🌍 SwiftUI Essentials – Landmarks App

A simple iOS app demonstrating SwiftUI basics, navigation, and state-driven interactivity using Apple’s tutorials:

🏗️ Project Structure

Part 1: 🧩 SwiftUI Essentials – Creating and Combining Views
- 🗺️ Built the LandmarkDetail view with:
  - 🗺️ MapView
  - 🖼️ CircleImage
  - 📐 Stacks (VStack, HStack) for layout
  - ⚡ Live previews in Xcode

Part 2: 📋 Building Lists and Navigation
- ➕ Created LandmarkRow to display a landmark’s image & name in a row
- 📜 Built LandmarkList using List to dynamically display all landmarks
- 🆔 Made Landmark conform to Identifiable for use in List
- 🔗 Used NavigationView + NavigationLink to enable navigation from the list to detail views
- ✅ Now users can browse a list of landmarks and tap to see details

Part 3: 🎛️ Handling User Input
- 📌 Introduced state management with the @State property wrapper
- ⭐ Added a Favorite Button (toggle with a star icon) to mark landmarks as favorites
- 🖱️ Connected button state to the landmark model, so UI updates automatically when toggled
- 📲 Updated LandmarkList to visually show favorite landmarks with a filled star
- 🎯 Reinforced SwiftUI’s declarative pattern: views react to changes in state automatically

Part 4: 🧩 Composing Complex Interfaces
- 🗂️ Integrated multiple views (LandmarkList, LandmarkDetail, FavoriteButton) into a more cohesive structure
- 🌐 Shared data across views by introducing ObservableObject and @EnvironmentObject for centralized state
- 📦 Modeled app data in ModelData to hold landmarks and allow consistent updates throughout the app
- 🔄 Ensured any change in data (like marking favorites) automatically propagates across all screens
- 📱 Built a more scalable app foundation, preparing for larger SwiftUI architectures

📍 Detail View: Shows map, circular image, and landmark info with declarative SwiftUI.
📋 Dynamic List View: Automatically generates rows from data.
🧭 Navigation Flow: Seamless transitions from list ➝ detail using SwiftUI navigation components.
⭐ Favorites: Mark and filter landmarks interactively with state-driven UI updates.
🌐 Shared State: Centralized ModelData ensures consistency across all parts of the app.
