An open-source Swift package designed for effortless interaction with OpenAI's public API.
SwiftOpenAI is an open-source Swift package that streamlines interactions with all OpenAI's API endpoints, now with added support for Azure, AIProxy, and Assistant stream APIs.
To interact with OpenAI services, you'll need an API key. Follow these steps to obtain one:
- Visit OpenAI.
- Sign up for an account or log in if you already have one.
- Navigate to the API key page and follow the instructions to generate a new API key.
For more information, consult OpenAI's official documentation.
Remember that your API key is a secret! Do not share it with others or expose it in any client-side code (browsers, apps). Production requests must be routed through your backend server where your API key can be securely loaded from an environment variable or key management service.
SwiftOpenAI has built-in support for AIProxy, which is a backend for AI apps, to satisfy this requirement. To configure AIProxy, see the instructions here.
- Open your Swift project in Xcode.
- Go to
File->Add Package Dependency. - In the search bar, enter this URL.
- Choose the version you'd like to install.
- Click
Add Package.
To use SwiftOpenAI in your project, first import the package:
import SwiftOpenAIThen, initialize the service using your OpenAI API key:
let apiKey = "your_openai_api_key_here"
let service = OpenAIServiceFactory.service(apiKey: apiKey)You can optionally specify an organization name if needed.
let apiKey = "your_openai_api_key_here"
let oganizationID = "your_organixation_id"
let service = OpenAIServiceFactory.service(apiKey: apiKey, organizationID: oganizationID)That's all you need to begin accessing the full range of OpenAI endpoints.

/// Controls how the model responds to function calls. none means the model does not call a function, and responds to the end-user. auto means the model can pick between an end-user or calling a function.

/// A list of tools the model may call. Currently, only functions are supported as a tool. Use this to provide a list of functions the model may generate JSON inputs for.
public var tools: [Tool]?
/// Modify the likelihood of specified tokens appearing in the completion.
/// Accepts a json object that maps tokens (specified by their token ID in the tokenizer) to an associated bias value from -100 to 100. Mathematically, the bias is added to the logits generated by the model prior to sampling. The exact effect will vary per model, but values between -1 and 1 should decrease or increase likelihood of selection; values like -100 or 100 should result in a ban or exclusive selection of the relevant token. Defaults to null.

/// [See more information about frequency and presence penalties.](https://platform.openai.com/docs/guides/gpt/parameter-details)
public var presencePenalty: Double?
/// An object specifying the format that the model must output. Used to enable JSON mode.
/// Setting to `{ type: "json_object" }` enables `JSON` mode, which guarantees the message the model generates is valid JSON.
///Important: when using `JSON` mode you must still instruct the model to produce `JSON` yourself via some conversation message, for example via your system message. If you don't do this, the model may generate an unending stream of whitespace until the generation reaches the token limit, which may take a lot of time and give the appearance of a "stuck" request. Also note that the message content may be partial (i.e. cut off) if `finish_reason="length"`, which indicates the generation exceeded `max_tokens` or the conversation exceeded the max context length.
public var responseFormat: ResponseFormat?
/// This feature is in `Beta`. If specified, our system will make a best effort to sample deterministically, such that repeated requests with the same `seed` and parameters should return the same result.
/// Determinism is not guaranteed, and you should refer to the `system_fingerprint` response parameter to monitor changes in the backend.
public var seed: Int?
/// Up to 4 sequences where the API will stop generating further tokens. Defaults to null.
public var stop: [String]?
/// If set, partial message deltas will be sent, like in ChatGPT.

/// What sampling temperature to use, between 0 and 2. Higher values like 0.8 will make the output more random, while lower values like 0.2 will make it more focused and deterministic.
/// We generally recommend altering this or `top_p` but not both. Defaults to 1.
public var temperature: Double?
/// An alternative to sampling with temperature, called nucleus sampling, where the model considers the results of the tokens with top_p probability mass. So 0.1 means only the tokens comprising the top 10% probability mass are considered.
/// We generally recommend altering this or `temperature` but not both. Defaults to 1

let completionObject = try await service.startChat(parameters: parameters)AIProxy is a backend for AI apps that proxies requests from your app to OpenAI. You can use this service to avoid exposing your OpenAI key in your app. We offer AIProxy support so that developers can build and distribute apps using SwiftOpenAI.
SwiftOpenAI supports proxying requests through AIProxy with a small change to your integration code.
Instead of initializing service with:
let apiKey = "your_openai_api_key_here"
let service = OpenAIServiceFactory.service(apiKey: apiKey)
Use:
#if DEBUG && targetEnvironment(simulator)
let service = OpenAIServiceFactory.service(
aiproxyPartialKey: "hardcode_partial_key_here",
aiproxyDeviceCheckBypass: "hardcode_device_check_bypass_here"
)
#else
let service = OpenAIServiceFactory.service(
aiproxyPartialKey: "hardcode_partial_key_here"
)
#endif
The aiproxyPartialKey and aiproxyDeviceCheckBypass values are provided to you on the AIProxy developer dashboard.
aiproxyDeviceCheckBypass token leak into a distribution
build of your app (including TestFlight distributions). Please retain the conditional compilation
checks that are present in the sample code above.
AIProxy uses Apple's DeviceCheck to ensure that requests received by the backend originated from your app on a legitimate Apple device. However, the iOS simulator cannot produce DeviceCheck tokens. Rather than requiring you to constantly build and run on device during development, AIProxy provides a way to skip the DeviceCheck integrity check. The token is intended for use by developers only. If an attacker gets the token, they can make requests to your AIProxy project without including a DeviceCheck token, and thus remove one level of protection.
This constant is intended to be included in the distributed version of your app. As the name implies, it is a partial representation of your OpenAI key. Specifically, it is one half of an encrypted version of your key. The other half resides on AIProxy's backend. As your app makes requests to AIProxy, the two encrypted parts are paired, decrypted, and used to fulfill the request to OpenAI.
Please see the AIProxy integration guide
