title: AdMob Banner ad not showing when running app
body: <p>I think that I setup the code for the Banner Ad correctly but the is is not showing up when I run the application in the simulator or on my iPhone. </p>
  
  <pre><code>@IBOutlet var BannerAD: GADBannerView!
  
  @IBOutlet var ScoreLabel: UILabel!
  
  var taps = Int(){
      didSet {
          if taps == 330 {
              print("You have reaches 5 taps !!")
          }
      }
  }
  
  
  override func viewDidLoad() {
      super.viewDidLoad()
      //BannerView
      let request = GADRequest()
      request.testDevices = [kGADSimulatorID]
      BannerAD.delegate = self
      BannerAD.adUnitID = "ca-app-pub-1469592343938512/3073825187"
      BannerAD.rootViewController = self
      BannerAD.loadRequest(request)
  </code></pre>
