removedIndexes
The indexes from which objects have been removed from the fetch result.
Declaration
var removedIndexes: IndexSet? { get }Discussion
Use this index set to remove elements from a collection view or similar user interface that displays the contents of the fetch result. These indexes are relative to the original fetch result (the fetchResultBeforeChanges property); when updating your app’s interface, apply removals before insertions, changes, and moves.
If the hasIncrementalChanges property’s value is false, this property’s value is nil.
