How to automatically attach last photo taken to Mail?

Question

I'm making an app that sends an email with the last photo taken (screenshot) attached, I'm stuck at adding the last photo taken.

I tried searching everywhere and only found the fetch code but didn't understand it and didn't know how to implement it in my code

func takeScreenshot(){

        UIGraphicsBeginImageContextWithOptions(view.bounds.size, false, UIScreen.main.scale)
        view.layer.render(in: UIGraphicsGetCurrentContext()!)
        let image = UIGraphicsGetImageFromCurrentImageContext()
        UIGraphicsEndImageContext()

        UIImageWriteToSavedPhotosAlbum(image!, nil, nil, nil)

    }

    func sendMail(){
        let mail = MFMailComposeViewController()
        if MFMailComposeViewController.canSendMail(){
            mail.mailComposeDelegate = self
            mail.setToRecipients(["test@test.com"])
            mail.setSubject("Test mail subject")
            mail.setMessageBody("Test mail body", isHTML: false)
        } else {
            self.mailFailedToSent()
        }

    }

    func mailFailedToSent(){
        let mailFailedToSentAllert = UIAlertView(title: "Could not send mail", message: "You need to add Mail account in Settings > Passwords & Accounts > Add Account", delegate: self, cancelButtonTitle: "OK")
        mailFailedToSentAllert.show()
    }

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

    @IBAction func reportButtonAction(_ sender: Any) {

        takeScreenshot()
        sendMail()
    }

EDIT: i tried what @user3344236 suggested and i got error at return image!:

 func getImage(asset: PHAsset) -> UIImage{
    let fetchOptions = PHFetchOptions()
    fetchOptions.sortDescriptors = [NSSortDescriptor(key: "creationDate", ascending: false)]
    fetchOptions.fetchLimit = 1

    let fetchResult = PHAsset.fetchAssets(with: .image, options: fetchOptions)

    if (fetchResult.firstObject != nil) {

        var lastAsset: PHAsset = fetchResult.lastObject as! PHAsset
        var image = UIImage()
        PHImageManager.default().requestImage(for: lastAsset, targetSize: CGSize(width: 100, height: 100) , contentMode: .aspectFill, options: PHImageRequestOptions(), resultHandler: { (result, info) -> Void in

            image = result!

        })
        return image!  //Cannot force unwrap value of non-optional type 'UIImage'
    }

}

This is about inserting an image in the body, not attachment and not how to automatically get the last photo and attach it — Jack Reacher, Jun 20 '19 at 13:22
Use Photos Framework , sort by creationDate ascending false, the feched array object [0] is what you need. See https://stackoverflow.com/questions/29009621/url-of-image-after-uiimagewritetosavedphotosalbum-in-swift — ares777, Jun 20 '19 at 13:51
