Becoming a Great iOS Developer

Abstract

Now that you’re ready to become a software developer and have read the introduction of this book, you need to become familiar with several key concepts. Your computer program will do exactly what you tell it to do—no more and no less. It will follow the programming rules that were defined by the operating system and the Swift programming language. Your program doesn’t care if you are having a bad day or how many times you ask it to perform something. Often, what you think you’ve told your program to do and what it actually does are two different things.
