我正在尝试将RealmObjects写入数据库，当我尝试插入它时，我收到此属性incompatible type错误。问题是它说它不能持久保存属性timestampe，即使我的RealmObject中不存在这个属性。这是领域中的领域对象：
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"]
}
}
正如您所看到的，没有任何外来类型，也没有timestamp属性。有什么想法吗？

我的整个项目中没有timestamp属性，所以我不确定它来自哪里。这是插入领域db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db做任何异国情调。
