Challenge Task 3 in Inheritance

The question reads: 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'.

my answer is:

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

Its giving an error

Im sure this is the correct answer, could this be a bug on Treehouse's side?

Hey Roulse,

I completed the Inheritance exercises myself and had the same answer you have and everything passed smoothly. Then I went ahead and literally copied and pasted the answer you provided into the interface and it passed as well. So it has to be a bug or a glitch somewhere, have you tried opening a new tab or reopening the browser and starting it over?

Welcome to Treehouse!

Remember, the syntax for a property definition is:

@property(attributes) Classname *variable;

It looks like you have a slight syntax error in your code, which should read like:

@property(nonatomic, strong) Ruby *ruby;

Happy coding,

Ken

Hi Ken

Thanks for responding, appreciate your help. I have written my code as above but it still gives a syntax error.
