Google Generative AI SDK for Swift

The Google Generative AI SDK for Swift allows developers to use state-of-the-art Large Language Models (LLMs) to build language applications.

Once you’ve added the Swift package to your Swift application, you can call the API as follows:

import GoogleGenerativeAI

let palmClient = GenerativeLanguage(apiKey: "YOUR API KEY")
response = try await "Hello")

Getting Started

This repository contains a few sample apps. To try them out, follow these steps:

  1. Check out this repository.
    git clone
  2. Follow the instructions on the setup page to obtain an API key.
  3. Open and build one of the examples in the Examples folder.
  4. Paste the API key into the API_KEY property in the PaLM-Info.plist file.
  5. Run the app.

Using the PaLM SDK in your own app

To use the Swift SDK for the PaLM API in your own apps, follow these steps:

  1. Create a new Swift app (or use your existing app).
  2. Right-click on your project in the project navigator.
  3. Select Add Packages from the context menu.
  4. In the Add Packages dialog, paste the package URL into the search bar:
  5. Click on Add Package. Xcode will now add the GoogleGenerativeAI to your project.

Initializing the API client

Before you can make any API calls, you need to import and initialize the API client.

  1. Import the GoogleGenerativeAI module:
    import GoogleGenerativeAI
  2. Initialize the API client:
    let palmClient = GenerativeLanguage(apiKey: "YOUR API KEY")

Calling the API

Now you’re ready to call the PaLM API’s methods.

Note: All API methods are asynchronous, so you need to call them using Swift’s async/await.

For example, here is how you can call the generateText method to summarize a Wikipedia article:

let prompt = "Summarise the following text:"

let response = try await palmClient.generateText(with: prompt)

if let candidate = response?.candidates?.first, let text = candidate.output {
