It seems that the WWDC20 Ray Tracing examples need a Intel Skylake GPU or above, the Skylake was included in MacBooks released in Early 2016. But the Ray Tracing examples do not seem to work with the Intel Xeon W in the iMac Pro and also the new Mac Pro 2019? The Mac Pro is Apple's most powerful machine, surely the Intel Xeon W should have enough power to run the Ray Tracing examples? When I try to run the sample below I get the error "Ray tracing isn't supported on this device".

Using the new SceneKit SceneView in SwiftUI how do I turn on the SceneKit debug parameters? The current options parameter only takes a limited number of Options? https://developer.apple.com/documentation/scenekit/sceneview/options struct ContentView : View {     @State var theScene = SCNScene(named: "ship.scn")!     @State private var pointOfView = "distantCamera"     public var body: some View {         ZStack {             SceneView(                 scene: theScene,                 pointOfView: theScene.rootNode.childNode(withName: pointOfView, recursively: true),                 options: [ .allowsCameraControl, SCNDebugOptions.showBoundingBoxes ] 	- [ERROR]             )             Button(action: {                 // Can I turn on debug for SceneView here?                 // show SCNView statistics such as fps and timing information                 scnView.showsStatistics = true  - [ERROR]                 scnView.debugOptions = [.renderAsWireframe, .showBoundingBoxes]  - [ERROR]             }) {                 Text("Debug").padding(.top, 300)             }         }     } }

The new RealityKit 2 ECS enhancements from #WWDC21 are awesome but to learn them I need a simple example! Could someone please post a simple RealityKit 2 ECS example that rotates a simple cube using a Rotate Component? If the Rotate Component is added then the cube should rotate. If the Rotate Component is removed then the cube should stop rotating.
