Yes, I changed the city, and still no luck. I used Kaleidoscope to diff my Search.js file vs the completed project, and there were no differences. The only thing I can think of is that I am running Little Snitch, and it may have blocked the attempted connection from the simulator to the API, but I temporarily stopped the Network Monitor and tried again - and I got the same result.
Very perplexing.
