What are the main stages in the lifecycle of a ViewController in iOS?

The main stages of the ViewController lifecycle in iOS include:

• loadView() — loading or creating the controller's root view.
• viewDidLoad() — called after the view has been loaded, typically used to initialize data and set up the UI.
• viewWillAppear(_:) — called before the view appears on the screen, can be used to update the UI.
• viewDidAppear(_:) — called after the view has appeared, suitable for starting animations or loading data.
• viewWillDisappear(_:) — called before the view disappears, can be used to save state.
• viewDidDisappear(_:) — called after the view has disappeared, can be used to stop processes.
• deinit — resource cleanup when the controller is deallocated.

These methods allow managing the state and resources of the ViewController at different times in its lifecycle.
