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

This video tutorial explains how to fetch notes from a database using a GET request. It covers the importance of asynchronous requests and error handling using try-catch blocks. The tutorial demonstrates implementing async functions and testing the GET request with Postman and a browser. It concludes with an overview of CRUD operations, highlighting the need for update and delete functionalities in future videos.
