Swift - Retrieving information stored in custom tableview-cells

I've implemented the longPressGesture in my custom cells, and now I need to retrieve the information that is stored in these cells.

My cellForRowAtIndexPath-function looks like this:

func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell{

    let longPress: UILongPressGestureRecognizer = UILongPressGestureRecognizer(target: self, action: "cellLongPressed:")
    longPress.delegate = self
    longPress.minimumPressDuration = 1
    longPress.numberOfTouchesRequired = 1

    let cellID = "cell"
    var mcell:CusCell = self.tv.dequeueReusableCellWithIdentifier("cell") as CusCell

    mcell.addGestureRecognizer(longPress)

    let data = mainList[indexPath.row] as SecondModel

    var dateStr:String = String()
        dateStr = printDate(data.date)

        mcell.mainLabel.text = data.receiver
        mcell.recLabel.text = "Message sent at \(dateStr)"
        mcell.imageLabel.image = UIImage(named: icons[0])
        mcell.messType = messageType

return mcell }

My didSelectRowAtIndexPath-function looks like this:

func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {

    let selectedCell: CusCell = tv.cellForRowAtIndexPath(indexPath) as CusCell

    messagType = selectedCell.messType

    println(messagType)

}

My cellLongPressed-function looks like this:

func cellLongPressed(gestureRecognizer:UIGestureRecognizer) {

    if (gestureRecognizer.state == UIGestureRecognizerState.Ended) {
        println("STATE ENDED")
        //Do Whatever You want on End of Gesture
    }
    else if (gestureRecognizer.state == UIGestureRecognizerState.Began){
        println("STATE BEGAN")
        //Do Whatever You want on Began of Gesture
    }
}

Now as you probably can guess, the integer stored in "selectedCell.messType" never gets printed. I don't really understand why this shouldn't work, is my declaration of the "selectedCell" wrong?

Any suggestions would be appreciated.

Why can't you read the data back from the model if messageType is part of the model? Reading the data back from the cell is not a good way to do it.

func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath)  {

    let data = mainList[indexPath.row] as SecondModel
    var messagType = data.messageType
    println(messagType)

}

If its you want to log the values inside long press event

func cellLongPressed(gestureRecognizer:UIGestureRecognizer) {

    if (gestureRecognizer.state == UIGestureRecognizerState.Ended) {
        var point = gestureRecognizer.locationInView(self.tableView)
        if let indexPath = self.tableView.indexPathForRowAtPoint(point)
        {
            let data = mainList[indexPath.row] as SecondModel
            var messagType = data.messageType
            println(messagType)
        }
    }
    else if (gestureRecognizer.state == UIGestureRecognizerState.Began){

    }
}
