spatial photo. Happy to submit a code-level support request if more information is needed. // the data is from photos picker item let data = try await photo.loadTransferable(type: Data.self) let source = CGImageSourceCreateWithData(data as CFData, nil) let sbsImage = source.extractSpatialPhoto() extension CGImageSource { func extractSpatialPhoto() -> UIImage? { guard let leftCGImage = extractSpatialImage(at: 0), let rightCGImage = extractSpatialImage(at: 1) else { return nil } let leftImage = UIImage(ciImage: leftCGImage) let rightImage = UIImage(ciImage: rightCGImage) guard leftImage.size == rightImage.size else { return nil } // merge left + right let size = CGSize(width: leftImage.size.width * 2, height: leftImage.size.height) UIGraphicsBeginImageContextWithOptions(size, true, 1.0) leftImage.draw(in: CGRect(x: 0, y: 0, width: leftImage.size.width, height: leftImage.size.height)) rightImage.draw(in: CGRect(x: leftImage.size.width, y: 0, width: rightImage.size.width, height: rightImage.size.height)) let mergedImage = UIGraphicsGetImageFromCurrentImageContext() UIGraphicsEndImageContext() return mergedImage } // not sure if this actually works func extractSpatialImage(at index: Int) -> CIImage? { guard let cgImage = CGImageSourceCreateImageAtIndex(self, index, nil) else { return nil } var ciImage = CIImage(cgImage: cgImage) if let properties = CGImageSourceCopyPropertiesAtIndex(self, index, nil) as?

Hello, I'm currently working on a project that requires real-world object recognition and labeling. I understand that due to the security and privacy issues, we are unable to access the vision pro camera feed. Is there any other external way to solve this problem? Thank you!

I have been implementing the LongPressGesture to have a menu come up upon a long press. I love the functionality and it is very close to being where I want it to be. I don't know if this is a visionOS-specific thing, but I am hoping to control the corner radius of the pulled-out element behind my "button." I've wrangled hover effects in the past with overlays, but I'm not sure what to target in this case. Worst case, I'll have to change the border radius on all of my tiles to match this LongPressGesture-controlled behavior, or I could possibly change the radius onLongPressGesture to match. Is there a simpler solution? Thanks!

I'm having trouble pairing my apple vision pro to my macbook pro M3, my macbook pro is on sonoma 14.6 and i have tested pairing a visionOS1.2 and 2.0 vision pro but it still doesn't work, i have a mac mini that pairs and connects fine to the headsets and those are the steps i tried to do on vision pro and macbook pro to pair them together until now but with no success : On the same windows wifi hotspot On the same iPhone hotspot On an other wifi hotspot Tried to clear remote devices, still not recognized tried to turn off and turn on developper mode still nothing tried to reset network parameters tried to restart headset tried to restart Xcode tried to restart mac just after restart the headset showed up and i clicked pair and typed in the code but then the headset was still in "disconnected" and couldn't connect to mac tried to restart mac and headset tried to rename headset tried to switch mac tried 1 headset on at a time tried to clean build folder deleted contents of ~/Library/Developer/Xcode/DerivedData tried sudo defaults write "/Library/Preferences/com.apple.mDNSResponder.plist NoMulticastAdvertisements" -bool true tried to deactivate the firewall

In my VisionPro app, I'm facing a problem with loading USDZ models from a RealityKitBundle package, created using Reality Composer Pro. It was working fine until I added more models to the package. As I added more models with large textures in the project, the app started to show them with texturing problems. So, when I load the models from the RealityView using Entity(named:in), the mesh loads correctly, but all black, with no textures, as below: However, when I load the same USDZ directly from the main bundle, using ModelEntity(named:in), it loads fine. I know that large textures can cause memory issues, but when talking about one single model, I know that it's not enough to cause a memory overflow in the VisionPro. This USDZ model is about 40MB with something around 800MB of texture memory (from the RealityComposerPro Statistic tab). I've built experiences in VisionPro with much heavier models, and they do present the same texture issues, but only after there's more than 3 huge models enabled in the Reality scene. But that's not the case. The un-textured model appears right from the beginning, so it seems to me that's not a runtime issue in the device, but rather some issue in the packaging process from RealityComposerPro to XCode to the Device, am I correct? I'm also using a simple Mac Mini with M2 but only 8MB of RAM. Maybe that's the issue? As I still want to use RealityComposerPro to build more dev-friendly and interesting applications, I'd really appreciate some guidance here! Thanks in advance!

