# completionDate

The date on which the reminder was completed.

```
var completionDate: Date? { get set }
```

## Discussion

Setting this property to a date will set [`isCompleted`](/documentation/EventKit/EKReminder/isCompleted) to <doc://com.apple.documentation/documentation/Swift/true>; setting this property to `nil` will set `completed` to <doc://com.apple.documentation/documentation/Swift/false>.
