Actually, I think it should work on AppKit as well: The current ABI on MacOS and iOS supports passing more parameters to a function than it actually takes. As long as the caller passes in the "sender" target, the called function can not declare it and be fine, it will just be ignored. (This isn't guaranteed by ANSI, so is not strictly correct code, but it does work on the Mac, iPhone and iPad and is documented to do so).
