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 pe 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
