UISearchBar Height Automatic Size Change Swift

Question

Here is what I am trying to do:

original image

The screenshot is taken from iPhone:

second image

I'm working on a simple app and adding a programatically UISearchbar but I am really confused about why shows extra space from the top like the second image. but when I write the UISearchbar changes our position like the first image.

This is my code:

let searchController = UISearchController(searchResultsController: nil)

override func viewDidLoad() {
    super.viewDidLoad()
    
 self.searchController.obscuresBackgroundDuringPresentation = false
 self.searchController.searchBar.placeholder = "Search"
 self.searchController.searchBar.barStyle = .black
 self.searchController.searchBar.delegate = self
 self.definesPresentationContext = true
 if #available(iOS 11.0, *) {
 navigationItem.searchController = searchController
    } else {
        // Fallback on earlier versions
        navigationItem.titleView = searchController.searchBar
    }
   }

extension starControl: UISearchBarDelegate{

func searchBarTextDidBeginEditing(_ searchBar: UISearchBar){
    //Show Cancel
    searchBar.setShowsCancelButton(true, animated: true)
    searchBar.tintColor = .black
}

func searchBar(_ searchBar: UISearchBar, textDidChange searchText: String){

}

func searchBarSearchButtonClicked(_ searchBar: UISearchBar){
    searchBar.setShowsCancelButton(false, animated: true)
    searchBar.resignFirstResponder()
    guard let term = searchBar.text , term.isEmpty == false else{
        return
    }
}

func searchBarCancelButtonClicked(_ searchBar: UISearchBar){
    searchBar.setShowsCancelButton(false, animated: true)
    searchBar.text = String()
    searchBar.resignFirstResponder()
 }
}

Can someone please explain to me how to solve this, I've tried to solve this issue but no results yet.

Any help would be greatly appreciated.

Thanks in advance.

This is latest swift4.2 code and latest functionality of search bar just put this function in controller and call from viewDidLoad.

func setupNavBar() {
        self.title = "Controller title"
        self.navigationController?.navigationBar.prefersLargeTitles = false
        self.navigationController?.navigationItem.largeTitleDisplayMode = .always
        let searchController = UISearchController(searchResultsController: nil)
        searchController.searchBar.delegate = self
        navigationItem.searchController = searchController
    }

You can't remove height because it's for a title, can you add navigation bar title? – Abhishek Jadhav Dec 26 '18 at 12:58
This is the newest implementation by apple, you can add a title as large or small, or Let me check is there any solution! – Abhishek Jadhav Dec 26 '18 at 13:07
