^-- Made a DI lib for Swift. Maybe I'll port a Kotlin version.

what does your library do that Koin, Kodein, Dagger, and Guice don’t already do

This one is for Swift so it doesn't use reflection or compile time weaving.

Instead it holds references to functions. It might be interesting to try the same approach in Kotlin, however to work it relies on Swift property wrappers.

I think there's always room for another lib, at the very least for one's own amusement, but social coding can be fun too.
