如何访问与Uisearchbar一起使用的结构枚举值？

Question

我正在努力学习创建和使用UITAITEVIEW和UISEARCHBAR的更复杂的结构。我有一个表，在2个部分中显示以下结构。

struct ReceiveInResponse: Codable {

    var result: [ReceiveIn]

}

struct ReceiveIn: Codable {

    var section: String
    var items: [ReceiveInComp]

    enum CodingKeys: String, CodingKey {
        case section = "Section"
        case items
    }

}

struct ReceiveInComp: Codable {

   let owner, barcode, quantity: String
   let resultDescription, status: String

   enum CodingKeys: String, CodingKey {
      case owner = "Owner"
      case barcode = "Barcode"
      case quantity = "Quantity"
      case resultDescription = "Description"
      case status = "Status"
   }

}

我已经多次实施了搜索栏。但是这一次，我在尝试搜索案例条形码的值时会遇到错误。这是错误。

Type '[ReceiveInComp]' has no member 'barcode'

这是我的代码

func searchBar(_ searchBar: UISearchBar, textDidChange searchText: String) {
    
    self.filteredList = []

    if (searchText == "") {
        self.filteredList = self.ReviewList
    } else {
        for comp in self.ReviewList {
            
            let myitems = comp.items

尝试1

            switch myitems {

                case .barcode(let barcode): do { // error thrown here
                    if (barcode.lowercased().contains(searchText.lowercased())) {
                        self.filteredList.append(comp)
                    }
                }
            }

尝试2
var barcode = myitems.barcode //在此处丢弃的错误，

            if (barcode.lowercased().contains(searchText.lowercased())) {
                self.filteredList.append(comp)
            }
        }
    }
    self.tableView.reloadData()
}

我可以打印Myitems以控制并查看其包含的值。如何访问条形码的值以与搜索文本进行比较？

中打印（myitems）时看到的样本，

App.ReceiveInComp(owner: "E3D Rental", barcode: "10021640", quantity: "1", resultDescription: "2X2. X42 BLK CABINET ", status: "missing"),

这是我在控制台解决方案

        for comp in self.ReviewList {
            
            let myitems = comp.items
            
            for item in myitems{
                
                let barcode = item.barcode
                if (barcode.lowercased().contains(searchText.lowercased())) {
                    self.filteredList.append(comp)
                }
                
                
            }
}

这似乎有效，出于某种原因而在搜索结果中获得重复，但先前的错误已经消失。谢谢@shadowrun
