OpenAI API Client Library in Swift

This is a community-maintained library to access OpenAI HTTP API's. The full API docs can be found here: https://beta.openai.com/docs

Installation 💻

Manual

Copy source files into your own project

Swift Package Manager (Preferred)

You can use Swift Package Manager to integrate the library by adding the following dependency in your Package.swift file or by adding directly within Xcode

.Package(url: "https://github.com/adamrushy/OpenAISwift.git", majorVersion: 1)

Example Usage 🤩

Import the module in your application.

import OpenAISwift

Set your API token from creating one here.

let openAI = OpenAISwift(authToken: "TOKEN")

Create a call to the completions API, passing in a text prompt.

openAI.sendCompletion(with: "Hello how are you", maxTokens: 100) { result in // Result<OpenAI, OpenAIError>
    switch result {
    case .success(let success):
        print(success.choices.first?.text ?? "")
    case .failure(let failure):
        print(failure.localizedDescription)
    }
}

The API will return an OpenAI object containing the corresponding text items.

You can also specify a different model to use for the completions. The sendCompletion method uses the text-davinci-003 model by default.

openAI.sendCompletion(with: "A random emoji", model: .gpt3(.ada)) { result in // Result<OpenAI, OpenAIError>
    // switch on result to get the response or error
}

For a full list of the supported models see OpenAIModelType.swift. For more information on the models see the OpenAI API Documentation.

OpenAISwift also supports Swift concurrency so you can use Swift’s async/await syntax to fetch completions.

do {
    let result = try await openAI.sendCompletion(with: "A random emoji")
} catch {
    print(error.localizedDescription)
}

Contribute ❤️

I created this mainly for fun, we can add more endpoints and explore the library even further. Feel free to raise a PR to help grow the library.
