Hi, Ankit, there're couple of issues here.

  • your code has 2 pairs of [], but you only need one pair.
  • The challenge requires you to append color to preference, your code is doing the opposite, appending preference to color.
NSString *favorite = [preference stringByAppendingString: color];

Hope it helps.
