The number of mentions indicates the total number of mentions that we've tracked plus the number of user suggested alternatives.
Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

C-Macs – a pure C macOS application
Here's something similar by Garret Bass:

...I also experimented a bit with parsing macOS system headers via clang-ast-dump and then code-generating C and Zig APIs but that didn't get far:
https://github.com/floooh/objc-ast-experiments
...with a bit of effort and maybe using libclang instead of clang-ast-dump that's definitely feasible though.
I guess a similar approach is used by the official C++ bindings for Metal:

Space-shooter.c: cross-platform, top-down 2D space shooter written in C
Metal can be called from C by going directly through the Objective-C runtime, but it requires either macro magic (like: https://github.com/garettbass/oc/), or code-generated C headers.
But it's not a big deal to move all the ObjC code into a separate .m source file and expose a smaller and higher level C API.

C-Macs – a pure C macOS application
If you want to optimize this (and you enjoy pain), you can eliminate the dependency on objc/* headers and use compiler attributes and link sections to compile your code to the same(ish) assembly that Objective-C compiles to. I don't have a C example on hand, but here's a Rust example that's pretty easy to translate to C: https://github.com/objrs/objrs/blob/master/HOW_IT_WORKS.md
