# fetchShareParticipant(withEmailAddress:completionHandler:)

Fetches the share participant with the specified email address.

```
func fetchShareParticipant(withEmailAddress emailAddress: String, completionHandler: @escaping @Sendable (CKShare.Participant?, (any Error)?) -> Void)
```

## Parameters

`emailAddress`

The share participant’s email address.

`completionHandler`

The handler to execute with the fetch results.

## Discussion

The closure doesn’t return a value and takes the following parameters:

- The share participant, or `nil` if CloudKit can’t find the participant.
- An error if a problem occurs, or `nil` if CloudKit successfully retrieves the participant.

CloudKit can translate any valid email address into a share participant.  If the email address doesn’t correspond to a known iCloud account, then at share-accept-time, CloudKit offers the accepting participant a vetting process. The accepting participant uses this vetting process to link the email address to an iCloud account.

This method searches for the share participant asynchronously and with a low priority. If you want the task to execute with a higher priority, create an instance of [`CKFetchShareParticipantsOperation`](/documentation/CloudKit/CKFetchShareParticipantsOperation) and configure it to use the necessary priority.
