ios – Easy methods to ship e-mail message?

I’m utilizing this code to ship a e-mail message. However I do not see MFMailComposeViewController when will I name it.

import MessageUI

class Mail: UIViewController, MFMailComposeViewControllerDelegate {
    override func viewDidLoad() {
        tremendous.viewDidLoad()
    }
    func ship(title: String, deal with: [String], message: String, errorTitle: String, errorMessage: String) {
        if MFMailComposeViewController.canSendMail() {
            let mail = MFMailComposeViewController()
            mail.mailComposeDelegate = self
            mail.setSubject(title)
            mail.setToRecipients(deal with)
            mail.setMessageBody(message, isHTML: false)
            current(mail, animated: true, completion: nil)
        } else {
            let alert = UIAlertController(title: errorTitle, message: errorMessage, preferredStyle: .alert)
            alert.addAction(UIAlertAction(title: "OK", type: .default, handler: nil))
            self.current(alert, animated: true, completion: nil)
        }
    }
    func mailComposeController(_ controller: MFMailComposeViewController, didFinishWith outcome: MFMailComposeResult, error: Error?) {
        controller.dismiss(animated: true, completion: nil)
    }
}

Nothing occurs once I name the contactWithDeveloper() operate:

func contactWithDeveloper() { 
        Mail().ship(title: "title", deal with: ["[email protected]"], message: "message", errorTitle: "errorTitle", errorMessage: "errorMessage")
    }

However the Mail class is named. Easy methods to repair this?
