5,716 PointsHELP 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?

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.
