title: xCode 9.3 and Firebase Crashlytics not working
body: <p>I cannot get Firebase Crashlytics to show my crashes of my xCode iOS Swift app.</p>
  
  <ul>
  <li>Using xCode 9.3</li>
  <li>I have manually (not using cocoapods) integrated the Crashlytics SDK
  as specified here:
  <a href="https://firebase.google.com/docs/crashlytics/get-started?authuser=0" rel="nofollow noreferrer">https://firebase.google.com/docs/crashlytics/get-started?authuser=0</a></li>
  <li>I have tested both in the simulator and on the device</li>
  <li>I made both crash (using an own written crash function, but also the supplied crash function), I restarted the device/simulator (because the crash is only transmitted upon the next launch)</li>
  <li>I am not seeing any crashes in the Firebase Crashlytics console, it keeps on saying "Upgrade to Crashlytics for more powerful, realtime crash analysis"</li>
  <li>I can confirm in the xcode debug console logs that the crashlytics is running because I see "[Crashlytics] Version 3.10.1 (129)"</li>
  <li>I disabled bitcode does not change anything...</li>
  <li>I looked in the system console and found: </li>
  </ul>

  <li>Its like 9 crashes are pending/hanging? What is this cancelled?</li>
  <li>I figured, maybe its because there are no dsyms uploaded so I checked the build process in xCode and found:</li>

  <ul>
  <li>What does this "launched uploader in validation mode" mean? Does it mean that the dsym upload is not working?</li>
  <li>I wanted to manually upload the dsyms using : <a href="https://firebase.google.com/docs/crashlytics/get-deobfuscated-reports?authuser=0" rel="nofollow noreferrer">https://firebase.google.com/docs/crashlytics/get-deobfuscated-reports?authuser=0</a> but the fabric.framework does not contain any upload-symbols? The Google documentation wrong? I can see an "uploadDSYM" but this does not seam to have the same options/arguments so I guess its not this one...?</li>
