After I checked your sample project:

You didn't did anything wrong, but referring to viewForFooterInSection, it will not get called until you implement heightForFooterInSection method:

func tableView(_ tableView: UITableView, heightForFooterInSection section: Int) -> CGFloat {
    return 50 // for example
}

Similar Cases:

No implementing for heightForHeaderInSection ==> No calling for viewForHeaderInSection even if it's implemented.

Returning numberOfRowsInSection as zero ==> No calling for cellForRowAt even if it's implemented.

Additional Note: you don't have to add tableView.dataSource = self and tableView.delegate = self in viewDidLoad(), they have been set in the interface Builder.
