Answer 1

This is how I have composed my email with attached PDF file document.

Just to test this example you need to drag and drop a sample PDF named "All_about_tax.pdf"

@IBAction func sendEmail(sender: UIButton)
    {
        //Check to see the device can send email.
        if( MFMailComposeViewController.canSendMail() )
        {
            print("Can send email.")

            let mailComposer = MFMailComposeViewController()
            mailComposer.mailComposeDelegate = self

            //Set to recipients
            mailComposer.setToRecipients(["your email id here"])

            //Set the subject
            mailComposer.setSubject("Tax info document pdf")

            //set mail body
            mailComposer.setMessageBody("This is what they sound like.", isHTML: true)

            if let filePath = NSBundle.mainBundle().pathForResource("All_about_tax", ofType: "pdf")
            {
                print("File path loaded.")

                if let fileData = NSData(contentsOfFile: filePath)
                {
                    print("File data loaded.")
                    mailComposer.addAttachmentData(fileData, mimeType: "application/pdf", fileName: "All_about_tax.pdf")

                }
            }

            //this will compose and present mail to user
            self.presentViewController(mailComposer, animated: true, completion: nil)
        }
        else
        {
            print("email is not supported")
        }
    }



    func mailComposeController(controller: MFMailComposeViewController, didFinishWithResult result: MFMailComposeResult, error: NSError?)
    {
        self.dismissViewControllerAnimated(true, completion: nil)
    }
