apple.uikit.NSDiffableDataSourceSnapshot<_SectionIdentifierType,_ItemIdentifierType>

All Implemented Interfaces:

NSCopying, NSObject

public class NSDiffableDataSourceSnapshot<_SectionIdentifierType,_ItemIdentifierType>
extends NSObject
implements NSCopying

A NSDiffableDataSourceSnapshot represents the complete state of a UI element (e.g. UICollectionView)

Snapshots can be created in two ways: 1. From a connected data source: e.g. UICollectionViewDiffableDataSource.snapshot() This will contain the current state of the UI element.

2. Constructing a new instance: e.g. NSDiffableDataSourceSnapshot() This will construct an empty snapshot with no section or item identifiers.

Notes: 1. All identifiers must be unique. Section and Item identifiers do not overlap and may contain values that exist in the other (i.e. it is OK to have a section identifier == 1 and an item identifier == 1)

2. If you pass duplicate values in an item or section array (e.g. -appendItemsWithIdentifiers:), the system will throw an exception.
