Instance Property


The block to execute after the status of all changes is known.


var modifyRecordZonesCompletionBlock: (([CKRecordZone]?, [CKRecordZone.ID]?, Error?) -> Void)? { get set }


The block returns no value and takes the following parameters:


An array of CKRecordZone objects you tried to save.


An array of CKRecordZone.ID objects corresponding to the record zones you tried to delete.


An error object containing information about a problem, or nil if the results are saved successfully.

This block is executed only once and represents your only chance to process the operation results. If you intend to use this block to process results, set it before executing the operation or submitting the operation object to a queue.

This block reports an error of type CKError.Code.partialFailure when it saves or deletes only some of the record zones successfully. The userInfo dictionary of the error contains a CKPartialErrorsByItemIDKey key whose value is an NSDictionary object. The keys of that dictionary are the IDs of the record zones that were not saved or deleted, and the corresponding values are error objects containing information about what happened.
