What is wrong with my code?

Can anyone please tell me where is the wrong part in my code and can't get through this challenge?

Thanks!

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

I finally found the solution. Here is the correct code. self.shoppingList = [[NSArray alloc] initWithObjects:@"toothpaste",@"bread",@"eggs",nil];

Thanks for your time!

in your code you're creating a NEW array instead of filling the property you created in the header file.

change this: 

NSArray *shoppingList = ...

to this:

self.shoppingList = ...
