> The linux version of swift replicates a large number of native mac frameworks using whatever mix of C and C++ gets the job done.
Note that this is changing, on Darwin and Linux alike. Foundation.framework is transitioning from being a Swift interface over a C / Objective-C implementation to an Objective-C interface over a Swift implementation.

It also uses a local SQLite db instead of a separate MySQL server, which makes deployment quite trivial (git clone && make run). The web client is still built with React, I've been thinking of rebuilding it with a single .html file and minimal JavaScript.

I've seen this one, "Move away from BoringSSL", actively in development (PR opened two weeks ago):

Such a shame. Swift has many beautiful language features.
I give swift a try every once in a while.
Problems of my last attempt:
- The Swift REPL (lldb to be precise) depends on libpython-dev (v3.8). WSL (ubuntu 22.04) comes with 2.7 and 3.10, so the lldb dependency depends on an old python version. The fix was to copy the 3.10 binary to the directory where lldb expects it, and rename it to libpython3.8.so. It seems that it's backwards compatible so it worked on my machine.
- I tried to compile and statically link a hummingbird (web framework, more light weight than vapot, https://github.com/hummingbird-project/hummingbird) hello-world example. I had a liking error. Luckilly someone in the swift forums helped me. The problem was that my package.swift file had the "-static-stdlib" flag only as a swiftSettings. It needed to be also a linkerSetting.
In the end I was able to build my example. But at this point I already spent multiple days debugging problems that are unrelated to my applicationn or the Swift language.
It's a shame because I see its potential. Fixing the (linux/windows) tooling problems would probably only take "some" developers. Apple has near infinite money and could sponsor them if they wanted to., but they gain little by it. Besides them, not many are invested in it.
