It's incredibly easy to miss, I searched for almost an hour a few months back. Go to https://icloud.developer.apple.com/ and log in. Then, select your container on the left side. Afterwards, click on the small cogwheel in the development area (not production!). In this menu you'll find the option to "Deploy Schema to Production…".
