Setting up a tab bar controller scene

As you saw in the app tour, the Let's Eat app has a tab bar with two buttons at the bottom of the screen, which are used to display the Explore and Map screens. You will remove the existing view controller scene and the ViewController Swift file and add a tab bar controller scene with two buttons to your project. Follow these steps:

1. Click the Main storyboard file in the Project navigator:

2. The contents of the Main storyboard file appear in the Editor area. Click the Document Outline button to collapse the document outline if it is present. This gives you more room to work with:
