Swift solution

Create two outlets, one for your view and one for your scroll view:

@IBOutlet weak var myView: UIView!
@IBOutlet weak var scrollView: UIScrollView!

Then in your viewDidLayoutSubviews you can add the following code:

let scrollSize = CGSize(width: myView.frame.size.width, 
                        height: myView.frame.size.height)
scrollView.contentSize = scrollSize

What we've done is collected the height and width of the view and set the scrollViews content size to match it. This will stop your scrollview from scrolling horizontally.

More Thoughts:

CGSizeMake takes a width & height using CGFloats. You may need to use your UIScrollViews existing height for the second parameter. Which would look like this:

let scrollSize = CGSize(width: myView.frame.size.width, 
                        height: scrollView.contentSize.height)
