Today, we'll be looking at how to create a simple SwiftUI screen for adding a new book to Firestore. Along the way, we will refactor our existing code and introduce a new view model. And since Peter likes to live on the bleeding edge, we will use some features Apple announced at WWDC 2020 just a few days ago.

The irony when a Google guy has the best Swift tutorials. Thanks Peter.

Excellent video series thank you. Could you demonstrate how to fetch and display a document that includes an array please? I can’t seem to work it out.

I forked the repo and sent the request. I am a novice programmer but I am really interested in making clean, easy to maintain, code. I used the Repo-VM-VM-View and added a search bar. Issues: Are the BookCellViewModel and BookListViewModel the best way to approach this? I tried to use this with the search bar to branch out and I am stuck. Side note: Can this series clarify Using Resolver and Disk like the MakeItSo finished repo and add google sign in with the same way of migrating data? thanks again Peter, and I hope I can keep progressing on these tutorials.

Do you have any videos for pagination with SwiftUI!? Nobody seems to be discussing the best practices for it!?

Excellent Tutorial! thanks for efforts. Can we avoid using Combine by building conditions in "save" function, like: if !(book.author == "") && !(book.title == "") && !(book.numberOfPages == 0), which could be much simpler?
