Programatically change size of UIView that is on Storyboard

Question

I am attempting to change the size of a UIView that I have placed in the Storyboard. For some reason the size does not change but remains the same as drawn on the Storyboard. I have not hooked up Autolayout so this cannot be the reason it remains the same. My code:

@IBOutlet weak var courseView: CourseView!  // CourseView is a UIView

override func viewWillAppear(animated: Bool) {
    courseView.frame = CGRectMake(0, 0, 200, 200)  // This is just to test!
}

I have also done the same in viewDidLoad() but without success. Any ideas?

Acording to this answer

The methods viewWillAppear: and viewDidLoad: have no layout information. Any layout changes made here will be lost when viewDidLayoutSubviews: is called later on.

If you are using auto layout you cant change the constraints at any point, but the actual change will happen @ viewDidLayoutSubviews:

If you are not using auto layout you need to update the layout @ viewDidLayoutSubviews: or after the view is being presented (@ viewDidAppear: or by user input)
