Need help on challenge 3!?

Finally, we have a class named 'Bling' which needs to have a property called 'ruby'. Switch over to 'Bling.h' and add a property named 'ruby' that belongs to the class 'Ruby'.

There is an error at thats... The 'ruby' property should be a pointer. Heres my code below.

Gem.h
@interface Gem : NSObject
@end
Ruby.h
@interface Ruby : Gem
@end
Bling.h
@interface Bling : NSObject
@property (nonatomic) Ruby ruby;
@end

Pretty closed, only missed the strong keyword, and the * here.

@interface Bling : NSObject
@property (nonatomic, strong) Ruby *ruby;
@end
