错误：重新定义＆＃39;类别＆＃39;作为不同种类的符号

我有一个NSManagedObject类问题，我的类（类别）在基础中重新定义了一个类似乎，但基金会在同一个项目的两个应用程序中！

我的项目有两个目标，这两个Mac OS x应用程序共享一个DataModel和相关的Class。一个应用程序，即主应用程序，有望成为应用程序商店另一个是一个实用程序应用程序，用于从XML生成一个sqlite数据库，以便与主应用程序一起发货。

主应用程序编译并运行。实用程序应用程序在此处稍稍抛出错误。我在这个＆＃34;重新定义＆＃34;仅在实用程序应用程序中出现问题。重命名类别类别，是解决这个问题的方法，但事实主要的应用程序编译和运行，告诉我，我可以通过寻找其他地方来解决它。我希望这是足够的数据让别人告诉我在哪里看。 $（TARGET_NAME）== SqlFromXml_HM ==产品名称

问题实用程序具有： 0目标依赖项 11编译源 0链接二进制文件库 5复制捆绑资源

Category.h开始

//  Category.h

#import <CoreData/CoreData.h>
@class Recipe;

@interface Category : NSManagedObject {

请勿拨打您的界面Category。该名称由ObjC运行时使用。

将其称为更具体的内容，例如RecipeCategory。

ManagedObject类由两个OS X目标共享。一个应用程序只有类重新定义错误。修复不需要重命名我的NSManagedObject？
