The task states: 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.

you need to implement a new method called quotes. you put your code in the method called randomQuote which is why its not passing. Other than that your code looks correct, just put it inside a new method called quotes:

#import "Quote.h"

@implementation Quote


- (NSArray *) quotes { 
  if (_quotes == nil){ 
   _quotes = [[NSArray alloc] initWithObjects: @"dbdb", @"kbdd", @"sadfkn", nil]; 
 } 
 return _quotes; 
}
- (NSString *) randomQuote {

    return @"Some Quote";
}

@end
