5. Go to the storyboard -> select new Cell -> Attributes Inspector -> set Identifier to "YourCell".
6. Go to YourViewController file, create reuseIdentifier constant and set it's vaule to "YourCell".
7. Go to the storyboard -> drag delegate and dataSource connections from UICollectionView to YourViewController
8. Implement UICollectionViewDataSource protocol via Swift extension
