watchOS 5 version of Speedy Sloth

I'm beginning my watchOS 5 upgrade today and was disappointed to see that Apple has not provided any sample code for the new workout APIs. Did I miss something or has anyone update the Speedy Sloth sample code and put it on GitHub? If not, I may give it a try since my first attempt at updating my app has not gone smoothly and I'm not sure if me or the beta 🙂
