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

This video tutorial covers the implementation of a PATCH route to allow users to edit their profiles, such as changing their email or password. It explains the PATCH method in the context of CRUD operations and contrasts it with the PUT method. The tutorial also includes steps to validate user updates, ensuring only allowed changes are made, and demonstrates testing the functionality using Postman.
