Send email with attachment using Gmail API

Question

I'm trying to send and email with attachment using Gmail API. My progress so far:

class func generateRawString(to: NSMutableArray, subject: String, body: String) -> String {

        let dateFormatter:NSDateFormatter = NSDateFormatter()
        dateFormatter.dateFormat = "EEE, dd MMM yyyy HH:mm:ss Z"; //RFC2822-Format
        let todayString:String = dateFormatter.stringFromDate(NSDate())

        let userDefaults = NSUserDefaults.standardUserDefaults()
        let mailLoggedUser = userDefaults.objectForKey("email") as! String
        let username = userDefaults.objectForKey("userName") as! String
        let rawMessage = "" +
            "Date: \(todayString)\r\n" +
            "From: \(username)<\(mailLoggedUser)>\r\n" +
            "To: \(self.generateRecipientsToMail(to))\r\n" +
            "Subject: \(subject)\r\n\r\n" +
            body
        return GTLEncodeWebSafeBase64(rawMessage.dataUsingEncoding(NSUTF8StringEncoding))
    }

class func sendEmail(to: NSMutableArray, isRecursive:Bool, subject: String, body: String, threadId: String, attachmentBase64: String, completionBlock:(Bool, AnyObject?)->()) {

        let gtlMessage = GTLGmailMessage()
        gtlMessage.raw = self.generateRawString(to, subject: subject, body: body)

        let encodeDataString = attachmentBase64.dataUsingEncoding(NSUTF8StringEncoding)
        let upParam = GTLUploadParameters(data: encodeDataString!, MIMEType: "message/rfc822")

        if threadId.length > 0 {
            gtlMessage.threadId = threadId
        }

        let appd = UIApplication.sharedApplication().delegate as! AppDelegate
        let query = GTLQueryGmail.queryForUsersMessagesSendWithUploadParameters(upParam)
        query.message = gtlMessage

        appd.service.executeQuery(query, completionHandler: { (ticket, response, error) -> Void in
            print("ticket ==> \(ticket)")
            print("response ==>\(response)")
            print("error ==> \(error)")
        })
    }

Response log

GTLGmailMessage 0x7fbb7e077a30: {id:"15264d6492cedfa5" threadId:"15264d6492cedfa5" labelIds:[1]}

I can not find a way to make it work and even tried to help using: source 1 source 2

You could just mimic the first source :) Get the file data in base64 and add it to the `rawMessage` in your code. Then just send the raw message as you do now WITHOUT encoding the entire message (since your content type is `message/rfc822`) — Tholle, Jan 22 '16 at 00:35
@ Tholle I already tried, but the email is going as plain text — jose920405, Jan 26 '16 at 21:00
