How to make a searcher behave like a searchController?

Hey guys, on Stackoverflow I read a bit about the differences between UISearchBar and UISearchController. I already created the GUI of my Project and I'm absolutely in love with it, the problem is that I am using a Searchbar and of course I could change that to a SearchController but I don't want it to be in the navigation bar. So what and HOW I have to implement to make my Searchbar behave and usable like a SearchController? Thanks in advance
