Swift Google Drive Client

Basic Google Drive HTTP API client that does not depend on Google's SDK. No external dependencies.

• Authorize access
• List files
• Get file info
• Get file (download)
• Create file (upload)
• Update file (upload)
• Delete file
• Get user info (about)

📖 Usage

Use Swift Package Manager to add the GoogleDriveClient library as a dependency to your project.

Configure OAuth 2.0 Client ID using Google Cloud Console. Use iOS application type.

Configure your application so that it can handle sign-in redirects. For an iOS app, you can do it by adding or modifying CFBundleURLTypes in Info.plist:

<key>CFBundleURLTypes</key>
<array>
  <dict>
    <key>CFBundleTypeRole</key>
    <string>Editor</string>
    <key>CFBundleURLName</key>
    <string></string>
    <key>CFBundleURLSchemes</key>
    <array>
      <string>com.googleusercontent.apps.1234-abcd</string>
    </array>
  </dict>
</array>

Create the client:

import GoogleDriveClient

let client = GoogleDriveClient.Client.live(
  config: .init(
    clientID: "1234-abcd.apps.googleusercontent.com",
    authScope: "https://www.googleapis.com/auth/drive",
    redirectURI: "com.googleusercontent.apps.1234-abcd://"
  )
)

Make sure the redirectURI contains the scheme defined earlier.

The package provides a basic implementation for storing vulnerable data securely in the keychain. Optionally, you can provide your own, custom implementation of a keychain, instead of using the default one.

import GoogleDriveClient

let keychain = GoogleDriveClient.Keychain(
  loadCredentials: { () async -> GoogleDriveClient.Credentials? in
    // load from secure storage and return
  },
  saveCredentials: { (GoogleDriveClient.Credentials) async -> Void in
    // save in secure storage
  },
  deleteCredentials: { () async -> Void in
    // delete from secure storage
  }
)
let client = GoogleDriveClient.Client.live(
  config: .init(...),
  keychain: keychain
)

▶️ Example

This repository contains an example iOS application built with SwiftUI.

• Open GoogleDriveClient.xcworkspace in Xcode.
• Example source code is contained in the Example Xcode project.
• Run the app using the GoogleDriveClientExampleApp build scheme.
• The "Example" tab provides UI that uses GoogleDriveClient library.
• The "Console" tab provides UI for browsing application logs and HTTP requests.

The example app uses Dependencies to manage its own internal dependencies. For more information about the Dependencies library check out official documentation.
