json - 为什么 tableview 没有在 swift 中重新加载 JSON 数据

Question

我的屏幕看起来像这样

在此处输入图像描述

在这里，如果我添加所有字段并单击提交按钮，那么我需要在 tableview 中显示该数据.. 这即将到来但如果我停止构建并再次运行，则 tableview JSON 数据没有显示，为什么？

代码：

 class WithdrawFundsVC: UIViewController, UITableViewDelegate, UITableViewDataSource 
 {

 private var withdrawData = WithdrawModel(dictionary: NSDictionary()){
    didSet  {
        tableView.reloadData()
    }
    }

   override func viewWillAppear(_ animated: Bool) {
    withdrawServicecall()
    tableView.reloadData()
   }

 func withdrawServicecall(){
    
 if bankmode == "B"
 {
  parameters = ["payment_method" : "B", "bank_name" : nankNameTextfield.text, "bank_account_no" : accNumTextField.text, "bank_account_holder_name" : accNameTextfield.text, "bank_code" : bankCOdeTextField.text, "bank_amount" : amountTextField.text] as [String : Any]
 }

 if bankmode == "P"{
  parameters = ["payment_method" : "P", "paypal_email" : paypalEmail.text, "paypal_amount" : paypalAmount.text] as [String : Any]
  }

    APIReqeustManager.sharedInstance.serviceCall(param: parameters as [String : Any], method: .post, loaderNeed: false, loadingButton: nil, needViewHideShowAfterLoading: nil, vc: self, url: CommonUrl.withdrawal_money, isTokenNeeded: true, isErrorAlertNeeded: true, isSuccessAlertNeeded: true, actionErrorOrSuccess: nil, fromLoginPageCallBack: nil) { [weak self] (resp) in

    if let code = ((resp.dict?["result"] as? [String : Any])){
        let success = code["status"] as? [String : Any]
        let message = success?["message"] as? String
        if message == "Success"{
           print("result of withdrawal \(code)")
        }
    }else{
        self?.view.makeToast(CommonMessages.somethingWentWrong)
    }
    self?.withdrawData = WithdrawModel(dictionary: resp.responseDict as? NSDictionary ?? NSDictionary())
}
    
}

@IBAction func submitBtnaction(_ sender: Any) {
    withdrawServicecall()
}

func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return withdrawData?.result?.withdrawal_list?.count ?? 0
}

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {

let cell = tableView.dequeueReusableCell(withIdentifier: "WithdrawfundTableViewCell", for: indexPath) as! WithdrawfundTableViewCell
let indexData = withdrawData?.result?.withdrawal_list?[indexPath.row]
cell.transferModelabel.text = "\(indexData?.payment_method ?? "") Transfer"
return cell

 }

将此代码数据成功添加到 tableview.. 但如果我停止并再次运行.. tableview 没有显示。为什么？

请指导我
