I am developing an iOS application using Objective-C and I want to use a Swift class (Alert box). I implement the whole function. Without any error I can pass the values. But I am getting the following error message:

"whose view is not in the window hierarchy!"

I've tried different ways:

Method 1

presentViewController(alertController, animated: true, completion: nil)

Method 2

self.presentViewController(alertController, animated: true, completion: nil)

Method 3

var mainView:MainViewController = MainViewController()
mainView.presentViewController(alertController, animated: true, completion: nil)

All methods are resulting the same error message.
