A Swift implementation of the AWS Lambda Runtime API for developing and deploying Lambda functions written in Swift. It uses an embedded asynchronous HTTP client based on SwiftNIO and offers a layered API from simple closures to complex, performance-sensitive event handlers.

Use cases

• write AWS Lambda functions in Swift
• deploy Swift serverless functions to AWS
• handle AWS service events in Lambda handlers
• stream responses from Lambda functions
• test Lambda functions locally
• build performance-sensitive event handlers in Swift

When to choose

• your team writes Swift and wants serverless functions on AWS Lambda
• you need a custom Lambda runtime with async SwiftNIO-based HTTP handling
• you want SwiftPM plugins and tooling for building and deploying Lambda functions

When to avoid

• you use a language with first-class Lambda support like Python, Node.js, or Go
• you are not deploying to AWS Lambda
• you need a general-purpose web server rather than a Lambda runtime
