Compute differences between two sequences of elements.

These can be passed to updateSection extensions to animate transitions.

Example

// Update self.items array of view models
let previous: [ViewModel] = self.items
self.items = model.currentViewModels()
let diff = previous.diff(self.items)

// Animate changes to view models array
self.tableView.beginUpdates()
self.tableView.updateSection(0, diff: diff)
self.tableView.endUpdates()
