Using CoreData as dynamic Widget Intents in SwiftUI

I've followed along the Apple Developer Code-Along videos (https://developer.apple.com/news/?id=yv6so7ie) as well as looked at this repo with different Widget types (https://github.com/pawello2222/WidgetExamples) in search on how to populate a dynamic intent with items from Core Data.

My question is: How can I used the saved Core Data objects from the user to have them as "filters" or options in widget settings?

My Core Data model is called Favourite and it is a Class Definition CodeGen file.

I have added the Intent target to my project and can get it to appear in the Widget settings, but when I tap in to "Choose" the list is empty. However, in my Core Data there are 3 saved items.

I have tried doing simple things like print(CoreDM.shared.getAllFavourites()) to see if I am even retrieving them all, but not listing in the settings, but the console prints out:

<NextDeparturesIntent: 0x283490bd0> {
    favourite = <null>;
}

At this point I'm stuck on understanding on how I can get my Favourites visible and then usable. It seems everything else is hooked up and working or ready but the retrieval.

I have also tried re-adding into the Info.plist of the intent the IntentSupported of the intent's name: NextDeparturesIntentHandling:

but that had no success.

Core Data Model - Favourite - FavouritesCDModel

In my Core Data model I have more options but for this example:

• UUID
• beginName
• finishName

Widget Intent - NextDepartures.intentdefinition

This is what has been set up as followed by Apple's Code Along videos:

app-name-intent - IntentHandler.swift

import Intents

class IntentHandler: INExtension, NextDeparturesIntentHandling {
  let coreDM = CoreDataManager.shared

  func provideFavouriteOptionsCollection(
    for intent: NextDeparturesIntent,
    with completion: @escaping (INObjectCollection<FavouriteRoutes>?, Error?) -> Void
  ) {

    dump( coreDM.getAllFavourites() ) // <--- debug line

    let favouriteRoutes = coreDM.getAllFavourites().map {
      FavouriteRoutes(identifier: $0.uniqueId, display: $0.departingStopName!)
    }

    let collection = INObjectCollection(items: favouriteRoutes)
    completion(collection, nil)
  }

  override func handler(for intent: INIntent) -> Any {
    return self
  }
}

CoreDataManager

import CoreData

final class CoreDataManager {

  static let shared = CoreDataManager()
  private init() {}

  private let persistentContainer: NSPersistentContainer = {
    let container = NSPersistentContainer(name: "FavouritesCDModel")
    container.loadPersistentStores(completionHandler: { description, error in
      if let error = error as NSError? {
        fatalError("Core Data Store failed \(error.localizedDescription)")
      }
    })
    return container
  }()

  var managedObjectContext: NSManagedObjectContext {
    persistentContainer.viewContext
  }

  func getAllFavourites() -> [Favourite] {
    let fetchRequest: NSFetchRequest<Favourite> = Favourite.fetchRequest()
    do {
      return try managedObjectContext.fetch(fetchRequest)
    } catch {
      return []
    }
  }
}
