AFAIK there's no "libc" on macOS. libSystem is "libc".

libc (under the name libsystem_c.dylib) is one of several components that make up libSystem. But none of these dylibs (including libSystem itself) actually exist in the installed image as dylibs: they’re part of the dyld shared cache.
We’re talking about the developer experience, not the implementation. Assuming the IDE doesn’t do it for them, they’re going link against libsystem.
