SwiftUI and Node.js Full Stack - Build Twitter - iOS 16 - Like and Unlike Tweet Server-Side

This video tutorial covers the implementation of a like functionality for tweets, similar to the follow feature. It explains the backend process of adding and removing user IDs from a tweet's likes array, setting up server connections, and handling HTTP requests. The tutorial also demonstrates integrating these functions into the tweet cell view model and testing the functionality. The next video will focus on updating the UI based on server state changes.
