In this chapter, we took a look at the app that we are going to build throughout the course of this book. We took a look at how the screens of the app will look when we are finished with it. We created the project that we will use later on and learned about Xcode behaviors.

In the next chapter, we will develop the data model of the app using TDD. We will use structs for the model wherever we can, because models are best represented in Swift by value types. We will add some conformance to the Equatable protocol to make the comparison of the model instances easier.
