Long Press Gesture Recognizer Only Fired When Finger is Lifted

I'm having an interesting problem with a long press gesture recognizer. I placed one of these on a UITableView, and it only works when I lift my finger after the long press. So basically, I would place my finger on a cell, and then when I lift my finger, it triggers the long press. I figured this out by putting printns when the long press began and ended and both fire after I lift my finger. I think the tableViews default panGestureRecognizer might be interfering with the longPressGestureRecognizer. Here is my code in viewDidLoad:

    var longPress:UILongPressGestureRecognizer = UILongPressGestureRecognizer(target: self, action: "handleLongPress:")
    longPress.minimumPressDuration = 0.06
    longPress.delegate = self
    self.tableView.addGestureRecognizer(longPress)
    longPress.requireGestureRecognizerToFail(self.tableView.panGestureRecognizer)

Touching down in the cell will not cause the table view's panGestureRecognizer to fail, so delete the requireGestureRecognizerToFail method, and you should then get to the .Began state while your finger is still down.
