  searchController.searchResultsUpdater = self

Answer 1

All you need to do is to hide and display your search bar when you start scrolling so for that you need to override the didBeginScrolling (check the exact name ) and add this code accordingly

navigationItem.hidesSearchBarWhenScrolling = false
