Q:

Adding additional string to message body (swift)

I got my email working fine.  The only thing i need to do is add an additional string to my message body.  For example, I want to add Name: and textfield to my message body. Something like this. 
Name:  John Smith
Phone: 566-654-6577
Email:  Smith@smith.com
Right now, the message body only show the following. 
John Smith
566-654-6577
Smith@smith.com
import UIKit
import MessageUI

class EmailTableViewController: UITableViewController, MFMailComposeViewControllerDelegate, UITextFieldDelegate {

    @IBOutlet weak var name: UITextField!

    @IBOutlet weak var phone: UITextField!

    @IBOutlet weak var email: UITextField!

    func appendTextFromTextField(string: String, textField: UITextField) -> String {
        return string + textField.text + "\n \n"
    }

    @IBAction func SendEmailButton(sender: AnyObject) {

        var fields: [UITextField] = [name, phone, email]
        var messageBody = ""

        for f in fields {
            messageBody = appendTextFromTextField(messageBody, textField: f)
        }

        var emailTitle = "Interface Information"
        var toRecipents = [""]
        var mc: MFMailComposeViewController = MFMailComposeViewController()
        mc.mailComposeDelegate = self
        mc.setSubject(emailTitle)
        mc.setMessageBody(messageBody, isHTML: false)
        mc.setToRecipients(toRecipents)
        self.presentViewController(mc, animated: true, completion: nil)

    }

    func mailComposeController(controller:MFMailComposeViewController, didFinishWithResult result:MFMailComposeResult, error:NSError) {
        switch result.value {
        case MFMailComposeResultCancelled.value:
            println("Mail cancelled")
        case MFMailComposeResultSaved.value:
            println("Mail saved")
        case MFMailComposeResultSent.value:
            println("Mail sent")
        case MFMailComposeResultFailed.value:
            println("Mail sent failure: %@", [error.localizedDescription])
        default:
            break
        }
        self.dismissViewControllerAnimated(true, completion: nil)

    }

    override func viewDidLoad() {

        super.viewDidLoad()

    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()

    }

}

A:

Remove the for loop and try replacing your method with this one:
@IBAction func sendEmailButton(sender: UIButton) {
        var messageBody = "Name:\(name.text)\nPhone:\(phone.text)\nEmail:\(email.text) "
        var emailTitle = "Interface Information"
        var toRecipents = [""]
        var mc: MFMailComposeViewController = MFMailComposeViewController()
        mc.mailComposeDelegate = self
        mc.setSubject(emailTitle)
        mc.setMessageBody(messageBody, isHTML: false)
        mc.setToRecipients(toRecipents)
        self.presentViewController(mc, animated: true, completion: nil)
    }
