My table view doesnt show section 0 header, other sections headers are showing as expected, Any ideas?

let headerLabels = ["Assigned", "Not Assigned","Archived"]



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

    let headerLabel = UILabel()

    headerLabel.textColor = UIColor.white

    headerLabel.textAlignment = .center

    headerLabel.text = headerLabels[section]

    return headerLabel

}



func numberOfSections(in tableView: UITableView) -> Int {

    return headerLabels.count

}
