This news makes it easy. I’m starting the engines on this…
It makes sense for them to build their services using Swift instead of something like Go and the Swift-on-server team has been doing a lot of work to get swift in a usable state on Linux. Having a thriving opensource (starting with a package index) makes a lot of sense to them for that.
My only problem with Swift is personal taste and experience. I tried it on linux few times (admittingly few years ago now) and generally I wasn't a fan. Go and Rust solve all the problems that Swift could have solved for me, so I didn't bother. But just like node got an entire class of developers into server side programming, Swift could be apples approach to get their iOS and MacOS developers a way to easily write server side code in swift as well
