Having some fun with the marshal operator in Swift

marshalMadness.swift

import UIKit

// The marshal operator is reviewed in this blog post…
// http://ijoshsmith.com/2014/07/05/custom-threading-operator-in-swift/

// Don't ever do something this ridiculous in a real app!
func printMarshalOperator()
{

                                          {p("M")}
                                          ~> {p("O")};
              {p("A")}                       ~> {p("P")};
        {p("R")} ~> {p("E")};          {p("S")} ~> {p("R")};
    {p("H")}          ~> {p("A")}; {p("A")}  ~> {p("T")};
                              {p("L")}      ~> {p("O")};
                                             {p(" ")}
                                        ~> {p("R")};
    
    
}

func p(message: String) {
    dispatch_async(dispatch_get_main_queue()) { print(message) }
}

class ViewController: UIViewController
{
    @IBAction func handleButton(sender: AnyObject)
    {
        // Prints MARSHAL OPERATOR to the console
        printMarshalOperator()
    }
}

very cool, and utterly bonkers!

Thanks! :)

Ha! Clever!
