func tableView（_ tableView：UITableView，didSelectRowAt indexPath：IndexPath）{
self.selectedIndexPath = indexPath as NSIndexPath
performSegue(withIdentifier: "toAddToChart", sender: nil)
}
open override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
let indexPath = self.selectedIndexPath
let product = products[indexPath.row]
if (segue.identifier == "toAddToChart") {
if let viewController = segue.destination as? AddToOrderVC {
viewController.productName = product.productName
viewController.productCode = product.productCode
viewController.productType = product.productType
viewController.productPrice = product.productPrice
viewController.productDetails = product.productDescription
viewController.pImageUrl = product.productimageUrl
}
}
}
/当我从viweController中删除prepareForSegue函数时它会起作用但是当我应用它并且在构建代码之后我得到线程1：当按下另一个动作segue按钮时发出信号SigBArt错误

如果让product = products [indexPath.row]在确认标识符的segue旁边调用，则会出现错误，因此出现此错误
