HELP ME! i'm confused by overriding viewDidLoad method

from this code

override func viewDidLoad() { super.viewDidLoad() funFactLabel.text = "An interesting fact!" }

How we can call super.viewDidLoad while we are overriding it?

Jiranan, when you override a function (or method) you are writing a new version, in the subclass, to replace the one inherited from the super class. Here viewDidLoad() is inherited, and being overridden.

Because you don't want to repeat code that is in the super class's version, if you need it you can call that version's code using super.viewDidLoad() -- this is DRY in action.
