title: You must specify |clientID| for |GIDSignIn| error when trying to sign in with Google
body: <p>Google sign in was working fine with Xcode 7. After updating to Xcode 8, I started getting the error: <code>Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: 'You must specify |clientID| for |GIDSignIn|'</code>. I have a GoogleService-Info.plist file with my CLIENT_ID.</p>
  
  <p>I was able to fix it by adding the following line:</p>
  
  <pre><code>GIDSignIn.sharedInstance().clientID = "&lt;CLIENT_ID&gt;"
  </code></pre>
  
  <p>It seems the CLIENT_ID isn't being fetched from GoogleService-Info.plist. I've made sure it's in the Copy Bundle Resources.</p>

  <p>I shouldn't have to specify the client id in the code. How can I fix it to get the information from the GoogleService-Info.plist file?</p>
