Could you tell me how to let 'ruby' belongs to 'Ruby'? I tried but couldn't figure it out...

The question is,

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'.

Gem.h 
@interface Gem : NSObject

@end
Ruby.h 
@interface Ruby : Gem

@end
Bling.h 
@interface Bling : NSObject
@property ruby : Ruby;

@end

You are using the wrong syntax. The correct syntax to declare the property is: 

@property (strong, nonatomic) Ruby *ruby;
