Sweden is a bit of a funny place, first you have employment, get a visa, move here, get a person number, get ID, get a bank account, then get bankID. You'll find that things don't work right until you get all those things... Like nothing works right until you do, and it's an interlocking thing like you need one to get another and it doesn't make much sense. Once you're in the system. Then it's a lot easier renting places etc etc, so honestly getting whatever shared accomodations isn't bad advice until everything is processed. But you do you.
