Design

Welcome to Part 2 of this book. At this point, you’re familiar with the Xcode user interface, and you have a solid foundation of using Swift. In this part, you’ll start creating the user interface of a journal app, named JRNL. You will use Interface Builder to build the screens that your app will use, add elements such as buttons, labels, and fields to them, and connect them together using segues. As you will see, you can do this with a minimum of coding.

This part comprises the following chapters:

• Chapter 10, Setting Up the User Interface
• Chapter 11, Building Your User Interface
• Chapter 12, Finishing Up Your User Interface
• Chapter 13, Modifying App Screens

By the end of this part, you’ll be able to navigate the various screens of your app in the iOS Simulator, and you will know how to prototype the user interface of your own apps. Let’s get started!
