Play animation when image anchor detected - swift

Question

In RealityKit I have an image anchor. When the image anchor is detected I would like to display an object and play animation it has. I created an animation in Reality Composer. It's a simple "Ease Out" animation which comes built-in Reality Composer.
Currently, my code looks like that:
struct ARViewContainer: UIViewRepresentable {
func makeUIView(context: Context) -> ARView {
let arView = CustomARView(frame: .zero)
// generate image anchor
let anchor = AnchorEntity(.image(group: "AR Resources", name: "imageAnchor"))
// load 3D model from Experience.rcproject file
let box = try! Experience.loadBox()
// add 3D model to anchor
anchor.addChild(box)
// add anchor to scene
arView.scene.addAnchor(anchor)
return arView
}
func updateUIView(_ uiView: ARView, context: Context) {}
}

The solution is easy. Choose Reality Composer's image anchor (supply it with a corresponding .jpg or .png image). Then assign a Custom Behavior for your model. As a trigger use a Scene Start. Then apply any desired Action.
Your code will be frighteningly simple:
struct ARViewContainer: UIViewRepresentable {
func makeUIView(context: Context) -> ARView {
let arView = ARView(frame: .zero)
let scene = try! Experience.loadCylinder()
arView.scene.addAnchor(scene)
return arView
}
func updateUIView(_ uiView: ARView, context: Context) { }
}
Action will be played automatically (immediately after the image anchor appears).
