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) 
        }
    }
