I had a meeting with @felix-schwarz about the grid view and we decided to refactor the current UITableView class. As a result we want to move code into a new Datasource class to get a better MVC structure. This is needed, because iOS 12 and iOS 13 do not support the new UICollectionView changes, which are available since iOS 14. This means we have to implement two code paths and this is easier with moving code into a datasource class.

This needs more development time and can break, so it makes sense to move it to milestone 11.8. //cc @michaelstingl

Okay. Should be easy to remove the legacy codepath when we decide to drop it. Maybe @jesmrec can add some UI tests around it?? (basic operations, we can discuss…)
