mergeChanges(fromRemoteContextSave:into:)

Handles changes from other processes or from a serialized state.

Declaration

class func mergeChanges(fromRemoteContextSave changeNotificationData: [AnyHashable : Any], into contexts: [NSManagedObjectContext])

Mentioned in

Accessing data when the store changes

Discussion

This method more efficiently merges changes into multiple contexts as well as nested contexts. The dictionary keys should be one or more from an NSManagedObjectContextObjectsDidChange: NSInsertedObjectsKey, NSUpdatedObjectsKey, NSDeletedObjectsKey. The values should be an NSArray of either NSManagedObjectID or NSURL objects conforming to valid results from uriRepresentation().
