# NSCalendarsWriteOnlyAccessUsageDescription

A message that tells people why the app is requesting access to create calendar events.

## Discussion

If your app needs to read calendar events in addition to creating them, use [`NSCalendarsFullAccessUsageDescription`](/documentation/BundleResources/Information-Property-List/NSCalendarsFullAccessUsageDescription). If your app runs on iOS 17 or later and presents an <doc://com.apple.documentation/documentation/EventKitUI/EKEventEditViewController> to allow people to create calendar events, you don’t need to request calendar access.

> Important:
> This key is required if your app uses APIs that write to the person’s calendar data.
