Switzerland has a massive foreign-born population compared to other places - their largest city is something like 30% foreign - yet very few problems caused by that even though those people often don't learn the local dialects or not even German/French at all. If it were actually a xenophobic society (spelled with PH not F in English) then they'd be having race riots all the time.

In practice Switzerland is one of the more accommodating societies in the world. Most Swiss people don't move far from where they grow up though, so often still have friends from school. It isn't a culture oriented towards chatting with strangers or making new friends at the drop of a hat, but that's not the same thing as xenophobia. Swiss who move abroad then back after many years experience the same difficulties with making new friends.
