Sending an email in SwiftUI can be done using the MessageUI framework. The MessageUI framework provides a simple and easy-to-use interface for sending emails in iOS apps. Here’s an example of how to send an email in SwiftUI:

import Foundation
import MessageUI

class EmailController: NSObject, MFMailComposeViewControllerDelegate {
    public static let shared = EmailController()
    private override init() { }
    
    func sendEmail(subject:String, body:String, to:String){
        // Check if the device is able to send emails
        if !MFMailComposeViewController.canSendMail() {
           print("This device cannot send emails.")
           return
        }
        // Create the email composer
        let mailComposer = MFMailComposeViewController()
        mailComposer.mailComposeDelegate = self
        mailComposer.setToRecipients([to])
        mailComposer.setSubject(subject)
        mailComposer.setMessageBody(body, isHTML: false)
        EmailController.getRootViewController()?.present(mailComposer, animated: true, completion: nil)
    }
    
    func mailComposeController(_ controller: MFMailComposeViewController, didFinishWith result: MFMailComposeResult, error: Error?) {
        EmailController.getRootViewController()?.dismiss(animated: true, completion: nil)
    }
    
    static func getRootViewController() -> UIViewController? {   
        // In SwiftUI 2.0
        UIApplication.shared.windows.first?.rootViewController
    }
}

Now add a button action to send the email:

import SwiftUI

Button(action: {
   EmailController.shared.sendEmail(subject: "Hello", body: "Hello From ishtiz.com", to: "recipient@example.com")
 }) {
     Text("Send Email")
 }
