You must make the textView a subview of the UIImageView. However this is not possible to do in storyboards. The simplest way to accomplish what you want is to use a UIView as a container view, add the image view and textview as subviews, then you can snapshot the UIView using the function below. Your storyboard document outline should look like this

enter image description here

   func snapshot(view: UIView) -> UIImage? {
        UIGraphicsBeginImageContext(view.bounds.size)
        let savedFrame = view.frame;
        view.layer.render(in: UIGraphicsGetCurrentContext()!)
        let image = UIGraphicsGetImageFromCurrentImageContext();
        view.frame = savedFrame;
        UIGraphicsEndImageContext();
        return image
    }

So you should change your IBAction to the following. You must grab a reference to the UIView that contains both elements. I called it "containerView" in the below code.

@IBAction func SaveImage(_ sender: Any) {
        let image = snapshot(view: containerView)
        let imageRepresentation = UIImagePNGRepresentation(image!)
        let imageData = UIImage(data: imageRepresentation!)
        UIImageWriteToSavedPhotosAlbum(imageData!, nil, nil, nil)

        let alert = UIAlertController(title: "Completed", message: "Image has been saved!", preferredStyle: .alert)
        let action = UIAlertAction(title: "Ok", style: .default, handler: nil)
        alert.addAction(action)
        self.present(alert, animated: true, completion: nil)

}
