why is it better to @class than #import in that case

I've tried it and it's working so why in this particular case it is better?

Hello Gautier,

There are several reasons why modules (using @) were created as a better solution to preprocessor #include and #import. The benefit I've read and heard most is it is more efficient.

Here's a blog post that explains more in detail, including the history of #include and #import.

I hope this helps!
