I thought I did allocate and initialize _quotes.

Bummer! Remember to allocate and initialize the instance variable '_quotes' and return it from the method named 'quotes'.

Quote.h 
@interface Quote : NSObject

// Add property here

@property (strong, nonatomic, readonly) NSArray *quotes;

- (NSString *) randomQuote;

@end
Quote.m 
#import "Quote.h"

@implementation Quote

- (NSString *) randomQuote {
if (_quotes == nil){
   _quotes = NSArray [[NSArray alloc] initWithObjects:@"Happy, Happy, Happy", @"Your gullible", @"Say cheese", nil]; 
    }
    return _quotes;
}

@end

your code is almost correct, with a few minor issues:

you added your code to the randomQuote method, you are supposed to implement a new method. called quotes that returns an NSArray. also, you had an extra NSArray out in front of your alloc call (NSArray [[NSArray alloc]) . remove that:

@implementation Quote

- (NSArray *) quotes {
if (_quotes == nil){
   _quotes = [[NSArray alloc] initWithObjects:@"Happy, Happy, Happy", 
   @"Your gullible", @"Say cheese", nil]; 
    }
    return _quotes;
}


- (NSString *) randomQuote {

    return @"Some Quote";
}

@end

and remove the read only attribute from your property. it messes up the challenge and wont accept it with it in there:

@property (strong, nonatomic) NSArray *quotes;

Okay, did what you said and I'm still getting the same message, can you find anything else wrong with the code?

Still isn't working, I even tried to copy and paste the code and had no luck with it.
