Cannot query the username from the Parse iOS Swift

Question

im new to iOS and developing twitter like app using tutorials.

people can make tweets from their account. and it get display in home page.

at the moment to home page all the tweets and everything works well except username. im getting nil

this is what i have tried

    override func tableView(tableView: UITableView?, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
            let cell:SpreadTableViewCell = tableView!.dequeueReusableCellWithIdentifier("cell", forIndexPath: indexPath) as! SpreadTableViewCell


            let spread:PFObject = self.LiveFeedData.objectAtIndex(indexPath.row) as! PFObject
            //----------This Content Works fine ----------------
            cell.spreadTextView.text = spread.objectForKey("content") as! String 

            //Spreader
            var findSpreader:PFQuery = PFUser.query()!
            findSpreader.whereKey("objectId", equalTo: spread.objectForKey("spreader")!)


            findSpreader.findObjectsInBackgroundWithBlock{
                (objects:[AnyObject]?, error:NSError?)-> Void in

                if error==nil{
                    let user = (objects as! [PFUser]).last
//but this one giving me nil
                    cell.username.text = user?.username

                }

            }

 return cell
    }

You should do something if error isn't nil - print it, for example. You can simplify your code however, the spreader value in your record is a PFUser, so instead of running a find, you can just read it using fetchInBackgroundWithBlock — Paulw11

Try this:

var user = spread.objectForKey("spreader") as! PFUser
user.fetchIfNeededInBackgroundWithBlock { (obj: PFObject?, error: NSError?) -> Void in
        if obj != nil {
            var fetchedUser = obj as! PFUser
            var username = fetchedUser["username"] as! String
            println(username) 
        }
    }
