Hey Edward, if you can't figure out how to attack the challenge, your best bet is to rematch the videos.

You can also read some documentation to help you. Like this one for failable initializers : https://developer.apple.com/library/content/documentation/Swift/Conceptual/Swift_Programming_Language/Initialization.html#//apple_ref/doc/uid/TP40014097-CH18-ID224

Once you get some code starting (and if it's still not working), we can help you in a more precise way.
