Hi 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! :sparkles:
