I prefer a generic way to do it.

I have this extension for the UINavigationController :

extension UINavigationController {

   func backToViewController(vc: Any) {
      // iterate to find the type of vc
      for element in viewControllers as Array {
         if "\(element.dynamicType).Type" == "\(vc.dynamicType)" {
            self.popToViewController(element, animated: true)
            break
         }
      }
   }

}

Let's say I have a FOHomeVC class (who is a UIViewController) instantiated in the navigation stack.

So I would do this in my code:

self.navigationController?.backToViewController(FOHomeVC.self)
