In the previous comment you said I should use objc_msgSend, now you say I shouldn't. Make up your mind. ;-)

Anyway, I'm using AppKit and UIKit to write apps. The API is Objective-C. That's why I write Objective-C.

Whatever the heck you're talking about—you appear to be confused, so I don't know what exactly you mean technically—it certainly sounds like premature optimization, which is a waste of time and not the correct utilitarian choice. My Objective-C code is not "slow". Could it be infinitesimally "faster" in way that's not even perceivable by the user? Perhaps, but who cares?
