How can I add a list of ingredients to my recipe app?

To add a list of ingredients to your recipe app, you can leverage the App Intents framework to create a parameterized shortcuts action. This will allow users to interact with your app through Siri and the Shortcuts app, making it easier for them to add ingredients quickly and efficiently.

Here's a step-by-step guide based on the content from the WWDC sessions:

Define Your App Intent:

Create an app intent that includes a parameter for the list of ingredients. This will allow users to specify the ingredients they want to add.
Ensure the parameter summary is clear and readable, as it will help users understand what the intent does when they explore it in the Shortcuts app.

struct AddIngredientsIntent: AppIntent {
    static var title: LocalizedStringResource = "Add Ingredients"
    static var description = IntentDescription("Add a list of ingredients to your recipe app")

    @Parameter(title: "Ingredients")
    var ingredients: [String]

    func perform() async throws -> some IntentResult {
        // Your code to add ingredients to the recipe
        return .result()
    }
}

Integrate with Siri and Shortcuts:
- Once you have defined your app intent, it will automatically appear as an action in the Shortcuts app. Users can then create custom shortcuts that include adding ingredients to your recipe app.
```
struct RecipeApp: App {
    var body: some Scene {
        WindowGroup {
            ContentView()
        }
        .appIntents {
            AddIngredientsIntent()
        }
    }
}
```
Test and Validate:
- Test your app intent in the Shortcuts app to ensure it works as expected. You can create a shortcut that uses the "Add Ingredients" action and verify that it correctly adds the specified ingredients to your recipe app.
