Seeking Feedback on My Upcoming eBook: From Zero to MVP with SwiftUI

I am in the process of writing an eBook titled "From Zero to MVP with SwiftUI." The book aims to provide a guide for iOS developers, especially those enthusiastic about SwiftUI and who wants build their first app as a portfolio. It takes the reader on a journey from writing their very first line of code to deploying a real world app. The core of the book revolves around building 'an expense splitting app. The aim isn't just to teach SwiftUI, but to provide a framework of understanding that could help readers build many more apps in the future. Here's a glimpse of what's inside: 1. Mastering the basics of Swift and SwiftUI. 2. Understanding and implementing design patterns like MVVM. 3. Debugging in Xcode 4. Core Data Integration. 5. Internationalisation for a global audience. 6. Analytics, In-App Purchases, Unit and UI Testing. 7. Accessibility Before I launch, I would like to get feedback from this community: What are you most interested in learning or understanding better when it comes to SwiftUI and build real world app? Are there any specific topics or areas you feel would be essential to cover? My goal is to make this as valuable as possible for budding and experienced iOS developers alike. I genuinely appreciate any insights or constructive criticism. Thank you in advance for your time and feedback!
