Prepare for segue delay. Information is lagging but being presented

I'm pushing otherUserUid and otherUserFullName to another view controller but it isn't being call immediately. The information is lagging behind and it takes 2 clicks for the information to appear.

I think preparForSegue: is being called before didSelectRowAtIndexPath: Any solutions how to fix this?

Cheers!

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

    self.performSegueWithIdentifier("jsqDirectory", sender: self)
    let indexPath = tableView.indexPathForSelectedRow!

    let currentCell = tableView.cellForRowAtIndexPath(indexPath)! as UITableViewCell

    self.otherUserFullName = (currentCell.textLabel?.text)!
    print(self.otherUserFullName)

    self.otherUserUid = (currentCell.detailTextLabel?.text)!
    print(self.otherUserUid)

}

override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
    if segue.identifier == "jsqDirectory" {
        if let viewController = segue.destinationViewController as? JSQViewController{

            viewController.senderDisplayName = self.fullName
            viewController.senderId = self.firebase.authData.uid

            viewController.otherUid = self.otherUserUid
            viewController.otherUser = self.otherUserFullName
        }
    }
}

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

    let cell = tableView.dequeueReusableCellWithIdentifier("directoryCell") as UITableViewCell!
    let directoryItem = items[indexPath.row]

    cell.textLabel?.text = directoryItem.fullName
    cell.detailTextLabel!.text = directoryItem.key
    cell.detailTextLabel!.hidden = true

    return cell
}

in didSelectRowAtIndexPath you have to perform segue at the end of Function like thiss..

let indexPath = tableView.indexPathForSelectedRow!

let currentCell = tableView.cellForRowAtIndexPath(indexPath)! as UITableViewCell

self.otherUserFullName = (currentCell.textLabel?.text)!
print(self.otherUserFullName)

self.otherUserUid = (currentCell.detailTextLabel?.text)!
print(self.otherUserUid)
self.performSegueWithIdentifier("jsqDirectory", sender: self)
