・Writing code that’s easier to understand, maintain, improve, and evolve
・Choosing the most efficient and effective way to accomplish key tasks when multiple options exist
・Making the most of key system libraries such as Grand Central Dispatch
・Writing Objective-C object-oriented code the right way
・Taking advantage of key language subtleties, such as the difference between Objective-C “protocols” and multiple inheritance in other languages
・Optimizing code by using arrays, dictionaries, and sets more effectively
・Gaining a far deeper understanding of both the language and its underlying runtime
