I finally worked out my own solution to this problem because in my case I couldn't use the view controller's life cycle. Create your own scroll view subclass and use it instead of UIScrollView. This even worked for a scroll view inside a collection view cell.

 class MyScrollView:UIScrollView {

    var myContentSize:CGSize = CGSize.zero  // you must set this yourself 

    override func layoutSubviews() {
       super.layoutSubviews()
       contentSize = myContentSize
    }

 }

My MyScrollView was defined in the nib with a tag of 90. If so this is a good way to set content size in the code in the parent view.

let scrollView = viewWithTag(90) as! MyScrollView      
scrollView.myContentSize = ...
