Apple: visionOS support
!8581 (merged) added support for Apple's visionOS using a Xcode 15 beta version. However, the final Xcode 15.0 release does not include visionOS support. The download page says:
For development with the visionOS SDK, continue to use Xcode 15 beta 8.
Therefore all our "Xcode >= 15" tests cannot be used to infer visionOS support.
Furthermore, even on versions of Xcode that do offer visionOS, installation of its SDK is an option. Therefore our conditions, at least in the test suite, will need to detect its presence somehow, or be told by explicit configuration.
