title: No devices attached in xamarin VisualStudio for ios
body: <p>I'm having real trouble when I try to use the IOS emulator from the visual studio. So I created a hello world app in VS using xamarin (latest stable version), I set the project as main project, and When I refresh the connexion with the mac, I can't select the device that should be shown in the selectList. The message is "No device attached" :</p>

  <p>And if I try to use xamarin studio on the host mac, all is okay, the sample app builds on the iphone emulator: </p>
