stringByAppendingString

Hi Guys-

What's wrong here? Can't get this to pass Task 3 of the NSString Challenge:

NSString *color = @"purple";
NSString *preference = @"My favorite color is";
NSString *favorite = [color stringByAppendingString:preference];

Keep getting: favorite as wrong value...

You are appending preference to color which results in "purpleMy favourite color is ".

You should call the method on preference and pass color as the parameter:

NSString *favorite = [preference stringByAppendingString:color];
