我的TableView只列出了itemArray中的最后一项？

我的 itemArray 中有四个项目，但我的 TableView 只列出了我最后一个附加的项目，它首先列出了它。但是，我可以选中和取消选中实际包含文本的第一行下方的三行。

    import UIKit

class ToDoListViewController: UITableViewController {

    var itemArray = [Item]()
    
    let defaults = UserDefaults.standard
    
    override func viewDidLoad() {
        super.viewDidLoad()
        
        let newItem = Item()
        newItem.title = "Find Mike"
        itemArray.append(newItem)
        
        let newItem2 = Item()
        newItem.title = "Buy Eggos"
        itemArray.append(newItem2)

        let newItem3 = Item()
        newItem.title = "Destroy Demongorgon"
        itemArray.append(newItem3)
        
        let newItem4 = Item()
        newItem.title = "RockOn!"
        itemArray.append(newItem4)
        
        
//        if let items = defaults.array(forKey: "ToDoListArray") as? [String] {
//            itemArray = items
//      }
    }

//MARK: - TableView Datasource Methods
    
    override func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
        return itemArray.count
    }
    
    override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
        
        let cell = tableView.dequeueReusableCell(withIdentifier: "ToDoItemCell", for: indexPath)
        
        let item = itemArray[indexPath.row]
        
        cell.textLabel?.text = item.title
        
        cell.accessoryType = item.done ? .checkmark : .none
        
        return cell
    }
    
//MARK: - TableView Delegate Methods
    
    override func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
        //print(itemArray[indexPath.row])
        
        itemArray[indexPath.row].done = !itemArray[indexPath.row].done
        
        tableView.reloadData()
        
         tableView.deselectRow(at: indexPath, animated: true)
    }
    //MARK: - Add New Items
    
    @IBAction func addButtonPressed(_ sender: UIBarButtonItem) {
        
        var textField = UITextField()
    
        let alert = UIAlertController(title: "Add New Todoey Item", message: "", preferredStyle: .alert)
        
        let action = UIAlertAction(title: "Add Item", style: .default) { (action) in
            //what will happen once the user clicks the add item
            
            let newItem = Item()
            newItem.title = textField.text!
            
            self.itemArray.append(newItem)
            
            self.defaults.set(self.itemArray, forKey: "ToDoListArray")
            
            self.tableView.reloadData()
        }
        
        alert.addTextField { (alertTextField) in
            alertTextField.placeholder = "Create new item"
            textField = alertTextField
        }
        
        alert.addAction(action)
        
        present(alert, animated: true, completion: nil)
    
    }    
}

StackOverflow 说我需要更多描述……我认为这说明了一切……这是针对 Udemy iOS 系列的……
