I don't see anywhere in your source code where you have included the file containing the Swift_SendmailTransport class. You can either download the source file for the class and include it in your code, or you can install the package via Composer and use an autoloader. The teacher's notes direct you to the SwiftMailer website: http://swiftmailer.org/. That should help get you started.
