Build calendar and reminder features for iOS.
Guides implementation and review of calendar and reminder features using EventKit and system editors.
When to use it
Use when implementing calendar events, reminders, recurrence, authorization, event editors, calendar selection, alarms, or change observation.
It changes how the agent implements and reviews calendar and reminder integrations in the project.
What you provide
The calendar and reminder integration uses the EventKit framework and a shared EKEventStore instance.
The app code follows iOS-specific availability rules: granular authorization on iOS 17+, guarded legacy APIs on iOS 10–16, and guarded typed change messages on iOS 26+.
