XCode: CoreData.Framework strange behavior with id

Question

I have found a strange lines like:

id *_optimizationHints; <- in NSManagedObjectModel.h

id* _cd_snapshots; <- in NSManagedObject.h

id** _kvcPropertyAccessors; <- in NSEntityDescription

id* _debuggingRecords; <- in NSManagedObjectContext.h id *_cachedObsInfoByEntity; <- in NSManagedObjectContext.h

When i try to compile a project with ARC option, i see error like this: Pointer to non-const type 'id' with no explicit ownership

What's wrong? As i read from similar questions, i need to replace id * -> id

But this is Main CoreDate.Framework!

I can't understand this.

Can anybody explain this 'joke'?

I encounter similar issue this morning. Seems the problem is due to the Core Data has been built in somehow. When we import the CD framework, I have to go to Building Phases to add dependency framework instead of drag and drop directly from Finder. Hopefully this is helpful
