Please try below code for insert Image inside Email HTML Body.

Code works with Swift 4.0 & Swift 3.1

import MessageUI

class ViewController: UIViewController, MFMailComposeViewControllerDelegate{
    
    
    override func viewDidLoad() {
        super.viewDidLoad()
    }
     
    //MARK: - Send Email
    @IBAction func actionSendEmail(_ sender: Any) {
        
        if !MFMailComposeViewController.canSendMail() {
            print("Mail services are not available")
            return
        }
        let image = UIImage(named:"testImage") // Your Image
        let imageData = UIImagePNGRepresentation(image!) ?? nil
        let base64String = imageData?.base64EncodedString() ?? "" // Your String Image
        let strHtml = "<html><body><p>Header: Hello Test Email</p><p><b><img src='data:image/png;base64,\(String(describing: base64String) )'></b></p></body></html>"
        let composeVC = MFMailComposeViewController()
        composeVC.mailComposeDelegate = self
        // Configure the fields of the interface.
        composeVC.setToRecipients(["address@example.com"])
        composeVC.setSubject("Hello!")
        composeVC.setMessageBody(strHtml, isHTML: true)

        // Present the view controller modally.
        self.present(composeVC, animated: true, completion: nil)
    }
    
    //MARK:- MFMailCompose Delegate Methods
    func mailComposeController(_ controller: MFMailComposeViewController,
                               didFinishWith result: MFMailComposeResult, error: Error?) {
        // Dismiss the mail compose view controller.
        controller.dismiss(animated: true, completion: nil)
    }
    
}

This worked for me, make sure to use base64EncodedString and not base64EncodedData, also if you are using the multiline strings, you have to use String(format: args:) and use %@ and put the imageData in the args part without String(describing: ) — Sean Lintern, Mar 12 '18 at 15:12
