In which method of the UIViewController class is it recommended to implement the setup of the displayed view?

To configure the displayed view in a UIViewController class, it is recommended to use the viewDidLoad() method.

This method is called after the controller has loaded its view into memory and is an appropriate place for initializing the interface, configuring elements, setting delegates, and other operations related to preparing the UI.

Example:

override func viewDidLoad() {
    super.viewDidLoad()
    // Configure interface elements
    view.backgroundColor = .white
    setupSubviews()
}

Using viewDidLoad() is better than init or loadView() because in viewDidLoad() the view is guaranteed to be loaded, and you can safely work with its elements.
