## What it does

The skill covers EventKit work in an iOS app: asking for access, creating and fetching events, reminders, recurrence rules, alarms, and the EventKitUI controllers. Sections come with Swift samples built on `EKEventStore`, `EKEvent`, `EKReminder`, `EKRecurrenceRule`, `EKEventEditViewController` and `EKCalendarChooser`. There is also a list of common mistakes and a review checklist.

Permissions are where this gets fiddly. On iOS 17 and later the legacy `requestAccess(to:)` call no longer prompts and throws instead, so the skill points you at the granular methods: `requestFullAccessToEvents()`, `requestWriteOnlyAccessToEvents()`, `requestFullAccessToReminders()`. Write-only access creates events but cannot fetch calendars or events — if you plan to look up or edit what you saved, you need full access. For iOS 10–16 the older request path still applies and belongs behind a version guard.

Your `Info.plist` needs the usage string that matches the chosen path: `NSCalendarsFullAccessUsageDescription`, `NSCalendarsWriteOnlyAccessUsageDescription` or `NSRemindersFullAccessUsageDescription`. The system event editor can create an event with no calendar access at all. Keep one `EKEventStore` instance and reuse it; objects from separate stores do not mix. Event queries run synchronously and are capped at a four-year span.

```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/dpearson2699/swift-ios-skills/tree/HEAD/skills/eventkit/SKILL.md

## When to use it
- request calendar and reminder access the iOS 17 way
- save a new event into a chosen calendar
- set up a repeating event with `EKRecurrenceRule`
- list writable calendars and pick one for saving
- present the system event editor with `EKEventEditViewController`

## Example prompts
- Add full calendar access and a Swift function that creates an event
- Create a reminder with a due date using `EKReminder` and save it
- Check this EventKit code for permission mistakes
