您可以使用NSUserName()功能：

var username = NSUserName()!

let fullUserName = NSFullUserName()

Answer 3

以下对我有用。它是从 this post 复制的。

CKContainer.default().requestApplicationPermission(.userDiscoverability) { (status, error) in
    CKContainer.default().fetchUserRecordID { (record, error) in
        CKContainer.default().discoverUserIdentity(withUserRecordID: record!, completionHandler: { (userID, error) in
            let fullName = (userID?.nameComponents?.givenName)! + " " + (userID?.nameComponents?.familyName)!
        })
    }
}
