title: reachability bug in Xcode 8 e Swift 3
body: <p>I have a huge problem!
  I'm trying to implement reachability in an app using Xcode 8 Beta 3 and Swift.</p>
  
  <p>When the user have internet (wifi or 4G): the background turns green. If you will not the background it will be red. And if the user accessing internet in a cellular, the background it will be yellow.</p>
  
  <p>The code runs well, but when I turn off the wifi, it breaks</p>
  
  <p>Here my github project - my "single view application"</p>
