title: React Native Firebase error Thread 1 SIGABRT - iOS
body: <h1>Problem</h1>
  
  <p>After following the tutorial for <a href="https://rnfirebase.io/docs/v3.0.*/installation/ios#4.-Setup-Firebase-Pods" rel="noreferrer">react-native-firebase</a>, my app hangs after a successful build. The error I get in Xcode is: <code>Thread 1: signal SIGABRT</code>. I understand from other questions that this has something to do with connections, but I do not know why this error occurs.</p>
  
  <p>This is my first React Native project and first time working with Xcode.</p>
  
  <h1>What I did</h1>
  
  <ol>
  <li>I added <code>react-native-firebase</code> and <code>firebase</code>.</li>
  <li>Ran <code>react-native link react-native-firebase</code>.</li>
  <li>Added the GoogleService-Info.plist to the project by dragging it into the Xcode editor.</li>
  <li>Stopped all Xcode tasks and quitted Xcode.</li>
  <li>Did a <code>pod init</code>.</li>
  <li><p>Adjusted the podfile to the following:</p>
  
  <pre><code># Uncomment the next line to define a global platform for your project
  platform :ios, '9.0'
  
  target 'Enso' do
  # Uncomment the next line if you're using Swift or would like to use dynamic frameworks
  # use_frameworks!
  
    # Pods for Enso
      pod 'Firebase/Core'
  
  end
  </code></pre></li>
  <li>Did a <code>pod install</code></li>
  <li>Opened the xcworkspace file</li>
  <li>Added the <code>#import &lt;Firebase.h&gt;</code> and <code>[FIRApp configure];</code> to <code>AppDelegate.m</code></li>
  <li>Cleaned the project</li>
  <li>Run the project</li>
  <li>Project build successful, but the app keeps hanging on the white screen with the name of the app and 'Powered by React Native'.</li>
  <li>After about 10 seconds the Xcode editor will show me the following: <a href="https://i.stack.imgur.com/iWE3i.jpg" rel="noreferrer">Image with error in Xcode</a></li>
  </ol>
