I'm pretty new to Swift and can't seem to find my mistake.

I have created a button and this is my code:

@IBAction func sendEmailTest(_ sender: Any) {
    UIApplication.shared.open(URL(string: "mailto:test@gmail.com")! as URL,
        options: [:], completionHandler: nil)
}

I want to open the mail program with this and I think this should be working. What am I doing wrong?

Here you go :

        import MessageUI


        if !MFMailComposeViewController.canSendMail() {
            print("Mail services are not available")
            return
        }
        let composeVC = MFMailComposeViewController()
        composeVC.mailComposeDelegate = self

        composeVC.setToRecipients(["test@gmail.com"])
        composeVC.setSubject("Report a Bug or Request a Feature")


        self.parent?.present(composeVC, animated: true, completion: nil)

  • While using `MFMailComposeViewController` is a fine suggestion, this answer doesn't actually solve the question being asked. If you read the question and the OP's comments, the problem is that the action isn't being called. So this answer does not actually solve the problem. – rmaddy Apr 30 '18 at 13:45

You've not put all of your code together there. What you're doing is opening a URL of mailto:test@gmail.com which isn't the correct way to do it. You should be using MFMailComposeViewController

First and foremost:

import MessageUI

And your code should be something similar to:

@IBAction func sendEmailTest(_ sender: Any) {

    if MFMailComposeViewController.canSendMail() {
    let composeVC = MFMailComposeViewController()
    composeVC.mailComposeDelegate = self

    composeVC.setToRecipients(["test@gmail.com"])
    composeVC.setSubject("Email Subject")
    composeVC.setMessageBody("", isHTML: false)

    self.present(composeVC, animated: true, completion: nil)

    } else {

        print("Cannot send mail")

    }
}

Also include a way to handle the code once a user has finished in the mail composer by including after the above method:

    func mailComposeController(_ controller: MFMailComposeViewController, didFinishWith result: MFMailComposeResult, error: Error?) {

    controller.dismiss(animated: true, completion: nil)

}

You can read more about MFMailComposeViewController on the Apple developer site here: https://developer.apple.com/documentation/messageui/mfmailcomposeviewcontroller

If indeed, you do want to open a URL, you should implement the following:

@IBAction func sendEmailTest(_ sender: Any) {
    if let url: NSURL = NSURL(string: "mailto:test@gmail.com") {
        UIApplication.shared.canOpenURL((url as NSURL) as URL)
    }
}

Make sure you run it on an actual device, not on simulator.

But MFMailComposeViewController should be the correct way of implementing it.

Hope this helps.
