OpenAI

Swift implementation of OpenAI API

Supported:

• Files
• Chat Completion
• Assitants

Getting Started

Add the following dependency clause to your Package.swift:

dependencies: [
    .package(url: "https://github.com/swiftnative/OpenAI.git", from: "1.0.0")
]

Usage

You can find demo app inside and tests to get an idea of the usage.

It's build with URLConfig to be native and flexible.

API provide URLRequest for making call, and all Codable models you need.

public extension OpenAI.Chat {

  /// - Documents: https://platform.openai.com/docs/api-reference/chat/create
  /// - Response: `ChatCompletion`
  static func completion(_ body: ChatCompletionRequest) -> URLRequest {
    URLRequest.with(.OpenAI.base) {
      $0.method = .post
      $0.path = "/v1/chat/completions"
      $0.bodyModel = body
    }
  }
}

Just 3 steps to interact with OpenAI

/// Create URLRequest
let createCompletionBody = ChatCompletionRequest(model: .OpenAI.gpt_4o_2024_05_13,
                                                     messages: [.system(systemMessage),
                                                                .user(userMesage)
                                                     ],
                                                     tools: [.function(function)],
                                                     toolChoice: .function(name: function.name))

let createCompletion = OpenAI.Chat.completion(createCompletionBody)

/// Make Call
let response = try await URLSession.shared.response(for: createCompletion)

/// Hadle Response
let completion: ChatCompletion = try response.decode()

Feel free to

• create you own simple codable model to decode to, if you don't need the full ones.
• extend api, if you need more.
