Attempting to load the view of a view controller while it is deallocating is not allowed and may result in undefined behavior

I am trying to implement a send mail code but I'm getting the following error : 

Attempting to load the view of a view controller while it is deallocating is not allowed and may result in undefined behavior

Here is my code piece:

    if MFMailComposeViewController.canSendMail() {
        let mail = MFMailComposeViewController()
        mail.mailComposeDelegate = self
        mail.setToRecipients(["@gmail.com"])            
        presentViewController(mail, animated: true, completion: nil)
    } else {
        // show failure alert
    }
Solution
