Send mail with file attachment

Question

I search solution to send a mail with attachment. I have this code but the file is not attached...

if let url = URL(string: "mailto:\(email)?subject=report&body=see_attachment&attachment=/Users/myname/Desktop/report.txt") {
    NSWorkspace.shared().open(url)
}

I have see it maybe work with MessageUI, but I can't import this framework I don't know why. I get this error message : No such module 'MessageUI' I checked in General > Linked Frameworks and Libraries, but there are not MessageUI...

Anyone have a solution to add file in mail? Thanks

Answer 1

It seems that attachment in mailto: URLs are not supported on macOS (not always at least...details seems sketchy dependent on where you look on the internet :))

What you can use instead I found out from this blog post , is an instance of NSSharingService documented here

Here is an example demonstrating how to use it.

And in your case you could do something like:

let email = "your email here"
let path = "/Users/myname/Desktop/report.txt"
let fileURL = URL(fileURLWithPath: path)

let sharingService = NSSharingService(named: NSSharingServiceNameComposeEmail)
sharingService?.recipients = [email] //could be more than one
sharingService?.subject = "subject"
let items: [Any] = ["see attachment", fileURL] //the interesting part, here you add body text as well as URL for the document you'd like to share

sharingService?.perform(withItems: items)

Update

So @Spire mentioned in a comment below that this won't attach a file.

It seems there is a gotcha to be aware of.

For this to work you need to look into your App Capabilities.

You can either:

• disable App Sandbox
• enable read access for the folders from where you would like to fetch content.

I've attached a couple of screenshots.

Here is how this looks if I have disabled App Sandbox under Capabilities

And here is an image where I have enabled App Sandbox and allowed my app to read content in my Downloads folder

If I do the above, I can access my file called document.txt , located in my Downloads folder, using this URL

let path = "/Users/thatsme/Downloads/document.txt"
let fileURL = URL(fileURLWithPath: path)

And attach that to a mail

Hope that helps you.

import MessageUI
class ViewController: UIViewController,MFMailComposeViewControllerDelegate {

func sendMail() {
  if( MFMailComposeViewController.canSendMail()){
        print("Can send email.")

        let mailComposer = MFMailComposeViewController()
        mailComposer.mailComposeDelegate = self

        //Set to recipients
        mailComposer.setToRecipients(["yakupad@yandex.com"])

        //Set the subject
        mailComposer.setSubject("email with document pdf")

        //set mail body
        mailComposer.setMessageBody("This is what they sound like.", isHTML: true)
        let pathPDF = "\(NSTemporaryDirectory())contract.pdf"
            if let fileData = NSData(contentsOfFile: pathPDF) 
            {
                print("File data loaded.")
                mailComposer.addAttachmentData(fileData as Data, mimeType: "application/pdf", fileName: "contract.pdf")
            }

        //this will compose and present mail to user
        self.present(mailComposer, animated: true, completion: nil)
    }
    else
    {
        print("email is not supported")
    }

  func mailComposeController(_ didFinishWithcontroller: MFMailComposeViewController, didFinishWith result: MFMailComposeResult, error: Error?)
  {
    self.dismiss(animated: true, completion: nil)
  }
}

First of all you should import import MessageUI . For this add framework to the project.

Example:

After investigate MFMailComposeViewControllerDelegate for knowing when you end sending email.

Example of the creating of the email:

if( MFMailComposeViewController.canSendMail() ) {
        println("Can send email.")

        let mailComposer = MFMailComposeViewController()
        mailComposer.mailComposeDelegate = self

        //Set the subject and message of the email
        mailComposer.setSubject("Have you heard a swift?")
        mailComposer.setMessageBody("This is what they sound like.", isHTML: false)

        if let filePath = NSBundle.mainBundle().pathForResource("swifts", ofType: "wav") {
            println("File path loaded.")

            if let fileData = NSData(contentsOfFile: filePath) {
                println("File data loaded.")
                mailComposer.addAttachmentData(fileData, mimeType: "audio/wav", fileName: "swifts")
            }
        }
        self.presentViewController(mailComposer, animated: true, completion: nil)
    }
