ios - 核心数据错误 1550

Question

我正在使用 CKSIncrementalStore。

我的数据模型是:

所有属性都是可选的。

我可以创建一个客户端，然后创建一个项目，将客户端添加为关系。

像这样:

    project.client = client

只要我只将相同的客户端添加到一个项目中，它就可以正常工作。每次我尝试将客户端添加到多个项目时，都会出现以下错误:

我将 NSManagedObjectContext 存储在共享管理器中，因此我在任何地方都使用相同的 NSManagedObjectContext。

可能出了什么问题？ :)

这是图书馆的问题。 (:
