A polished native iOS application crafted with Swift 5.9, SwiftUI, and the Composable Architecture (TCA) pattern. Core Data powers local persistence with CloudKit sync for seamless multi-device experiences. The app supports iOS 15 and later, adapts gracefully to iPhone, iPad, and Mac Catalyst, and includes a standalone WatchKit companion app. Internationalization covers English, Spanish, French, German, Portuguese, Hindi, and Arabic (with proper RTL layout). Dark mode, Dynamic Type up to accessibility sizes, VoiceOver labels on every interactive element, and full support for Switch Control and Voice Control ensure the app is usable by the widest possible audience. Payments via StoreKit 2 with family sharing and promotional offers. Analytics via Amplitude or Firebase (swap with one line). Push notifications via APNs with rich content extensions. Xcode Cloud CI config included. Full XCTest suite and snapshot tests with pointfreeco/swift-snapshot-testing.
