Diffable Datasource Overview
AppStore JSON APIs
Another new API introduced in iOS 13 is the UICollectionViewDiffableDatasource. This new api allows us to much more easily control the cells that are rendered inside of our UICollectionView. Prior to the Diffable Datasource, managing all of the items inside arrays and indexPath insertion/deletion was a real big headache. In the next couple of sections, I'll illustrate how to setup this entire process.
