Google Photos migration from Library API to Picker API in iOS

Migrating from the Google Photos Library API to the Picker API in iOS involves several key steps to ensure a smooth transition and maintain functionality. Here’s a step-by-step guide:

Steps to Migrate: Review API Changes: Understand the differences between the Library API and the Picker API. The Picker API focuses on securely selecting photos and videos, while the Library API is now more focused on managing content uploaded by your application1.

Update Authentication: Ensure that your application has the necessary OAuth 2.0 access token for the user. If not, initiate the OAuth 2.0 authorization flow to obtain one2.

Create a Picker Session: Initiate the Picker API flow by creating a new session. This will return a unique picker URI2.

Direct Users to Google Photos: Provide the picker URI to your users, either as a clickable link or a QR code. This securely opens the Google Photos app2.

Poll the Session: Periodically poll the session to check the status. Look for the mediaItemsSet property to return true, indicating the user has finished their selection.

List Selected Media Items: Once mediaItemsSet returns true, use the list method to get details about the selected media items.

Retrieve and Use Media Items: Fetch the content of the selected media items using the provided base URL and utilize them within your application.

Additional Considerations: Review Documentation: Familiarize yourself with the detailed Picker API reference documentation to understand all available methods and parameters.

Test Thoroughly: Ensure thorough testing of the new Picker API integration to confirm that it works seamlessly with your application.

By following these steps, you can effectively migrate from the Google Photos Library API to the Picker API in iOS, ensuring a secure and user-friendly experience for your users1.
