Answer 1

In the view controller from where you want your mail-app to open on the tap.

• At the top of the file do, import MessageUI.

• Put this function inside your Controller.

  func showMailComposer(){
  
    guard MFMailComposeViewController.canSendMail() else {
         return
    }
    let composer = MFMailComposeViewController()
    composer.mailComposeDelegate = self
    composer.setToRecipients(["abc@gmail.com"]) // email id of the recipient
    composer.setSubject("testing!!!")
    composer.setMessageBody("this is a test mail.", isHTML: false)
    present(composer, animated: true, completion: nil)
   }
  

• Extend your View Controller and conform to the MFMailComposeViewControllerDelegate.

• Put this method and handle the failure, sending of your mails.

  func mailComposeController(_ controller: MFMailComposeViewController, didFinishWith result: MFMailComposeResult, error: Error?) {
    if let _ = error {
        controller.dismiss(animated: true, completion: nil)
        return
    }
    controller.dismiss(animated: true, completion: nil)
  }
