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) > Hmm, I didn’t realize that concurrentPerform doesn’t allow you to pass in > your own queue…this looks like an oversight to me.
