• Going / Not Going voting with live counts and destination history with attendance stats
• UIViewRepresentable wrapper around MKMapView with SwiftUI state bindings

learnings

• MapKit integration with SwiftUI via UIViewRepresentable
• Real-time data sync patterns with Firestore snapshot listeners
• iOS location permissions and CoreLocation best practices
• Bridging UIKit components into a SwiftUI-first architecture
