ios - 核心数据 : Can't find model for source store - only in simulator?

Question

当我的应用程序启动并且我的堆栈已初始化时，我收到错误:

Can't find model for source store

但是，只有当我在模拟器中运行该应用程序时才会发生这种情况。它在我的设备上运行良好。我以前遇到过这个错误(同样，只在模拟器上)，我做了一个轻量级的迁移，但现在又回来了。有人可以解释为什么它在模拟器上崩溃但在我的设备上运行吗？

这是扩展的崩溃日志(我有一个名为 Date 的实体):

}, reason=Can't find model for source store})

尝试重置并清除模拟器的数据。我在执行迁移时遇到过类似的问题。这总能帮我解决问题。
