You need to create a new MFMailComposeViewController each time. Moving your mail declaration inside sendEmail works…

func sendEmail(body: String, subject: String) {
    if MFMailComposeViewController.canSendMail() {

       // Create a new MFMailComposeViewController…
       let mail = MFMailComposeViewController()

        mail.mailComposeDelegate = self

        mail.setSubject(subject)
        mail.setMessageBody("\(body)", isHTML: false)

        if let data = (body as NSString).data(using: String.Encoding.utf8.rawValue){
            //Attach File
            mail.addAttachmentData(data, mimeType: "text/plain", fileName: "data.txt")
        }

        present(mail, animated: true)
    } else {
        // show failure alert
    }
}

As to why…?
