# addRecurrenceRule(_:)

Adds a recurrence rule to the recurrence rule array.

```
func addRecurrenceRule(_ rule: EKRecurrenceRule)
```

## Parameters

`rule`

The rule to be added to [`recurrenceRules`](/documentation/EventKit/EKCalendarItem/recurrenceRules).

## Discussion

The implementation only supports a single recurrence rule. Adding a recurrence rule replaces the single recurrence rule.
