Code Challenge: NSString

In the 3rd task in NSString code challenge we are asked to combine the 2 variable using the stringByAppendingString method. Below is my code. This looks correct to me. Please, help.

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

This code is straight from the apple docs and looks the same to me.

NSString *errorTag = @"Error: ";
NSString *errorString = @"premature end of file.";
NSString *errorMessage = [errorTag stringByAppendingString:errorString];

Your solution is technically right. The accepted answer requires an additional space at the end of your preference NSString. I think Amit Bijlani indicated in another thread that this will be fixed.

Oh sorry. I looked. I must have not looked far enough. Thanks!

if you want to skip it just add like this, other then that your solution is right.

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