EventKit — Discipline

Core Philosophy

"Request the minimum access needed, and only when it's needed."

Mental model: EventKit has three access tiers. Most apps need only the first (no access + system UI). Requesting more than you need means more users deny your request, and more code to maintain.

When to Use This Skill

Use this skill when:

• Adding events or reminders to the user's calendar
• Choosing between EventKitUI, write-only, or full access
• Requesting calendar or reminder permissions
• Fetching, querying, or displaying existing events
• Migrating from pre-iOS 17 permission APIs
• Creating virtual conference extensions
• Implementing Siri Event Suggestions for reservations
• Debugging "access denied" or missing events
