You can use 'includeKey' to access pointer values of related classes

findTimeLineDataQuery.includeKey("sender")

findTimeLineDataQuery.findObjectsInBackgroundWithBlock({
    (objects : [AnyObject]?, error : NSError?) in

    if let objects = objects where error == nil {

        var chats:(timelinechatsData: [String], chatsDate: [NSDate]) = ([], []) //date might be NSDate
        var message: (messageObjts: [String], messageSender: [String]) = ([], [])

        var datesToString: [String] {
             get {
                 var stringDates:[String] = []
                 let formatter = NSDateFormatter()
                 formatter.dateFormat = "dd-MM-yyyy" //change the format as you wish
                 for date in dates {
                     stringDates.append(formatter.stringFromDate(date))
                 }
                 return stringDates
             }
        }

        for singleObject in objects {

            if let user = singleObject["sender"] as! PFObject {
                let first_name = user["first_name"] as! String
                let last_name = user["last_name"] as! String

                //Cast it to how you saved it. I can't see it from the picture so I assumed you saved it as NSData
                let picture = user["picture"] as! NSData
                picturesProfilesArray.append(picture)
                //once you fetch the user data, you can save it in a dictionary or however you want and later call it from cellForRowAtIndex
            }



            if let stringData = singleObject["message"] as? String {

                chats.timelinechatsData.append(stringData)

                if let messageDate = singleObject.createdAt {
                    chats.chatsDate.append(messageDate)
                }
            }

            //new
            if let messageObject = singleObject["messageObject"] as? String {
                message.messageObjts.append(messageObject)
            }

            //new senderNickname
            if let messageSender = singleObject["senderNickname"] as? String {
                message.messageSender.append(messageSender)
            }
        }

        //update self
        dispatch_async(dispatch_get_main_queue()) {

            self.timelineChatsDataArray += chats.timelinechatsData
            self.chatsDateArray += datesToString
            self.messageObjectArray += message.messageObjts
            self.messageSenderArray += message.messageSender

            self.tableView.reloadData()
        }
    }
})
