            button.layer.cornerRadius = 4
        }

        searchController.barBackgroundColor = UIColor(hex: 0xF9F9FA)
        
        searchController.leftIcon = UIImage(named: "football")
        searchController.leftIconColor =  UIColor(hex: 0xEE7F79)
        searchController.setRightBookmarkIcon(image: UIImage(named: "speaker"), color: UIColor(hex: 0xEE7F79), for: [UIControlState.normal])
        searchController.setRightClearIcon(image: UIImage(named: "x"), color: UIColor(hex: 0xEE7F79), for: [UIControlState.normal])
        
        searchController.cursorColor = UIColor(hex: 0x333333)
        searchController.textFieldTextColor = UIColor(hex: 0xbbbbbb)
        searchController.hideBorderLines = true
        searchController.textFieldBackgroundColor = UIColor(hex: 0xF9F9FA)
        
        searchController.searchTextDidChange = { searchBar, text in
            print("Keyword: \(text)")
        }
    }
    
    override func viewDidAppear(_ animated: Bool) {
        super.viewDidAppear(animated)
        // Do the settings here. Some settings could be unavailable otherwise.
        setupSearchController()
    }

The delegate methods of UISearchBar has been convert to closures like below

typealias EmptySearchBarHandler = (UISearchBar)->()
typealias BoolSearchBarHandler = (UISearchBar)->(Bool)

public var searchButtonClickHandler: EmptySearchBarHandler?
public var searchBarShouldBeginEditingHandler: BoolSearchBarHandler?
public var searchBarShouldEndEditingHandler: BoolSearchBarHandler?
public var searchBarCancelButtonClickHandler: EmptySearchBarHandler?

public var searchTextDidChange: ((UISearchBar, String)->())?
public var searchTextShouldChangeInRange: ((UISearchBar, NSRange, String)->(Bool))?

So set it up like this

searchController.searchTextDidChange = 
{ searchBar, text in
        print("Content: \(text)")
}
