swiftui delete core data row

I want to use core data to store my data. Also, I want to delete the data (row) when I want. I have referenced the site below. https://blckbirds.com/post/core-data-and-swiftui/

The data can be added well, but I want to delete the data without using the List and ForEach{}.onDelete().

However, as a result of my search, I couldn't find a way to delete a row of core data other than using ForEach's .onDelete().

Is there a way to delete specific data (Row) without using list, ForEach onDelete??

import SwiftUI
import CoreData

struct ContentView: View {
    @Environment(\.managedObjectContext) private var context
    @FetchRequest(
        sortDescriptors: [NSSortDescriptor(keyPath: \Order.timestamp, ascending: true)],
        animation: .default)
    private var orders: FetchedResults<Order>

//.....your code....

for order in orders {
  if order.name == «KuKu” {//here is your condition 
  self.deleteSelectedOrder(selectedOrder: order)
  }
}
func deleteSelectedOrder(selectedOrder: Order){
  context.delete(selectedOrder as! NSManagedObject)
            do {
                try context.save()
            } catch {
               
                let nsError = error as NSError
                fatalError("Unresolved error \(nsError), \(nsError.userInfo)")
            }
}
