What is wrong with my code here?

I'm trying to add elements to an array which was declared as a property in the header file. I'm doing this:

[self.shoppingList addObjects:@"toothpaste",@"bread",@"eggs",nil];

What's 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!
   [self.shoppingList addObjects:@"toothpaste",@"bread",@"eggs",nil];
}



@end

Add the objects during initialization using the initWithObjects method, and you'll be good to go.
