DeepDiff
Amazingly incredible extraordinary lightning fast diffing in Swift
...The library relies on models conforming to a diff-aware protocol so items can be uniquely identified and compared. This makes it useful for deciding which elements were inserted, deleted, moved, or replaced between two versions of a dataset. DeepDiff helps reduce unnecessary UI reloads by making updates more targeted and animation-friendly. The repository is archived, so it is best treated as a stable reference or legacy dependency rather than an actively evolving Swift package.
