Here how it looks for Swift 4:

import MessageUI

if MFMailComposeViewController.canSendMail() {
    let mail = MFMailComposeViewController()
    mail.mailComposeDelegate = self
    mail.setToRecipients(["test@test.test"])
    mail.setSubject("Bla")
    mail.setMessageBody("Blabla", isHTML: true)
    present(mail, animated: true, completion: nil)
} else {
    print("Cannot send mail")
    // give feedback to the user
}

func mailComposeController(_ controller: MFMailComposeViewController, didFinishWith result: MFMailComposeResult, error: Error?) {
        switch result.rawValue {
        case MFMailComposeResult.cancelled.rawValue:
            print("Cancelled")
        case MFMailComposeResult.saved.rawValue:
            print("Saved")
        case MFMailComposeResult.sent.rawValue:
            print("Sent")
        case MFMailComposeResult.failed.rawValue:
            print("Error: \(String(describing: error?.localizedDescription))")
        default:
            break
        }
        controller.dismiss(animated: true, completion: nil)
    }
