If you have a for loop method that calls a method and you want to calls this methods concurrent, so just use this :

DispatchQueue.concurrentPerform(iterations: Int, execute: { (count) in
   doSomethingFor(count: count)
}

But if you have some individuals methods that you want to call concurrent, just do like this:

let concurrentQueue = DispatchQueue(label: "com.some.concurrentQueue", attributes: .concurrent)

concurrentQueue.async {
    //executable code
    myFirstMethod()
}

concurrentQueue.async {
    //executable code
       mySecondMethod()
}

This way concurrentQueue, will manages your tasks concurrently itself.
