Answer 1

For me the problem was that UISearchController didn't update it's frame when search bar moved upwards. I fixed it by setting frame of UISearchController to the frame of it's presenting view controller.

extension UISearchController {
    open override func viewWillAppear(_ animated: Bool) {
        super.viewWillAppear(animated)
        if let presentingVC = self.presentingViewController {
            DispatchQueue.main.asyncAfter(deadline: .now() + 0.1) {
                self.view.frame = presentingVC.view.frame
            }
        }
    }
}

In viewWillAppear animation of search bar did not start so you have to wait for a split second. When animation starts, frame of presenting VC is set to the correct value and then you can update frame of your UISearchController. The solution is a hack but it works fine for me.
