Hi Haengun,

NSString *favorite = [preference stringByAppendingString:color];

would be right and you mispelled NSString by mistake.

Challenge task 3 of 3

"Declare a third NSString variable named 'favorite' and assign a concatenated string to it by appending the variable named 'color' to the variable named 'preference'. (Remember to use the method 'stringByAppendingString')."

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

There's a great video here in the forum section on the right "Tips for asking questions" that might help you with posting your questions and code on the forum.
