Part 1. Your very first app
Part 1 introduces you to the basic concepts of programming and aims to quickly get your feet wet in the programming world. You’ll create your first app in chapter 2 and then in chapter 3 learn more about what you did and why you did it. Chapter 4 walks you through the tool (Xcode) that you use to create apps. You’ll go deeper into the programming world in chapters 5–7 by adding buttons and text boxes. Finally, in chapter 8, you’ll learn about an exciting tool called the Swift Playground, which allows you to learn and test code quickly and easily.
