We do have one small language, the Kven language(https://en.wikipedia.org/wiki/Kven_language), which is a sort of "Finnish structure, but with lots of borrowed Norwegian words. But for all intents and purposes, it very much sounds like Finnish.
It basically sounds like the language a Finnish person that has lived their whole life in Norway, and then starts to mix words because they forgot the Finnish words.
But that's about it. I know there are some other dialects, too, but these are all very small-scale languages that are either extinct, or will be extinct in some decades.
Much easier for Finns to learn Swedish, that for Swedes to learn Finnish, IMO. I speak Norwegian and Finnish (lived in Finland when I was young)
