Xcode can't find my cell identifier - ios

Question

I'm getting an error with my code that says...
"Terminating app due to uncaught exception
'NSInternalInconsistencyException', reason: 'unable to dequeue a cell
with identifier ItemCell - must register a nib or a class for the
identifier or connect a prototype cell in a storyboard'?"
I've set the cell to ItemCell and I've run Product > Clean. It still can't find it. Can anyone see what I've done wrong? I've included a screen shot of my code and my storyboard.
import UIKit
class ItemsViewController: UITableViewController {
var itemStore: ItemStore!
#IBAction func addNewItem(_ sender: UIButton) {
let newItem = itemStore.createItem()
if let index = itemStore.allItems.index(of: newItem) {
let indexPath = IndexPath(row: index, section: 0)
tableView.insertRows(at: [indexPath], with: .automatic)
}
}
#IBAction func toggleEditingMode(_ sender: UIButton) {
if isEditing {
sender.setTitle("Edit", for: .normal)
setEditing(false, animated: true)
} else {
sender.setTitle("Done", for: .normal)
setEditing(true, animated: true)
}
}
override func viewDidLoad() {
super.viewDidLoad()
let statusBarHeight = UIApplication.shared.statusBarFrame.height
let insets = UIEdgeInsetsMake(statusBarHeight, 0, 0, 0)
tableView.contentInset = insets
tableView.scrollIndicatorInsets = insets
tableView.rowHeight = 65
}
override func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return itemStore.allItems.count
}
override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "ItemCell", for: indexPath) as! ItemCell
let item = itemStore.allItems[indexPath.row]
cell.nameLabel.text = item.name
cell.serialNumberLabel.text = item.serialNumber
cell.valueLabel.text = "$\(item.valueInDollars)"
return cell
}
override func tableView(_ tableView: UITableView,
commit editingStyle: UITableViewCellEditingStyle,
forRowAt indexPath: IndexPath) {
if editingStyle == .delete {
let item = itemStore.allItems[indexPath.row]
let title = "Delete \(item.name)"
let message = "You sure ya wanna delete this?"
let ac = UIAlertController(title: title,
message: message,
preferredStyle: .actionSheet)
let cancelAction = UIAlertAction(title: "Cancel", style: .cancel, handler: nil)
ac.addAction(cancelAction)
let deleteAction = UIAlertAction(title: "Delete", style: .destructive, handler: { (action) -> Void in
self.itemStore.removeItem(item)
self.tableView.deleteRows(at: [indexPath], with: .automatic)
})
ac.addAction(deleteAction)
present(ac, animated: true, completion: nil)
}
}
override func tableView(_ tableView: UITableView,
moveRowAt sourceIndexPath: IndexPath,
to destinationIndexPath: IndexPath) {
itemStore.moveItem(from: sourceIndexPath.row, to: destinationIndexPath.row)
}
This is my ItemCell
import UIKit
class ItemCell: UITableViewCell {
#IBOutlet var nameLabel: UILabel!
#IBOutlet var serialNumberLabel: UILabel!
#IBOutlet var valueLabel: UILabel!
}
And my ItemStore
import UIKit
class ItemStore {
var allItems = [Item] ()
#discardableResult func createItem() -> Item {
let newItem = Item(random: true)
allItems.append(newItem)
return newItem
}
func removeItem(_ item: Item) {
if let index = allItems.index(of: item) {
allItems.remove(at: index)
}
}
func moveItem(from fromIndex: Int, to toIndex: Int) {
if fromIndex == toIndex {
return
}
let movedItem = allItems[fromIndex]
allItems.remove(at: fromIndex)
allItems.insert(movedItem, at: toIndex)
}
}

Answer 1

You have to check your custom class name in storyboard as ItemCell.swift as your class name.
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
// create a new cell if needed or reuse an old one
let cell:ItemCell = tableView.dequeueReusableCell(withIdentifier: "ItemCell") as! ItemCell
let item = itemStore.allItems[indexPath.row]
cell.nameLabel.text = item.name
cell.serialNumberLabel.text = item.serialNumber
cell.valueLabel.text = "$\(item.valueInDollars)"
return cell
}

Answer 2

Check if you have set the correct custom class for the cell (ItemCell in this case) in Identity Inspector.
