Introducing Temporal Swift SDK: Building durable and reliable workflows

Building reliable distributed systems requires handling failures gracefully, coordinating complex actions across multiple services, and ensuring long-running processes complete successfully. Rather than develop these resiliency features into every application or service you develop, an alternative approach is to use workflows. Workflows encapsulate your code so it runs durably and handles many common failure scenarios.

Temporal is widely used for workflow orchestration across many languages. With the release of the SDK, Temporal is now available for Swift developers building production cloud services.

The Temporal Swift SDK is now open source, bringing Temporal's durable workflow orchestration to Swift developers for reliable distributed systems.

Temporal handles failures gracefully by resuming workflows automatically after crashes, using a separation of deterministic workflows (defining logic) and idempotent activities (performing work). The SDK leverages Swift’s async/await, structured concurrency, strong typing, and macros for a seamless, low-boilerplate experience.

It enables building resilient applications like data pipelines and payment processing without custom retry or state management code. Developers can explore documentation, example projects, and the repository to implement workflows and activities efficiently.
