Just to add, I was baffled for WAY longer than I should have been as to why I couldn't refer to the contentView of my cell, when I could quite clearly see it was there. My custom class (using UITableViewCell rather than UITableViewHeaderFooterView) would return a fatal error each time.

You will also need to register the resuableIdentifer like this:

tableView.registerNib(UINib(nibName: "HeaderCell", bundle: nil), forHeaderFooterViewReuseIdentifier: "CellHeader")

Then this bad boy:

    func tableView(tableView: UITableView, viewForHeaderInSection section: Int) -> UIView? {
    let headerCell = tableView.dequeueReusableHeaderFooterViewWithIdentifier("CellHeader") as! CustomHeaderCell!
    return headerCell!.contentView
}
