core-data - Core Data 自动轻量级迁移失败

Question

每次 Core Data 在我的应用程序（当前使用“Model 2.5”）中创建新版本的模型（我们称之为“Model 2.6”）后尝试进行自动轻量级迁移时，我都会崩溃。

我已经使用 Core Data 有一段时间了，我很清楚，每当我需要为新版本更改模型时，我必须使用“编辑器 --> 添加模型版本”，给那个版本一个新的标识符，并使用“当前版本”弹出窗口切换到该标识符。我熟悉“用于打开商店的模型与用于创建商店的模型不兼容”错误，因为我以前犯过这个错误。我相信我遇到了不同的问题，尽管收到了相同的错误消息。

在周末的大部分时间里我都反对这个之后，我希望有人以前见过这个并且可以提供一些明智的建议。

这是我触发问题的步骤：

重置模拟器，核对派生数据，清理构建并以 2.5 格式保存文件。
在 Xcode 中，编辑器 --> 添加模型版本...
使用该向导基于“Model 2.5”制作“Model 2.6”
将新人的标识符更改为“2.6”
对与自动轻量级迁移完全兼容的新版本做一些超级简单的事情，比如添加一个新实体。
在当前版本的弹出窗口下设置“模型 2.6”
在模拟器中重建和启动。打开我刚刚保存的 2.5 文件时崩溃。

到目前为止，我已经成功地管理了九个不同版本的文件格式更新，并且自动轻量级迁移始终完美无缺。

现在和上次的区别：

我的模型版本 2.5 是我第一次将“工具版本”设置为“自动（Xcode 8）”。所有以前的版本都将此设置为“Xcode 7.3”，因此这将是第一次从已经在“自动（Xcode 8）”上的模型版本进行迁移
我的 xcdatamodeld（因此也是 momd 文件）现在存在于我的共享框架中，而不是主机应用程序中（因此我可以在扩展程序、tvOS 等之间共享代码/资源），尽管我尝试撤消此更改以查看它是否是原因，并且错误仍然发生。
老实说，我不确定。这本应该是一个微不足道的长达一小时的任务，结果变成了两天令人头疼的事情。

这是调用后记录的实际错误

[_persistentStoreCoordinator addPersistentStoreWithType:NSSQLiteStoreType configuration:nil URL:self.mainURL options:storeOptions error:&error]

其中 storeOptions 是 { NSInferMappingModelAutomaticallyOption = 1; NSMigratePersistentStoresAutomaticallyOption = 1; } 并且由于某种原因有两个：一个用于文件 .Model.sqlite.migrationdestination_41b5a6b5c6e848c462a8480cd24caef3 另一个用于文件 Model.sqlite，大概是迁移过程的一部分。（代码=134 110，基础代码=134 100）

创建这个新版本时我是否遗漏了一些明显的东西？还有其他要清理的缓存或隐藏文件吗？我确实注意到，当创建一个新的 What.xcdatamodel 时，Xcode 中的“放弃所有更改...”会留下该文件，所以我要格外小心地删除测试运行并检查 Xcode 外部的“git status”。

我对错误消息持怀疑态度，因为我可以将 xcdatamodeld 的“当前版本”切换回 2.5，看到文件打开得很好，将“当前版本”切换到 2.6，看到它失败，然后以可预测的成功来回切换/失败。它显然能够打开 2.5 文档，只是在尝试将它们迁移到 2.6 时无法打开。
