The number of completed units of work for the current job.

```
var completedUnitCount: Int64 { get set }
```

## Discussion

For an [`Progress`](/documentation/Foundation/Progress) with a kind of [`file`](/documentation/Foundation/ProgressKind/file), the unit of this property is bytes, and the [`fileTotalCountKey`](/documentation/Foundation/ProgressUserInfoKey/fileTotalCountKey) and [`fileCompletedCountKey`](/documentation/Foundation/ProgressUserInfoKey/fileCompletedCountKey) keys in the `userInfo` dictionary report the overall count of files.

For any other kind of [`Progress`](/documentation/Foundation/Progress), the unit of measurement doesn’t matter as long as it’s consistent. You can report the values to the user in the [`localizedDescription`](/documentation/Foundation/Progress/localizedDescription) and [`localizedAdditionalDescription`](/documentation/Foundation/Progress/localizedAdditionalDescription).

[`fractionCompleted`](/documentation/Foundation/Progress/fractionCompleted)
