At what stage of the lifecycle does the creation and configuration of a view in UIViewController occur?

Creating and configuring a view in UIViewController occurs in the lifecycle methods loadView() and viewDidLoad().

• In loadView(), the root view of the controller is usually created and initialized if a storyboard or xib is not used.
• In viewDidLoad(), additional setup of the view takes place after it has been loaded, such as adding subviews, setting properties, and configuring data.

Example:

override func loadView() {
    self.view = UIView()
    self.view.backgroundColor = .white
}

override func viewDidLoad() {
    super.viewDidLoad()
    // Setup subviews
}
