Hi Luis. please be mindful about the challenge description.

(Note: Don't set the values directly as strings, but rather use something like 'objectAtIndex' to reference the original array.)

Hence, the right way to do this is by adding the value, one line at a time.

NSArray *shoeOrder= @[@"Charles Smith", @(9.5), @"loafer",@"brown"];
NSMutableDictionary *shoeOrderDict=[[NSMutableDictionary alloc] init];
shoeOrderDict[@"customer"] = [shoeOrder objectAtIndex: 0];
shoeOrderDict[@"size"] = [shoeOrder objectAtIndex: 1];
shoeOrderDict[@"style"] = [shoeOrder objectAtIndex: 2];
shoeOrderDict[@"color"] = [shoeOrder objectAtIndex: 3];

hope it helps
