Lexical or Preprocessor Issue happens when using Core Data: '.Friend.h' file not found

I am writing functions of iOS Core Data. I have one Entity named "Friend", its Codegen is Category/Extension. I have written my own Friend subclass as NSManagedObject. I am facing an issue that Lexical or Preprocessor Issue, '.Friend.h' file not found in file Friend_CoreDataProperties.h which is auto generated.

After I manually correct .Friend.h to Friend.h, there will be another similar issue happening: .Friend+CoreDataProperties.h not found in file CoreDataTest+CoreDataModel.h

enter image description here

I can manually correct it as well, and it will build through and work fine. But each time the program is cleaned and rebuilt, the issue will comes out again because these code are automatically generated.

Solution

  • After recreating another Core Data App, I found out that the Current Product Module is avoiding human generation and placing that dot before that h file importing line. Once I delete the Current Product Module, everything goes fine!

    I have no idea why this happens, and how to deal with this problem in a correct way. Anyone who has the knowledge about this please help.
