Um... I didn't do anything wrong... Please explain.

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

Note: I'm not a formatting genius, but this originally was on different lines, not stuck 2gether.

The stringByAppendingString: method appends the parameter NSString to the NSString the method was called on.

You're not appending the strings in the correct order. You're appending preference to color and that results in "PurpleMy favorite color is ".

You should append the string the other way around...

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