Question

self.dismissViewControllerAnimated(true, completion         


        

Answer 1

You have to get the viewController which presented self (current ViewController). If that view controller is rootViewController, then you can use the code below, if not then query it based on your view controller hierarchy.

if let vc3 = self.storyboard?.instantiateViewController(withIdentifier: "vc3") as? ViewController3 {
    let appDelegate = UIApplication.shared.delegate as! AppDelegate
    appDelegate.window?.rootViewController!.present(vc3, animated: true, completion: nil)
}
