Apple is not a good product, believe me, sorry. I will suggest you to test app Kodi because that is what i using to IPTV. But i can not confirm about EPG for Switzerland, but i tested sweden, norway, finland, UK, USA and germany and work good.
It worked only in one day and is stopped now. I can not get multi-EPG anymore. I have tried with many different methods and it helped nothing. It will work fine to use EPG from one country, but i will get all in one EPG because Enigma2 boxes is sensitive and it will stop to work if i will try...
