        var addresses = [String]()

        

        // Get list of all interfaces on the local machine:

        var ifaddr : UnsafeMutablePointer<ifaddrs>?

Usage

 override func viewDidLoad() {

        super.viewDidLoad()

        let addr = getIFAddresses()

        print(addr[1])

        ipaddress=addr[1]

        

    }
