Question

当我的程序注册用户时，它使用以下方法验证用户名和密码：

func authenticate(username: String, password: String, register: Bool, callback: @escaping (NSError?) -> Void) {

    let credentials = SyncCredentials.usernamePassword(username: username, password: password, register: register)

    SyncUser.logIn(with: credentials, server: Constants.syncAuthURL) { user, error in

        DispatchQueue.main.async {

            if let user = user {
                setDefaultRealmConfiguration(with: user)
            }

            // handle error

        }
    }
}

setDefaultRealmConfiguration(with: user)如下所示：

public func setDefaultRealmConfiguration(with user: SyncUser) {

    print("DEFAULT REALM CONFIG SET")

    Realm.Configuration.defaultConfiguration = Realm.Configuration(
        syncConfiguration: SyncConfiguration(user: user, realmURL: Constants.syncServerURL!),
        objectTypes: [UserData.self, Achievement.self])
}

我是否认为这足以让我在验证用户身份后创建领域let realm = try! Realm()并从中进行写入/读取？因为在写入领域后，注销用户SyncUser.current.logOut()，然后使用authenticate重新登录，所有书面信息似乎都丢失了。信息不多，只是几个字符串（尽管如此，我实现了一个计时器，看看是否有效 - 但事实并非如此）。

以下是日志：

REALM IS EMPTY

Answer 1

事实证明，在进行默认领域配置之前，我正在初始化Realm的一个实例......这意味着我正在调查另一个（离线）领域而不是我写作的那个领域。在authentication函数中重新声明领域实例可以解决问题。

无法在同步后加载领域对象：尽管编写了
