visionOS RealityView attachment SwiftUI controls don't always respond to user interaction
My visionOS app has a RealityView with an attachment containing SwiftUI controls, and occasionally the controls in the attachment don't respond to user interaction. Is this a known issue? Is there a workaround? Are RealityView attachments only intended to be output only? Using visionOS 1.0 beta 3 (Xcode 15 beta 8), I've reproduced this problem with a small standalone Xcode project. I submitted the issue as FB13143132 with lovingly hand-crafted artisan repro steps. The Xcode project is also available at https://github.com/drewolbrich/AttachmentControls Thank you for investigating this issue. Screenshot my use case:

RealityView attachments do not show up in Vision Pro simulator
I have added an attachments closure in an RealityView as outlined in WWDC session "Enhance your spatial computing app with RealityKit" but it's not showing up - neither in Xcode preview window nor in Vision Pro simulator. I have used example code 1:1, however, I had to load the entity async with "try? await" to satisfy the compiler. Any help is appreciated, thx in advance!

Y and Z axis of RealityView coordinate space appear to be flipped in visionOS Simulator
Is this a know bug or is there a funamental misunderstanding on my part? In the screenshot I've attached below I would expect the blue box to be perpendicular to the floor. It is the yAxisEntity in my code which I instatniate with a mesh of height 3. Instead it runs parallel to the floor what I'd expect to the z axis. Here is my code struct ImmerisveContentDebugView: View { @Environment(ViewModel.self) private var model @State var wallAnchor: AnchorEntity = { return AnchorEntity(.plane(.vertical, classification: .wall, minimumBounds: SIMD2<Float>(0.1, 0.1))) }() @State var originEntity: Entity = { let originMesh = MeshResource.generateSphere(radius: 0.2) return ModelEntity(mesh: originMesh, materials: [SimpleMaterial(color: .orange, isMetallic: false)]) }() @State var xAxisEntity: Entity = { let line = MeshResource.generateBox(width: 3, height: 0.1, depth: 0.1) return ModelEntity(mesh: line, materials: [SimpleMaterial(color: .red, isMetallic: false)]) }() @State var yAxisEntity: Entity = { let line = MeshResource.generateBox(width: 0.1, height: 3, depth: 0.1) return ModelEntity(mesh: line, materials: [SimpleMaterial(color: .blue, isMetallic: false)]) }() @State var zAxisEntity: Entity = { let line = MeshResource.generateBox(width: 0.1, height: 0.1, depth: 3) return ModelEntity(mesh: line, materials: [SimpleMaterial(color: .green, isMetallic: false)]) }() var body: some View { RealityView { content in content.add(wallAnchor) wallAnchor.addChild(originEntity) wallAnchor.addChild(xAxisEntity) wallAnchor.addChild(yAxisEntity) wallAnchor.addChild(zAxisEntity) } } } And here is what the simualtor renders
