AutoDiff

Diffing is a very popular technique in modern mobile apps development. It's easy to convert changes between two lists (inserts, deletes, moves, updates) into a UICollectionView batch update.

To find changes between arrays, elements must be Hashable or Diffable:

let old = Array("abc")
let new = Array("abcd")

let changes = Diff.between(old, and: new)

Provided implementation is based on the Paul Heckel's algorithm.

CollectionViewAdapter uses diffing to animate UICollectionView updates.
