Comment (by mascguy):

 Replying to [comment:3 ryandesign]:
 > We have 14.0.1 on the macOS 12 buildbot worker and I don't intend to
 upgrade because 14.0.1 is the last version that contains the macOS 12 SDK
 and we want the SDK version to match the OS version because of the
 problems that not doing that typically causes.

 for anyone using Xcode 14.0 or 14.0.1:

 Sounds good, I'll fix this afternoon, unless someone beats me to it.

 desired.

 My vote would be to leave it 14.0.1. Anyone else?
