How to get ipaddress when connected to mobile data swift3

Question

I am getting ipaddress of the phone in this way.

func getIPAddress() -> String? { var address : String? var ifaddr : UnsafeMutablePointer<ifaddrs>? = nil if getifaddrs(&ifaddr) == 0 { var ptr = ifaddr while ptr != nil { defer { ptr = ptr?.pointee.ifa_next } let interface = ptr?.pointee let addrFamily = interface?.ifa_addr.pointee.sa_family if addrFamily == UInt8(AF_INET) || addrFamily == UInt8(AF_INET6) { if let name:String = String(cString: (interface?.ifa_name)!), name == "en0" { var hostname = [CChar](repeating: 0, count: Int(NI_MAXHOST)) getnameinfo(interface?.ifa_addr, socklen_t((interface?.ifa_addr.pointee.sa_len)!), &hostname, socklen_t(hostname.count), nil, socklen_t(0), NI_NUMERICHOST) address = String(cString: hostname) } } } freeifaddrs(ifaddr) } return address }

But this returns when connected to wifi only. How to get ipaddress when I connected to mobile data.

That code looks familiar! – Note that it explicitly checks for the "en0" interface (which is the WiFi interface on iOS devices). To get a list of all interface addresses have a look at stackoverflow.com/a/25627545/1187415. — Martin R

@MartinR Thanks for the comment yeas I can take the address when im on mobile data as well now. But I have a small problem. when I connected to wifi it retrns ipaddress as 1st value but when on mobile data it returns as 0th location so how can I check whether its mobile data or wifi inorder to refer the correct index? — user1960169

@user1960169 for mobile data the interface name has prefix pdp_ip, for wifi has prefix en — user3441734

@user3441734 oh thanks so all I need to do is check for en0 and pdp_ip? — user1960169

To get IPAddress of device on turning Wifi or Mobile data ON, use below method :

func getIPAddress() -> String? { var address : String? // Get list of all interfaces on the local machine: var ifaddr : UnsafeMutablePointer<ifaddrs>? guard getifaddrs(&ifaddr) == 0 else { return nil } guard let firstAddr = ifaddr else { return nil } // For each interface ... for ifptr in sequence(first: firstAddr, next: { $0.pointee.ifa_next }) { let interface = ifptr.pointee // Check for IPv4 or IPv6 interface: let addrFamily = interface.ifa_addr.pointee.sa_family if addrFamily == UInt8(AF_INET) || addrFamily == UInt8(AF_INET6) { // Check interface name: let name = String(cString: interface.ifa_name) if name == "en0" || name == "pdp_ip0" { // Convert interface address to a human readable string: var hostname = [CChar](repeating: 0, count: Int(NI_MAXHOST)) getnameinfo(interface.ifa_addr, socklen_t(interface.ifa_addr.pointee.sa_len), &hostname, socklen_t(hostname.count), nil, socklen_t(0), NI_NUMERICHOST) address = String(cString: hostname) } } } freeifaddrs(ifaddr) return address }

Here if name == "en0" || name == "pdp_ip0" works for both Wifi and Mobile data.

Hope will be helping! :)
