ios - Network Connection Checker via Reachability class swift 2.0 -

i trying check internet connection status via reachability.swift class has written in swift 2.0. here class code:

import uikit import foundation import systemconfiguration  public class reachability: nsobject {      class func isconnectedtonetwork() -> bool {          var zeroaddress = sockaddr_in(sin_len: 0, sin_family: 0, sin_port: 0, sin_addr: in_addr(s_addr: 0), sin_zero: (0, 0, 0, 0, 0, 0, 0, 0))         zeroaddress.sin_len = uint8(sizeofvalue(zeroaddress))         zeroaddress.sin_family = sa_family_t(af_inet)          let defaultroutereachability = withunsafepointer(&zeroaddress) {             scnetworkreachabilitycreatewithaddress(kcfallocatordefault, unsafepointer($0))         }          var flags: scnetworkreachabilityflags = scnetworkreachabilityflags(rawvalue: 0)         if scnetworkreachabilitygetflags(defaultroutereachability!, &flags) == false {             return false         }          let isreachable = flags == .reachable         let needsconnection = flags == .connectionrequired          return (isreachable && !needsconnection)      } } 

my question this; when connected cellular network class not recognise means isconnectedtonetwork() method returns false on iphone 5 device, not simulator. situation there? please ant appreciated, thanx...

along reachable , connectionrequired need check too.

let iswan = flags = .iswwan 

if either of reachable or iswwan set connected network. iswwan tells if specified node name or address can reached via cellular connection, such edge or gprs.
