Hey everyone I have been trying to make it runs but I face the same error again

DataController.swift

import Foundation
import CoreData

class DataController : ObservableObject {
    let container = NSPersistentContainer(name: "CoreDataProject")

    init() {
        container.loadPersistentStores { description , error in
            if let error = error {
                print("Core Data failed to load: \(error.localizedDescription)")
                return
            }

            self.container.viewContext.mergePolicy = NSMergePolicy.mergeByPropertyObjectTrump
        }
    }
}

ContentView

import SwiftUI
import CoreData

struct ContentView: View {

    @Environment(\.managedObjectContext) var moc
    @FetchRequest(sortDescriptors: [], predicate: nil) var wizards: FetchedResults<Wizard>

    var body: some View {
        VStack {
            List(wizards, id: \.self) { wizard in
                Text(wizard.name ?? "Unknown")
            }

            Button("Add") {
                let wizard = Wizard(context: moc)
                wizard.name = "Harry Potter"
            }

            Button("Save") {
                do {
                    try moc.save()
                } catch {
                    print(error.localizedDescription)
                }
            }
        }

    }
}

struct ContentView_Previews: PreviewProvider {
    static var previews: some View {
        ContentView()
    }
}

DataModel file name is CoreDataProject set Entity to "Wizard", codegen remains Class Definition, constraints is name

I have tried to delete the DataModel file and still failed, and I have tried previous question as reference and still no luck I have tried some methods from stack overflow, anyone has any idea how to fix it?

thanks in advance
