Explain the difference between viewdidload and viewdidappear?

Answer Posted / Abhishek Rajput

viewDidLoad is a method that gets called when a view controller's view is loaded into memory for the first time. It's used to perform one-time setup tasks, like setting up initial UI elements. viewDidAppear is called every time the view controller becomes visible on the screen after being hidden (e.g., by switching between view controllers or rotating the device). It's useful for updating UI elements that may have been affected by changes in other view controllers.
