I tried accessoryCorner and had several problems -- for one thing, I can only get a couple of letters in before it starts cutting off on that line of text; and for another, I have to apply an arbitrary ~0.65 scale to my progressview for it to not be too big for the corner view area. I guess WidgetKit isn't quite ready for prime-time yet.

Update: I was able to get the location authorization to Always, but my location update handler is still not being called most of the time -- I'll try setting the simulator to a few different locations and occasionally my breakpoint in the handler will be hit, but most of the time, it will not. Sometimes it'll get hit in rapid succession as several previous locations come through at once. Is this simply not possible, and I have to depend on getting the location from the main iOS app or while the watch app is active?

Never mind, it is stationary, the model was just scaled so much that it made it seem like it wasn't moving.
