In visionOS, in ImmersiveSpace, how to let users drag a specific view?

In visionOS, have many code with 3D attributes (SwiftUI) is adapted from the code in iOS, like: .padding(_:) to .padding3D(_:). In iOS have .offset(x:_, y:_), it only have X and Y, but in visionOS, view is in a 3D scene, so I want offset have Z, but offset can't use Z, so I try offset3D: import SwiftUI //Some View .offset3D(x: Number, y: Number, z: Number) Xcode report an error: Error: No member 'offset3D' So do you now how to use like offset's Modifiers, and can use Z in visionOS.

I successfully changed a picture to the background in ImmersiveSpace in a full state with the following code. import RealityKit struct MainBackground: View { var body: some View { RealityView { content in guard let resource = try? await TextureResource(named: "Image_Name") else { fatalError("Error.") } var material = UnlitMaterial() material.color = .init(texture: .init(resource)) let entity = Entity() entity.components.set(ModelComponent( mesh: .generateSphere(radius: 1000), materials: [material] )) entity.scale *= .init(x: -1, y: 1, z: 1) content.add(entity) } } } However, when running, I found that when the user moves, the background is not fixed, but follows the user's movement, which I feel unrealistic. How to fix the background in the place where it first appears, and give the user a kind of movement that is really like walking in the real world, instead of letting the background follow the user.

Just now, I accidentally deleted Xcode15.1 Beta3. Now I want to download it again, but I found that Xcode 15.1 Release Candidate replaced Xcode15.1 Beta3 in https://developer.apple.com/download/applications/, but there is no visionOS SDK in Xcode 15.1 Release Candidate, so I really need to download Xcode15.1 Beta3 now. Who has any way for me to download it again?

In reality composer pro, when importing an USDZ model and inserting it into the scene, reality composer pro will remove the material of the model itself by default, but I don't want to do this. So how can reality composer pro not remove the material of the model itself?

Some functions cannot be tested in the normal state of the visionOS virtual machine, such as hand tracking, and I need to test these functions. Excuse me, in addition to applying for Dev Kit and participating in the laboratory, how can I test these special functions?

How to add a light source to the View of the visionOS APP.

In the visionOS app project, you can lock to wall / floor / ceiling / table / seat / window / door through Plane classifications. How can I lock a View to one of them and change a Bool variable to true after successful locking?

I developed a Plane-detection using ARKit in the visionOS app: import SwiftUI import RealityKit import ARKit struct ContentView: View { @State private var ok = false let session = ARKitSession() let planeData = PlaneDetectionProvider(alignments: [.horizontal, .vertical]) var body: some View { Group { if !ok { TabelView() } else { SwiftUIView() } } .onAppear{ Task { try await session.run([planeData]) for await update in planeData.anchorUpdates { if update.anchor.classification == .table { continue } switch update.event { case .added, .updated: ok = true case .removed: ok = false } } } } } } When I ran it, I found that Xcode told me that it does not support Simulator, so how can I test this program? If there is no other way other than applying for VisionPro DevKit and participating in Lab, I hope you can tell me that this View is Can the following functions be realized: When there is no table in the user's sight, SwiftUIView() will be displayed in the coordinates of x:0,y:0,z:0. If there is a table in the user's sight, TabbelView() will be displayed on the table. If you can't realize the above functions, I hope you can give me some advice. Thank you!

I implemented multiple languages through Localizable.strings in the visionOS App. Now I want to test whether multiple languages can work properly, so I want to change the system language in the settings before testing, but I can't find the relevant page in the settings. What should I do?

When the visionOS App is developed, when will it be submitted to the reviewer?

