您好我在运行表视图控制器时遇到以下错误。 我试图在UITableViewController中显示一些带编码的文本。

我正在尝试运行简单的TableView控制器
表视图控制器的代码如下：
import Foundation
import UIKit
class FeedsTableViewController: UITableViewController, UserView {
private var userPresenter: UserPresenter?
override func viewDidLoad() {
super.viewDidLoad()
userPresenter = UserPresenter(userView: self)
//userPresenter?.getUsers()
}
func startLoading() {
print("Loading started")
}
func stopLoading() {
print("Stop loading")
}
func onEmpty() {
print("No users available")
}
func onUsers(users: [User]) {
print("Users \(users.count)")
}
override func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
print("number of section row fine")
return 10
}
override func numberOfSections(in tableView: UITableView) -> Int {
return 1
}
override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
print("number Getting item")
let cellItem = tableView.dequeueReusableCell(withIdentifier: "USER_ITEM_ROW", for: indexPath)
//cellItem.textLabel?.text = "sdadas"
return cellItem
}
}
