What on earth am I doing wrong :(!

It's asking me to assign eggs as a string with objectAtIndex to shoppingCart from the header file. I'm rather tired and might have missed something small please help!

(Side note, this code works in my Xcode simulator)

Thanks for any help.

ViewController.h 
#import "UIViewController.h"

@interface ViewController : UIViewController

@property (strong, nonatomic) NSString *shoppingCart;
@property (strong, nonatomic) NSArray *shoppingList;

@end
ViewController.m 
#import "ViewController.h"

@implementation ViewController

- (void)viewDidLoad {
    [super viewDidLoad];

    // Add your code below!
    self.shoppingList = [[NSArray alloc] initWithObjects: @"toothpaste", @"bread", @"eggs", nil];
    self.shoppingCart = [shoppingList objectAtIndex:2];
}

@end

Hi Phil,

You have a very small oversight in your code and that is you haven't prefixed shoppingList with self.

self.shoppingCart = [self.shoppingList objectAtIndex:2];

Happy coding!
