What does this LLVM 1.5 warning mean? “protocol qualifiers without 'id' is archaic”

Question

I\'ve just tried compiling an iOS project using the the LLVM 1.5 compiler (included in XCode 3.2.3), and I got a lot of new warnings, including several like this:

Answer 1

Archaic: extremely old or extremely old-fashioned.

The warning means a protocol qualifier (i.e. ) without an id is deprecated. The delegate parameter's type should look like:

- (id)initWithContext:(NSManagedObjectContext *)context
          coordinator:(NSPersistentStoreCoordinator *)coordinator
             delegate:(id)delegate;
