Unit 3: Navigation and Workflows|Navigation and Workflows

After these past two units, you should be ready to work toward more complex interfaces and interactions. You've learned the basics of Xcode, the development environment for building iOS apps, and you've had a chance to try out Interface Builder, a visual tool for creating user interfaces. After building a simple project, you went on to learn something about the Swift language, including fundamental programming concepts that enabled you to finish up the Apple Pie game.

In this unit, you'll learn about an important Swift feature for working with optional data. You'll also learn how to use multiple scenes, views, and controls to build simple workflows.

By the end of this unit, you should feel comfortable using Interface Builder and storyboards to build the user interface for apps with multiple views.
