Developer Steve Troughton-Smith used SpriteKit to create his own Apple Watch face:

This is an end-around, bypassing Apple’s lack of support for 3rd party watch faces. Scroll through the Twitter thread, check out all the faces. I hope Apple allows this bit of a market to evolve, eventually adding official support.
One concern about all this is the fear that Apple would be liable for watch face copyright infringement. Some say that that’s the reason Apple does not allow 3rd party watch faces. Does this eliminate that liability? Will Apple allow this to continue?
