There are certainly books for Germans who emigrate to Switzerland about learning Swiss German (which is somewhat close to Swabian), because Swiss people reverse-discriminate: if you speak either Standard German, or any non-Swiss German accent / dialect, you will be treated with distrust (some people will be more tolerant of Austrians or South Germans, though). At the same time, if you try to speak Swiss German but don't so perfectly, people will also think you're being ridiculous. /shrugs (source: grew up in Switzerland)
