Observability in Server-Side Swift

on YouTube ↗31m

" summary

Demos show Swift observability built from three API packages — SwiftLog, SwiftMetrics, SwiftDistributedTracing — exported via OTLP over HTTP and gRPC with TLS/MTLS using the Swift Hotel 1.0 backend. Bootstrapping becomes a one-line bootstrap that returns a service task; Hummingbird adds logs, metrics and spans with three middleware lines. A minimal /hello server emits a counter, log and span; in the microservice demo Grafana surfaces a 100% error rate on empty-cart traces and toggling an experimental feature flag immediately fixes the bug.
