TableView doesn't show my Data from Realm

i have one problem: my tableView doesn't show any data from realm database. But i guess the problem is in cell.

class ClientViewController: UITableViewController {

    @IBOutlet var table: UITableView!
    var clientsInfo: Results<Client> {
        get {
            return realm.objects(Client.self)
        }
    }

    override func viewDidLoad() {
        super.viewDidLoad()
        self.tableView.register(myCell.self, forCellReuseIdentifier: "cell")
        table.delegate = self
        table.dataSource = self
        table.reloadData()
    }
    override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
        let cell = tableView.dequeueReusableCell(withIdentifier: myCell.reuseIdentifier, for: indexPath) as! myCell
        let info=clientsInfo[indexPath.row]
        cell.todoLabel.text = info.firstName
        return cell

    }
}

class myCell: UITableViewCell {
    @IBOutlet weak var label: UILabel!

    static let reuseIdentifier = "cell"


    @IBOutlet weak var todoLabel: UILabel!

    override init(style: UITableViewCellStyle, reuseIdentifier: String?) {
        super.init(style: style, reuseIdentifier: reuseIdentifier)

    }
}

There is a few things wrong in your code,

First:

You're using a UITableViewController, by default this already has a tableView, so you don't need to declare a new tableView like you did

@IBOutlet var table: UITableView!

Second:

In you viewDidLoad you're registering the cell for the default tableView and using your declared table for dataSource and delegate, this won't work. I recommend you remove the table you create and use the default so your viewDidLoad would look like this:

override func viewDidLoad() {
        super.viewDidLoad()
        self.tableView.register(myCell.self, forCellReuseIdentifier: "cell")
        self.tableView.delegate = self
        self.tableView.dataSource = self
    }

and Third:

you're missing the implementation of :

func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int

In this code you forgot to implement tableView(numberOfRowsInSection:) method, so it returns 0 by default and your tableview(cellForRowAt:) method never called.

AND

Maybe this is not about your question but;

You used UITableView variable(name is table) in UITableView. It's unneccessary, because UITableView already has a UITableView(name is tableView). And you'have registered your cell into tableView, but it seems you try to dequeue this cell from table.
