I am working on an app modeled after Paul's UltimatePortfolio. In the file AddRecipeView, I want to create a new recipe, with all its subordinate attributes and ingredients. This file/struct is called from ContentView.swift just as in UltimatePortfolio, as:

import SwiftUI

struct ContentView: View {
    @SceneStorage("selectedView") var selectedView: String?

    var body: some View {
        TabView(selection: $selectedView) {
            AddRecipeView()
                .tag(AddRecipeView.tag)
                .tabItem {
                    Image(systemName: "tray.and.arrow.down")
                    Text("Add Recipe")
                }
        }
    }
}

My Recipe and Ingredient classes are defined in Main.xcdatamodeld, with Recipe having an attribute of name, of type String. I have stripped out all the additional code for Recipe attributes and Ingredient and its attributes.

There is a an extension on Recipe for name, in the file Recipe-CoreDataHelpers.swift, as:

extension Recipe {

    var recipeName: String {
        name ?? ""                  // runtime error here!
    }
}

I get a compile error in AddRecipeView: ‘Cannot find “recipe” in scope’ on the line “addIngredient(to: recipe)“, when the line 'let recipe = Recipe()' is the first line of init(). And, if I move the line 'let recipe = Recipe()' above init(), I get a runtime error on the line 'name ?? "" ' in Recipe-CoreDataHelpers.swift. Apparently, something is wrong with 'recipe', but I can't figure out what. Can you please help with whatever I am missing? TIA, Bill

import SwiftUI

struct AddRecipeView: View {

    @Environment(\.managedObjectContext) var managedObjectContext
    @EnvironmentObject var dataController: DataController
    @Environment(\.presentationMode) var presentationMode

    @State private var name: String

    static let tag: String? = "AddRecipeView"

    init() {
        let recipe = Recipe()
        _name = State(wrappedValue: recipe.recipeName)
    }

    var body: some View {
        Form {
            Section(header: Text(“Basic settings”)) {
                TextField(“Recipe Name”, text: $name.onChange(update))
            }

            Button {
                addIngredient(to: recipe)                // compile error here!
            } label: {
                Label(“Add New Ingredient”, systemImage: “plus”)
            }
        }
        .navigationTitle(“Add Ingredient”)
        .onDisappear(perform: dataController.save)
    }

    func addIngredient(to recipe: Recipe) {
        withAnimation {
            let ingredient = Ingredient(context: managedObjectContext)
            ingredient.recipe = recipe
            dataController.save()
        }
    }

    func update() {
        recipe.name = name
    }

    func delete() {
        presentationMode.wrappedValue.dismiss()
    }
}
