Adding a collection view to the Explore screen
A collection view is an instance of the UICollectionView class. Like a spreadsheet program, it displays a grid of cells. Each cell in a collection view is a collection view cell, which is an instance of the UICollectionViewCell class. You'll start by adding a collection view to the view controller scene for the Explore screen in the Main storyboard file, then you'll add Auto Layout constraints to make it fill the screen.
