错误：当我尝试单击TableView单元格时，无法识别的选择器发送到实例

如何解决错误：当我尝试单击TableView单元格时，无法识别的选择器发送到实例

编辑

我只能在模拟器中单击表格视图的一个单元格。如果我单击一个单元格（不管是哪个单元格），然后单击任何其他单元格，应用程序就会崩溃。

这是我单击表视图的第二个单元格时遇到的错误：

线程1：异常：“-[Goals_V2.FieldTableViewCell字段：]：无法识别的选择器已发送到实例0x7f95b68100c0”

这是代码：

FieldTableViewCell.swift

class FieldTableViewCell: UITableViewCell,UITextFieldDelegate {
    
    static let identifier = "FieldTableViewCell"
    
    static func nib() -> UINib {
        return UINib(nibName: "FieldTableViewCell",bundle: nil)
    }
    
    @IBOutlet var field: UITextField!
    
    
    override func awakeFromNib() {
        super.awakeFromNib()
        field.placeholder = ("What would you like to do today")
        field.delegate = self
        
    }
    
    func textFieldShouldReturn(_ textField: UITextField) -> Bool {
        print("\(textField.text ?? "")")
        return true
    }
    override func setSelected(_ selected: Bool,animated: Bool) {
        super.setSelected(selected,animated: animated)
        var allowsSelection: Bool { true }
    }
}

FirstViewController.swift

class FirstViewController: UIViewController,UITableViewDelegate,UITableViewDataSource {
    
    
    
    @IBOutlet var table: UITableView!

    override func viewDidLoad() {
        super.viewDidLoad()
        table.register(FieldTableViewCell.nib(),forCellReuseIdentifier: FieldTableViewCell.identifier)
        table.delegate = self
        table.dataSource = self
        
    }

    
    func tableView(_ tableView: UITableView,numberOfRowsInSection section: Int) -> Int {
        return 5
    }
    
    func tableView(_ tableView: UITableView,cellForRowAt indexPath: IndexPath) -> UITableViewCell {
        let cell = tableView.dequeueReusableCell(withIdentifier: FieldTableViewCell.identifier,for: indexPath) as! FieldTableViewCell
        
        return cell
    }

}

表格视图的屏幕截图

如果我单击一个单元格，则可以正常运行，但是如果此后单击另一个单元格，则应用程序将崩溃

线程1的完整堆栈跟踪

以蓝色突出显示的位置是异常断点捕获异常的地方。 我必须为完整堆栈跟踪拍摄两个屏幕截图，因为它无法显示在屏幕上，但是图像从上到下都是链接
