Currently I am using mixed style immersive view to place both my WindowView(plain style) and ImmersiveView content together. The issue is that the rendering depth testing may always let the virtual content block my normal WindowView. Is it possible to manually set windowedVIew always displays in the front of my virtual view in mixed style immersion? (I know modelSortGroup but it doesn't quite fits here) Or if I can dynamically change the .progressive value when the immersive space is open (set the value to zero means .mixed itself right?)

I'm using Unity 2022.3.56f, with Apple VisionOS App Mode set to 'Virtual Reality - Fully Immersive Space'. It seems that the render resolution of my game in the Apple Vision Pro when I build is well below the native resolution of the AVP displays. I can't see a setting in XR Plug-in Management Apple visionOS options, or in Quality settings, to increase the render resolutions. Is this possible? I tried setting: UnityEngine.XR.XRSettings.eyeTextureResolutionScale= 2.0f For example, but this doesn't seem to do anything to the render resolution in the build.

Platform: iOS18 Tech: RealityView Hi! I was wondering if RealityView now provides ways for their session to persist Anchor data in a world such that the anchor locations in one session can be saved and loaded in a another session that persists the exact same anchor positions. I know that ARWorldMap in ARKit does that, but I was not able to find a way to use it with RealityView. I think it's because RealityView has ARKit under its hood but does not expose the ARKit session info publicly to the client code. So I was wondering if there's a SwiftUI + RealityView approach that can help me to achieve a similar goal: Come back to the same location and see the object in exactly the same place. Thanks!

I have been experimenting some experiences in which I would like to use SharePlay to allow the app to be used by multiple users. Currently I achieved sharing a volume containing a Reality Composer Pro scene inside of it, the scene contains some entities with an animation. So far I have been able to correctly share the volume and its content, with the animation playing without problems, but once I activate SharePlay different users see different moments of the animation if no animation at all. Is there a way to synchronize animations between all the users, no matter when someone entered the SharePlay session, aside from communicating the animation time once someone joins?

My friend cannot build my visionOS project in the simulator. He gets the following error. Error: [xrsimulator] Exception thrown during compile: cannotGetRkassetsContents(path: "/Users/path/to/Packages/RealityKitContent/Sources/RealityKitContent/RealityKitContent.rkassets") In Xcode, he is able to open the RealityKitContent package in realityComposer Pro by clicking on the Package.realitycomposerpro file. No warnings show up wrt this error in RCP either. All scenes appear to be usable/navigable in RCP. This error only comes up when he tries to build the project in Xcode command+b. The is no other information in the Report Navigator's Build logs for this error. The error is always followed by this next error. Error: Tool exited with code 1 Yikes, please help!

I am submitting a challenge to the Swift Student Challenge. I have created a RealityContent folder using Reality Composer Pro. How can I import this folder into the Swift Package Manager (.swiftpm) project hosted on Playground to ensure that it becomes a usable package?

Hi! I'm making content using Room Tracking for vision pro these days. So I searched information about it. Here the links I visited. But I could not found the info I wanted to know Apple ARKit Create enhanced spatial computing experiences with ARKit RoomTrackingProvider I wanna know that if it's possible remembering room structure that recognized before and adding contents in certain world anchor in the room space when user entered the room again? For example, a developer can save the room structure, room info (with room ID) and world anchor of the room with Room Tracking feature. After this, the developer can add entities via Xcode and Reality Composer Pro in certain position of the room to show contents to users when users enter the room. So users can see the contents whenever they visit the room. Is this possible? If there are example codes or projects about it, please let me know.

my coworkers and i are guessing at what data defines an anchor. i tried searching but struggled to find anything helpful. our best guess was a combination Triangular Irregular Networks (TIN), gps, magnetic compass direction and maybe elevation sensors. is this documented anywhere? if not, can a definition or description be provided?

In visionOS, I want to make a watch. After the actual production, the display of the hand makes it impossible to see the watch due to the virtual watch. How to set up the watch to give priority to display?

My visionOS app uses an immersive view. If the app encounters an error, I want to present an alert. I tried in a demo app to present such an alert, but it is not shown. Nearly the same code on iOS presents an alert window. Here is my demo code, based on Apple's Immersive Environment App template: import SwiftUI import RealityKit import RealityKitContent struct ErrorInfo: LocalizedError, Equatable { var errorDescription: String? var failureReason: String? } struct ImmersiveView: View { @State private var presentAlert = false let error = ErrorInfo( errorDescription: "My error", failureReason: "No reason" ) var body: some View { RealityView { content, attachments in 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]) boardEntity.transform.translation = [0, 0, -3] content.add(boardEntity) } update: { content, attachments in // … } attachments: { // … } .onAppear { presentAlert = true } .alert( isPresented: $presentAlert, error: error, actions: { error in }, message: { error in Text(error.failureReason!) }) } } Since I cannot see any alert, is something wrong with my code? How should an alert be presented in immersive space?

