Sure.
Swiss German isn’t a written language. It is oral only, and although some people do write in Swiss German in Whatsapp messages and on Reddit, they are simply typing phonetically, and I find it tiring to read. Books written by Swiss German writers, news articles and so on are written in what passes for German German”. The only difference is that we don’t use “ß” Like in “Straße”, but we use a double “s”, as in “Strasse”. And we use different vocabulary for certain things. We would say “Trottoir” instead of “Gehsteig” (=pavement), “Billet” instead of “Fahrkarte” (=public transport ticket), and so on. But a German would have no trouble reading it. They might just find some terms quirky.
Does anybody actually watch TV nowadays? I thought it was all streaming… And yes, we watch German films, and can communicate perfectly normally with Germans on social media platforms.
