Treehouse TeacherHi there! I received your request for assistance. You're doing just fine and when you see the answer, it will probably make sense immediately.
The line you're looking for is:
NSString * myRide = [[NSString alloc]init];
This both allocates an NSString and initializes it. According to the Apple developer documentation the init
of an NSString returns an initialized string object containing no characters.
Hope this helps!
