Hey isn't this a correct answer?

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

Why won't it go through?

Update: Really just a question for the course makers. I think the test conditions are a bit off...

EDIT:I put objective-c so it highlights in the right way. Check out how i did it by looking at edit and see what i did. -Aurelian

I think you've got the strings reversed. Appending preference to color would result in the string "PurpleMy favorite color is ".

I believe this would give you "Purple My favorite color is ". Perfectly acceptable if you're Yoda. :-P if it helps, think of stringByAppendingString as a very long form of a + sign like you'd use in javascript or Java.
