When I download and install Xcode-beta 16 I get the following error with the app not opening. Xcode v15.4 opens fine on an Apple M2 Max running Sonoma 14.5. "Loading a plug-in failed. The plug-in or one of its prerequisite plug-ins may be missing or damaged and may need to be reinstalled.". Anyone know how to resolve? I am trying to experience Timelines in Reality Composer Pro and need 16 beta+ to try it.

Based on info online I'm under the impression we can add spatial audio to USDZ files using Reality Composer Pro, however I've been unable to hear this audio outside of the preview audio in the scene inspector. Attached is a screenshot with how I've laid out the scene. I see the 3D object fine on mobile and Vision Pro, but can't get audio to loop. I have ensured the audio file is in the scene linked as the resource for the spatial audio node. Am I off on setting this up, it's broken or this simply isn't a feature to save back to USDZ? In the following link they note their USDZ could "play an audio track while viewing the model", but the model isn't there anymore. Can someone confirm where I might be off please?

For the Vision Pro I want to create a mixed reality experience in Immersive Mode, however when I enter immersive mode in the Simulator, the background goes black when I want to continue seeing the living room (or whatever room someone is in). I notice in the ImmersiveView code it lists adding a skybox. Does that mean ImmersiveView is VR or full visual takeover of the room, like with a skybox and not mixed reality, or I need to make changes? Thanks. import SwiftUI import RealityKit import RealityKitContent struct ImmersiveView: View { var body: some View { RealityView { content in // Add the initial RealityKit content if let immersiveContentEntity = try? await Entity(named: "Immersive", in: realityKitContentBundle) { content.add(immersiveContentEntity) // Add an ImageBasedLight for the immersive content guard let resource = try? await EnvironmentResource(named: "ImageBasedLight") else { return } let iblComponent = ImageBasedLightComponent(source: .single(resource), intensityExponent: 0.25) immersiveContentEntity.components.set(iblComponent) immersiveContentEntity.components.set(ImageBasedLightReceiverComponent(imageBasedLight: immersiveContentEntity)) // Put skybox here. See example in World project available at // https://developer.apple.com/ } } } } #Preview { ImmersiveView() .previewLayout(.sizeThatFits) }

I'm trying to run this demo, which opened a month ago, but now returns 2 issues in xCode: https://developer.apple.com/documentation/visionos/diorama My goal is to better understand how to use Reality Composer Pro to develop visionOS apps for the Vision Pro. BillboardSystem.swift:39:58 Value of type 'WorldTrackingProvider' has no member 'queryDeviceAnchor' Cannot find 'Attachment' in scope. Preview paused shows. Any thoughts on where I'm off? Thanks!
