# isCompleted

A Boolean value determining whether or not the reminder is marked completed.

```
var isCompleted: Bool { get set }
```

## Discussion

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

### Special Considerations

If the reminder was completed using a different client, you may encounter the case where this property is <doc://com.apple.documentation/documentation/Swift/true>, but `completionDate` is `nil`.
