# CLSProgressReportingCapability.Kind.duration

Time spent performing the task.

## Declaration

```swift
case duration
```

## Discussion

Discussion The framework automatically measures the time that a student spends working on a task, so all contexts have a CLSProgressReportingCapability.Kind.duration capability by default. You can replace the default one with a new one if you want to customize the details string.
