In this chapter, we have developed a great basis for Swift knowledge. We have learned about the various built-in mechanisms Swift has for representing complex information in expressive and accessible ways. We know that, by default, we should declare information as a constant until we find a practical need to change it, and then we should make it a variable. We have explored how every piece of information in Swift has a type associated with it by the compiler, whether it is through type inference or declared explicitly. We are familiar with many of the built-in types, including simple types like String
, Int
, and Bool
as well as containers like tuples, arrays, and dictionaries. We can use the console output to better investigate our programs, especially by using string interpolation for dynamic output. We recognize the power of controlling the flow of our programs with if
statements, conditionals, switches, and loops. We have functions in our skill set to write more legible, maintainable...

Overview of this book
Swift is Apple’s new programming language and the future of iOS and OS X app development. It is a high-performance language that feels like a modern scripting language. On the surface, Swift is easy to jump into, but it has complex underpinnings that are critical to becoming proficient at turning an idea into reality.
This book is an approachable, step-by-step introduction into programming with Swift for everyone. It begins by giving you an overview of the key features through practical examples and progresses to more advanced topics that help differentiate the proficient developers from the mediocre ones. It covers important concepts such as Variables, Optionals, Closures, Generics, and Memory Management. Mixed in with those concepts, it also helps you learn the art of programming such as maintainability, useful design patterns, and resources to further your knowledge. This all culminates in writing a basic iOS app that will get you well on your way to turning your own app ideas into reality.
