Let me guess, you were a child so don't really know what the bureaucracy is like there. Switzerland is actually much more progressive (good luck doingt anything online in Germany!!).

Quite easy, just use the Bürgerbüro online portal.

I lived in Geneva from 26 to 28 years old, as mentioned in other replies, come back to Switzerland every time I manage to, and have several good Swiss friends.

I also had to help a friend of mine newly moved into Baden in 2018 to settle in, so I know what bureaucracy she had to face until she was 100% done with everything and could carry on with her life having a proper bank account, address, mobile phone, internet, new car registration, the whole package.