Hi! I wanna know if it's possible mirroring a Vision Pro to other Vision Pros. If it's possible, how do I work on it? Can I get some hints?

Hi, I have a question. In visionOS, when a user looks at a button and performs a pinch gesture with their index finger and thumb, the button responds. By default, this works with both the left and right hands. However, I want to disable the pinch gesture when performed with the left hand while keeping it functional with the right hand. I understand that the system settings allow users to configure input for both hands, the left hand only, or the right hand only. However, I would like to control this behavior within the app itself. Is this possible? Best regards.

Hi guys I'm currently developing a game for the Vision Pro and i'm trying to figure out how the hand tracking works so I can make a superpower appear when the user looks at their hand and widens it. But im really struggling to wrap my head around the whole concept and how to implement it in my code. Is there anything out there (other than apple doc) or anyone who could help me shed some light on the whole idea and how I could actually usefully implement it? would be much appreciated Thanks

How do I obtain the device's camera permissions when developing camera apps?

When I try to open Immersive space I got error like below:- HALC_ProxyIOContext::IOWorkLoop: skipping cycle due to overload How to solve it any idea?

Hey there, Just tried the visionOS 2.2 ultra-wide remote desktop feature and it's just a-m-a-z-i-n-g!! I was curious if there's an API that we can use to setup our windows in a similar fashion? (curved + ultra wide). Thank you!

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? [String: Any], let heifDictionary = properties[kCGImagePropertyHEIFDictionary as String] as? [String: Any], let extrinsics = heifDictionary[kIIOMetadata_CameraExtrinsicsKey as String] as? [String: Any], let position = extrinsics[kIIOCameraExtrinsics_Position as String] as? [Double] { // Default baseline is 64mm (0 for left camera, 0.064m for right camera) let standardBaseline = 0.064 // Check if it's the right image (should be at [0.064, 0, 0]) let isRightImage = (index == 1) let expectedPosition = isRightImage ? standardBaseline : 0.0 // Calculate the translation needed to align to standard baseline let positionDelta = position[0] - expectedPosition // Apply translation only if there's a mismatch in position if positionDelta != 0 { let transform = CGAffineTransform(translationX: CGFloat(positionDelta), y: 0) ciImage = ciImage.transformed(by: transform) } } return ciImage } }

Hi! I wanna know that if it's possible that loading Immersive Scene after scanning(recognizing) preregistered images or objects? I tried to load the Immersive scene after scanning image and objects, it didn't work well. Please let me know about the solution if it's possible. Here the ImmersiveView.swift code i tried. // ImmersiveView.swift import SwiftUI import RealityKit import RealityKitContent // Using the RealityKitContent module struct ImmersiveView: View { @ObservedObject var viewModel: TrackingViewModel @State private var immersiveScene: Entity? @State private var isToggleOn: Bool = false // Variable for toggle state var body: some View { ZStack { // Overlay RealityView and UI elements RealityView { content in if let scene = immersiveScene { content.add(scene) print("Immersive scene successfully added.") if let moneyGunsEntity = scene.findEntity(named: "MoneyGuns") { NotificationCenter.default.post( name: Notification.Name("RealityKit.NotificationTrigger"), object: nil, userInfo: [ "RealityKit.NotificationTrigger.Scene": scene, "RealityKit.NotificationTrigger.Identifier": "PlayTimeline" ] ) print("PlayTimeline notification sent.") } else { print("MoneyGuns entity not found.") } } } .onAppear { Task { if let scene = try? await Entity(named: "Immersive", in: realityKitContentBundle) { immersiveScene = scene } else { print("Failed to load immersive scene.") } } } VStack { Spacer() Toggle(isOn: $isToggleOn) { // Add toggle button Text("Toggle Option") .foregroundColor(.white) } .padding() .background(Color.black.opacity(0.7)) .cornerRadius(8) .padding() } } } }

By applying for the enterprise API, we can obtain the data of video frames collected by VisionPro glasses, and then we process the collected video frames to achieve the function of eliminating a certain object. But it was not found how to insert the processed video frames into the data source collected by the system camera. So I would like to ask if there is any API that can insert processed video frames into the original data and present them to the user? This effect is similar to the right side twist of VisionPro glasses, which allows the physical world and digital space to blend perfectly after rotation. So, I would like to ask if there is a related API that can solve this problem? STEPS TO REPRODUCE Obtain video frames, Process the obtained video frames Insert the processed video frames into the VisonOS system camera. System: VisionOS 2.0 API used: Enterprise APIs Main camera access permissions

I want a sentence custom hover effect, not a button. I want a hover effect when you look at one sentence out of many sentences. So I searched for reference videos https://youtu.be/DftRTx1oX6E , https://developer.apple.com/videos/play/wwdc2023/10110/ on apple youtube and visionOS documentation. But I haven't gotten anywhere near my wish feature yet. I respectfully request someone to help me. :)