Hi, Following the wwdc24 video - What’s new in Quick Look for visionOS, I've managed to open a 3D model using PreviewApplication by calling let previewItem = PreviewItem(url: modelURL, displayName: "Easter", editingMode: .disabled) _ = PreviewApplication.open(items: [previewItem]) However, the "Save to Downloads" option is aways there(see attached screenshot). As the models are user generated content, and I don't want the download option to be available to all users. How to disable it?

How to make a specified entity in RealityView be captured by users: This entity has physical and collision components, and the user will not change when he does not grasp the action. However, when the user makes a grab hand gesture and is very close to the entity (there can be a small deviation), an Anchor component will be enabled to bind the entity to the hand, but when the user lets go, he will fall along the y-axis of the current position (affected by the physical component). I hope you can help me. Thank you.

How to detect whether two entities collide in RealityView and execute some instructions after the collision. It is assumed that both entities have collision components, and one of them also has an anchor component (such as a binding hand).

I am honored that I successfully participated in the "Envision the future: Build great apps for visionOS"(https://developer.apple.com/events/view/ZCH7ZUY24C/dashboard) conference. However, unfortunately, I am in China, and due to the visa problem (because it usually takes at least 2 months to apply for a visa, but it only takes about 10 days from the time I received the notice to the meeting), I can't go to the United States to participate in the site. So I hope Apple can place an iPad on site and create a FaceTime link, and then I can make a call to this iPad. I also told Apple about this suggestion, but now there are only a few days left to start. They didn't reply to me. Even Apple has sent me the ticket to the Developer Center and asked me to add it to the Apple Wallet App, which means that Apple has not There is a request to deal with me. So I hope you can give me some advice or help me for those who know about this aspect. For Apple's internal engineers, if possible, I hope you can contact the person who manages this meeting. I'm very grateful for this. Thank you.

The setup:
 My Vision Pro app loads uszd models created by a 3rd party app. These models have to be scaled to the right dimension for RealityKit. I want to use physics for realistic movement of these entities, but this does not work as expected. I thus wrote a demo test app based on Apple's immersive space app template (code below).
This app has two entities, a board and above a box that is a child of the board.
 Both have a collision component and a physics body.
 The board, and thus also its child the box, are scaled. The problem:
 If the scale factor is greater or equal 0.91, the box falls under gravity towards the board where it is stopped after some movements. This looks realistic.
 However, if the scale factor is below 0.91, even 0.9, the movement of the box is immediately stopped on the board without any physics simulation.
 Unfortunately, I am not able to upload screen recordings, but if the demo app is executed, one sees the effect immediately. The question:
 I cannot imagine that this behavior is correct. Can somebody confirm that this is a bug? If so I will write a bug report.
 My demo app uses Xcode Version 16.0 (16A242d), simulator Version 16.0 (1038) and visionOS 2.0. The code: import SwiftUI import RealityKit import RealityKitContent struct ImmersiveView: View { @Environment(AppModel.self) var appModel var body: some View { RealityView { content in let boardEntity = makeBoard() content.add(boardEntity) let boxEntity = makeBox() boardEntity.addChild(boxEntity) moveBox(boxEntity, parentEntity: boardEntity) } } func makeBoard() -> ModelEntity { let mesh = MeshResource.generateBox(width: 1.0, height: 0.05, depth: 1.0) var material = UnlitMaterial(); material.color.tint = .red let boardEntity = ModelEntity(mesh: mesh, materials: [material]) let scale: Float = 0.91 // Physics does not run if scale < 0.91 boardEntity.scale = [scale, scale, scale] boardEntity.transform.translation = [0, 0, -3] boardEntity.generateCollisionShapes(recursive: false) boardEntity.physicsBody = PhysicsBodyComponent(massProperties: .default, material: PhysicsMaterialResource.generate(friction: .infinity, restitution: 0.8), mode: .static) return boardEntity } func makeBox() -> ModelEntity { let mesh = MeshResource.generateBox(size: 0.2) var material = UnlitMaterial(); material.color.tint = .green let boxEntity = ModelEntity(mesh: mesh, materials: [material]) boxEntity.generateCollisionShapes(recursive: false) boxEntity.physicsBody = PhysicsBodyComponent(massProperties: .default, material: PhysicsMaterialResource.generate(friction: .infinity, restitution: 0.8), mode: .dynamic) return boxEntity } func moveBox(_ boxEntity:Entity, parentEntity: Entity) { // Set position and orientation of the box let translation = SIMD3<Float>(0, 0.5, 0) // Turn the box by 45 degrees around the y axis let rotationY = simd_quatf(angle: Float(45.0 * .pi/180.0), axis: SIMD3(x: 0, y: 1, z: 0)) let transform = Transform(rotation: rotationY, translation: translation) boxEntity.transform = transform } }

