CKRecord get value for key

I'm trying to get values for a user based on their username. I am able to get the correct user using:

class func getByUsername(username: String, callback: (records: [CKRecord]) -> ()){
    getSummary(NSPredicate(format: "Username == %@", username)){(records: [CKRecord]) -> Void in
        callback(records: records)
    }
}

class func getSummary(predicate: NSPredicate, callback: (records: [CKRecord]) -> ()){
    let query = CKQuery(recordType: "UserInfo", predicate: predicate)
    let queryOperation = CKQueryOperation(query: query)
    queryOperation.desiredKeys = ["ID"]

    var records = [CKRecord]()
    queryOperation.recordFetchedBlock = {record in records.append(record)}
    queryOperation.queryCompletionBlock = {_ in callback(records: records)}

    CKContainer.defaultContainer().publicCloudDatabase.addOperation(queryOperation)
}

and I am then able to get the correct record by calling:

getByUsername("Username"){(records: [CKRecord]) -> Void in
  var record: CKRecord = records[0]
}

and I can also get the correct ID by using

var id: String = record.recordID.recordName

So I know for a fact that I am fetching the correct record, but, when I try to get values from the record, such as the user's email, nil is returned:

var email: String = record.objectForKey("Email") as String

I've also tried:

record.valueForKey("Email")
record.valueForKeyPath("Email")

When I print record.allKeys(), I get an empty array, [], and when I print record.allTokens(), I get a return of nil

Am I not fetching a value from the record correctly, or do I have to query the database for every single value that I would like to get using the record ID? Based on what the documentation says:

A CKRecord object is a dictionary of key-value pairs that you use to fetch and save the data of your app.

I would assume that I do not have to query the database for every value that I would like to get, and that the values are automatically inserted into the CKRecord upon getting it from iCloud

When you leave out the line:

queryOperation.desiredKeys = ["ID"]

the query will return all the fields.

That you did not receive the ID field is probably because its a system field which can be accessed using

var ID = record.recordID.recordName
