Crash on reload of empty table if tableView contains tableHeaderView | iOS 10.3.1

[iznv]

On iOS 12 no crashes.

Code to reproduce the issue:

class ViewController: UIViewController {

    private let tableView = UITableView()

    lazy var tableDirector = TableDirector(tableView: tableView)

    override func loadView() {
        view = tableView
    }

    override func viewDidLoad() {
        super.viewDidLoad()

        tableView.tableHeaderView = UIView()

        tableDirector.clear()
        tableDirector.reload()
    }

}
