However, when the viewWillAppear() method on screen A is called,
I'd like to do something, but how is everyone doing it?

The source code is as follows:

override func viewWillAppear(_animated:Bool){
    presentingViewController?beginAppearanceTransition(false, animated:animated)

    print("viewWillAppear was called.")
}

override func viewDidAppear(_animated:Bool){
    super.viewDidAppear(animated)
    presentingViewController?endAppearanceTransition()
    
    initializeDisplay()
    
    print("viewDidAppear was called.")
}

Thank you in advance.
