iOS UISearchController UITableView iOS17 Swift

I'm optimizing some code but I'm experiencing an unexpected issue with UISearchController in my UITableViewController. After implementing the search controller, I've noticed that the search bar disappears when I scroll up too quickly or when the keyboard is dismissed. I have set `hidesNavigationBarDuringPresentation` to `true`, but it seems to still flicker and sometimes remain hidden. Here’s the relevant code snippet where I set up the search controller: ```swift class MyTableViewController: UITableViewController, UISearchResultsUpdating { var searchController: UISearchController! override func viewDidLoad() { super.viewDidLoad() setupSearchController() } func setupSearchController() { searchController = UISearchController(searchResultsController: nil) searchController.searchResultsUpdater = self searchController.obscuresBackgroundDuringPresentation = false searchController.searchBar.placeholder = "Search items" navigationItem.searchController = searchController definesPresentationContext = true } func updateSearchResults(for searchController: UISearchController) { // Implement search logic here } } ``` I've tried adjusting the `definesPresentationContext` property, but it doesn’t seem to resolve the issue. Additionally, I confirmed that the search bar is not being dismissed because of some additional gesture recognizers or custom navigation actions. I also checked the constraints and layout of the table view, and everything appears to be set up correctly. Has anyone encountered similar issues with UISearchController in a UITableViewController, especially on iOS 17? Any insights or suggestions would be greatly appreciated! Cheers for any assistance!
