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?

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?

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.

I have some question about visionOS: Does Apple open the eye tracking API to developers? If I want to know how to achieve it, when the eyes are stared at a specific View, a Boolean value can be changed to true, and when the eyes are removed from this View, it will become false. In ImmersiveSpace, when immersionStyle is .full or .progressive, a black background will appear by default. How can I turn this background into a panorama of my own? In ImmersiveSpace, how to make a View always follow the user?

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.

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

May I ask how to find the credibility of the Apple Developer Program account?

If I learn all in https://developer.apple.com/visionos/planning/, can I master all the knowledge in visionOS development?

The default framework of visionOS is SwiftUI, but it can also be combined with UIKit in SwiftUI, and Apple has also released video documents and other content for this purpose. But what I want to know is that SwiftUI is much simpler than UIKit, but why does Apple recommend developers to combine with UIKit in SwiftUI? I also want to know what are the advantages of SwiftUI and UIKit in visionOS? I hope you can reply to my two questions. Thank you!

I now have a developer account to join the Apple developer program. Now I want to add a new developer account to the Apple developer program (with the same identity) without my original account being affected. What should I do?
