`Error decoding item array: The data couldn’t be read because it is missing.`

, and on the Simulator , there is no icon appeared. Could anyone give me a hint ?

AllListsViewController.swift#######

override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell { //let cell = makeCell(for: tableView) let cell: UITableViewCell!

    if let c = tableView.dequeueReusableCell(withIdentifier: cellIdentifier) {
        cell = c
    }else {
        cell = UITableViewCell(style: .subtitle, reuseIdentifier: cellIdentifier)
    }
    // Update cell information
    let checklist = dataModel.lists[indexPath.row]
    cell.textLabel!.text = checklist.name
    cell.accessoryType = .detailDisclosureButton
    
    // Access subtitle of label
    cell.detailTextLabel!.text = "\(checklist.countUncheckedItems()) Remaining"
    
    let count = checklist.countUncheckedItems()
    if checklist.items.count == 0 {
        cell.detailTextLabel!.text = "(No items)"
    }else {
        cell.detailTextLabel!.text = count == 0 ? "All done!" : "\(count) Remaining"
    }
    
    cell.imageView!.image = UIImage(named: checklist.iconName)
    return cell
}`
