I'm not quite sure what the question is asking for, but I think your code should look like this? '''

  • (NSArray *) quotes {

if (_quotes == nil) _quotes =[[NSArray alloc]initWithObjects: @"This is hard", @"That is ok", nil]; return _quotes; }

'''

I recommend giving the OP code that scopes the if statement in curly braces to help avoid further errors.

I agree with Peter's answer. Peter's code looks like this with those:

- (NSArray *) quotes {

    if (_quotes == nil) {
       _quotes = [[NSArray alloc] initWithObjects: @"This is hard", @"That is ok", nil];
   }

   return _quotes;
}

Make sure _quotes is listed in your Quote.h file too, Keith. Cheers!
