title: WatchKit apps must have a deployment target equal to iOS 8.2 (was 8.3)?
body: <p>I just downloaded Xcode 6.3 beta 4, and my WatchKit app now fails to build with an error:</p>
  
  <pre><code>Embedded Binary Validation Utility Error
  error: WatchKit apps must have a deployment target equal to iOS 8.2 (was 8.3)
  </code></pre>
  
  <p>The iOS app and the project actually have a deployment target of 7.1 and always have, but we've been working with the iOS 8.3 SDK for our WatchKit component (using Swift 1.2) without issue using Xcode 6.3 beta 1, 2 and 3. This error only arose with Xcode 6.3 beta 4.</p>
  
  <p>Anyone else have this error, and know how to fix it?</p>
