WidgetKit (iOS)

Timeline-driven glanceable UI for Home Screen, Lock Screen, StandBy, and Control Center. Widgets are SwiftUI views rendered by a separate extension process from snapshots your app supplies ahead of time — they are not live; you push data via timelines and reloads. Grounded in Apple's WidgetKit, App Intents, and SwiftUI.

• Related surfaces: real-time updating UI (delivery, timers, scores) → activitykit (Live Activities / Dynamic Island). The intent/entity layer → app-intents.
• KMP boundary: the widget extension links the shared framework directly, or reads data the main app wrote to a shared App Group container. Keep formatting/money logic in commonMain and hand the extension plain values; see kmp-ios-integration and kmp-money.
