ios - "Class not found, using default NSManagedObject"AppName 中有特殊字符

Question

当我在 App-Name 中使用“-”字符时，出现以下错误:

CoreData: warning: Unable to load class named "<AppName>.<ClassName>" for entity <ClasName>. Class not found, using default NSManagedObject instead.

我将 CoreData 与子类 NSManagedObjects 一起使用，因此我将 DB 文件中的所有实体类名称命名为 AppName.ClassName。

App-Names 中是否禁止使用此字符？

谢谢!

我不确定这是否适用于 NSManagedObjects，但 Apple 书籍“Using Swift with Cocoa and Objective C”(在“Mix and Match”标题下，指出:

Naming Your Product Module

The name of the Xcode-generated header for Swift code, and the name of the Objective-C bridging header that Xcode creates for you, are generated from your product module name. By default, your product module name is the same as your product name. However, if your product name has any non-alphanumeric characters, such as a period (.), they are replaced with an underscore (_) in your product module name. If the name begins with a number, the first number is replaced with an underscore.”

这显然是为了桥接 header ，但我只是想知道类似的规则是否适用于 CoreData 类名。
