如何在Coredata中存储带有struct的自定义对象

import CoreData

class CustomObject: NSManagedObject {
    @NSManaged var structData: NSData // 非持久化属性，用于存储struct对象
    
    var customStruct: CustomStruct {
        get {
            // 从NSData中解析struct对象
            let data = structData as Data
            let customStruct = try! NSKeyedUnarchiver.unarchivedObject(ofClass: CustomStruct.self, from: data)
            return customStruct!
        }
        set {
            // 将struct对象转换为NSData
            let data = try! NSKeyedArchiver.archivedData(withRootObject: newValue, requiringSecureCoding: false)
            structData = data as NSData
        }
    }
}

struct CustomStruct: Codable {
    var property1: String
    var property2: Int
}

// 使用自定义对象
let context = persistentContainer.viewContext
let customObject = CustomObject(context: context)
customObject.customStruct = CustomStruct(property1: "Value1", property2: 2)

// 存储自定义对象
try! context.save()

// 查询自定义对象
let fetchRequest: NSFetchRequest<CustomObject> = CustomObject.fetchRequest()
let results = try! context.fetch(fetchRequest)
for customObject in results {
    let customStruct = customObject.customStruct
    print(customStruct.property1)
    print(customStruct.property2)
}
