Build guide

1. 01Project Scaffolding & Data Model Architecture

   Initialize a multi-platform SwiftUI project in Xcode and define the core SwiftData models for Recipes, Ingredients, Steps, and MealPlans.

   Create a new multiplatform SwiftUI app structure supporting iOS, iPadOS, and macOS. Set up SwiftData models for Recipe (title, sourceURL, prepTime, cookTime, servings, notes), Ingredient (name, amount, unit, category), InstructionStep (stepNumber, text), and MealPlanItem (date, mealType, recipeID). Ensure all models conform to PersistentModel with appropriate relationships. Write robust unit tests for fraction scaling logic on ingredients, ensuring qualitative units like 'pinch' or 'to taste' do not break multiplier arithmetic when scaling servings up or down.

2. 02Recipe URL Scraper & Parsing Engine

   Implement a web scraper that fetches recipe page HTML, extracts JSON-LD recipe schema data, and falls back to an AI API parser for unstructured pages.

   Build a Swift service class called `RecipeParserService` that takes a URL string, fetches the page HTML using URLSession, and parses it. First, look for `<script type="application/ld+json">` blocks containing schema.org/Recipe data to extract title, ingredients, and instructions reliably. If JSON-LD is missing or fails, extract the raw article text and send it to the Gemini API using structured JSON output mode to extract the exact same recipe schema. Return a fully populated Recipe model object ready for local storage insertion.

3. 03Recipe Library & Detailed SwiftUI Views

   Build the main recipe list interface, card views, search filtering, and a clean reading view with unit conversion toggles.

   Design and implement the SwiftUI views for the recipe library. Create a responsive Grid/List layout with search filtering by title and ingredient. Build a dedicated RecipeDetailView featuring an ingredient scaling stepper (dynamically recalculating amounts from base servings), a unit conversion toggle button (switching between Metric grams/ml and Imperial ounces/cups on the fly), and a clean instruction checklist view where completed steps can be ticked off.

4. 04Guided Hands-Free Cooking & Timer Integration

   Create an immersive cooking mode view with large text, voice command placeholders, and interactive timer chips parsed from step text.

   Build a full-screen SwiftUI `CookingModeView` optimized for tablets and phones in the kitchen. The view should present one step at a time in large, legible typography with prominent Next/Previous controls. Implement a regex parser inside instruction text that automatically detects time durations (e.g., 'simmer for 20 minutes', 'bake for 15 mins') and renders interactive countdown timer pills that users can tap to start live system notifications and Live Activities.

5. 05Meal Planner & Automated Shopping List Aggregator

   Develop a weekly calendar grid for meal planning and an aggregator engine that compiles and deduplicates shopping list items.

   Implement a weekly calendar grid view (`MealPlannerView`) allowing users to assign recipes to breakfast, lunch, or dinner slots for any day of the week. Build an accompanying `ShoppingListService` that aggregates all ingredients from recipes scheduled in the current week's meal plan, intelligently deduplicates identical ingredients (e.g., combining '2 cloves garlic' and '3 cloves garlic' into '5 cloves garlic'), groups them by supermarket category (Produce, Pantry, Dairy), and presents them in a checkable shopping list view.

6. 06CloudKit Sync & Household Sharing

   Configure CloudKit container entitlements and background sync so recipes and meal plans sync seamlessly across user devices and shared household accounts.

   Configure SwiftData to use a CloudKit container sharing setup for multi-device synchronization. Implement a `HouseholdSharingService` that allows users to share a CloudKit share record via Apple's standard UIActivityViewController or ShareSheet. Handle incoming share invitations so that invited family members can read, edit, and add recipes and meal plans to the shared household database in real time with proper conflict resolution.

7. 07StoreKit 2 Monetization & Paywall

   Integrate StoreKit 2 subscriptions and lifetime purchases to gate unlimited recipe storage and household features behind a paywall.

   Implement an in-app purchase manager using StoreKit 2 (`StoreKitManager`) supporting an annual subscription ($24.99/yr) and a lifetime buyout ($59.99). Build a clean SwiftUI PaywallView that triggers when free users attempt to save their 16th recipe or create a household. Handle purchase verification, trial periods, restoration of purchases, and expose an `@Observable` entitlement status across the app to unlock Pro features.
