Craig Hockenberry on WatchKit

Craig Hockenberry:

Bluetooth Low Energy must be really low power: the design of WKInterfaceObject means it’s going to be on a lot. Every interaction with the watch has the potential to move actions and data between your pocket and wrist using the radio.

But more importantly, this API design gives Apple a simple way to put a cap on power consumption. We saw this approach in the early days of the iPhone and that worked out pretty well, didn’t it?

One final thought about the API design: your code never runs on the watch.
