title: iOS Firebase import warning & error
body: <p>I always get the following warning by importing the Firebase Framework in my <code>AppDelegate.swift</code>:</p>
  
  <pre><code>import Firebase -&gt; File 'AppDelegate.swift' is part of module 'Firebase'; ignoring import
  </code></pre>
  
  <p>And the following error in the <code>didFinishLaunchingWithOptions:</code>:</p>
  
  <pre><code>FIRApp.configure() -&gt; Use of unresolved identifier 'FIRApp'
  </code></pre>
  
  <p><br>
  I imported the Firebase Framework with CocoaPods.
  That's my Podfile:</p>
  
  <pre><code># Uncomment this line to define a global platform for your project
  # platform :ios, '9.0'
  
  target 'Firebase' do
    # Comment this line if you're not using Swift and don't want to use dynamic frameworks
    use_frameworks!
  
    # Pods for Firebase
    pod 'Firebase'
    pod 'Firebase/Messaging'
  
  end
  </code></pre>
  
  <p><strong>Any idea what I'm doing wrong?</strong></p>
