It’s a common misconception to think that German is the language spoken in Switzerland. In fact, people in Switzerland speak Swiss German which depending on dialect can be very different than standard German. Swiss German has a different grammar, different words and quite different pronunciation to Hochdeutsch (High German). It’s probably easier to learn Swiss German after learning German first, but it’s not impossible to learn Swiss German straight away. If that’s what you’re interesting in then I recommend https://swiss-german.com website where you can find Swiss German movies, books, tv shows, textbooks, songs and other resources which can help you in learning this foreign language.
