Why is it recommended to initiate animations in the viewDidAppear method instead of other lifecycle methods?

The viewDidAppear method is called after the view has fully appeared on the screen and is visible to the user. It is recommended to initiate animations here for several reasons:
- In
viewDidLoadorviewWillAppear, the view has not yet been displayed, and animations may not be visible or may look incorrect. - In
viewDidAppear, it is guaranteed that all interface elements are loaded and ready for display, ensuring smooth animations. - If animations are started too early, the user might miss them or see flickering.
Therefore, viewDidAppear is the optimal place to start animations so that they are noticeable and look natural.
