I'm trying to build Creating a Photogrammetry Command-Line App, getting the same error on my macOS 12 beta (21A5534d) and Xcode 13.0 (12A233). What can I do now?
BTW there's a warning:
The macOS deployment target 'MACOSX_DEPLOYMENT_TARGET' is set to 12.0, but the range of supported deployment target versions is 10.9 to 11.3.99.
My default target is indeed 12.0 by default, so this warning seems weird. Is it related to the error in question?
