# CKModifyRecordsOperation.RecordSavePolicy.changedKeys

A policy that instructs CloudKit to save only the fields of a record that contain changes.

## Declaration

```swift
case changedKeys
```

## Discussion

Discussion important: This policy doesn’t compare record change tags. To only save changes to the most recent version of a record, use CKModifyRecordsOperation.RecordSavePolicy.ifServerRecordUnchanged instead.
