How should I start learning Swiss German?
Any suggestion, books, audios, or videos which are helpful for a complete beginner learning Swiss German are highly appreciated!

Question

Answer

I would not recommend you to learn Swiss German only or learn Swiss German first.
You may want to learn standard German first which is "Hochdeutsch". If you only learn to speak Swiss German then you won't be able to write or read German text.

Answer

There are some resources out there, Pimsleur got something too:  http://www.pimsleur.com/learn-swiss-german

However, the written language is mostly hochdeutsch and you need to know that too.
