This is also what the "official" C++ API for Metal does (https://developer.apple.com/metal/cpp/ https://developer.apple.com/metal/cpp/), it's an automatically generated bindings wrapper which calls into ObjC runtime functions without an ObjC shim inbetween). Bit of a shame that this idea isn't extended to all system frameworks and not just C++ but also C bindings (official C bindings would make life a lot easier for all other programming languages). I also dabbled a bit with this idea by parsing clang AST-dumps of macOS system headers and generate C binding functions: https://github.com/floooh/objc-ast-experiments https://github.com/floooh/objc-ast-experiments Unfortunately this is very brittle, and then also broke on ARM CPUs, I guess the shim code needs some ABI adjustments (famously, objc_msgSend has multiple "ABI shapes": https://www.mikeash.com/pyblog/objc_msgsends-new-prototype.html https://www.mikeash.com/pyblog/objc_msgsends-new-prototype.h...).
