quotes method not initializing and no idea why not

What is wrong here? I am being asked to allocate, initialize and return the quote array declared as a property in the the 'h' file. 

// 'quote.h'

@interface Quote : NSObject

@property(strong,nonatomic) NSArray *quote;

- (NSString *) randomQuote;

@end


//-------------------------------------

// 'quote.m'

#import "Quote.h"

@implementation Quote

- (NSArray *) quotes{
  if (_quotes == nil){
    NSArray _quotes = [[NSArray alloc] initWithObjects:@"one", @"two", @"three", nil];
  }
  return _quotes;
}

- (NSString *) randomQuote {

    return @"Some Quote";
}

@end

Hi Justin,

You have NSArray at the start of your allocation line which doesn't need to be there as the instance variable _quotes will be assigned that type because of it's parent quotes.

_quotes = [[NSArray alloc] initWithObjects:@"one", @"two", @"three", nil];

To add to Chris Upjohn's (correct) answer:

Make sure you double check everything for typos. In the code blocks you included within your forum post, I can see that the @property in the header file is defined as "quote" whereas you typed "quotes" in your implementation.

Additionally, within the screenshots you provided, you forgot one of the double-quotes when you were declaring your strings.

I also noticed that the issue Chris pointed out is not present in the screenshots. Overall, I think you just need to pay more attention to consistency and proper syntax.

Thanks for additional comments Alex. Walking away from my computer once every 20 hours could help with focusing and uncross my eyes.
