title: What is the difference between installing regular Firebase & Firebase core in iOS?
body: <p>I am new in Firebase. According to their setup guide for iOS, when I'm creating new app to configure Firebase in console, I should add <code>pod 'Firebase'</code> in the podfile.</p>
  
  <p>It was also mentioned that by default, this pod includes <code>firebase-analytics</code>. But then what is the use of <code>pod 'Firebase/Core'</code>? Since it also includes Analytics.</p>
  
  <p>I'm really confused. Do I need to include <code>pod 'Firebase/Core'</code> too?</p>
