What is wrong with this statement? Stuck on code challenge

The challenge question is to initialize the shopping list array with 3 items.

NSArray *shoppingList = [[NSArray alloc]initWithObjects:@"toothpaste", @"bread", @"eggs", nil];

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 there,

You have already declared the property to be a NSArray so you don't need to do that again.

However, you need to access the property using the self keyword:

self.shoppingList = [[NSArray alloc] initWithObjects:@"toothpaste", @"bread", @"eggs", nil];

I hope that helps.

Steve.

Thanks! The error message that I got would have never led me to realize that I was declaring shoppingList again.

Glad it helped! :-)

Steve.
