Hi, I am stuck on this question. Any help would be greatly appreciated. Thanks!
Let's add a few items to our grocery list. Switch to the implementation file and in the viewDidLoad method, initialize the shoppingList array to the following items: 'toothpaste', 'bread' and 'eggs'.
This is what I thought would have worked...
#import "UIViewController.h"
@interface ViewController : UIViewController
@property (strong, nonatomic) NSString *shoppingCart;
@property (strong, nonatomic) NSArray *shoppingList;
@end
#import "ViewController.h"
@implementation ViewController
- (void)viewDidLoad {
[super viewDidLoad];
}
NSArray *list = [[NSArray alloc] initWithObjects: @"toothpaste", @"bread", @"eggs", nil];
self.shoppingList.text = [list objectAtIndex: 1];
@end

@implementation ViewController
- (void)viewDidLoad { [super viewDidLoad];
NSArray *shoppingList = [[NSArray alloc] initWithObjects: @"bread", @"toothpaste", @"eggs" , nil];
self.shoppingList.text = [list objectAtIndex: 1]; }
@end

12,216 PointsYou're not in the viewDidLoad method. If you look closely you put your code outside the terminating brace.

9,258 PointsI was stuck as well. I just googled stuffs and I looked at the editor tab which gives you the details of the errors in your code. The code below will work:
@property (strong, nonatomic) NSArray *shoppingList;
self.shoppingList = @[@"toothpaste", @"bread", @“eggs"];
_shoppingCart = [self.shoppingList objectAtIndex:2];
