title: Apple Watch app installation issue - NSExtensionPointIdentifier
body: <p>I'm trying to install an app with WatchKit App and WatchKit Extension onto an iOS8.1 phone, from Xcode 6.2.</p>
  
  <p>I have the Deployment Target set at 8.1
  and the Base SDK at 8.2.</p>
  
  <p>I get this error:</p>
  
  <pre><code>This app contains an app extension that specifies an extension
  point identifier that is not supported on this version of iOS
  for the value of the NSExtensionPointIdentifier key in its Info.plist
  </code></pre>
  
  <p>I've seen some similar questions but not found a solution that works. Is there a way to programmatically handle the lower iOS version?</p>
