Useful UISearchBar Extensions

If you want to access the TextField inside the UISearchBar and want to set the properties

extension UISearchBar{
    public var textField: UITextField? {
        let subViews = subviews.flatMap { $0.subviews }
        guard let textField = (subViews.filter { $0 is UITextField }).first as? UITextField else {
            return nil
        }
        return textField
    }
}

extension UISearchBar{

public var textField: UITextField? {

let subViews = subviews.flatMap { $0.subviews }

guard let textField = (subViews.filter { $0 is UITextField }).first as? UITextField else {

return nil

}

return textField

}

If you want to remove the whitespaces and newline character from UISearchBar
