DifferenceKit

Benchmarks show DifferenceKit is the fastest Swift diffing library, processing 100,000 elements in 0.0348 seconds, outperforming competitors like RxDataSources and IGListKit.

Supports all diff types including cross-section moves and reloads, enabling complex UI animations that libraries like Differ or Dwifft lack, as highlighted in the feature comparison.

Stages diffs to prevent crashes during batch updates in UITableView and UICollectionView, addressing a common pitfall that other frameworks don't automatically solve.

Handles both linear and sectioned collections with duplicate elements, offering versatility over frameworks like IGListKit that lack sectioned support.
