UITableView footer not found correctly

Question

I want to keep my floating footer UITableView.

I did it right, but my problem is that the footer does not display everything, I need to scroll it a bit to figure it out. I do not know why.

Please look, the footer just shows the top black, not black:

Where do I have the upper and lower black bars in the interface builder

I am adding a footer as follows:

override func tableView(tableView: UITableView, viewForFooterInSection section: Int) -> UIView? {
        return self.footerView
    }
