What is openai?

This repo is a Swift package that lets iOS and macOS developers talk to OpenAI's APIs from their apps. Instead of writing all the networking and data-handling code from scratch to send requests to OpenAI and parse responses, a developer can add this package and get a ready-made set of tools for doing things like generating text with GPT models, creating images with DALL-E, transcribing audio, and more. At a high level, the package wraps OpenAI's public API in Swift-friendly types and functions. A developer initializes it with their OpenAI API key, then calls methods like chats or completions with a structured query specifying what they want. The package handles building the request, sending it to OpenAI, and returning the result in a clean Swift format. It supports both one-shot requests (where you wait for the full response) and streaming (where text comes back token by token, useful for chat-like interfaces). It also supports function calling, where the AI can ask the app to run a specific function and feed the result back into the conversation. This is designed for Swift developers building Apple-platform apps who want to integrate AI features. For example, someone building a note-taking app could use it to summarize text, a language-learning app could generate conversational responses, or a creative tool could generate images from text prompts. The package covers a broad range of OpenAI capabilities: text completions, chat, image generation and editing, audio transcription and translation, text-to-speech, embeddings, content moderation, and model listing. A notable practical detail: the README emphasizes that API keys should never be exposed in client-side code. For production apps, requests should be routed through a backend server that securely holds the key. This means the package is most safely used in server-side Swift contexts or with a proxy layer, rather than shipping keys directly in an iPhone app.
