My app crashes with an unknown key exception on the refreshWeather function. This error occurs on the AppDelegate controller:
2016-05-06 07:16:41.400 Stormy[970:38861] *** Terminating app due to uncaught exception 'NSUnknownKeyException', reason: '[<Stormy.ViewController 0x7fa942e868e0> setValue:forUndefinedKey:]: this class is not key value coding-compliant for the key refreshWeather.'
