Instance Property

previousServerChangeToken

The change token from a previous fetch operation.

Declaration

@NSCopying var previousServerChangeToken: CKServerChangeToken? { get set }

Discussion

Assign the token you received previously from the fetchDatabaseChangesCompletionBlock to this property. Doing so yields only the changes that have occurred since your last fetch operation. If you specify nil for this parameter, the operation starts fetching changes at the beginning.
