# desiredKeys The fields of the records to fetch. ``` @property (nonatomic, copy, nullable) NSArray * desiredKeys; ``` ## Discussion Use this property to limit the amount of data that CloudKit returns for each record. When CloudKit returns a record, it only includes fields with names that match one of the keys in this property. The property’s default value is `nil`, which instructs CloudKit to return all of a record’s keys. If you intend to specify a value other than `nil`, do so before you execute the operation or add the operation to a queue. --- Copyright © 2026 Apple Inc.
