How to put the UIPageControl element on top of the sliding pages within a UIPageViewController?

by

I didn’t have the rep to comment on the answer that originated this, but I really like it. I improved the code and converted it to swift for the below subclass of UIPageViewController:

class UIPageViewControllerWithOverlayIndicator: UIPageViewController {
    override func viewDidLayoutSubviews() {
        for subView in self.view.subviews as! [UIView] {
            if subView is UIScrollView {
                subView.frame = self.view.bounds
            } else if subView is UIPageControl {
                self.view.bringSubviewToFront(subView)
            }
        }
        super.viewDidLayoutSubviews()
    }
}

Clean and it works well. No need to maintain anything, just make your page view controller an instance of this class in storyboard, or make your custom page view controller class inherit from this class instead.
