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 Closes https://github.com/Instagram/IGListKit/pull/494 Reviewed By: amonshiz Differential Revision: D4696966 Pulled By: rnystrom fbshipit-source-id: f21b8341b3ed4389f2a4a106d0d316f481ba6943
