Pretty excited for this. Looks like a good alternative to Erlang or Akka with the native performance / low resource utilization of Swift. Erlang lacks strong typing and Akka is DSL-hell. Both Erlang and Akka/JVM are GC languages whereas Swift uses atomic reference counting. Looks like they've open-sourced a transport [0] and are adding support for distributed tracing as well [1, 2], which is a huge aid for system operators and debugging.

Apple is investing a lot in it, but Swift is much younger than Rust (especially as an open source project). There is a working group that meets every few weeks to shepherd the various projects. Most of the recent activity has been (AFAICT) about orchestration. Well, that and transitioning projects to use async/await and structured concurrency. Here's some recent activity in the Swift on server space: - the proposal for distributed actors is currently in-review (https://github.com/apple/swift-evolution/blob/main/proposals...) - a metrics API for backends like Graphite, Prometheus, etc. (https://github.com/apple/swift-metrics) - HTTP/2 support for SwiftNIO (https://github.com/apple/swift-nio-http2) - a new service discovery API (https://github.com/apple/swift-service-discovery) - a new distributed tracing API (https://github.com/appl
