composition challenge

In a code challenge, I've been trying to add a ruby (from Ruby.h) to a new class Bling. I've tried every different ordering of the following code but I keep getting an error that I'm doing something wrong with the property. Can anyone point out the error to me? Thanks, Eric

import "Ruby.h"

@interface Bling : NSObject

@property (nonatomic strong) Ruby *ruby;
ruby = [[Ruby alloc] init];

@end

I haven't done it in a while, so my answer might be wrong, but I used to do a little iOS development, so I'll try to answer.. I'm pretty sure you need to separate the things in parentheses with commas, like this:

#import "Ruby.h"
@interface Bling : NSObject
@property (nonatomic, strong) Ruby *ruby;
ruby = [[Ruby alloc] init];
@end

''' Objective-C @class Ruby; @interface Bling : NSObject @property (nonatomic, strong) Ruby *ruby; @end '''
