问题
I've googled over the internet, still can't find an official answer. I can see I can make build glance scenes, but those are "hidden" one swipe away from the user beneath actual watch face.
Are developers allowed to publish watch faces?
回答1:
No, it is not possible. In the Apple WatchKit forums, an Apple evangelist links to this thread for the FAQ on creating a custom watch face.

Technically, you could create an app that is a watch, but it wouldn't be a watch face.

I wanted to write my own watch face too - but for a hobby project, I don't think Apple allow time-centric apps for the Apple Watch on the App store at the moment. The App I've written works well as a watch face, but doesn't support complications/glances (which you'd get if it was an official watch face). I've blogged about how to write it here, with some code snippets in Swift: https://musingstudio.com/2016/08/04/how-to-write-a-watch-face-app-for-apple-watch/
