!!! There's a better solution here now, that doesn't require swizzling:
!!! http://www.splinter.com.au/2014/09/10/afnetworking-error-bodies/
!!! But i'll leave the below swizzling solution up for old time's sake


//  AFURLSessionManager+ErrorResponse.h
//  This hacks AFURLSessionManager so that it returns the error response in failure callbacks, in the error's userInfo.

// Usage:
// [mySessionManager POST:@"some_api_endpoint" parameters:params success:^(NSURLSessionDataTask *task, NSDictionary *responseObject) {

// This is a drop-in Gradle script that allows you to easily strip out the packages you don't need
// from the Google Play Services library. The script will keep track of previous runs to prevent
// restripping each time you build.

// HOW TO USE THIS
//
// 1) Download/copy this strip_google_play_services.gradle file into the same location of your app's
//    build.gradle file.
