Sending an email from your app with an image attached in Swift

I've tried a lot of tutorials on sending emails in your app but none of the ones I've seen show how to send an image with it. I'm recovering an image from .WriteToFile, This image is set to a UIImageView. How should I send an email with my picture?

You need to add an attachmentData to your mail, encoding your image in an NSData. This is an example that show you how to send an email with your image. I'm suppose that you have a UIViewController where you can put the function sendMail.

import MessageUI
class MyViewController: UIViewController, MFMailComposeViewControllerDelegate
{
  // .... your stuff

  func sendMail(imageView: UIImageView) {
    if MFMailComposeViewController.canSendMail() {
      let mail = MFMailComposeViewController()
      mail.mailComposeDelegate = self;
      mail.setCcRecipients(["yyyy@xxx.com"])
      mail.setSubject("Your messagge")
      mail.setMessageBody("Message body", isHTML: false)
      let imageData: NSData = UIImagePNGRepresentation(imageView.image)!
      mail.addAttachmentData(imageData, mimeType: "image/png", fileName: "imageName.png")
      self.presentViewController(mail, animated: true, completion: nil)
    }
  } 

}

In order to dismiss the VC, include the following method in your ViewController:

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

The documentation for this method is reported in MFMailComposeViewControllerDelegate.
