Since a subclass of NSObject has no navigation capability , you need to either

1- Use a delegate by adding this var

weak var myController:VCName?

and init it whenever you want ( before the usage so the navigation will function ) then use

myController?.present(anotherVC,animated:true)

2- Use Application's rootVC ( but note it may be presenting another vc at that time so it may/not function as this depends on your navigation structure )

UIApplication.shared.keyWindow?.rootViewController?.present..........
