Emacs News is a linkdump sort of weekly newsletter that takes about an hour and half each week, which I've been doing for 10.5 years because it's so much fun to read about the cool stuff people do with Emacs. A lot of it comes from Planet Emacslife, an RSS aggregator that I run. I also help organize an online Emacsconf on a shoestring budget (USD 250 of hosting costs for year-round static sites plus two days of 1.5 tracks, well worth it as a way of getting stuff out of people's heads and encouraging conversation). Last year, due to various things happening, I ended up hosting the 1.5 days with mostly just one other organizer and the second afternoon all by myself, and that was still surprisingly manageable. :) The BigBlueButton server we maintain for that also gets used for hosting three meetups every month, which is a good way of keeping the infrastructure active so I don't have to re-set it up each year. I announce the meetups in Emacs Calendar, which feeds back into Emacs News. None of these pieces cost very much and the time definitely feels like fun hobby time rather than work. They're great excuses to tinker with Emacs and hang out with fascinating people. :) Emacs lends itself to automating so much stuff, so there's a lot of compounding benefit going on. Your mileage may vary if the topic is more blah.
I see there are several Swift newsletters already, so you probably have a good start. I'd be delighted to swap questions and share notes!
