In this tutorial, we dive into the practical application of OpenTelemetry in an iOS project built with SwiftUI. We demonstrate how to set up the OpenTelemetry SDK, generate spans, and send them to a configured OpenTelemetry collector.

Our example application displays a random sentence every few seconds. Each sentence generation process is instrumented with OpenTelemetry spans, which include an attribute representing the word count of the sentence.

By following along, you'll gain a practical understanding of distributed tracing and how to leverage OpenTelemetry in your own iOS projects.
