When I first started learning Objective-C, I already had a good understanding of concurrency and multitasking with my background in other languages, such as C and Java.

At first, I went into denial; there was no way GCD could manage my application's threads better than I could. Then, I entered the anger phase; GCD was hard to use and understand. Next was the bargaining phase; maybe I can use GCD with my threading code, so I could still control how the threading worked. Then, there was the depression phase; maybe GCD does handle threading better than I could. Finally, I entered the wow phase; this GCD thing is really easy to use and works amazingly...
