viewWillDisappear()
viewDidDisappear()

Explanation :

The View Controller Life Cycle in Swift consists of several key methods that are automatically called by the system at different stages of the view controller's life cycle. These methods are as follows:

viewDidLoad() - This method is called when the view controller is first loaded into memory. It is typically used to initialize the view controller's properties and set up any initial UI.

viewWillAppear() - This method is called just before the view controller's view is about to appear on the screen. It is typically used to update the UI based on any changes that may have occurred since the view was last displayed.

viewDidAppear() - This method is called when the view controller's view has been added to the screen. It is typically used to start any animations or other time-sensitive tasks that should begin when the view appears.

viewWillDisappear() - This method is called just before the view controller's view is about to be removed from the screen. It is typically used to clean up any resources that were used by the view controller.

viewDidDisappear() - This method is called when the view controller's view has been removed from the screen. It is typically used to stop any animations or other time-sensitive tasks that were started in viewDidAppear().
