Qt already runs on Vision Pro as "Designed for iPad", using Qt for iOS. This change enables building Qt for visionOS directly, which opens the door to visionOS specific APIs and use-cases such as volumes and immersive spaces. The platform removes some APIs we depend on, notably UIScreen, so some code paths have been disabled or mocked to get something up and running. As our current window management approach on UIKit platforms depends on UIWindow and UIScreen there is currently no way to bring up QWindows. This will improve once we refactor our window management to use window scenes. To configure for visionOS, pass -platform macx-visionos-clang, and optionally add -sdk xrsimulator to build for the simulator.
