Please treat me as a beginner of Unity. Now I want to learn to develop visionOS VR App through unity. I try to find a relatively complete route and start learning, but Unity's official website does not have much explanation for visionOS VR App, so I hope you can give me a comparison. The whole route, thank you!

I want to test the in-app purchase in visionOS Simulator. I logged in to the Sandbox account in Simulator and was prompted to send the verification code to the phone number I wrote in the previous step. I entered the verification code accurately, but I couldn't log in normally. It was wet many times.

I hope to send my income to my Apple Cash (Apple Cash can display the virtual card number in iOS 17.4 Beta). Is this okay? If you can, how to fill in questions such as ABA Routeing Number in Agreements, Tax, and Banking? And will Apple Cash give me interest (I only have Apple Cash)

In visionOS, I want show a 3D Content, I can use RealityView or Mode3D, But the effect they achieve is similar. What is the difference between them and which one to use for users?

In order to improve App sales, I hope to promote App. At present, I only know from the VisionOS App Submission Guide that I can get the opportunity to become an editor's choice to promote the App by sharing my APP. Is there any other way to promote VisionOS App?

We can use AnchorEmpty to fix RealityView in one place, such as a wall. Now I hope that it can not only be fixed in one place, but also fill the whole place with RealityView by stretching. For example: My RealityView is a picture, which is now anchored to the wall, and ARKit will stretch the picture according to the size of the wall. How to achieve the whole wall? Thank you!

Apple launched the Developer Strap on the developer's official website, which allows developers to connect Vision Pro and Mac with USB-C, but I can't get it in China, so I want to ask developers who already have Vision Pro or People who understand these questions: Can Vision Pro without Developer Strap be debugged wirelessly? If so, How is the experience of unlimited debugging? and how does it compare with wired connection? Thank you!

I found in App Store Connect that on the 18th (Vision Pro pre-sale day), my visionOS App was purchased by a person in the United States, but this day was only pre-sale. No one really got Vision Pro, and this app is only compatible with visionOS. May I ask why?

In RealityView, I use AnchorEntity to lock to Wall to run normally: AnchorEntity(.plane(.vertical, classification: .wall, minimumBounds: .one)) But I use a location other than wall but I can't display View. Why is that?

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.

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.") TextField("Key", text: $inputText) .padding(30) .textFieldStyle(.roundedBorder) Button(action:{ socketManager.joinRoom(roomCode: inputText) self.isSheet = false }, label: { Text("Join Room") .font(.title3) }) .padding(50) } .padding() } .sheet(isPresented: $socketManager.showRoomNotFoundAlert) { Text("The room does not exist. Please check whether the Key you entered is correct.") .font(.title) .frame(width: 500) .padding() Button(action:{ self.socketManager.showRoomNotFoundAlert = false }, label: { Text("OK") .font(.title3) }) .padding() } } } } In the above code (this is a visionOS project), when I click Share, it can't display Sheet normally, and TipView can't be displayed either. Why?

Just now, we learned the exciting news that Vision Pro is about to be released! I would like to ask if there are any services such as discounts or rentals for developers? If so, can I experience it normally in China?

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

I didn't find any errors in my program, and Xcode didn't report any errors in the program code, but when I ran it, it inexplicably reported an error: Command CompileAssetCatalog failed with a nonzero exit code What should I do?

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!
