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

DispatchQueue.main.async(execute: {

// write code

})

Serial Queue :

let serial = DispatchQueue(label: "Queuename")

serial.sync { 

 //Code Here

}

Concurrent queue :

 let concurrent = DispatchQueue(label: "Queuename", attributes: .concurrent)

concurrent.sync {

 //Code Here
}
