SOLVED: Day 54 (Bookworm): book.count label isn't updating

Forums > 100 Days of SwiftUI

My app no longer crashes when I add a book to the app, but the book.count label isn't updating.

Any thoughts as to why?

I'm assuming the problem is with Core Data, but I don't know where to begin to start debugging.

My data model has all of the necessary attributes; and managedObjectContext is shared with every view and passed to AddBookView from ContentView.

Here is my code

Thanks in advance for your suggestions!

I figured out the problem: Core Data doesn't work with Preview. You have to use the simulator to add books.
