Objective-C: Using the __attribute__ Directives

@NolanOBrien of the Twitter Engineering team on __attribute__ directives in Objective-C:

In this post, we’ll examine what __attribute__ directives are and how they can be used in development. The goal is to establish a value to using __attribute__ directives in any codebase and to provide a starting point with some directives that anyone can start using right away.

No question, this is the most complete tutorial I’ve found on usage of the __attribute__ directives. Highly recommended.
