Where can I find a comprehensive list of Swift compiler flags with documentation?

Where can I find a comprehensive list of Swift compiler flags with documentation?

I am trying to figure out what options I can set on a per-file basis in Xcode using the "Compiler Flags" field in the Compile Sources build phase:

Ever since Xcode 13, I keep getting build errors that such-and-such file was modified during the build, which is expected since these files are generated by a build script in a prior build phase.

So I would like to disable that particular error on these files. How can I do so?

Or is this just a known bug in Xcode 13?

Thanks.

Check out XcodeBuildSettings.com for a complete reference of every build setting supported for the latest version of Xcode.

But which one of those settings can be used in this field? How do I know if that's a comprehensive list?

Surely there is some official documentation somewhere about this?

Perhaps the omniscient @xwu might know?

I don't know if they are comprehensive, but maybe swiftc --help-hidden and swiftc -frontend --help-hidden could help?
