In a listing program in WWDC24, it shows that users can control the robot to walk by pinching and sliding. However, I haven't found any documents or videos related to this function. If you know, please let me know. Thank you!

When I run my visionOS App, RealityKitContent Report an error： Tool terminated by signal 'Segmentation fault: 11' And it points to a USDZ model I imported, but in the scene, my model can be displayed normally and there is no damage. Why does an error occur? How can I check and repair it?

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?

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.

When I wanted to call the Reality Composer Pro scene containing Object Tracking, I tried the following code: RealityView { content in if let model = try? await Entity(named: "Scene", in: realityKitContentBundle) { content.add(model) } } Obviously, this is wrong. We need to add some configurations that can enable Object Tracking to Reality View. What do we need to add?

In the AudioServicesPlaySystemSound function of AudioToolbox, you can enter the corresponding SystemSoundID to play some sound effects that come with the system. However, I can't be sure what sound effect each number corresponds to, so I want to know all the sound effects in visionOS and its corresponding SystemSoundID.

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?

My App needs to send and receive messages to the server, but my server does not have SSL, so I can only disable ATS in the development stage. But if I want to put the app on the shelf, then I still disable ATS when I put it on the shelf, and the server still does not have SSL. Will it be packaged? Is pp warned and terminated by Xcode? Will it be rejected by the Apple audit department? Can it be put on the App Store normally and provided to all users? Note: My server is completely safe without any security risks. I didn't apply for SSL just because I didn't have enough funds.

We can add many models in the Reality Composer Pro scene, but when I use RealityView to display and add modifiers in SwiftUI, the modifiers will have Effect, and I don't want to do this. I hope this modifier will be valid for a single model in the Reality Composer Pro scenario. May I ask how to add modifiers to a single model in the Reality Composer Pro scene?

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!

I followed the WWDC video to learn Sharplay. I understood the first creation of seats, but I couldn't learn some of the following content very well, so I hope you can give me a list code. The contents are as follows: I have already taken a seat. 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)), ] } 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 TeamSelectionTemplate. Thank you very much.

How to display the user's own persona in a view

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.
