Dwifft is a small Swift library that tells you what the "diff" is between two collections, namely, the series of "edit operations" required to turn one into the other. It also comes with UIKit bindings, to automatically, animatedly keep a UITableView/UICollectionView in sync with a piece of data by making the necessary row/section insertion/deletion calls for you as the data changes.

Dwifft is a Swift library that does two things. The first thing sounds interesting but perhaps only abstractly useful, and the other thing is a very concretely useful thing based off the first thing.

The first thing (found in ) is an algorithm that calculates the diff between two collections using the Longest Common Subsequence method. If this kind of thing is interesting to you, there's a pretty great paper on diffing algorithms: http://www.xmailserver.org/diff2.pdf

The second thing (found in ) is a series of diff calculators for s and s. Let's say you have a that's backed by a simple array of values (like a list of names, e.g. . If that array changes (maybe Bob
