DISPATCH_QUEUE_PRIORITY_DEFAULT
Tasks run at the default priority, which is equivalent to the default quality-of-service.
Declaration
var DISPATCH_QUEUE_PRIORITY_DEFAULT: Int32 { get }Discussion
Use quality-of-service constants instead. This constant maps to the QOS_CLASS_DEFAULT class.
Items dispatched to the queue run at the default priority; the queue is scheduled for execution after all high priority queues have been scheduled, but before any low priority queues have been scheduled.
