I'm trying to implement a method called 'quotes' which will only allocate and initialize if _quotes is 'nil'. I seem to have something wrong but I cannot figure it out. Please help!

Here is my code:

-(NSArray  *) quotes {
    if (_quotes == nil) {
        _quotes = [[NSArray alloc] initWithObjects:
                   @"It's Sunny Today",
                   @"It's cold",
                   @"It's hot", nil];
    }
    return _quotes;
}

There is nothing wrong with your code. Do you put it in the wrong spot? I copied and pasted your code into the .m file. Here is what the full code looks like. See if that helps.

#import "Quote.h"

@implementation Quote

-(NSArray *) quotes { 
if (_quotes == nil) { 
_quotes = [[NSArray alloc] initWithObjects: @"It's Sunny Today", @"It's cold", @"It's hot", nil]; 
} 
return _quotes; 
}

- (NSString *) randomQuote {

    return @"Some Quote";
}

@end

Hey Gareth, I guess it was an error in the treehouse compiler. I refreshed the page and attempted it again with EXACTLY the same code and it worked. Not going to lie it was driving me crazy though. Thank you for the help!
