welcome to sweden!
I can understand you think swedish is difficult because of all peculiar grammar. I wish you luck.
In swedish there are a lot of new borrowed words from especially english, but also from middle east or balkan.
The word is the very same but the grammar will be in swedish, like the word cache. But after a while people find swedish words for the same thing and use them also. sometimes the swedish word wins, sometimes not, and the borrowed word wins. for the word cache you will often hear the word gömma(noun). and in my opinion these two words is used 50/50
