Update for app delegate adaptor about swiftdb HOT 4 CLOSED

@malhal thank you for raising the issue! UIApplicationDelegateAdaptor will not help here because with/without it there is no direct access to the Environment of the underlying UIHostingController. The typical boilerplate that sets up persistentContainer on the AppDelegate is just that - boilerplate. There's no delegate property on UIApplicationDelegate that exposes an NSPersistentContainer - so it really doesn't matter where it's stored :)

Closing this issue, please feel free to reopen it if you have any further concerns.

Give this a try:

import SwiftUI
import CoreData

@main
struct MasterDetailApp: App {
    
    @UIApplicationDelegateAdaptor var appDelegate : AppDelegate
    
    var body: some Scene {
        WindowGroup {
            ContentView().environment(\.managedObjectContext, appDelegate.persistentContainer.viewContext)
        }
    }
    
}

The persistentContainer needs to be in the app delegate so the viewContext can be saved when the app suspends.

@malhal the AppDelegate is not a part of the SwiftUI or UIKit module. There is no way for me to reference it within SwiftDB.
