title: How to avoid UIWebView on Firebase/Auth
body: <p>I need to get a Firebase/Auth version where UIWebView has been replaced with WKWebView</p>
  
  <p>After an AppStore rejection due to use of UIWebView I'm trying to update to a version of Firebase pods which are not using it. But after pod update, pod install, pod deintegrate ... the Firebase/Auth version I can get Firebase/Auth (5.20.2):<br/>
  is still using UIWebView so how can I update to the latest version or any version not using UIWebView
  Below my Podfile and Podfile.lock</p>
  
  <pre><code># Uncomment the next line to define a global platform for your project
  #platform :ios, '9.0'
  
  #target 'globa_jap-desktop' do
    # Uncomment the next line if you're using Swift or would like to use dynamic frameworks
    # use_frameworks!
  
    # Pods for globa_jap-desktop
  
  #end
  
  target 'globa_jap-mobile' do
    # Uncomment the next line if you're using Swift or would like to use dynamic frameworks
    # use_frameworks!

  <p>I tried setting the a version for Firebase/Auth in the Podfile but fails due to uncompatibility with other pods<br/></p>
  
  <p>My last try was to get the last version of FirebaseCore straight from git <br/>
  pod 'FirebaseCore', :git => '<a href="https://github.com/firebase/firebase-ios-sdk.git" rel="nofollow noreferrer">https://github.com/firebase/firebase-ios-sdk.git</a>', :branch => 'master'<br/></p>
  
  <p>but failed with the following message</p>
  
  <pre><code>[!] CocoaPods could not find compatible versions for pod "GoogleUtilities/Logger":
    In Podfile:
      FirebaseCore (from `https://github.com/firebase/firebase-ios-sdk.git`, branch `master`) was resolved to 6.7.0, which depends on
        GoogleUtilities/Logger (~&gt; 6.5)
  
      FirebaseUI/Twitter was resolved to 6.2.1, which depends on
        FirebaseUI/Auth (= 6.2.1) was resolved to 6.2.1, which depends on
          GoogleUtilities/UserDefaults was resolved to 5.8.0, which depends on
