UICollectionView doesn't scale with size classes

Question

I'm using a UICollectionView and SizeClasse. When I build and run the code on a 4-inch device, there is some black space at the bottom and at the top over the status bar. If I use the Xcode Storyboard Preview, it looks okay. I have the same problem in the simulator.

Can anyone help me please?

Thank you for your answer.

You need to provide LaunchImages for all device sizes.
