Custom table cell class not working in cellForRowAt

Question

This issue is driving me crazy for 3 days. I created a custom cell class:

class TransitoPalinaTableViewCell: UITableViewCell {

@IBOutlet weak var lblOrario: UILabel!
@IBOutlet weak var lblDestinazione: UILabel!
@IBOutlet weak var lblNote: UILabel!
@IBOutlet weak var lblBus: UILabel!

override func awakeFromNib() {
    super.awakeFromNib()
    // Initialization code
}

override func setSelected(_ selected: Bool, animated: Bool) {
    super.setSelected(selected, animated: animated)

    // Configure the view for the selected state
}

}

and in my view controller I have this:

override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {

    let cell = tableView.dequeueReusableCell(withIdentifier: "Cell", for: indexPath) as! TransitoPalinaTableViewCell

    // Configure the cell...
    let hour = Int(self.transito.listaCorse[indexPath.row].tempoTransito) / 3600
    let mins = Int(self.transito.listaCorse[indexPath.row].tempoTransito % 3600) / 60

    cell.lblOrario?.text = String(format: "%02d:%02d", hour, mins)
    cell.lblDestinazione?.text = self.transito.listaCorse[indexPath.row].arrivoCorsa
    cell.lblNote?.text = ""
    cell.lblBus?.text = self.transito.listaCorse[indexPath.row].automezzo


    cell.backgroundColor = UIColor.init(red: 0, green: 60/255, blue: 113/255, alpha: 1)

    return cell
}

In the storyboard I set the table view cell Identifier: "Cell" and Custom Class "TransitoPalinaTableViewCell".

The problem is that when cellForRowAt is called I got the error

Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: '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'

at the line of dequeueReusableCell command.

As I read in other posts I didn't put the line self.tableView.register(TransitoPalinaTableViewCell.self, forCellReuseIdentifier: "Cell") in the viewdidLoad() - it'd create a brand new cell model, not connected with the outlets in the storyboard. I tried to create again the TransitoPalinaTableViewCell class and its outlets but nothing changed.

Any help appreciated.

You can register a cell with either cell class or cell nib.

tableView.register(UINib(name: "YourNibName", bundle: nil), forCellReuseIdentifier: "Cell")

but that works only if you created a cell in Xib file. If it's created in Storyboard, then I'm afraid it's not possible to use that cell anywhere else than the ViewController you created it in.
