/**
 * "X-macro" file that lists the flags names of Apple's Network Reachability
API, along with a nice
 * Objective-C method name used to query each of them.
 *
 * Example usage: To generate a dictionary from flag value to name, one can do:

  NSDictionary *flagNames = @{
#define GRPC_XMACRO_ITEM(methodName, FlagName) \
    @(kSCNetworkReachabilityFlags ## FlagName): @#methodName,
#include "GRXReachabilityFlagNames.xmacro.h"
#undef GRPC_XMACRO_ITEM
  };

  XCTAssertEqualObjects(flagNames[@(kSCNetworkReachabilityFlagsIsWWAN)],
@"isCell");
