We all as of March 1, 2017, it has been revealed by several sources who had the Nintendo Switch console in hand, that it does, in fact, use friend codes to add new players to their friend list. The friend codes are part of the Nintendo Network ecosystem because of the New Nintendo 3DS/3DS handhelds. People seem to have forgotten that fact.
The friend code input screen is updated from the 3DS version. Now, this may seem like a step back for some. That is not the case. Now with the My Nintendo service, you can now link your Nintendo Network ID to social media services like Facebook, Twitter, and Google. You can know add your friend Tiffany through social media and no friend codes. Easy Peasy!! Also if you play Super Mario Run, Miitomo, or Fire Emblem Heroes, you can add your friends to the Nintendo Switch as well.
The world can calm down now. Hopefully, you will realize even though Nintendo has made some mistakes, they are trying to make things less complicated with The Nintendo Switch. We will update this as the console is released.
