Decode SimplePing response packet in Swift

I am using SimplePing sample from Apple to ping to a host which successfully received a response from the framework delegate 

 func simplePing(pinger: SimplePing!, didReceivePingResponsePacket packet: NSData!)

Which I am struggled to find the way to to decode the packet data (e.g. get the host name, ip)

I know that it's something about CFNetwork but I just can't find the right way to read the data, hope someone can help.

If anyone stumble upon this topic in pesent, like me. Host name or ip address can be found in pinger property. If that is what you looking for.

Example:

func simplePing(_ pinger: SimplePing, didReceivePingResponsePacket packet: Data, sequenceNumber: UInt16) {
    print("Host: \(pinger.hostName)")
}

The sample provides a method called icmpInPacket: that returns a broken-out struct. Use that. :-)
