title: NSDate error using scheduledTimerWithTimeInterval: Extra argument 'selector' in call
body: <p>I can't figure out for the life of me why Xcode is throwing the error "Extra argument 'selector' in call."  The method signature is fine and there is no extra 'selector' argument.  Also, the auto complete brings the method up but Option-clicking on scheduledTimerWithTimeInterval says "No Quick Help" and the font is black instead of purple as if the compiler is not recognizing it.  Here is the  code:</p>
  
  <pre><code>import UIKit
  
  class ViewController: UIViewController {
  
      @IBOutlet weak var timerLabel: UILabel!
      @IBOutlet weak var startButton: UIButton!
      @IBOutlet weak var stopButton: UIButton!
      var timer = NSTimer()
  
      override func viewDidLoad() {
          super.viewDidLoad()
  
          startButton.layer.cornerRadius = 5.0
          stopButton.layer.cornerRadius = 5.0
  
          // Do any additional setup after loading the view, typically from a nib.
      }
  
      override func didReceiveMemoryWarning() {
          super.didReceiveMemoryWarning()
          // Dispose of any resources that can be recreated.
      }
  
  
      @IBAction func didPressStartButton(sender: AnyObject) {
  
      timer = NSTimer.scheduledTimerWithTimeInterval(1.0, target: self, selector:Selector("updateTimeLabel"), userInfo: NSDate(), repeats: TRUE)
  
      }
      func updateTimerLabel() {
  
  
      }
  }
  </code></pre>
