title: Swift - UISearchController SearchBar Bug - False position after focusing
body: <p>I have a ViewController with a TableView. On viewDidLoad I create a UISearchController and set the search bar in the header of this tableview. At beginning it is all normal, but if I focused the search bar and unfocused it, the searcher is in a false position. It overlaps like 10px of the first table view cell. The 2 pictures after explained it. In the first picture before touching the search bar. And in the second picture after touching and unselecting it.</p>
