Now that Core Data got support for ordered relationships the KVC ordered accessor methods…

-countOf<Key>
-objectIn<Key>AtIndex:
-<key>AtIndexes:
-get<Key>:range:
-insertObject:in<Key>AtIndex:
-insert<Key>:atIndexes:
-removeObjectFrom<Key>AtIndex:
-remove<Key>AtIndexes:
-replaceObjectIn<Key>AtIndex:withObject:
-replace<Key>AtIndexes:with<Key>:

…should be auto-generated at runtime by Core Data in the same way as…

-add<Key>Object:
-add<Key>:
-remove<Key>Object:
-remove<Key>:

…are.

Comments

I'm using Core Data with an entity with an ordered relationship to another entity.

Core Data is generating the signature, "- removeAtIndexes:" in the header file. Yet when I attempt to invoke the method it states, unrecognized selector. Core Data should not generate the declaration if it doesn't provide an implementation. If this is somehow intended to be useful to the developer, the declaration should at least be flagged to indicate its not implemented. Otherwise it is difficult to determine from the generated header what methods are valid and which are not.
