I am creating an app with a UITableViewController but I am getting the error:

'unable to dequeue a cell with identifier cell - must register a nib or a class for the identifier or connect a prototype cell in a storyboard'

I don't understand how I to find the solution and fix it.

Please show us the relevant code, especially how you're registering your cell class and your tableView:cellForRowAt: method. – Smartcat
The identifier you are using in cellForRowAtIndexPath must be provided in the storyboard by selecting that particular cell – shivi_shub
override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell { let cell = tableView.dequeueReusableCell(withIdentifier: "cell", for: indexPath) as! YemekTarifi_TVCell cell.yemekadi.text! = "köfte" return cell } – dogabalkis

You need to register the table with a cell before dequeue in viewDidLoad with xib 

tableView.register(UINib(nibName: "TableCell", bundle: nil), forCellReuseIdentifier: "cell")

OR

tableView.register(TableCell.self, forCellReuseIdentifier: "cell")

It's clear here from the crash

unable to dequeue a cell with identifier cell - must register a nib or a class for the identifier or connect a prototype cell in a storyboard'

As @Sh_Khan pointed out. You can register the cell in code or you can also register the reuse identifier in Storyboard, if you are using prototype cells.
