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

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.

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 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?

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 learned Sharplay from the WWDC video. I understand the creation of seats, but I can't learn some of the following contents well, so I hope you can help me. The content is as follows: I have set up the seats. struct TeamSelectionTemplate: SpatialTemplate { let elements: [any SpatialTemplateElement] = [ .seat(position: .app.offsetBy(x: 0, z: 4)), .seat(position: .app.offsetBy(x: 1, z: 4)), .seat(position: .app.offsetBy(x: -1, z: 4)), .seat(position: .app.offsetBy(x: 2, z: 4)), .seat(position: .app.offsetBy(x: -2, z: 4)), ] } It was mentioned in one of my previous posts: "I hope you can give me a SharePlay Button. After pressing it, it will assign all users in Facetime to a seat with elements quantified in TeamSe lectionTemplate.", and someone replied to me and asked me to try systemCoordinator.configuration.spatialTemplatePreference = .custom (TeamSelectionTemplate()), however, Xcode error Cannot find 'systemCoordinator' in scope How to solve it? Thank you!

Since my question exceeds 700 words, please check it in the attachment. Thank you! Question

In vision OS, the tab bar of TabView is outside the window by default. If I switch a page without TabView to a page that needs TabView in my program, the tab bar will suddenly appear on the left side of the screen without any animation. I hope it has an animation when it appears (such as easeIn, move). I tried it in Tab. Other animation-related modifiers such as animation are added under View, but there is no animation in the tab bar. Only the view in the tab has an animation effect, but this is not what I want. What I want is that the tab bar outside the window can have animation. What should I do?

This is a visionOS App. I added contextMenu under a combination view, but when I pressed the view for a long time, there was no response. I tried to use this contextMenu in other views, which can be used normally, so I think there is something wrong with this combination view, but I don't know what the problem is. I hope you can remind me. Thank you! Views with problems： struct NAMEView: View { @StateObject private var placeStore = PlaceStore() var body: some View { ZStack { Group { HStack(spacing: 2) { Image(systemName: "mappin.circle.fill") .font(.system(size: 50)) .symbolRenderingMode(.multicolor) .accessibilityLabel("your location") .accessibilityAddTraits([.isHeader]) .padding(.leading, 5.5) VStack { Text("\(placeStore.locationName)") .font(.title3) .accessibilityLabel(placeStore.locationName) Text("You are here in App") .font(.system(size: 13)) .foregroundColor(.secondary) .accessibilityLabel("You are here in App") } .hoverEffect { effect, isActive, _ in effect.opacity(isActive ? 1 : 0) } .padding() } } .onAppear { placeStore.updateLocationName() } .glassBackgroundEffect() .hoverEffect { effect, isActive, proxy in effect.clipShape(.capsule.size( width: isActive ? proxy.size.width : proxy.size.height, height: proxy.size.height, anchor: .leading )) .scaleEffect(isActive ? 1.05 : 1.0) } } } }

In the apple map of some areas, there will be a very realistic real-life 3D map. And now I want to call it through 3d in visionOS (like model3d). How can I call it? Note: What I ask for is not to have an effect similar to 3d on a flat screen like in iOS, but to display the USDZ model in visionOS.

In Xcode16Beta4, it contains Predictive Code Completion, and Predictive Code Completion is also with other SDKs in the page opened by Xcode for the first time. Waiting for download. However, I want to know: 1. What is Predictive Code Completion? 2. I didn't download Predictive Code Completion on the SDK download page when I first opened Xcode. Where should I download it later?
