title: iOS app has mysterious UUID with no matching dSYM so cannot symbolicate
body: <p>I'm pretty familiar with how crash logs for iOS apps are symbolicated but this one is a head scratcher.</p>
  
  <p>I have MyApp with build 2345 that was released as a beta through TestFlight, using the normal Archive then Upload to App Store flow in Xcode 7.2 (7C68).</p>
  
  <p>When I do a dwarfdump for the binary in the the xcarchive, I get the following:</p>
  
  <pre><code>dwarfdump --uuid MyApp.app/MyApp
  UUID: 0BDA6D6F-3C0D-339E-842F-C2CB04199E10 (armv7) MyApp.app/MyApp
  UUID: B2A69BEC-DF5E-33EA-A9E0-490EBF03074C (arm64) MyApp.app/MyApp
  </code></pre>
  
  <p>Here is the dwarfdump for the dSYM file:</p>
  
  <pre><code>dwarfdump --uuid MyApp.app.dSYM
  UUID: 0BDA6D6F-3C0D-339E-842F-C2CB04199E10 (armv7) MyApp.app.dSYM/Contents/Resources/DWARF/MyApp
  UUID: B2A69BEC-DF5E-33EA-A9E0-490EBF03074C (arm64) MyApp.app.dSYM/Contents/Resources/DWARF/MyApp
  </code></pre>
  
  <p>So far, so good.</p>
  
  <p>However, I received a crash through Organize > Crashes for build 2345 that has a different UUID for the binary:</p>
  
  <pre><code>0x100054000 - 0x1000fffff myapp arm64  &lt;3715db2438743cf5aac1742d9a214c2c&gt; /var/mobile/Containers/Bundle/Application/7313BC02-3F90-4F94-82E2-CBDC941E5D68/MyApp.app/myapp
  0x100144000 - 0x1001e7fff AWSCore arm64  &lt;c2aa13236d0437b98194c0487db69e68&gt; /var/mobile/Containers/Bundle/Application/7313BC02-3F90-4F94-82E2-CBDC941E5D68/blink.app/Frameworks/AWSCore.framework/AWSCore
  ....
  </code></pre>
  
  <p>I know for sure that the crash report is for the same build, yet the UUID here is <code>3715db2...</code> when I am expecting it to be <code>b2a69bec...</code></p>
  
  <p>I do have bitcode enabled so I tried doing a Download dSYMs from the Organizer Archive page (even though I built arm64 so Apple shouldn't have had to) and it retrieved dSYMs for the other UUIDs/binaries in the crash report but nothing for the <code>myapp</code> binary.  In fact, the <code>myapp</code> binary is the only binary that didn't get a corresponding dSYM downloaded!</p>
  
  <p>So a couple questions:</p>
  
  <ol>
  <li>Where did the <code>3715db2438743cf5aac1742d9a214c2c</code> version of the
  myapp binary come from?</li>
  <li>How can I get the dSYM for it so that I can symbolicate the crash?  Apple is not returning it with the "Download dSYMs" option in Xcode.</li>
  </ol>
