I completely agree that a big problem is the difficulty to install Swift tooling on Unix.
I work in a cloud company called Clever Cloud, and we package our own Exherbo distributions for the exact environments we provide. As a Swift enthusiast, working a lot with Server Side Swift (mainly with Vapor), I proposed my colleagues to add Swift support.
Even though they are really experienced in Exherbo packaging, they told me it was a real pain to add Swift support, and paused it until it’s easier.
I think it’s by being present in front of people that SSS will be better known.
I really look forward to a Swift version easier to install.
