The users’ email addresses.

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 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 and configure it to use the necessary priority.
