SwiftUI / CoreData / Master / Detail (with editing) / Xcode 11 - Beta 5

As promised, here is a link to sample SwiftUI program that uses CoreData. The current version compiles and runs on the GM release. It does not use the new @FetchRequest property wrapper because it does not suit all of my needs. I wrote a CoreDataDataSource class that does basically the same thing plus a lot more.
