The linux job started failing after ubuntu-latest was updated

"The openStep format is unsupported on this platform"

Ah, I was wondering about this. Did this not work, hence the close?

@yonaskolb yea took a bit of a blind guess there before actually trying to build on linux. My assumption at the moment is that with the ubuntu-latest runner update from Swift 5.10.1 to Swift 6.0.1 we got the new swift foundation framework by default and it's likely failing to validate the plist xml files correctly here and marking them as openStep which doesn't seem to be supported in Linux.
