why is my code wrong

Declare a property named 'shoppingList'. Make it an NSArray and use the modifiers 'nonatomic' and 'strong'.

ViewController.h 
#import "UIViewController.h"

@interface ViewController : UIViewController

@property (strong, nonatomic) NSString *shoppingCart;

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

@implementation ViewController

- (void)viewDidLoad {
    [super viewDidLoad];

    // Add your code below!
}
 -(IBAtion) showshoppingList {
  NSArray *list=[[NSArray alloc] initWithobjects:@"nonatomic.",@"strong.",nil];
  }

@end

Hi Leonard,

Your H File should look like this - 

#import "UIViewController.h"

@interface ViewController : UIViewController

@property (strong, nonatomic) NSString *shoppingCart;

@property (strong, nonatomic) NSArray *shoppingList;

@end

Hope this helps.

Keep it up!!

Thanks,
