in our schooltimes, girls and boys who spoke about än Summervogel were taught in definite terms that this is än Schmätterling
I have never seen the Herrgöttli until about two or three years ago, and only in one particular place in Oerlikon. It may have come from Bern but very common in Zürich it is not yet
Even it it seems to be easy to speak english only (because most of the swiss people here will understand you) please try to speak our language. No Swiss would ever go to a country like UK or US expecting everyone to speak/understand german ;-)
Use Pingu to learn Swiss German. It's the only way
Do the Swiss really appreciate it when you try to speak Swiss German with them? Because I know I'm gonna sound really terrible and probably butcher it. It's a similar situation in Singapore with Singlish...if a foreigner tried speaking it with me I'd be really happy (and amused), but I do know people who thought that if a foreigner couldn't speak it properly they couldn't be bothered with them. I didn't agree, I mean, we all have to start from somewhere, right?

you can find it at Orel Fuessli for about CHF 70. my German was actually not that great (ok, it's still not that great) when I started with the book, so I used it as an excuse to improve my German, as well.
Imagine English is German and Scottish is Swiss German
Here's my experience:
(1) Don't listen to people who say Swiss German is "JUST a dialect". It's not just a dialect, and it's not like Scottish. It's the native language of most Swiss. They speak it all times, even in many formal situations. They consider standard German a foreign language. So yes, it is a good idea to learn it! Unless you are planning to only read books and magazines and not socialize with locals. "Asking them to speak German with you" only works if there're 1-3 Swiss around you. If there's a party of 10-15 there's no chance they're going to stick to standard German for more than 1 min, especially after a round of drinks. And even when they do, they behave like this guy.
(2) However, it is true that it's simply easier to learn Swiss German when you know standard German at B1/B2 level. That is because there are very few resources for learning Swiss German in English, but there are quite a lot in standard German. Here's one that helped me quite a bit . Also after you understand the standard German grammar and know the basic vocabulary, it will be easier for you to understand Swiss German grammar and vocabulary because they're similar.
You don't need to practice German (yeah I know it's difficult to practice it with the Swiss). Just learn it enough to understand texts and grammar, then you can move on to learning Swiss German.
(3) There are also Swiss German courses, but I think they're also usually offered only to people with at least B1 level of German.
(4) I also recommend you to find a language tandem, for example for Swiss German / English exchange. I meet every week or two for Swiss German / Russian exchange. A good place to find a tandem if you want to meet offline is Couchsurfing.org.
(5) Sign up to Swiss memes and jokes on Facebook, Instagram, Twitter etc. (e.g. "SwissMeme")
Good luck!
