This is the full source code for a demo app accompanying the Swift NSFetchedResultsController Trickery blogpost on iOS Nomad. It is used to demonstrate the following techniques:
- Using a meta data entity for fetching
- Arbitrary section ordering
- Animating between different grouping of data
- Semantic drag 'n' drop
- Showing empty sections through a proxy
