Swift OpenAPI Generator

Generate Swift client and server code from an OpenAPI document.


OpenAPI is an open specification for documenting HTTP APIs.

Swift OpenAPI Generator is a Swift package plugin that can generate the ceremony code required to make API calls, or implement API servers.

Repository organization

The Swift OpenAPI Generator project is split across multiple repositories to enable extensibility and minimize dependencies in your project.

swift-openapi-generator (source, docs) provides the plugin.

swift-openapi-runtime (source, docs) provides a library with common types and abstractions used by the generated code.

See the generator in action in Meet Swift OpenAPI Generator from WWDC23.

Choose one of the transports listed below, or create your own by adopting the ClientTransport or ServerTransport protocol:

Repository Type Description
apple/swift-openapi-urlsession Client Uses URLSession from Foundation.
swift-server/swift-openapi-async-http-client Client Uses HTTPClient from AsyncHTTPClient.
swift-server/swift-openapi-vapor Server Uses Vapor.
swift-server/swift-openapi-hummingbird Server Uses Hummingbird.
