Distributed Tracing with Swift
summary
Project implements distributed tracing in server-side Swift using the Swift Distributed Tracing API and exports to back ends like Jaeger/OpenTelemetry and AWS X‑Ray. HTTP clients and frameworks are instrumented — the team forks and patches AsyncHTTPClient, Vapor, Soto to create and propagate spans. Tracing finds a 900 ms database call, and store app changes cut picking time from 45 to under 10 minutes. Swift 5.5 concurrency with task-local values removes manual context passing so span propagation becomes automatic.
