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

This video tutorial covers the implementation of the 'unlike' functionality for tweets, similar to the 'unfollow' feature. It involves setting up a PUT route, checking if a tweet is already liked, and removing the user's ID from the likes array. Error handling is emphasized to prevent issues like unliking a tweet multiple times. The tutorial concludes with testing the functionality using Postman to ensure it works as expected.
