HELP! Creating a Data Model: Task 2 of 3 Challenge

I kept getting the error that I need to make sure all three items are added to the shopping list. Please help! I'm not sure what I'm missing here.

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

you created a property called shoppingList in the previous task, so access that property. right now you are creating a local variable. you can access the property named shoppingList using self.shoppingList

#import "ViewController.h"

@implementation ViewController

- (void)viewDidLoad {
    [super viewDidLoad];

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

@end

you could also achieve this by using the following code:

self.shoppingList = @[@"toothpaste",@"bread",@"eggs"]
