code 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.

#import "Quote.h"

@implementation Quote

- (NSString *) randomQuote {
    if (_quotes == nil){
  _quotes = [[NSArray alloc] initWithObjects:@"1", @"2",
  @"3", nil];
  }
    return _quotes;
}

@end

If the issue of my code is a typo just let me know, but if it something i'm doing fundamentally wrong just give me a hint!

hmm the method has a return type of NSString but you are returning an NSArray. that could be part of the problem.

It's asking you to implement the quotes getter method, not the randomQuote method. As Stone Preston suggested, it should be returning an NSArray instead of NSString. Otherwise everything else inside the method looks correct.
