Tapping the Map button in the tab bar displays the Map screen:

Let's study the different parts of this screen.

A Tab Bar at the bottom of the screen displays Explore and Map buttons. The Map button is selected, and you see a Map Kit View displaying a map on the screen, with pins indicating restaurant locations. 

Tapping a pin will display an annotation, and tapping the button in the annotation will display the Restaurant Detail screen for that restaurant.

This completes the tour of the app. You did not cover everything on this tour, but you will in later chapters. For now, it's time to start building the UI for your app!
