如何修复“此编码器只对采用NSSecureCoding的对象进行编码(对象属于‘_SwiftValue’类)。”来自Crashlytics的崩溃

在上次更新我们的应用后，我遇到了在exeption上崩溃的问题：
-[NSXPCEncoder _checkObject:]: This coder only encodes objects that adopt NSSecureCoding (object is of class '_SwiftValue').我试着删除我在这个更新中添加的库，但是没有帮助。奇怪的是，它只在iOS 12上崩溃。我们从iOS 9开始支持。我不能重现崩溃。

在遇到同样的问题后，我发现原因是当你试图将一些东西放在userInfo中时，它必须符合NSSecureCoding。这是在错误消息中声明的，但其含义是：
此字典中的键必须是属性列表类型-也就是说，它们必须是可以序列化为属性列表格式的类型。
话虽如此，但值得一提的是这些类型：
数组，字典，字符串，数据，日期，数字(整数/浮点数)，布尔值
我自己找到的解决方案是将一个对象存储为Data，然后传递到userInfo中。
