Hi, I don't have a solution to your problem, but I can tell you why it fails. According to the xcodebuild man page, when platform is set to macOS, the only other keys that can be included in your destination specifier are arch and variant. Sorry I can't help any further. H.

Bug report filed, no answer received.

I'm also experiencing this problem across multiple OSes and Xcode versions. The only (tiny) difference is that I'm not getting an exit code at all, unlike the original poster who is seeing a 65. I'd like to report a bug as suggested above, but I'm not sure what crash log from ~/Library/Logs/DiagnosticReports/ to include. What file am I looking for? We have approximately 10 asset catalogues in our project - is there any way of finding out which one is causing the crash?
