SwiftUI and Node.js Full Stack - Build Twitter - iOS 16 - Edit Profile and Follow Buttons

The video tutorial addresses a bug in user profile navigation where unauthorized users can edit profiles. It introduces a solution by adding an 'isCurrentUser' boolean property to the user model and implementing logic to check if the displayed user is authenticated. The tutorial demonstrates how to adjust the UI based on authentication status, such as showing or hiding the edit profile button. It emphasizes the importance of using computed properties for local UI control and concludes with designing a follow button for non-authenticated users.
