What am I doing wrong here? Thanks

In the viewDidLoad method, retrieve the string eggs from the shoppingList array and store it in shoppingCart. Hint: use the 'objectAtIndex' method.

ViewController.h 
#import "UIViewController.h"

@interface ViewController : UIViewController

@property (strong, nonatomic) NSArray *shoppingList;

@end
ViewController.m 
#import "ViewController.h"

@implementation ViewController

- (void)viewDidLoad {
    [super viewDidLoad];

    // Add your code below!
    self.shoppingList = [[NSArray alloc]initWithObjects: @"toothpaste", @"bread", @"eggs", nil];
    self.shoppingCart = [self.shoppingList objectAtIndex: 2];
}

@end

You should tell us what is the error message or what your compiler saying ! , check 

@property (strong, nonatomic) NSArray *shoppingList;

// OR 
@property (strong, nonatomic) (NSArray *)shoppingList;

Well, I quit Xcode and as I have search through my error message it took me to Apple development site and offering me all kinds of dev tools and education for $99 dollars a year. Should I still learn from a someone who barely can teach? Thanks for looking into my issue.
