title: MinimumOSVersion is not acceptable
body: <p>I have updated xcode to version 6.3 and converted my swift code to version 1.2.</p>
  
  <p>I'm ready to publish an update on AppStore but it give me an error when uploading my archive:</p>
  
  <p>ERROR ITMS-90068: "This bundle is invalid. The value provided for the key MinimumOSVersion '8.3' is not acceptable."</p>
  
  <p>The problem is that I have no other SDK version available on xcode. In my build settings tab only iOS 8.3 is available.</p>
  
  <p>Any idea?</p>
