Summary:
Started work on the plane to get this moving since #418 is up and ready to land. We'll likely need to spend some time fleshing out the API of this, and I think I'll split it up into a couple different PRs once ready for review. Putting this up now to get early feedback.
This adds an auto-diffing section controller as outlined in #38. There are several key parts:
- Subclass a new section controller `IGListAutoSectionController` (naming wip)
- Connect a data source
- Implement the data source methods that do 3 things:
- Given a top-level object, transform it into an array of **diffable** view models
- Given a view model, return a cell
- Given a view model, return a size for a cell
- A new protocol for the cell `IGListBindable` so that we can control when the cell is updated w/ the view model.
- The most important part of this is that it unlocks moving and reloading a cell, which you can't do w/ `UICollectionView`
- [ ] Unit test `reloadObjects:`
- [x] Add
