In visionOS, once an immersive space is opened, the background color is solid black. How do I change this? I just need to set a static color without any shading, but I can't find any documentation or examples on how to do this, and the template that comes with Xcode 15.1 beta 3 doesn't change the background color. I've searched around for information, but all I can find points back to MTKView.clearColor, which I can't use when drawing into an immersive space, since immersive spaces on visionOS use Compositor Services and not MTKView or CAMetalLayer for drawing 3D content.

I see that visionOS beta 3 removed the functions cp_drawable_get_ar_pose() and ar_pose_get_origin_from_device_transform() from CompositorServices and ARKit respectively, that were in the previous betas. Why were they removed? and what are their replacement functions, if any?

How do I create & open an immersive space window scene from a UIKit view or view controller? I need to create one in order to use Compositor Services in order to draw a 3D object using Metal, but this particular GUI is drawn & laid out using UIKit, and it isn't possible for me to rewrite it to use SwiftUI. I already tried [UIApplication.sharedApplication activateSceneSessionForRequest:[UISceneSessionActivationRequest requestWithRole:UISceneSessionRoleImmersiveSpaceApplication] errorHandler:...], but all that happened was it opened a new window for the main application scene (UIWindowSceneSessionRoleApplication), instead of opening an immersive space scene as I expected. Yes, I did create a scene manifest in my app's Info.plist, with a UIWindowSceneSessionRoleApplication scene, and a CPSceneSessionRoleImmersiveSpaceApplication scene. Surely there has to be a way to do this without resorting to SwiftUI...

Is there a way to disable certain parts of SIP while enabling parts of it? If so, then how do I do this?I'd like to enable most of SIP (such as filesystem protections), but disable debugging restrictions so that I can attach a debugger to System Preferences to debug a preference pane, something that is normally not allowed. I'm aware of csrutil, but there's no manual for the tool, and the online help doesn't say whether it can do this or not.
