A swift OpenTelemetry client


This package includes several libraries. The OpenTelemetryApi library includes protocols and no-op implementations that comprise the OpenTelemetry API following the specification. The OpenTelemetrySdk library is the reference implementation of the API.

Libraries that produce telemetry data should only depend on OpenTelemetryApi, and defer the choice of the SDK to the application developer. Applications may depend on OpenTelemetrySdk or another package that implements the API.

Please note that this library is currently in development, and you should be careful before using in production environments.

Adding the dependency

opentelemetry-swift is designed for Swift 5. To depend on the opentelemetry-swift package, you need to declare your dependency in your Package.swift:

.package(url: "https://github.com/open-telemetry/opentelemetry-swift", from: "0.6.0"),

and to your application/library target, add OpenTelemetryApi or OpenTelemetrySdkto your dependencies, e.g. like this:

.target(name: "ExampleTelemetryProducerApp", dependencies: ["OpenTelemetryApi"]),


.target(name: "ExampleApp", dependencies: ["OpenTelemetrySdk"]),

Current status

Currently Tracing, Metrics and Baggage API's and SDK are implemented, also OpenTracing shim, for compatibility with existing Opentracing code.

Implemented traces exporters: Stdout, Jaeger, Zipkin, Datadog and OpenTelemetry collector

Implemented metrics exporters: Prometheus, Datadog, and OpenTelemetry collector


The package includes some example projects with basic functionality:

  • Logging Tracer - Simple api implementation of a Tracer that logs every api call
  • Simple Exporter - Shows the Jaeger an Stdout exporters in action using a MultiSpanExporter. Can be easily modified for other exporters
  • Prometheus Sample - Shows the Prometheus exporter reporting metrics to a Prometheus instance