Hello everyone, I'm a Computer Science student. My supervisor has given me some topics for my final year project, and one of them involves using Vision Pro for facial recognition—specifically, identifying a designated face to display specific information. As a developer, my understanding of Vision Pro is quite limited. I've done some research online and found that Unity and Xcode are used as development tools. Traditionally, facial recognition is done using OpenCV. However, I've come across articles stating that Apple, due to security reasons, cannot implement facial recognition. I’d like to ask if that’s true. Also, with VisionOS 2 featuring object tracking and image tracking, could these methods potentially replace facial recognition?

My app has two Window Groups: Window1 and Window2 Moving Window2 to Window1 will overlay, and I cannot see or interact with Window1. My question is, is there any way that I can make Window1 always on top, and whenever Window2 moves in front of Window1, will it be overlayed instead of Window1?

I am trying to position the share sheet popped up by the shareLink API on VisionOS, but the share sheet is always anchored by at the label position. I checked the Photos app is achieving this already, the share sheet there appears at very center of the window while the share button locates at the corner inside the menu. How is this possible to make it?

I am having trouble with initializing the SharePlay. It works but we have to leave the game (click the close button) and rejoin it, sometimes several times, for it to establish the connection. I am also having trouble sharing images over SharePlay with GroupSessionJournal. I am not able to get it to transfer any amount of data or even get recognition on the other participants in the SharePlay that an image is being sent. We have look at all the information we can find online and are not able to establish a connection. I am not sure if I am missing a step, or if I am incorrectly sending the data through the GroupSessionJournal. Here are the steps I took take to replicate the issue I have: FaceTime another person with the app. Open the app and click the SharePlay button to SharePlay it with the other person. Establish the SharePlay and by making sure that the board states are syncronized across participants. If its not click the close button and click open app again to rejoin the SharePlay. (This is one of the bugs that I would like to fix. This is just a work around we developed to establish the SharePlay. We would like it so that when you click SharePLay and they join the session it works.) Once the SharePlay has been established, change the image by clicking change 1 image. Select a jpg image. The image that represents 1 should be not set. If you dont see the image click on any of the X in the squares and it will change to the image. The image should appear on the other participant in the SharePlay. (This does not happen and is what we have not been able to figure out how to get working.) Here are the classes for the example project I created: Content View Game Model Class Activity Manager Main Starter Class

Hi, we have in our app an immersive space and we taught the palm menu button is not available in immersive spaces, but when I look in the hand and tap the menu button appear. Is it possible to keep it hidden? Because we a have an hand tracking feature in palm and when we try to press a button to overlap the palm it triggers the menu button and then when the user presses again by mistake, it sends the application to the background. This is very important for us because we would like to release this hand-tracking feature as soon as possible. Here is a link with to a video with the problem: https://drive.google.com/file/d/1cfOcdzF19h_mbmpvkVNCJjXEBJecVeJL/view?usp=sharing

I have a created an AnchorEntity for my index finger tip and then created a model entity (A sphere) as a child of it. This model entity has a collision component and a physics body component. I tried using dynamic and kinematic modes for the physics body component. I have created a plane from a cube that has collision component and a static physics body. I have subscribed to the CollisionEvents.Began on this plane. I have also stored it in a EventSubscription state variable. @State private var collisionSubscription: EventSubscription? The I subscribed as follows collisionSubscription = content.subscribe(to: CollisionEvents.Began.self, on: self.boxTopCollision, { collisionEvent in print("something collided with the box top") }) The collision event fires when I directly put the sphere above the plane and let gravity do the collision, but when the the sphere is the child of the anchor entity, the collision events don't happen. I tried adding collision and physics body component directly to the anchor entity and that doesn't work too. I created another sphere with a physics body and a collision component and input target component and manipulate it with a drag gesture. When the manipulation is happening and collide the plane and the sphere the events don't happen when my sphere is touching the plane, but when the gesture end and the sphere is in contact with the plane, the event gets fired. I am confused as to why this is happening. All I want to do is have a collider on my finger tip and want to detect the collision with this plane. How can I make this work? Is there some unstated rule somewhere as where a physics body is manipulated manually it cannot trigger collision events? For more context. I am using SpatialTrackingSession with the tracking configuration of .hand. I am successfully able to track the finger tip.
