Why/when do we have to call super.ViewDidLoad?

Question

Everyone tells me \"Use super.viewDidLoad() because it\'s just like that\" or \"I\'ve been doing it always like that, so keep it\", \"It\'s wrong if you don\'t call super\",

Answer 1

I have a secret, when I worked at Apple I read the source code for UIKit, partly to answer questions I had like this, viewDidLoad is empty in all the UI*ViewController classes.

Naturally I am not there anymore, they may have changed this.
