Ios 如何使用域存储字符串枚举

我无法将数据保存为域中的枚举。当我跟踪变量的状态并保存时，旧值将保留，而不是新值。我做错了什么

我用了一个二传手和一个接球手，但问题仍然没有解决

import RealmSwift

class Transaction: Object {

var accounting: Accounting = .income
@objc dynamic var amount = 0
@objc dynamic var date = ""
@objc dynamic var note = ""

private var privateCategory: String = Category.noCategories.rawValue
var category: Category {
    get { return Category(rawValue: privateCategory)! }
    set { privateCategory = newValue.rawValue }
  } 
}

enum Category: String {
   case noCategories = "No сategories"
   case food = "Food"
   case cafesAndRestaurants = "Cafes And Restaurants"
   case manufacturedGoods = "Manufactured Goods"
   case forceMajeure = "Force Majeure"
   case entertainment = "Entertainment"
}

当我试图保存属性时，С类别由defaultNo类别保存

let transactionOne = Transaction()
    transactionOne.accounting = .consuption
    transactionOne.amount = 250
    transactionOne.category = .food

事务私有类别字符串无类别

从中的所有示例可以看出，要持久化的字符串属性都标记为@objc dynamic。因此，您也应该将PrivateCegory标记为@objc dynamic：

您忘记将其标记为@objc dynamic。它不工作=/即使使用@objc dynamic？请尝试删除私有修饰符。属性无法标记为@objc，因为它的类型无法在Objective CDelete中表示。请先在模拟器上删除应用程序，然后再次运行它。另见：

@objc dynamic var privateCategory: String = Category.noCategories.rawValue
