# DISPATCH_QUEUE_PRIORITY_LOW

Tasks run at a low priority, which is equivalent to the utility quality-of-service level.

```
var DISPATCH_QUEUE_PRIORITY_LOW: Int32 { get }
```

## Discussion

Use quality-of-service constants instead. This constant maps to the `QOS_CLASS_UTILITY` class.

Items dispatched to the queue run at low priority; the queue is scheduled for execution after all default priority and high priority queues have been scheduled.
