Variable overriding itself when adding to a list

This is yet another expansion of my TextField and function questions.

The code for my Lunch Card app is pretty much set in stone, except for a little bug with a variable. This bug happens when you create a new card. Here's the code for both CardsView and AddView.

CardView:

import SwiftUI
struct Card: Identifiable {
    let id = UUID()
    let title: String
}
struct CardsView: View {
    @StateObject var cardsInfo = CardsInfo()
    @StateObject var sheetInfo = SheetInfo()
    @State private var editMode = EditMode.inactive
    
    var body: some View {
        NavigationView {
            List {
                ForEach(cardsInfo.cards) { cards in
                    NavigationLink(destination: CardFullView(cname: cardsInfo.newCard.cname, name: cardsInfo.newCard.name, id: cardsInfo.newCard.id)) {
                        CardRow(cname: cardsInfo.newCard.cname, name: cardsInfo.newCard.name, id: cardsInfo.newCard.id)
                    }
                }
                .onDelete(perform: onDelete)
                .onMove(perform: onMove)
            }.listStyle(PlainListStyle())
            .navigationTitle("Cards")
            .toolbar {
                ToolbarItem(placement: .navigationBarLeading) {
                    EditButton()
                }
                ToolbarItem(placement: .navigationBarTrailing) {
                    Button(action: {
                        self.sheetInfo.showSheetView.toggle()
                    }) {
                        Image(systemName: "plus")
                    }
                }
            }
            .environment(\.editMode, $editMode)
            .sheet(isPresented: $sheetInfo.showSheetView) {
                AddView(cardsInfo: cardsInfo, sheetInfo: sheetInfo)
            }
        }
    }
    
    private func onDelete(offsets: IndexSet) {
        cardsInfo.cards.remove(atOffsets: offsets)
    }
    private func onMove(source: IndexSet, destination: Int) {
        cardsInfo.cards.move(fromOffsets: source, toOffset: destination)
    }
}

AddView:

Code Block 
//
//  AddView.swift
//  Lunch Card (iOS)

//
import SwiftUI
struct AddView: View {
    @ObservedObject var cardsInfo: CardsInfo
    @ObservedObject var sheetInfo: SheetInfo
    var body: some View {
        NavigationView {
            VStack {
                CardView(name: cardsInfo.newCard.name, id: cardsInfo.newCard.id)
                TextField("Name", text: $cardsInfo.newCard.name)
                    .textFieldStyle(RoundedBorderTextFieldStyle())
                    .shadow(radius: 10)
                TextField("ID", text: $cardsInfo.newCard.id)
                    .textFieldStyle(RoundedBorderTextFieldStyle())
                    .keyboardType(.numberPad)
                    .shadow(radius: 10)
                TextField("Card Name", text: $cardsInfo.newCard.cname)
                    .textFieldStyle(RoundedBorderTextFieldStyle())
                    .shadow(radius: 10)
                Button(action: {
                    cardsInfo.add()
                    sheetInfo.showSheetView = false
                }) {
                    Text("Create")
                        .bold()
                }
                .disabled(self.cardsInfo.newCard.name.isEmpty    self.cardsInfo.newCard.id.isEmpty    self.cardsInfo.newCard.cname.isEmpty)
                .foregroundColor(.white)
                .padding()
                .padding(.horizontal, 100)
                .background(Color.accentColor)
                .cornerRadius(10)
            }.padding()
            .navigationTitle(cardsInfo.newCard.cname)
            .navigationBarTitleDisplayMode(.inline)
        }
    }
}

AddView shows as a sheet.

When looking, you can see that cardsInfo.newCard is being used to signify - if not obvious - a new card. But, the bug here is that when you add multiple cards, the previous cards are being overridden.

A solution I'm thinking of is adding the already-added cards into some kind of database or text file, but (1) I have literally no idea how I would approach that, and (2) that would probably mean rewriting about 3/4 of the existing code, which is a path that I am trying to avoid.
