What is it?

This is a Swift client library for the OpenAI REST API, installable through Swift Package Manager. It provides typed request and response models for endpoints including Responses, Chat Completions, image generation and editing, speech synthesis and transcription, embeddings, moderations, files, models and the Assistants beta.

Requests can be made with async/await, closure callbacks or Combine, and in-flight calls can be cancelled through the task, the returned cancellable request, or the Combine subscription. Streaming is supported for chat and speech output. The library also includes support for MCP (Model Context Protocol) tools and structured outputs defined either by hand, from a Swift type, or as a dictionary schema.

The package can also be pointed at other providers that expose an OpenAI-compatible API, using a relaxed parsing option in the configuration. The README notes that API keys should stay on a backend server rather than in client-side apps.

Key features

  • 01Typed models for Responses, Chat Completions, images, audio, embeddings and moderations.
  • 02Async/await, closure and Combine call styles with request cancellation.
  • 03Streaming for chat completions and speech generation.
  • 04Structured outputs from hand-written, Swift-derived or dictionary JSON schemas.
  • 05MCP tool integration for Chat Completions requests.
  • 06Configurable host, timeout, organization ID and custom headers.

Use cases

  • Adding OpenAI chat or image generation to an iOS or macOS app through a backend proxy.
  • Building a Swift server-side tool that transcribes audio or generates speech via the API.
  • Calling OpenAI-compatible providers from Swift code using the same client interface.
  • Extracting structured JSON from text using typed Swift schemas.
