I have a slider control in my watch app, but I'd like the user to use the crown to scroll through larger numbers, instead of tapping on the increase/decrease buttons a hundred times. Is this possible?
Unfortunately, you can't respond to the crown scrolling. This is from an Apple evangelist on https://devforums.apple.com/thread/254540?tstart=15
From a Watch app's point of view, a wearer who's using the digital crown is indistinguishable from a wearer who's scrolling the interface with a finger. There are no scroll callbacks for either case.
