Hi guys,

First of all, I'm sorry if this is the wrong place to post this. I'm in the last steps of my task manager app: getting the tasks to sync between devices. However, I get the error "This NSPersistentStoreCoordinator has no persistent stores (unknown). It cannot perform a save operation." What does this error exactly mean? My container is initialised so it should have a persistent store, right? I've also enabled all the proper capabilities I'm pretty sure (eg, I've enabled CloudKit, created a container, enabled background fetch and remote notifications.) Here is the code for my data controller:

import CoreData
import Foundation

class DataController: ObservableObject {
    let container = NSPersistentCloudKitContainer(name: "TaskDataModel")
    
    init() {
        guard let description = container.persistentStoreDescriptions.first else {
            fatalError("Container descriptions not loaded")
        }
        description.setOption(true as NSNumber, forKey: NSPersistentHistoryTrackingKey)
        container.viewContext.mergePolicy = NSMergeByPropertyObjectTrumpMergePolicy
        container.viewContext.automaticallyMergesChangesFromParent = true
        container.loadPersistentStores { description, error in
            if let error = error {
                print("Core Data failed to load: \(error.localizedDescription)")
            }
        }
    }
}

Here is TaskManMain:

@main
struct TaskManApp: App {
    @StateObject private var dataController = DataController()
    
    var body: some Scene {
        WindowGroup {
            MainView()
                .environment(\.managedObjectContext, dataController.container.viewContext)
        }
    }
}

Thanks for any help!
