Swiss German vs high (proper) German

A few examples:

German: Guten Abend
Swiss German: Guten Abig
English: Good evening (and yes, they write all nouns with capital letters...why? you tell me!)

German: Wo bist du?
Swiss German: Wo bisch?
English: Where are you?

German: Küchekasten
Swiss German: Chuchichästli (not sure about spelling, but neither are the Swiss :)
English: kitchen cupboard

On top of it all some words are completely different like:

German: Fahrrad
Swiss German: Velo
English: bicycle

German: arbeiten
Swiss German: schaffen
English: work

Can you tell I'm struggling?
