Exactly. Using beta version Xcode is not really a good fix...

This issue was fixed on Intel Mac with Mac Monterey. However it's got its way back to Rosetta on M1 MBP. Can't use Xcode without Rosetta as some of the libs still need it. Pls fix it! @jeremyhu

I have tried both with and without Rosetta. None of them works.

My build didn't show up in testFlight...

Yes. This project has been running on Xcode 13 for quite some time with no problem. I've tested with another machine running Xcode 13 it successfully went through to TestFlight. On Xcode 14 it also failed to build onto Watch simulator with error message: [SPApplicationDelegate _terminateWK1App:]:804: WatchKit 1 apps aren't supported on this version of watchOS. Quitting "(null)" (sorry was using another browser with a different account)
