lazy var searchController: UISearchController = {
    let searchController = UISearchController(searchResultsController: nil)
    searchController.searchBar.placeholder = "Search"
    searchController.hidesNavigationBarDuringPresentation = false
    searchController.searchResultsUpdater = self
    searchController.searchBar.delegate = self
    return searchController
}()

func setUpNavigationItem() {
    navigationItem.title = "Search"
    navigationItem.searchController = searchController
    navigationItem.hidesSearchBarWhenScrolling = true

    let loginButton = UIBarButtonItem(title: "Login", style: .plain, target: nil, action: nil)
    loginButton.tintColor = .label
