I can't retrieve my eggs, what am I doing wrong?

I can't seem to figure out what's wrong with my code

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];

self.shoppingList = [[NSArray alloc] initWithObjects:@"toothpaste", @"bread", @"eggs"]; 
self.shoppingCart  =[shoppingList objectAtIndex:2];
}
@end

Hey Kathleen,

I just had the same issue however I believe since unlike the FunFacts app where we initiated the Array within the implementation file and not as in the code challenge as a property in the header file you will need to call self on the shopping list as well

ex.

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