Look there

Try this :

CFArrayRef myArray = CNCopySupportedInterfaces();
CFDictionaryRef captiveNetWork = CNCopyCurrentNetworkInfo(CFArrayGetValueAtIndex(myArray, 0));
NSLog(@"Connected at : %@", captiveNetWork);
NSDictionary *myDictionnary = (__bridge NSDictionary *)captiveNetWork;
NSString *bssid = [myDictionnary objectForKey:@"BSSID"];
NSLog(@"BSSID : %@", bssid);
