Do the following,

in your apps main view controller "viewDidLoad" method add an observer,

NSNotificationCenter.defaultCenter().addObserver(self,
        selector: "SomeNotificationAct:",
        name: "SomeNotification",
        object: nil)

And also add a method

func SomeNotificationAct(notification: NSNotification){     
    dispatch_async(dispatch_get_main_queue()) {
     self.performSegueWithIdentifier("NotificationView", sender: self)
    }
}

and add the below code in your "didReceiveRemoteNotification" method of Appdelegate class of your app

 func application(application: UIApplication, didReceiveRemoteNotification userInfo: [NSObject : AnyObject]){

     NSNotificationCenter.defaultCenter().postNotificationName("SomeNotification", object:nil, userInfo:someData)
}
