TableView NSException

Question

I am new to Swift , I am parsing my JSON by using ObjectMapper but I want data to be displayed in TableView. But I have a problem:

libc++abi.dylib: terminating with uncaught exception of type NSException

I get it after the method numberOfRowsInSection. My array is not nil, array has a 2193 elements I do not understand why it happened

It my code for parsing JSON :

   let timeStamp = NSNumber(value: Date().timeIntervalSinceNow)

    var programs = [PrograToDayModel]()

    override func viewDidLoad() {
        super.viewDidLoad()

        super.viewDidLoad()
        let timeStamp = NSNumber(value: Date().timeIntervalSinceNow)
        self.downloadPrograms(for: timeStamp)

    }

    func downloadPrograms(for timestamp: NSNumber) {

        Alamofire.request("http://52.50.138.211:8080/ChanelAPI/programs/\(timestamp)").responseArray { (response: DataResponse<[PrograToDayModel]>) in

            let programlArray = response.result.value

            if let programlArray = programlArray {
                for program in programlArray {

                    self.programs.append(program)
                    print(program.title as Any)
                }


            }
            DispatchQueue.main.async {
                self.tableView.reloadData()
            }
        }
    }

it good i print element in console :

my code for table:

    // MARK: - Table view data source

    override func numberOfSections(in tableView: UITableView) -> Int {
        // #warning Incomplete implementation, return the number of sections
        return 1
    }

    override func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
        // #warning Incomplete implementation, return the number of rows
         print(self.programs.count as Any)
        return self.programs.count

    }


    override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
        let cell = tableView.dequeueReusableCell(withIdentifier: "ProgramTableViewCell", for: indexPath) as! ProgramTableViewCell

        cell.title.text = self.programs[indexPath.row].title

        return cell
    }
}

All identifiers in place I using tab bar, tableView, tableViewCell How can I solve this problem?

To identify the issue, you can just try this -

it might be a reason for that issue

So go to Main.storyboard, and right-click on View Controller at the top of the phone outline and remove any outlets with yellow flags (if any).
