Xcode: 11.2.1 (11B500)

iOS: iPadOS13.3 beta3 (Japanese)

Device: iPad Pro (11-inch, 2018)

I tried two types of code.

(oneView is an AR view)

Code:

import SwiftUI
import RealityKit

struct ContentView: View {
   
    var body: some View {
        NavigationView {
            List {
            VStack {
                NavigationLink(destination: oneView()) {
                    Text("Watch")
                }
                }.navigationBarTitle("AR")
    }
    }.navigationViewStyle(StackNavigationViewStyle())
}
}

struct ARViewContainer: UIViewRepresentable {
   
    func makeUIView(context: Context) -> ARView {
       
        let arView = ARView(frame: .zero)
       
        // Load the "Box" scene from the "Experience" Reality File
        let boxAnchor = try! Experience.loadBox()
       
        // Add the box anchor to the scene
        arView.scene.anchors.append(boxAnchor)
       
        return arView
       
    }
   
    func updateUIView(_ uiView: ARView, context: Context) {}
   
}

#if DEBUG
struct ContentView_Previews : PreviewProvider {
    static var previews: some View {
        ContentView()
    }
}
#endif

Code:

import SwiftUI

struct ContentView: View {
    var body: some View {
        NavigationView {
            List {
            NavigationLink(destination: oneView()) {
                Text("Show Next")
            }
            }
        }
    }
}
