20  * "X-macro" file that lists the flags names of Apple's Network Reachability
21 API, along with a nice
22  * Objective-C method name used to query each of them.
23  *
24  * Example usage: To generate a dictionary from flag value to name, one can do:
25 
26   NSDictionary *flagNames = @{
27 #define GRPC_XMACRO_ITEM(methodName, FlagName) \
28     @(kSCNetworkReachabilityFlags ## FlagName): @#methodName,
29 #include "GRXReachabilityFlagNames.xmacro.h"
30 #undef GRPC_XMACRO_ITEM
31   };
32 
33   XCTAssertEqualObjects(flagNames[@(kSCNetworkReachabilityFlagsIsWWAN)],
34 @"isCell");
