I am trying to use the ObjectiveC runtime function class_getName which, according to the developer documentation,

 "The functions are implemented in the shared library found at /usr/lib/libobjc.A.dylib. This shared library provides support for the dynamic properties of the Objective-C language, and as such is linked to by all Objective-C applications."

Yet I get the warning that my use of class_getName is an "implicit definition" of it.

#include <objc/runtime.h>

(The above header may have been implicitly included in the past by other headers.)



I have used this and other runtime functions in other projects without receiving such a warning.

Can anyone explain what I need to do to avoid this warning? (I have a thing about my projects building with no warnings or errors).
