Hello everyone.

Will someone please guide me through this code challenge? I don't understand how to create a variable and don't understand id. Thank you in advanced.

Hi Arnav,

If you don't know how to create a variable, I would re-watch earlier videos in the Objective-C basics course. That is a basic building block and you should feel comfortable with that before getting as far as Dynamic typing.

That said, you can create (declare) variables like:

int age; or NSString *favoriteColor;

or both declare and assign a value at once, like: NSString *zipCode = @"97205"; or id faveFood = nil;
