Good luck getting a debit card without an address.

If you're living abroad and visiting you'd probably already have a debit card, no need to open a new one for a visit. This is only relevant for Swish because it's not something someone living outside of Sweden would likely already have.

The rely was to a Swede who lives abroad and comes back to visit Sweden.

Presumably they have cards they can bring with them on the trip that work in Sweden even though their address is outside Sweden?

I know when I travel abroad I just take and use my normal cards without a problem.
