title: App Transport Setting exception domains not working xcode 7.3
body: <p>How do I set an exception domain?
  I want to load a map ttile eg from the domain <a href="http://map1.vis.earthdata.nasa.gov" rel="nofollow">http://map1.vis.earthdata.nasa.gov</a>.</p>
  
  <p>I have added an exception but it's not working.  Unless I use set "abritrary loads" instead I get the error "The resource could not be loaded because the App Transport Security policy requires the use of a secure connection."</p>
