# hasIncrementalChanges A Boolean value that indicates whether changes to the fetch result can be described incrementally. ``` var hasIncrementalChanges: Bool { get } ``` ## Discussion If this value is `true`, use the [`insertedIndexes`](/documentation/Photos/PHFetchResultChangeDetails/insertedIndexes), [`removedIndexes`](/documentation/Photos/PHFetchResultChangeDetails/removedIndexes), and [`changedIndexes`](/documentation/Photos/PHFetchResultChangeDetails/changedIndexes) properties (or the [`insertedObjects`](/documentation/Photos/PHFetchResultChangeDetails/insertedObjects), [`removedObjects`](/documentation/Photos/PHFetchResultChangeDetails/removedObjects), and [`changedObjects`](/documentation/Photos/PHFetchResultChangeDetails/changedObjects) properties) to find out which objects in the fetch result have been added, removed, or updated. You can also use the [`hasMoves`](/documentation/Photos/PHFetchResultChangeDetails/hasMoves) property and [`enumerateMoves(_:)`](/documentation/Photos/PHFetchResultChangeDetails/enumerateMoves(_:)) method to find out which objects in the fetch result have been rearranged. These properties can be useful for updating a collection view or similar interface that displays the fetch result’s contents. If this value is `false`, the fetch result is too different from its original state for incremental change information to be meaningful. Use the [`fetchResultAfterChanges`](/documentation/Photos/PHFetchResultChangeDetails/fetchResultAfterChanges) property to get the fetch result’s current membership. (If displaying the fetch result’s contents, reload your user interface to match the new fetch result.) --- Copyright © 2026 Apple Inc.
