swift - Realm swift中神秘的“时间戳”属性

Question

我正在尝试将 RealmObjects 写入数据库，incompatible type当我尝试插入它时出现此属性错误。问题是它说timestampe即使我的 RealmObject 中不存在此属性，它也无法保留该属性。这是领域对象的逐字记录：

class TransferR: Object {
    @objc dynamic var from_stop_id: String = ""
    @objc dynamic var to_stop_id: String = ""
    @objc dynamic var transfer_type: String = ""
    @objc dynamic var min_transfer_time: String = ""
    @objc dynamic var transfer_id:String = ""
    required convenience init(from_stop_id: String = "", to_stop_id: String = "", transfer_type: String = "", min_transfer_time: String = "") {
        self.init()
        self.from_stop_id = from_stop_id
        self.to_stop_id = to_stop_id
        self.transfer_type = transfer_type
        self.min_transfer_time = min_transfer_time
        self.transfer_id = transfer_type + "_" + from_stop_id + "_" + to_stop_id
    }

    override static func primaryKey() -> String? {
        return "transfer_id"
    }

    override static func indexedProperties() -> [String] {
        return ["from_stop_id", "to_stop_id"]
    }
}

如您所见，没有任何外来类型，也没有timestamp属性。有任何想法吗？

我的整个项目中没有timestamp财产，所以我不确定它是从哪里来的。这是插入领域数据库的代码：

while csv.next() != nil {
                let row = rp.process(csv: csv)
                realmObjects.append(row)
                if (realmObjects.count > 10000) {
                    try realm.write {
                        realm.add(row)
                    }
                    DDLogInfo("Committing /(realmObjects.count) to the \(table) table.")
                    realmObjects = Array<Object>()
                }
            }

我没有对数据库做任何异国情调的事情。
