Answer 1

I think that the solution is to add the Search Bar in the Navigation Bar:

navigationController?.navigationBar.prefersLargeTitles = true // Navigation bar large titles
navigationItem.title = "Contacts"
navigationController?.navigationBar.largeTitleTextAttributes = [NSAttributedStringKey.foregroundColor : UIColor.white]
navigationController?.navigationBar.barTintColor = UIColor(displayP3Red: 0/255, green: 150/255, blue: 136/255, alpha: 1.0)

let searchController = UISearchController(searchResultsController: nil) // Search Controller
navigationItem.hidesSearchBarWhenScrolling = false
navigationItem.searchController = searchController
