title: Download latest version of MapboxNavigation iOS Fails
body: <p>I'm trying to update MapboxNavigation -&gt; I'm currently use <code> pod 'MapboxNavigation', '~&gt; 0.40.0'</code>
  I'm trying to install the latest version of MapboxNavigation using <code>pod 'MapboxNavigation', '~&gt; 2.0'</code></p>
  <p>but I still get this pod installation output :</p>
  <pre><code>    [!] CocoaPods could not find compatible versions for pod &quot;MapboxNavigation&quot;:
    In Podfile:
      MapboxNavigation (~&gt; 2.1)
  
  None of your spec sources contain a spec satisfying the dependency: `MapboxNavigation (~&gt; 2.1)`.
  
  You have either:
   * mistyped the name or version.
   * not added the source repo that hosts the Podspec to your Podfile.
  </code></pre>
  <p>I tried to clean cache, remove pods.lock and still get the same result,</p>
  <p>can anyone help.</p>
