When should you use an actor?

The author explains when to use Swift actors: only for non-Sendable shared state that needs atomic mutations and can’t run on an existing actor/MainActor.

He warns that actors force asynchronous access and add complexity, so prefer classes or MainActor unless those conditions truly hold.

Introducing Temporal Swift SDK: Building durable and reliable workflows

Franz Busch announced the open-source Temporal Swift SDK, which brings durable workflow orchestration to Swift with async/await, structured concurrency, strong typing, and macros.

The post highlights durable execution (workflows resume after failures), a clear split between deterministic workflows and idempotent activities, and links to documentation and examples with an open invitation to contribute.

Swift Tip

Working with arrays or nested objects?

Use dump() instead of print() - it displays the data in a clear, structured, and readable format.
