PSA: it looks like last night the Xcode Cloud default build environment switched to "macOS Sonoma 14.3 RC (23D56)”, for some reason this won't build any visionOS targets for me. I get a "visionOS is not installed" error during archive.
Manually overriding this back to “macOS Sonoma 14.2 (23C64)" got things building correctly again. I suspect this will get resolved, but in the meantime that seems a solid workaround.
