iOS Swift viewForHeaderInSection Not being Called

Question

I have a UITableview I am trying to add a HeaderView onto my UITableview .

However the viewForHeaderInSection is not being called, but I see the titleForHeaderInSection is being called or is shown. I also tried using a custom cell header for this and it also does not work.

I have no idea what I am doing wrong.

override func viewDidLoad() {
    super.viewDidLoad()

    self.title = "Groceries"

    tableView.registerNib(UINib(nibName: "TransactionSpecifiedCategoriesTableViewCell", bundle: nil), forCellReuseIdentifier: "TransactionSpecifiedCategoriesTableViewCell")
    tableView.registerNib(UINib(nibName: "TransactionSpecifiedCategoriesHeaderViewCell", bundle: nil), forHeaderFooterViewReuseIdentifier: "TransactionSpecifiedCategoriesHeaderViewCell")
    tableView.tableFooterView = UIView(frame: CGRectMake(0, 0, 0, 0))
}

func tableView(tableView: UITableView, viewForHeaderInSection section: Int) -> UIView? {

    let footerView = UIView(frame: CGRectMake(0, 0, tableView.frame.size.width, 100))

    footerView.backgroundColor = UIColor.blackColor()

    return footerView

      //let header: UITableViewHeaderFooterView = view as UITableViewHeaderFooterView
     //var headerView = UIView(frame: CGRectMake(0, 0, 100, 320))
    //headerView.backgroundColor = UIColor.blackColor()
    //        
    //return headerView
}

func tableView(tableView: UITableView, heightForHeaderInSection section: Int) -> CGFloat {
    return 200.0
}

func tableView(tableView: UITableView, titleForHeaderInSection section: Int) -> String? {
    return "First section header title"
}

In swift 3

You should call

func tableView(_ tableView: UITableView, viewForHeaderInSection section: Int) -> UIView? {
        let rect = CGRect(x: 0, y: 0, width: tableView.frame.size.width, height: 44)
        let footerView = UIView(frame:rect)
        footerView.backgroundColor = UIColor.clear
        return footerView
    }
    func tableView(_ tableView: UITableView, heightForHeaderInSection section: Int) -> CGFloat {
        return 44
    }
