I have the following code in a viewController:

Code Block extension InvoicesDetailController: NSTableViewDelegate {
    fileprivate enum CellIdentifiers {
        static let lineItemLabelCell = "lineItemLabelCell"
        static let lineItemDescCell = "lineItemDescCell"
        static let lineItemAmountCell = "lineItemAmountCell"
        static let lineItemQtyCell = "lineItemQtyCell"
    }
    fileprivate enum fieldIdentifiers {
        static let lineItemLabel = "lineItemLabel"
        static let lineItemDesc = "lineItemDesc"
        static let lineItemAmount = "lineItemAmount"
        static let lineItemQty = "lineItemQty"
    }
  func tableView(_ tableView: NSTableView, viewFor tableColumn: NSTableColumn?, row: Int) -> NSView? {
        let currentItem = invoiceItems[row]
        var text: String = ""
        var cellIdentifier: String = ""
        let currentColumn = tableColumn?.identifier.rawValue
        if currentColumn == fieldIdentifiers.lineItemLabel {
            text = currentItem.lineItemLabel!
            cellIdentifier = CellIdentifiers.lineItemLabelCell
        }
        if currentColumn == fieldIdentifiers.lineItemDesc {
            text = currentItem.lineItemDesc!
            cellIdentifier = CellIdentifiers.lineItemDescCell
        }
        if currentColumn == fieldIdentifiers.lineItemAmount {
            text = currentItem.lineItemDesc!
            cellIdentifier = CellIdentifiers.lineItemAmountCell
        }
        if currentColumn == fieldIdentifiers.lineItemQty {
            text = currentItem.lineItemQty!
            cellIdentifier = CellIdentifiers.lineItemQtyCell
        }
        if let cell = tableView.makeView(withIdentifier: NSUserInterfaceItemIdentifier(rawValue: cellIdentifier), owner: self) as? NSTableCellView {
            print(cell.textField?.stringValue)
            cell.textField?.stringValue = text
            print(text, cell.textField?.stringValue)
            return cell
        }
        return nil
    }

I have used this code (similar code in other places and it works fine, however in this case the tableView Cells are not being populated. When I look at this code using debugger the line

Code Block  if let cell = tableView.makeView(withIdentifier: NSUserInterfaceItemIdentifier(rawValue: cellIdentifier), owner: self) as? NSTableCellView

always sets cell to nil? Since I don't see anything wrong with code I suspect there is an issue with the IB?

Any ideas how to fix or how to debug further?

I found the problem, It was in the IB... there was not a connection from the column textField to the table view cell.
