I can't seem to get this to work, have tried a lot of stuff and checked internet but it says everything I insert is wrong.

ViewController.h 
#import "UIViewController.h"

@interface ViewController : UIViewController

@property (strong, nonatomic) NSString *shoppingCart;

@property (nonatomic, strong) NSArray *shoppingList;

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

@implementation ViewController

- (void)viewDidLoad {
    [super viewDidLoad];

    // Add your code below!
    self.shoppingList = [@"toothpaste", @"bread", @"eggs"];
}

@end

Christian, it seems that you have working code but there is one thing you left out in the implementation. When you assign the array some items, you forgot the @ symbol before the first square bracket.

Here is the correct implementation:

ViewController.h 
#import "ViewController.h"

@implementation ViewController

- (void)viewDidLoad {
    [super viewDidLoad];

    // Add your code below!
    self.shoppingList = @[@"toothpaste", @"bread", @"eggs"];

@end

Christian, no problem! Even after months of programming, I still make syntax mistakes every day! I am glad that I could help!
