NSDebugDescription =存档期间捕获到异常：-[TCHMembers encodeWithCoder：]：无法识别的选择器已发送到实例

Question

我正在尝试将API中的数据存储在我的NSObject类中，然后将其保存到核心数据中。响应具有一个数据类型为TCHMembers的变量，该变量为twilio类，此TCHMembers是一个NSObject类，它具有一些必须在进一步的代码中调用的方法。现在，当我尝试通过NSKeyedArchive将其存储在核心数据实体中时，该应用程序将捕获bllock并通过错误NSDebugDescription=Caught exception during archival: -[TCHMembers encodeWithCoder:]: unrecognized selector sent to instance。我如何将其存储在核心数据中，我认为数据类型给出此错误，如何存储该错误？

 let createdBy = items.twChannelObj?.createdBy
