There's typo errors (no url variable in the call) in your code.

Anyway, in Swift 3 it's better to use the new URL struct and the URLSession class.

Also, XCPlayground is now PlaygroundSupport.

And no need to use NSString when String is available.

import PlaygroundSupport
PlaygroundPage.current.needsIndefiniteExecution = true

let url = URL(string: "http://stackoverflow.com/")
let task = URLSession.shared.dataTask(with: url!) { (data, response, error) in
    if let data = data,
        html = String(data: data, encoding: String.Encoding.utf8) {
            print(html)
    }
}
task.resume()

Note: this is for Xcode 8 beta 2. On beta 1 you would have to do shared() instead of shared. If you're on iOS don't forget to import UIKit, but this code also works for OS X if you import Cocoa instead.
