It’s been a bit over a year since we got the Apple Watch, and
right at a year since we got watchOS 2. Back then, we were
excited to be given a way to interact with the digital crown. You created a
WKInterfacePicker in IB, filled it with picker items, and
it would react to the crown for you. It was usable, but limited. It required
you to give up screen space, even though you could make it invisible.
