In Swiss German, you wouldn't normally say something that literally means "have a good day." People do say "gnüss de schöni Tag" (enjoy the nice day), which is very casual. You could also say "ne schöni Tag" or "ne schöni Tag noa." But generally the normally Swiss German good-bye is "Wiadaluaga." Even so, it's also just fine to use the High German "Auf Wiedersehen."
Hello=Hola Good-bye=Adiós
