Swift REST Client Generator for Google APIs

This project contains Swift code that generates a API clients from Discovery Documents produced by the Google API Discovery Service.

It is experimental work-in-progress, but provides a good start at calling many Google APIs from Swift. Our focus is on supporting calls from server-side and command-line Swift applications, but calls from any platform with Swift support should be possible.

Usage

Running google-api-swift-generator will list all available Google APIs and generate a Swift client file in your current directory.

./google-api-swift-generator

  2) Accelerated Mobile Pages (AMP) URL API
  3) Access Approval API
  4) Access Context Manager API
  5) Ad Exchange Buyer API
  6) Ad Exchange Buyer API II
  7) Ad Experience Report API
  8) Admin Reports API

It is also possible to run the generator with Discovery Documents downloaded from the Discovery Service by passing the json file as argument:

Running the following creates a file named discovery-document-filename.swift in your current directory.

google-api-swift-generator <discovery-document-filename.json>

This project also includes an experimental CLI generator that generates command-line interfaces for APIs. These CLIs depend on the generated client libraries and are produced with the google-cli-swift-generator command. Running the following writes a CLI main.swift to standard output:

google-cli-swift-generator <discovery-document-filename.json>

The Examples directory contains several example clients including scripts for generating both client libraries and CLIs.
