indexPathForRowAtPoint Error in a TableViewCell in Swift

Question

Inside a button of a UITableViewCell, I have this function, that creates an automatic scroll to the next cell.

var tableView = self.superview?.superview

    let point = sender.convertPoint(CGPointZero, toView : tableView)
   let indexPath = tableView.indexPathForRowAtPoint(point)!

    if indexPath.row < tableView.numberOfRowsInSection(indexPath.section) {
        let newIndexPath = NSIndexPath(forRow:indexPath.row + 1, inSection:indexPath.section)
        tableView.scrollToRowAtIndexPath(
            newIndexPath, atScrollPosition:.Top, animated: true)
    }

I have an error on the line: "let indexPath = tableView.indexPathForRowAtPoint(point)!" saying: "Type of expression is ambiguous without more context"

Do you have any idea how to fix it? I would like to keep that code inside my UITableViewCell.

Many thanks

Cast the value returned by superview

var tableView = self.superview?.superview as! UITableView
