I am working with the Forecastr wrapper library (https://github.com/iwasrobbed/Forecastr) to grab data from the website Forecast.io. Currently in the example project provided in the github project, the output spits out:

Now the library states this is JSON and this looks like JSON, but it actually is not JSON so I am unsure of how to go about parsing this NSString in my Xcode project.
SOLUTION:
It is a NSDictionary of type id. Thus to parse it as mvanallen states do this:
NSLog(@"Summary: %@",[json valueForKeyPath:@"currently.summary"]);
..should print out:
Summary: Humid and Overcast
Looking closer at the code there are certain externs such as:
extern NSString *const kFCCurrentlyForecast;
Therefore I can also do something like:
NSLog(@"%@",[[JSON objectForKey:kFCCurrentlyForecast] objectForKey:kFCApparentTemperature]);
