Stuck on code challenge 2/3 in how to create a class...Making a simple iPhone app

I can't figure out the problem...Here is my code

```#import "Quote.h"

@implementation Quote

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

@end

So according to this, the quotes var is an array. The objective is to alloc/init the quotes var only if it is nil and init it with three strings of your liking.

It's really hard to read the code you have in the format that you have it, but from what I'm seeing, you're supposed to be returning a String but instead you're returning an NSArray.

These are the instructions.

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.

So is the _quotes var an NSArray or String?

It's an nsarray with 3 nsstring objects in that array.
