I am trying to set up an app with send email option.

I have this code:

import MessageUI
import UIKit

class emailClass: UIViewContr         


        

Answer 1

Sending an Email is quit easy in Swift 5 you need to confirm and implement MFMailComposeViewControllerDelegate and check if we can send email on this device

Here is the tiny piece of code I was using for my task

import UIKit
import MessageUI

class ViewController: UIViewController, MFMailComposeViewControllerDelegate {

    override func viewDidLoad() {
        super.viewDidLoad()
    }

    //MARK: IBAction Method for Button click
    @IBAction func sendEmail(_ sender: Any) {
        //TODO:  You should chack if we can send email or not
        if MFMailComposeViewController.canSendMail() {
            let mail = MFMailComposeViewController()
            mail.mailComposeDelegate = self
            mail.setToRecipients(["you@yoursite.com"])
            mail.setSubject("Email Subject Here")
            mail.setMessageBody("
You're so awesome!
", isHTML: true)
            present(mail, animated: true)
        } else {
            print("Application is not able to send an email")
        }
    }

    //MARK: MFMail Compose ViewController Delegate method
    func mailComposeController(_ controller: MFMailComposeViewController, didFinishWith result: MFMailComposeResult, error: Error?) {
        controller.dismiss(animated: true)
    }
}

PS: Please don't forget you need to test this on real device
