Clang importer error

(And several other similar errors when attempting to use debugger; Xcode 15)

Equivalent error. CMarkGFM already installed for other packages, leading to duplicate files. Build failed.

…

I get this error all the time. Is there any solution to this problem? Makes interacting with the debugger nearly impossible. Can't do a simple po command.

I get this kind of output when I try to print out a variable:

Might be best to ask somewhere like the official Swift Forums to know what to do about this kind of issue

[brendand]

@aehlke So I'm guessing you never managed to resolve this then. Mine is a mixed Objective-C and Swift application. So maybe not just a pure Swift language issue.

I have persistent but inconsistent debugger issues with a very mixed lang xcode proj
