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

This video tutorial addresses a bug in a note-taking app where notes do not refresh after being added. The solution involves modifying the sheet properties to call the fetch notes function upon dismissal. The tutorial then introduces a delete functionality using an alert triggered by a long press gesture. The video covers error handling, ensuring the app does not crash when an ID is missing, and emphasizes the importance of refreshing the UI after deletion. The next video will focus on implementing the update functionality in the CRUD operations.
