I have a UITableViewcontroller setup with just two cells. The footer text is displaying over the last cell.

Strangely I have other controllers with practically the same setup and code and where the footer is showing as expected.

I have tried tried changing the style group / inset etc.

Any ideas appreciated. Thanks

CodePudding user response：

You should set a height on your footer view. You can do this by calling tableView(:heightForFooterInSection:) and returning UITableView.automaticDimension.

As you are inheriting from UITableViewController you can do it in the following way

override func tableView(_ tableView: UITableView, heightForFooterInSection section: Int) -> CGFloat {
    UITableView.automaticDimension
}

This will give you the following result:
