swift - [元素]' requires that '元素'继承自 'Object'

Question

我要转换Array<User>至List<User>使用此扩展

extension Array where Element: Object {
    var asRealMList: List<Element>{
        let list = List<Element>()
        list.append(objectsIn: self)
        return list
    }
}

和这个用户类

class User: Object, Codable {
    convenience init(username: String) {
        self.init()
        self.username = username
    }

    @objc dynamic var username: String = ""
    @objc dynamic var displayName, displayNameAr, email, phoneNumber: String?
    @objc dynamic var department, userProfilePicture, samAccountName: String?
    let isActiveDirectoryUser = RealmOptional<Bool>()

    enum CodingKeys: String, CodingKey {
        case username = "Username"
        case displayName = "DisplayName"
        case email = "Email"
        case phoneNumber = "PhoneNumber"
        case department = "Department"
        case userProfilePicture = "ExternalUserProfilePicture"
        case samAccountName = "SamAccountName"
        case isActiveDirectoryUser
        case displayNameAr = "DisplayNameAR"
    }
}

但由于某种原因它显示编译错误

'[User]' requires that 'User' inherit from 'Object'

我无法理解为什么，希望这里有人可以为我们其他人澄清这一点我在 init 中传递列表，如下所示

Task(users: users.asRealmList,...)

但是当我将它移出 init 时，如下所示

let usersList = users.asRealmList
Task(users: usersList,...)

效果很好!此更改如何解决问题？
