You can not present two view controllers at the same time from the same source controller. Instead, try presenting the second view controller from the first one that was presented.

       if let presented = self.presentedViewController {
            presented.present(vcToPresent, animated: true, completion: nil)
        }
        else {
            self.present(vcToPresent, animated: true, completion: nil)
        }
