I thought I had all three things in my shopping list.

Bummer! Make sure you're adding all three items to the shopping list!

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!
    NSArray *shoppingList = [[NSArray alloc] initWithObjects:@"toothpaste", @"bread", @"eggs", nil];
}

@end

Try self.shoppingList instead of NSArray *shoppingList

Hi there Caleb,

The challenge is looking for the use of the keyword 'self', in accessing the 'shoppingList' property.

self.shoppingList = [[NSArray alloc] initWithObjects:@"toothpaste", @"bread", @"eggs", nil];
