# NSFileManagerResumeSyncBehavior

The behaviors the file manager can apply to resolve conflicts when resuming a sync.

## Declaration

```swift
enum NSFileManagerResumeSyncBehavior
```

## Overview

Overview You use this type when calling resumeSyncForUbiquitousItem(at:with:completionHandler:) to resume synchronizing. In most situations, the NSFileManagerResumeSyncBehavior.preserveLocalChanges behavior is the best choice to avoid risk of data loss.
