How to create dispatch queue in Swift 3

Question

In Swift 2, I was able to create queue with the following code:

let concurrentQueue = dispatch_queue_create(\"com.swift3.imageQueue\", DISPATCH_QUEUE_CONCURR         


        

Answer 1

I did this and this is especially important if you want to refresh your UI to show new data without user noticing like in UITableView or UIPickerView.

    DispatchQueue.main.async
 {
   /*Write your thread code here*/
 }
