Try this Code:

    func application(application: UIApplication, openURL url: NSURL, sourceApplication: String, annotation: AnyObject?) -> Bool {
    var rootViewController = self.window!.rootViewController as UINavigationController
    let mainStoryboard: UIStoryboard = UIStoryboard(name: "Main", bundle: nil)
    var FirstViewController = mainStoryboard.instantiateViewControllerWithIdentifier("StoryBoardID") as FirstViewController
    rootViewController.pushToViewController(FirstViewController, animated: true)

    return true

  }