I hope to be able to display the USDA model in RealityComposerPro and play the Spatial Audio. I used RealityView to implement these contents: RealityView{ content in do { let entity = try await Entity(named: "isWateringBasin", in: RealityKitContent.realityKitContentBundle) content.add(entity) guard let entity = entity.findEntity(named: "SpatialAudio"), let resource = try? await AudioFileResource(named: "/Root/isWateringBasinAudio_m4a", from: "isWateringBasin.usda", in: RealityKitContent.realityKitContentBundle) else { return } let audioPlaybackController = entity.prepareAudio(resource) audioPlaybackController.play() } catch { print("Entity encountered an error while loading the model.") return } } but when I ran it, I found that although can displayed the model normally, Spatial Audio failed to play normally. I hope to get guidance, thank you!

I found that my visionOS Simulator is very strange. Many functions and features are missing. For example, I learned from the Internet that the immersive scenes of Environments in their visionOS Simulator can be opened, but I click There was no response after the attack. There are not only these, but also many system features. I saw on the Internet that other developers have them, and I am missing. I'm worried that this will have an impact on me when testing my app. May I ask why? Some information: My updated Xcode version is the latest Xcode15.1Beta. Device: iMac (2021) Simulator system number: 21N305

import SwiftUI import TipKit struct ChatRoomView: View { @StateObject private var socketManager = SocketIOManager() @State private var inputText: String = "" @StateObject var viewModel = SignInWithAppleViewModel() @Binding var isCall: Bool @State private var isSheet = false @State private var ShowView = false var learnlisttip = KeyTip() @Binding var showShareSheet: Bool @Binding var codeshar: String var body: some View { NavigationStack{ VStack { if let roomCode = socketManager.roomCode { ZStack{ VStack{ HStack{ Text("Room Key: \(roomCode)") .font(.title) .onAppear{ codeshar = roomCode self.isCall = true } Button(action:{ self.showShareSheet = true }, label:{ Image(systemName: "square.and.arrow.up.fill") .accessibilityLabel("Share") }) } .padding(20) TipView(learnlisttip, arrowEdge: .top) .glassBackgroundEffect() .offset(z: 20) Spacer() } List(socketManager.messages, id: \.self) { message in Text(message) } TextField("input", text: $inputText) Button("send") { socketManager.sendMessage(roomCode: roomCode, message: inputText) inputText = "" } } .sheet(isPresented: $showShareSheet) { let shareContent = "Open SpatialCall, Join this Room, Key is: \(codeshar)" ActivityView(activityItems: [shareContent]) } } else { HStack{ Button(action:{ withAnimation{ socketManager.createRoom() } }, label: { VStack{ Image(systemName: "phone.circle.fill") .symbolRenderingMode(.multicolor) .symbolEffect(.appear, isActive: !ShowView) .font(.largeTitle) Text("Add Room") .font(.title3) } }) .buttonStyle(.borderless) .buttonBorderShape(.roundedRectangle) .padding(.horizontal, 30) .glassBackgroundEffect() .offset(z: 20) .scaleEffect(1.5) .padding(60) Button(action:{ withAnimation{ self.isSheet = true } }, label: { VStack{ Image(systemName: "phone.badge.checkmark") .symbolRenderingMode(.multicolor) .symbolEffect(.appear, isActive:!ShowView) .font(.largeTitle) Text("Join Room") .font(.title3) } }) .buttonStyle(.borderless) .buttonBorderShape(.roundedRectangle) .padding(.horizontal, 30) .glassBackgroundEffect() .offset(z: 20) .scaleEffect(1.5) .padding(70) } } } .onAppear { DispatchQueue.main.asyncAfter(deadline: .now() + 1.0) { withAnimation { self.ShowView = true } } } .sheet(isPresented: $isSheet){ VStack{ Text("Join Room") .font(.largeTitle) Text("You need to get the key to the room.")

Why?

In visionOS project, How does the model in RealityView track a certain part of the body, such as left foot, right leg, left arm, etc., and store the position information of the model moving in the following part in a variable (in order to realize the transmission of body part information in the call). Please let me know if Apple publishes a document about the Persona virtual camera.
