Try this:

SecondViewController().showAlert(self)

In your second view controller

 if let text = textField?.text {
     dispatch_async(dispatch_get_main_queue(),{

      let alert = UIAlertView(title: "Working!", message: "This function was called from FirstViewController!\nTextField says: \(text)", delegate: nil, cancelButtonTitle: "Okay")
      alert.show()

    })
}
