+ * "X-macro" file that lists the flags names of Apple's Network Reachability API, along with a nice

+ * 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"

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