# userIdentities(forEmailAddresses:)

Fetches the user identities for the specified email addresses and returns them to an awaiting caller.

```
func userIdentities(forEmailAddresses emails: [String]) async throws -> [String : CKUserIdentity]
```

## Parameters

`emails`

The users’ email addresses.

## Return Value

A <doc://com.apple.documentation/documentation/Swift/Result> that contains either a dictionary of user identities, or an error that describes why CloudKit can’t discover the email addresses.

  In the successful case, the dictionary uses the email addresses you specify in   `emails`   as its keys. Only successfully discovered user identities are present in this dictionary.

## Discussion

Use this method to retrieve the identities of users who the current user knows. The users you’re searching for must meet the following criteria:

- The user has run the app.
- The user grants the [`userDiscoverability`](/documentation/CloudKit/CKContainer/ApplicationPermissions/userDiscoverability) permission for the container.

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