title: Firebase Analytics events on iOS - test and production
body: <p>The iOS app I am working on uses <code>Firebase Analytics</code> to report events. It works as expected, but the app is not in production yet. Once it is it would be preferable to have the events logged by real users separate from these logged when debugging. </p>
  
  <p>What is the best way to have <code>Firebase Analytics</code> events logged separately for test and production?  </p>
