title: No such module 'FirebaseDatabase'
body: <p>I am developing iOS app with Swift 3 with Firebase database.</p>
  
  <p>My Podfile:</p>
  
  <pre><code>target 'MyApp' do
    # Comment the next line if you're not using Swift and don't want to use dynamic frameworks
    use_frameworks!
  
    # Pods for MyApp
    pod 'Firebase/Core'
    pod 'Firebase/Auth'
    pod 'Firebase/Database'
  end
  </code></pre>
  
  <p>I run <code>pod install</code>, which installs the pods.</p>
  
  <p>I created a class:</p>
  
  <pre><code>import Foundation
  import FirebaseDatabase // Error: no such module 'FirebaseDatabase'
  
  class MyDatabase {
      var ref: DatabaseReference!
      ...
  }
  </code></pre>
  
  <p>But I get compiler error <code>no such module 'FirebaseDatabase'</code>, why?</p>
