OpenAIKit is a Swift package used to communicate with the OpenAI API.
Add the dependency to Package.swift:
dependencies: [
...
.package(url: "https://github.com/dylanshine/openai-kit.git", from: "1.0.0")
],
targets: [
.target(name: "App", dependencies: [
.product(name: "OpenAIKit", package: "openai-kit"),
]),It is encouraged to use environment variables to inject the OpenAI API key, instead of hardcoding it in the source code.
# .env
OPENAI_API_KEY="YOUR-API-KEY"
OPENAI_ORGANIZATION="YOUR-ORGANIZATION"Create a OpenAIKit.Client by passing a configuration.
var apiKey: String {
ProcessInfo.processInfo.environment["OPENAI_API_KEY"]!
}
var organization: String {
ProcessInfo.processInfo.environment["OPENAI_ORGANIZATION"]!
}

// Generally we would advise on creating a single HTTPClient for the lifecycle of your application and recommend shutting it down on application close.
let eventLoopGroup = MultiThreadedEventLoopGroup(numberOfThreads: 1)
let httpClient = HTTPClient(eventLoopGroupProvider: .shared(eventLoopGroup))
defer {
// it's important to shutdown the httpClient after all requests are done, even if one failed. See: https://github.com/swift-server/async-http-client
try? httpClient.syncShutdown()
}
let configuration = Configuration(apiKey: apiKey, organization: organization)
let openAIClient = OpenAIKit.Client(httpClient: httpClient, configuration: configuration)If you don't want to use SwiftNIO you can use URLSession.
let urlSession = URLSession(configuration: .default)
let configuration = Configuration(apiKey: apiKey, organization: organization)
let openAIClient = OpenAIKit.Client(session: urlSession, configuration: configuration)The OpenAIKit.Client implements a handful of methods to interact with the OpenAI API:
import OpenAIKit
let completion = try await openAIClient.completions.create(
model: Model.GPT3.davinci,
prompts: ["Write a haiku"]
)- Chat
- Models
- Completions
- Edits
- Images
- Embeddings
- Files
- Moderations
- Fine-tunes
- Speech to text
- Function calling
If the request to the API failed for any reason an OpenAIKit.APIErrorResponse is thrown.
Simply ensure you catch errors thrown like any other throwing function
do {
...
} catch let error as APIErrorResponse {
print(error)
}
