Can't solve challenge.

Switch to the implementation file and implement a 'quotes' method which will allocate and initialize the _quotes instance variable only if it is 'nil'. Initialize the array with any three strings.

My code is bellow: 

#import "Quote.h"

@implementation Quote

- (NSArray *) quotes {
    if ( _quotes == nil) {
  _quotes = [[NSArray alloc] initWithObjects:@"a", @"b", @"c", nil];
  return _quotes;
  }
}



- (NSString *) randomQuote {

    return @"Some Quote";
}

@end

Since you are implementing a getter method for your quotes property, you need to return it no matter what, not just if its nil. so move your return statement below the if statement:

- (NSArray *) quotes {
    if ( _quotes == nil) {
  _quotes = [[NSArray alloc] initWithObjects:@"a", @"b", @"c", nil];

  }
return _quotes;
}

Thanks Stone! How blind I was leaving the return inside the "if"!
