Becoming a Great iOS or Mac Programmer

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 programming language.
