Swift 5.2

you can use this code for your requirment

 override func viewDidLayoutSubviews() {
    super.viewDidLayoutSubviews()

    if let myScrollView = view.subviews.filter({ $0 is UIScrollView }).first,
        let myPageControl = view.subviews.filter({ $0 is UIPageControl }).first {
        myScrollView.frame = view.bounds
        view.bringSubviewToFront(myPageControl)
    }
}
