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?

There must be a reason mention in the debugger. Please share that as well. — Umair Afzal, Feb 02 '17 at 11:23
There should be more information in the debugger about that NSException. It should help. — Larme, Feb 02 '17 at 11:23
@Umair Afzal thats all : warning: could not load any Objective-C class information. This will significantly reduce the quality of type information available. and my print and libc++abi.dylib: terminating with uncaught exception of type NSException — , Feb 02 '17 at 11:26

Please make a breakpoint in `tableView(_: cellForRowAt indexPath:)` and check the return value of `dequeueReusableCell`. See if cell is not nil and if cell.text is initialized as well. — kiecodes, Feb 02 '17 at 11:35
@Kie tableView(_: cellForRowAt indexPath:) this method is not called — , Feb 02 '17 at 11:41
Can you try to set a breakpoint for the exceptions. Maybe we can get more information this way: http://stackoverflow.com/a/17802723/389007 — kiecodes, Feb 02 '17 at 11:43
@Kie AppDelegate signal SIGABRT and console libc++abi.dylib: terminating with uncaught exception of type NSException (lldb) I dont found error — , Feb 02 '17 at 11:57
Too little exception info there. Have you set "OS_ACTIVITY_MODE" environment variable to 'disable'? — Daniyar, Feb 02 '17 at 12:00
In cellForRowAt method - Look at second line code. Create the iboutlet with different name [dont take as title]. Try it. or change ProgramTableViewCell to UItableViewCell. — Pavankumar, Feb 02 '17 at 12:46
@koen I found error : error in __connection_block_invoke_2: Connection interrupted — , Feb 02 '17 at 17:30

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).

Do this and build the connection again to the viewController. Mine works by doing it. – Firda Sahidi Nov 14 '18 at 06:56

I was getting a similar non descriptive error when trying to initialize a uitableviewcontroller when trying to add a section/number of rows. Did you register a tableview cell class? I see that you have a custom tableview cell created, so if that isn't registered with your tableview that might be causing this error.

   tableView.register("ProgramTableViewCell".self, forCellReuseIdentifier: "ProgramTableViewCell")

TableView NSException
