This book is about Swift 3.0 and iOS. I will explain ideas and concepts that exist in iOS and Swift. I will show how I would write code and provide justifications for my decisions. Then I want you, the reader, to decide for yourself how you want to write your code using your newfound techniques and concepts.
My goal is not to tell you how to write Swift code, but give you the knowledge you need to feel comfortable deciding how to write your own code. I want to structure the book in this way because I have seen too many books and articles that describe how to do a particular task. They give you a list and explain what task each piece accomplishes. However, they never teach you why or how it could change, depending on the circumstances. Software development is an art form and there are many ways to structure the same solution.
