I did following things in order to get the exact IP address of the device. Since I want to include the updated code to get IP address using Swift 3, I am posting the answer here. Referred from Swift - Get device's IP Address
Add #include in your bridging header
Create following function in order to get the IP Address.
func getIP()-> String? {
var address: String?
var ifaddr: UnsafeMutablePointer? = nil
if getifaddrs(&ifaddr) == 0 {
var ptr = ifaddr
while ptr != nil {
defer { ptr = ptr?.pointee.ifa_next } // memory has been renamed to pointee in swift 3 so changed memory to pointee
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" { // String.fromCString() is deprecated in Swift 3. So use the following code inorder to get the exact IP Address.
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
}
In order to get the IP Address, print(getIP())
For verification:
-> Goto Settings -> Wi-Fi -> Click i symbol -> you can check your device IP Address.
