The secret to success is persistence. Never give up,

never doubt yourself. The path to any goal will never be easy, but that’s exactly what makes striving for goals so rewarding. Talent, intelligence, and skill are never as important
as persistence. Remember, never be afraid of failure. Be afraid of giving up too soon and never realizing your true potential in whatever dream you want to achieve. You may not always reach your dreams, but pursuing big dreams will always give you a far richer life than if you never bothered trying at all. 


CHAPTER 1

Organizing Code

Programs are rewritten and modified far more often than they are ever created. That means most of the time developers will be changing and altering existing code either written by someone else or written by you sometime in the past. Since you may be writing code that you or someone else will eventually modify in the future, you need to make sure you organize your code to make it easy to understand.

While every developer has their own programming style and no two programmers will write the exact same code, programming involves writing code that works and writing code that’s easy to understand.

Writing code that works is hard. Unfortunately once developers get their code to work, they rarely clean it up and optimize it. The end result is a confusing mix of code that works but isn’t easy to understand. To modify that code, someone has to decipher how it works and then rewrite that code to make it cleaner to read while still working as well as the original code. Since this takes time and doesn’t add any new features, it’s often ignored.

Since few developers want to take time to clean up their code after they get it to work, it’s best to get in the habit of writing clear, understandable code right from the start. That involves several tasks:

  • Writing code in a consistent and understandable style

  • Making the logic of your code clear so anyone reading it later can easily understand how it works

  • Organizing code to make it easy to modify later

    Writing code in a consistent and understandable style means predictability. For example, some programmers give all IBOutlet variables a prefix of “IB” to stand for IBOutlet such as
