Swift 3 snippet

override func viewDidLayoutSubviews() {
    super.viewDidLayoutSubviews()

    if let scrollView = view.subviews.filter({ $0 is UIScrollView }).first,
        let pageControl = view.subviews.filter({ $0 is UIPageControl }).first {
        scrollView.frame = view.bounds
        view.bringSubview(toFront:pageControl)
    }
}
