Confused on Data Collection

It is asking me to initialize the shoppingList array. I thought this was the way to do it. Please let me know what I'm doing wrong!

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

Hi Jac,

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];

Thanks appreciate your help!
