After that, and IBM losing interest, Apple did hire a few competent people (including contributors to Netty and Akka) to build the Swift Server Workgroup.
But I don't know why I'd pick Swift on the server when Rust is better in almost every dimension, with a thriving and more community-driven ecosystem.
I think it's not about that but about dogfooding Swift on the server. Apple uses Go, Java etc for a lot of its server components and refused to invest in hiring people that would extend the ecosystem for server Swift.
Thats the problem.
