Compositional CollectionView and Combine

Compositional CollectionView and Diffable DataSource

There are three sections, Featured, Shared and General pictures. They are rendered by using three seperate layouts one for each.

All the sections scroll horizontally and this is done by setting section.orthogonalScrollingBehavior = .groupPaging

Snapshots are created when data changes which are applied to collectionView to render the changes.
