# Record Changed Error Keys

Constants that represent conflicting records in a save operation.

## Discussion

If the version of a record on the server is newer than the version you try to save, the server returns a [`CKError.Code.serverRecordChanged`](/documentation/CloudKit/CKError/Code/serverRecordChanged) error. The error’s <doc://com.apple.documentation/documentation/Foundation/NSError/userInfo> dictionary contains the different versions of the conflicting records. Use these keys to retrieve the records, and to perform any resolution logic necessary to resolve the conflict.
