I would like to make a button using SwiftUI. When the button is pressed, the model will hide. I have already read the tutorial in this link (

CodePudding user response：

You are loading your model twice – at first in makeUIView() method and secondly in hide() method. Try my version.

import SwiftUI
import RealityKit

struct ContentView : View {

    @State private var arView = ARView(frame: .zero)
    @State private var scene = try! Experience.loadBox()

    var body: some View {
        ZStack{
            ARViewContainer(arView: $arView, scene: $scene)
                .ignoresSafeArea()
            VStack {
                Spacer()
                Button("Hide Model") { hideModel() }
            }
        }
    }
    private func hideModel() {
        if arView.scene.anchors.count > 0 {
            if arView.scene.anchors[0].isAnchored {
                scene.notifications.notify.post()
            }
        }
    }
}

struct ARViewContainer : UIViewRepresentable {

    @Binding var arView: ARView
    @Binding var scene: Experience.Box
    
    func makeUIView(context: Context) -> ARView {
        arView.scene.anchors.append(scene)
        return arView
    }
    func updateUIView(_ view: ARView, context: Context) { }
}
