By: Andrew J Wagner

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.

Chapter 1. Introducing Swift

What are you trying to achieve by reading this book? Learning Swift can be fun, but most of us are trying to achieve something bigger. There is something we want to create, a career we want to follow, or maybe something else entirely. Whatever that goal is, I encourage you to keep it in mind as you read this book. It will be much easier for you to learn, from this or any other resource, if you can always relate it to your goal.

With that in mind, before we dive into learning Swift, we have to understand what it really is and how it will help us in achieving our goals. We also need to move forward with an effective learning technique and get a taste of what is to come. To do all of that, we will cover the following topics in this chapter:

  • Defining our goals for this book

  • Setting up the development environment

  • Running our first Swift code

  • Understanding playgrounds

  • Learning with this book
