# DispatchQoS.QoSClass.default

The default quality-of-service class.

## Declaration

```swift
case `default`
```

## Discussion

Discussion Default tasks have a lower priority than user-initiated and user-interactive tasks, but a higher priority than utility and background tasks. Assign this class to tasks or queues that your app initiates or uses to perform active work on the user’s behalf.
