防止 UISearchBar 在 UITableView 中滚动时隐藏（滚动时保持 UISearchBar 显示）-Swift，Xcode

Question

I currently have a UISearchBar (code below) which works fine however I'm trying to make it so upon scrolling in my UITableView, my UISearchBar does not disappear. One of the things I've read is to embed a searchController into a view controller with the following line of code: navigationItem.searchController = yourSearchController and then to prevent the UISearchBar from hiding, add this line of code: navigationItem.hidesSearchBarWhenScrolling = false however it has not worked. I've also read to put the SearchBar above the UITableView in the View Hierarchy, but when I do that and place it below the Navigation Bar, upon scrolling it overlaps the tableView cells. Do I need a SearchController, and if so, how do I implement this? I've spent hours searching through similar StackOverflow threads with the same question asked many years ago and have attempted to implement the responses, however, none of the responses have worked. Any response would be greatly appreciated, thanks!

UISearchBar IBOutlet:

@IBOutlet weak var searchBar: UISearchBar!

viewDidLoad Func:

filteredData = data

UISearchBar Code:

func searchBar(_ searchBar: UISearchBar, textDidChange searchText: String) {
   if searchText.isEmpty {
      filteredData = data
   } else {
      filteredData = data.filter{$0.title.range(of: searchText, options: .caseInsensitive) != nil }
   }
   self.tableView.reloadData()
}
}

View Hierarchy:

View Controller Layout:

What if you create a UISearchController as a variable:

let searchController = UISearchController(searchResultsController: nil)

and then on viewDidLoad

navigationItem.titleView = searchController.searchBar 

The difference here is that your seachBar is embedded on the title of the navigationItem, so it won't disappear on scrolling. This shows the behavior you are looking for.
