title: iOS: Watch Kit paired device unavailable for development
body: <p>I can't run my Apple Watch application in XCode. My phone+watch is listed as a "Unavailable Device" and says "paired device unavailable for development". When I try to launch the app it says the same thing.</p>
  
  <p>How can I resolve this?</p>
  
  <p>I'm using XCode 7.1, iOS 9.0, WatchOS 2.0.1.</p>
