SwiftUI and Node.js Full Stack - Build Twitter - iOS 16 - Create Notes with POST Requests

This video tutorial covers the implementation of the 'create' functionality in a CRUD application, allowing users to add notes. It guides through setting up the UI with a text field and button, using a sheet to display the add note view, and coding the POST request to save notes to an API. The tutorial also addresses handling server responses and errors, and concludes with testing the functionality.
