Am I doing wrong with this question?

My code is:

self.shoppingCart.text = [shoppingList objectAtIndex:2];

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 = [[NSArray alloc] initWithObjects:@"toothpaste",@"bread", @"eggs",nil];
    self.shoppingCart.text = [shoppingList objectAtIndex:2];
}

@end

Hey Khoi,

There is simply no need for you to access the '.text' property of NSString. It doesn't have one! When you're assigning(=) a string a value to a string you wont have to access the text property, because it is already in text format from where you're grabbing it from.

Now a different case would be if you were taking user input in a textfield or text box. then you would self.textField.text and assign it somewhere else.

To make a long story short, remove the . text property and see what happens.
