I\'m trying to figure out how to add a 1 pixel stroke gray border to my UISearchBar in my app. The Facebook Messenger app accomplishes this quite well. (see pic below).

Easy way to do

    @IBOutlet private weak var searchBar:UISearchBar!{
        didSet{
            if let searchTextfield = self.searchBar.value(forKey: "searchField") as? UITextField  {
                searchTextfield.layer.borderColor = UIColor.lightGray.cgColor
                searchTextfield.layer.borderWidth = 1
                searchTextfield.layer.cornerRadius = 10
            }
        }
    }
