Refactoring into a Model : Challenge

Why isn't my code working ?!:

<p>- (NSArray *) quotes {
    if (_quotes == nil) {
  _quotes = [[NSArray alloc] initWithObjects:@"Hey, @"Hi", @"Hello", nil];
  }
  return _quotes;
  }</p>

When formatting code, you need to use backticks ( ` ) not single quotes ( ' ). Ive formatted your code for you so it appears correctly in the forum. The backtick key is just below the esc key on my keyboard. For more information on code formatting, see this post

_quotes = [[NSArray alloc] initWithObjects:@"Hey, @"Hi", @"Hello", nil];

you are missing a closing double quote for your Hey string:

  _quotes = [[NSArray alloc] initWithObjects:@"Hey", @"Hi", @"Hello", nil];

that should fix it.

Than a lot for you help. How annoying that you keep looking for you code for sometime trying to figure out what's wrong with your logic when it's just a typo or syntax error. Can'e even imagine when i start to make bigger applications.

Finding bugs and syntax errors is an art and takes practice. Eventually it will become easier and easier to find mistakes. Finding mistakes is especially tough in the code challenges since it doesn't tell you when you make an syntax error like Xcode does. You could write challenge code in Xcode first to help with catching syntax errors like this. I would also recommend trying to answer questions on the forum to help with learning to identify bugs and errors.
