title: Get the network traffic statics on iOS
body: <p>I want to display the network traffic statistics in my iOS application. For that, I must detect the sent and received bytes and also the latency. I spent multiple hours on searching but I didn't find what I'm expecting.</p>
  
  <p>What is the best way to do that? In Android there is the <code>TrafficStats</code> class that allows to get the sent and received bytes. What about iOS?  </p>
