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

This video tutorial covers the implementation of an unfollow function, building on a previous episode where a follow function was created. The tutorial guides viewers through the process of coding the unfollow function, handling edge cases, and testing the function using Postman. It also addresses common issues and debugging techniques, ensuring a comprehensive understanding of the unfollow functionality in an API context.
