TableView didSelect respond issue in Swift

I have a tableView running in my project successfully.But,I have a problem selecting cell and updating my textView which connected to tableview in the same viewController.My textView only updating when i do a long press on tableViewCell.I want to update textView everytime when cell been pressed.I believe,when i pressed the cell deselect itself. My partial code as follow..

Note: I am using the below code in my different projects that works with no issue..I am not sure whats wrong with this tableview....

Thanks in Advance....

  func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
    let CellIdentifier: String = "fontCell"
    let cell: UITableViewCell = tableView.dequeueReusableCellWithIdentifier(CellIdentifier, forIndexPath: indexPath)

     let fontName: String = self.fontName[indexPath.row] as! String

    UIView.animateWithDuration(1, delay: 0, usingSpringWithDamping: 0.3, initialSpringVelocity: 0.5, options: UIViewAnimationOptions.CurveEaseInOut, animations: { () -> Void in 

    cell.textLabel?.text = fontName
    cell.textLabel!.font = UIFont(name: self.fontName[indexPath.row] as! String, size: 25)

    }, completion: nil)

    cell.backgroundColor = UIColor.clearColor()
    cell.textLabel?.textAlignment = .Center
    cell.textLabel?.textColor = UIColor.whiteColor()
    cell.textLabel?.sizeToFit()
    cell.textLabel?.adjustsFontSizeToFitWidth = true
    cell.selectionStyle = .Default

    return cell 
}

    func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {
  //tableView.deselectRowAtIndexPath(indexPath, animated: true)

    dispatch_async(dispatch_get_main_queue(), { () -> Void in
    let fontName: String = self.fontName[indexPath.row] as! String

    self.textView.font = UIFont(name: fontName, size: 20)
  })

}

didSelectRowAtIndexPath should already be called on the main thread so removing the dispatch_async and just running the code like this should be fine

func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {
    let fontName: String = self.fontName[indexPath.row] as! String
    self.textView.font = UIFont(name: fontName, size: 20)
}

If you've added a gesture recognizer to your tableView to handle long press (or something else) that might be interfering with your other taps. try setting cancelsTouchesInView to false on your recogniser. 

tapGestureRecognizer.cancelsTouchesInView = false
