API package for code generated by Swift OpenAPI Generator.

Swift OpenAPI Generator Runtime

This library provides common abstractions and helper functions used by the client and server code generated by Swift OpenAPI Generator.


It contains:

  • Common types used in the code generated by the swift-openapi-generator package plugin.
  • Protocol definitions for pluggable layers, including ClientTransport, ServerTransport, and middleware.


Add the package dependency in your Package.swift:

    url: "https://github.com/apple/swift-openapi-runtime",
    .upToNextMinor(from: "0.1.0")

Note that this repository does not have a 1.0 tag yet, so the API is not stable.

Next, in your target, add OpenAPIRuntime to your dependencies:

.target(name: "MyTarget", dependencies: [
    .product(name: "OpenAPIRuntime", package: "swift-openapi-runtime"),

The next step depends on your use case.

Using Swift OpenAPI Generator for code generation

The generated code depends on types from this library. Check out the adoption guides in the Swift OpenAPI Generator documentation to see how the packages fit together.

Implementing transports and middlewares

Swift OpenAPI Generator generates client and server code that is designed to be used with pluggable transports and middlewares.

Implement a new transport or middleware by providing a type that adopts one of the protocols from the runtime library:

  • ClientTransport
  • ClientMiddleware
  • ServerTransport
  • ServerMiddleware

You can also publish your transport or middleware as a Swift package to allow others to use it with their generated code.
