Getting Serious on the Playground

I know, let’s write a streaming web radio application!

Don’t panic; this isn’t as scary as you think. We can get this running with shockingly little code. But let’s do so in a new playground. Close the current playground window, and use File > New > Playground to create a new playground. Call it WebRadioPlayground. Keep the line that says import UIKit, but delete the var str = "Hello, playground" line, and replace it with the following:

playing/WebRadioPlayground.playground/Contents.swift

import AVFoundation 
let url = URL(string: 
    "http://www.npr.org/streams/aac/live1_aac.pls") 
let player = AVPlayer(url: url!) 
player.play() 

Nothing will happen just yet, but hang in there… ...
