Xib file UITableViewCell outlets are nil - ios

Question

This is a bit of an ongoing topic, but my situation is slightly different. I'm working with this tutorial. I have a view controller, that has it's own storyboard, this view controller has table view. The view controller is this table's delegate and data source. I need to add different kinds of cells to this table, and I'm using cell view model as well for this.
Cell:
class TitleTextCell: UITableViewCell, CellConfigurable {
#IBOutlet weak var titleLabel: UILabel!
#IBOutlet weak var textView: UITextView!
static let identifier = "TitleTextCell"
func setup(viewModel: RowViewModel) {
guard let titleTextViewModel = viewModel as? TitleTextViewModel else {return}
titleLabel.text = titleTextViewModel.title //fatal: found nil while
textView.text = titleTextViewModel.text //unwrapping an optional value
}
}
Table view controller's ViewController:
class InfoViewController: UIViewController, Storyboarded {
// MARK: - Properties
var viewModel: InfoViewModelType! {
didSet {
viewModel.viewDelegate = self
}
}
// MARK: - Outlets
#IBOutlet weak var tableView: UITableView!
// MARK: - Lifecycle Methods
override func viewDidLoad() {
super.viewDidLoad()
tableView.register(TitleTextCell.self, forCellReuseIdentifier: TitleTextCell.identifier)
tableView.delegate = self
tableView.dataSource = self
}
}
extension InfoViewController: UITableViewDelegate, UITableViewDataSource {
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return viewModel.tableRows.count
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let rowViewModel = viewModel.tableRows[indexPath.row]
let cell = tableView.dequeueReusableCell(withIdentifier: cellIdentifier(for: rowViewModel), for: indexPath)
if let cell = cell as? CellConfigurable {
cell.setup(viewModel: rowViewModel)
}
return cell
}
private func cellIdentifier(for viewModel: RowViewModel) -> String {
switch viewModel {
case is TitleTextViewModel:
return TitleTextCell.identifier
default:
fatalError("Unexpected view model type: \(viewModel)")
}
}
}
The cell is a xib file. Outlets are connected with the file owner (see screens).
It does arrive at the point of func setup(viewModel: RowViewModel) which means table-wise it's correct. But the outlets are nil at runtime, what am I missing?

Answer 1

You need
tableView.register(UINib(nibName: "TitleTextCell", bundle: nil), forCellReuseIdentifier: TitleTextCell.identifier)
For xib cells
