Ordered Collection Diffing

https://thoughtbot.com/blog/ordered-collection-diffing

Swift 5.1からCollectionのDiffが取れるようになる。 CollectionからどのIndexがInsert/Deleteされたかが取得できるようになるので、UICollectionViewなどを差分更新するのが簡単になる。 RxCocoaにも差分更新の仕組みがあったけど、代替できるかもしれない。

余談: Androidにも似たようなDiffUtilがあって、それを使ったEpoxyっていうOSSも出ている。
