Using the Explore screen
When the app is launched, you will see the Explore screen:
Figure 9.6 – Explore screen
Let's study the different parts of this screen.
A UITabBar instance (tab bar) at the bottom of the screen displays Explore and Map buttons. The Explore button is selected, and you see a collection view displaying a list of cuisines in collection view cells. A UICollectionReusableView instance (section header) containing a LOCATION button is at the top of the screen.
Before you can pick a cuisine, you have to select a location by tapping the LOCATION button.
