核心数据 - 预填充数据时不兼容的模型

Question

我在 Xcode 的新项目中添加预填充数据时遇到此错误。

}

我试过...重置内容和设置..数据模型的模型版本控制..但没有奏效...但是如果那里只有一个实体，那么就不会出现这样的错误。这个错误出现在存在不止一个实体。

我有一个类似的问题（虽然不是完全相同的问题），这是由于我在创建 SQLite 数据库文件后对模型进行了更改而引起的。我不得不从 Debug 文件夹中删除 SQLite 数据库（应该在你的应用程序编译到的地方创建），然后再次构建应用程序。使用我更新的模型创建了一个新的 SQLite 数据库。希望这是有道理的，并有所帮助。

这个和其他建议的解决方案可以在 stackoverflow 的其他地方找到：

The model used to open the store is incompatible with the one used to create the store
