The application we're building is shaping up nicely. It's time to make it a little bit more functional. The application is currently only capable of fetching weather data for a predefined set of coordinates. This severely limits the appeal of the application.

In this episode, we use the Core Location framework to fetch the location of the device. The application will use that information to show the user weather data for their current location. That will make the application much more useful.
