Adding Notification for DismissViewController without Subclassing

Question

I have a ViewController that I am presenting currently.

So lets say VC2 is being presented on VC1. Without Subclassing VC2 is there a way to be notified on VC1 that VC2 got dismissed? I don't want to create a subclass of ViewController just to acknowledge the dismissal of the ViewController for tracking purpose.

Thanks.

On `VC2`, you can get `VC1` by using `self.presentingViewController` and do whatever you want. — trungduc, Apr 24 '18 at 18:10

You can try in VC1

var count = 0

 override func viewWillAppear(_ animated:Bool) {
   super.viewWillAppear(animated)
   count+=1

    if(count == 2) {
       // dismiss of VC2
    }

 }
