How do I get emailAddress to discoverUserIdentity?

Question

Currently I do:

    if #available(iOS 10.0, *) {

        CKContainer.default().discoverUserIdentity(withEmailAddress: "barteks****@icloud.com") { identity, error in

            print(error?.localizedDescription)
            print(identity)
        }
    }

the result is:

nil
nil

I am pretty sure that following address exists, because it is mine. Why it prints nil?

I follow this tutorial and got stuck with Look up via phone chapter.

What do I try to do?

I would like to share some records with other user. But first I need to somehow determine that user. Is it correct?

Maybe you checked yet but... Is your device/simulator logged on iCloud? — Adolfo, Mar 06 '17 at 15:22
Because Apple broke this in the iOS 10.3 release. See my post here: http://stackoverflow.com/questions/43130466/discoverallidentities-discoveruseridentity-returning-nil-for-ckuseridentity-lo — Wizkid, Apr 07 '17 at 20:26

Request permission first:

[[CKContainer defaultContainer] requestApplicationPermission:CKApplicationPermissionUserDiscoverability
             completionHandler:^(CKApplicationPermissionStatus applicationPermissionStatus, NSError *error) {
                       // check(applicationPermissionStatus == CKApplicationPermissionStatusGranted)
             });}
