# userInfo

A dictionary of arbitrary values for the receiver.

```
var userInfo: [ProgressUserInfoKey : Any] { get }
```

## Discussion

A KVO-compliant dictionary that changes in response to [`setUserInfoObject(_:forKey:)`](/documentation/Foundation/Progress/setUserInfoObject(_:forKey:)). The dictionary sends all of its KVO notifications on the thread that updates the property.

Some entries have meanings that the `NSProgress` class recognizes. For more information, see Recognizing Kinds of Progress, Using General Keys, Using File Operation Keys, and  Recognizing Kinds of File Operations.
