12,151 PointsHow to extract object from NSArray and store it into a string?
seems like Im not pointing correctly...
#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];
// Add your code below!
self.shoppingList = @[@"toothpaste", @"bread", @"eggs"];
self.shoppingCart = [*shoppingList objectAtIndex: 2];
}
@end

21,900 PointsYou had 2 compiler errors:
- It has to be "self.shoppingList" not just shoppingList (because it's a property of a class)
- You don't need a pointer symbol here
So the following is correct:
self.shoppingCart = [self.shoppingList objectAtIndex: 2];
But you were close! Happy coding!
