# NSFileManagerResumeSyncBehavior.preserveLocalChanges

Resumes synchronizing by uploading the local version of the file.

## Declaration

```swift
case preserveLocalChanges
```

## Discussion

Discussion If the server has a newer version, the server may create a conflict copy of the file, or may automatically pick the winner of the conflict. Apps can choose to implement conflict handling themselves by passing NSFileManagerResumeSyncBehaviorAfterUploadWithFailOnConflict.
