Deleting a Row in the List with Data from Realm

I have created a very simple sample project just to make my point using RealmSwift..

// ContentView.swift //
import SwiftUI
import RealmSwift

struct ContentView: View {
	@StateObject var viewModel = ViewModel()
	
	var body: some View {
		NavigationView {
			VStack {
				Spacer()
				NavigationLink("Listing all meals") {
					ListView()
						.environmentObject(viewModel)
				}
				Spacer()
			}
		}
	}
}

// ListView.swift //
import SwiftUI
import RealmSwift

struct ListView: View {
	@EnvironmentObject var viewModel: ViewModel
	@State var meals = [MealDB]()
	
	var body: some View {
		List {
			ForEach(meals) { meal in
				HStack {
					Text("\(meal.title)")
						.padding(.leading, 6.0)
					Spacer()										
					Button {
						viewModel.model.delete(id: meal.id)
					} label: {
						Text("Delete")
					}
					.padding(.trailing, 6.0)
					.buttonStyle(.borderless)
				}
				.onDrag {
					return NSItemProvider()
				}
			}
			.onMove(perform: move(from:to:))
		}
		.onAppear {
			updateData()
		}
	}
	
	func updateData() {
		meals.removeAll()
		// data from Realm database
		for mealItem in viewModel.mealItems {// <<<<<<<<<<
			meals.append(mealItem)
		}
		meals.sort {
			(($0).place < (($1).place))
		}
	}
}

// ViewModel.swift //
import Foundation
import RealmSwift

class ViewModel: ObservableObject {
	@Published var model = MealStore()
	var mealItems: Results<MealDB> {
		model.items
	}
}

final class MealStore: ObservableObject {
	var config: Realm.Configuration
	
	init() {
		config = Realm.Configuration()
	}
	
	var realm: Realm {
		return try! Realm(configuration: config)
	}
	
	var items: Results<MealDB> {
		realm.objects(MealDB.self)
	}
}

// MealDB.swift //
import Foundation
import RealmSwift

class MealDB: Object, Identifiable {
	@objc dynamic var id = ""
	@objc dynamic var title = ""
	@objc dynamic var order = 0
	@objc dynamic var place = 0
	
	override class func primaryKey() -> String? {
		"id"
	}
}

ListView has a list of meals. Each row comes with a button that lets me delete the corresponding row. And the app will crash inside the updateData function. I have found out that the issue is the way how SwiftUI works and hangs on to the old set of data even after I tap the delete button. So a solution is to 'freeze up' the dataset. And the app won't crash when I tap the delete button.

for mealItem in viewModel.mealItems.freeze() {
   ...
}

Now, my question is... Are there reasons for not freezing up the dataset? If there is no downside, how come MongoDB just doesn't tell us to do it when we use access a dataset in Realm? Thanks.
