Ugh. Tell me about it. For one who uses cash regularly, this is becoming more and more apparent. I can though confirm there's still a long way to go, and people like me can still get around.
I haven't got 'Swish', but I'm fully aware what it is (and partially how to use it) but no one close to me uses it. With the launch of new banknotes and soon also coins, I won't quit using cash anytime soon.
Another interesting fact they mention is how banks are cashless. There's only ONE main bank that openly handles cash, and they're going to remove cash handling from a bunch of offices this autumn (thus right now). I remember when this all started around 2008-2009 and I think it's very wrong by them to reject cash all together, making it vital to abide to their systems and let them do whatever they want. What if another financial crisis happens?
So, Got cash? Then don't come here. Use your card instead.
