Introducing Swift Service Lifecycle

It is my pleasure to announce a new open source project for the Swift server ecosystem, Swift Service Lifecycle. Service Lifecycle is a Swift package designed to help server applications, also known as services, manage their startup and shutdown sequences.

Swift Service Lifecycle is a new open-source Swift package designed to simplify and standardise the management of startup and shutdown sequences for server applications.

It provides a framework-agnostic solution to handle tasks like initialising resources and freeing them safely, reducing errors in server workflows. Developers create a ServiceLifecycle instance, register LifecycleTasks for startup and shutdown, and the library executes them in order, with a default signal handler for INT and TERM to manage graceful shutdowns.

An example demonstrates registering a SwiftNIO EventLoopGroup and a DatabaseMigrator for controlled startup and shutdown. The package enhances safety and reusability for server-side Swift applications.
