How to create a pop-up alert once the view loads in xcode

I need a simple alert that pops up when the view loads on the screen. I've found a couple of tutorials on how to create a pop-up alert but they all require that a UIbutton is pressed. I need it to just automatically pop up when the view loads.

This is a start to my code, however I can't figure out how to call upon the code without having to use a UIbutton action: 

    override func viewDidLoad() {
    super.viewDidLoad()

    let alertController = UIAlertController(title: "Disclaimer", message:
        "Hello, world!", preferredStyle: UIAlertControllerStyle.Alert)
    alertController.addAction(UIAlertAction(title: "Accept", style: UIAlertActionStyle.Default,handler: nil))

    self.presentViewController(alertController, animated: true, completion: nil)

The problem is that "load" does not mean "on the screen". You are conflating two different things. viewDidLoad merely means that the view controller has a view. The view does not appear on the screen until viewDidAppear:. So that's the place to put this code.
