Dismissing presented view controller won't work

Question

I've got a kind of complicated modal segue setup in my project. I'm trying to dismiss a view controller another view controller previously presented. I'm doing so with this code:

if(self.presentedViewController != nil){
    print(self.presentedViewController!)
    self.presentedViewController!.dismiss(animated: false)
    print(self.presentedViewController!)
}

The print s are there for debugging purposes. They show that the presentedViewController doesn't actually get closed. Even though I've set animated to false, I still see an animation occuring in the app when dismiss is called. Yet, the VC doesn't actually get dismissed. Anyone knows a solution?

The presenting view controller is responsible for dismissing the view controller it presented. If you call this method on the presented view controller itself, UIKit asks the presenting view controller to handle the dismissal.

dismiss(animated:completion:) dismisses the view controller that was presented modally by the view controller.

If you present a view controller from the app's root, for example:

Presenting view controller

let root = UIApplication.shared.keyWindow!.rootViewController!
root.present(someViewController, animated: true, completion: nil)

You would dismiss it from the presented view controller like so:

Presented view controller

let root = UIApplication.shared.keyWindow?.rootViewController
root?.dismiss(animated: true, completion: nil)
