Programmatic UI: don't call super.loadView but do call super.viewDidLoad?

This question pertains to programmatic-only apps that don't use nib files where the storyboard has been removed and the window is created and given a root view in the app delegate. Some of the accepted answers I've read here appear to conflict with Apple's documentation, so tell me if this is correct:

When creating a UIViewController, the methods that create its foundation should be placed in loadView without calling super.loadView:

override func loadView() {

    // build something
    buildSomething()

}

And the methods that make the final touches should be placed in viewDidLoad with calling super.viewDidLoad:

// view did load
override func viewDidLoad() {
    super.viewDidLoad()

    // arrange something that requires it be built first
    arrangeSomething()

}

Or should super.viewDidLoad() be called only in special situations? If so, what are they?

This is correct, that if you implement loadView you should not call super. As the documentation says:

Your custom implementation of this method should not call super.

But if you implement viewDidLoad, you should always call super.
