viewForHeaderInSection is called for every section but the first UITableView

Question

I have a UITableView and a UITableViewController which is the delegate of the table view. I have multiple sections in my UITableView, and I need to set a custom header for the first section. Unfortunately, the method override func tableView(tableView: UITableView!, viewForHeaderInSection section: Int) -> UIView! (swift) is being called for every section but section 0 which is the first section. All of my other UITableView delegate and datasource methods are working correctly and I have no methods that should override this method.

Answer 1

From the documentation:

This method only works correctly when tableView:heightForHeaderInSection: is also implemented.
