show UIAlertController outside of ViewController

Question

I have trouble to display my UIAlertController because I\'m trying to show it in a Class which is not an ViewController.

I already tried adding it:

 var

Create a helper function that you call from the current view controller and pass the current view controller as a parameter:

func showAlertInVC(
  viewController: UIViewController, 
  title: String, 
message: String)
{
  //Code to create an alert controller and display it in viewController
}
