In Xcode8, or latest Swift version, the method signature has been changed. This change might be causing your code to not call delegate method.

Fix it by writing method again using autocomplete.

func tableView(tableView: UITableView, heightForHeaderInSection section: Int) -> CGFloat {
    return 50.0
}

heightForHeaderInSection has to be used while using viewForHeaderInSection.
