title: CocoaPods could not find compatible versions for pod "Firebase/Performance": when installed Firebase X in Ionic 5
body: <p>My project in Ionic 5 and using Capacitor 2.1.2. I have installed <a href="https://ionicframework.com/docs/native/firebase-x" rel="noreferrer">Firebase X</a> for capacitor using the following code.</p>
  
  <pre><code>npm install cordova-plugin-firebasex
  npm install @ionic-native/firebase-x
  </code></pre>
  
  <p>When I did <code>ionic cap sync</code>, the android installation was with no errors but I am getting the following error in IOS.</p>
  
  <pre><code>✖ Updating iOS native dependencies with "pod install" (may take several minutes): 
  ✖ update ios: 
  [error] Error running update: Analyzing dependencies
  [!] CocoaPods could not find compatible versions for pod "Firebase/Performance":
    In Podfile:
      CordovaPluginsStatic (from `../capacitor-cordova-ios-plugins`) was resolved to 2.1.2, which depends on
        Firebase/Performance (= 6.23.0)
  
  None of your spec sources contain a spec satisfying the dependency: `Firebase/Performance (= 6.23.0)`.
  
  You have either:
   * out-of-date source repos which you can update with `pod repo update` or with `pod install --repo-update`.
   * mistyped the name or version.
   * not added the source repo that hosts the Podspec to your Podfile.
  </code></pre>
  
  <p>The Capacitor IOS version is <code>"@capacitor/ios": "^2.1.2"</code></p>
