It says to add three items to a list. My code reads: self.shoppingList = @[@"toothpaste", @"bread", @"eggs", nil]

In the interface I created a property: @property (strong, nonatomic) NSArray *shoppingList

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 = @[@"toothpaste", @"bread", @"eggs", nil];

}

@end

Hi Kevin, you don't need the nil at the end of the array assignment here.

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