title: No such module 'Firebase' , cannot import Firebase Into Swift 4
body: <p>I am building an iOS app and it is my first experience using Firebase database. In Xcode 10.1 and swift version 4.2, I am trying to import Firebase into my classes. In a swift file, I have imported the database by "import Firebase".</p>
  
  <p>But unfortunately, I am getting an error that says  No such module 'Firebase’. </p>
  
  <p>This is my podfile:</p>
  
  <pre><code># Uncomment the next line to define a global platform for your project
  # platform :ios, '9.0'
  
  target 'Jawwab' do
    # Comment the next line if you're not using Swift and don't want to use dynamic frameworks
    use_frameworks!
    pod 'EstimoteProximitySDK', '~&gt; 1.0'
    # Pods for Jawwab
  pod 'Firebase/Core'
  pod 'Firebase/Auth'
  pod 'Firebase/Storage'
  pod 'Firebase/Database'
  end
  </code></pre>
  
  <p>Any help would be greatly appreciated.</p>
