Re: [swift-users] QualityOfService for concurrentPerform in Swift 3

2016-09-27 Thread Daniel Müllenborn via swift-users 
I do not understand why this works, but when you create a queue in the line 
before. It will be used.

Like in this example:

let queue = DispatchQueue.global(qos: .default)
DispatchQueue.concurrentPerform(iterations: n)

You might be looking for the DispatchQoS.QoSClass 
 enum.
