# 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](../information-property-list/nscalendarsfullaccessusagedescription.md). If your app runs on iOS 17 or later and presents an [EKEventEditViewController](../../eventkitui/ekeventeditviewcontroller.md) 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.
