Hello, Im not able to get any 3d object visible in ARView. struct ARViewContainer: UIViewRepresentable { var trackingState: ARCamera.TrackingState? = nil func makeUIView(context: Context) -> ARView { // Create the view. let view = ARView(frame: .zero) // Set the coordinator as the session delegate. view.session.delegate = context.coordinator let anchor = AnchorEntity(plane: .horizontal) let box = ModelEntity(mesh: MeshResource.generateBox(size: 0.3), materials: [SimpleMaterial(color: .red, isMetallic: true)]) box.generateCollisionShapes(recursive: true) anchor.addChild(box) view.scene.addAnchor(anchor) // Return the view. return view } final class Coordinator: NSObject, ARSessionDelegate { var parent: ARViewContainer init(_ parent: ARViewContainer) { self.parent = parent } func session(_ session: ARSession, cameraDidChangeTrackingState camera: ARCamera) { print("Camera tracking state: \(camera.trackingState)") parent.trackingState = camera.trackingState } } func makeCoordinator() -> Coordinator { Coordinator(self) } func updateUIView(_ uiView: ARView, context: Context) { } } View is loaded correctly but anything cant appear. I also tried to create 3D object in func updateUIView(_ uiView: ARView, context: Context) { let anchor = AnchorEntity(plane: .horizontal) let box = ModelEntity(mesh: MeshResource.generateBox(size: 0.3), materials: [SimpleMaterial(color: .red, isMetallic: true)]) box.generateCollisionShapes(recursive: true) anchor.addChild(box) uiView.scene.addAnchor(anchor) print("Added into the view") } Print statement is printed but there is still no object in the ARView. Is it bug or what am I missing?

UiTabBar.appearance().isHidden = true seems that has no effect anymore. Is it bug or there is another way how to do it in iOS 16? On iOS < 16 when I call at init UiTabBar.appearance().isHidden = true default style is hidden. I used this modifier when I had on TabBar more than 5 items. So I was able to hide more button at the TabBar and also in navigationBar edit. But now more button and edit button are always visible.
