title: Failing to add newly created cocoa pod to private pod spec
body: <p>I'm following to following tutorial - <a href="https://www.raywenderlich.com/5823-how-to-create-a-cocoapod-in-swift" rel="nofollow noreferrer">How to Create a CocoaPod in Swift</a>.</p>
  
  <p>I'm stuck at the last step - <strong>Using Your New CocoaPod</strong></p>
  
  <blockquote>
    <p>You first need to add your Podspec to a private specs repo; this lets
    CocoaPods find the pod when you try to install it. Fortunately, you’ve
    already created a Git repo for this, so this final step is relatively
    straightforward.</p>
    
    <p>Enter the following in Terminal, making sure you’re still in the
    RWPickFlavor directory:</p>
  </blockquote>
  
  <pre><code>pod repo add RWPodSpecs [Your RWPodSpecs Git URL]
  pod repo push RWPodSpecs RWPickFlavor.podspec
  </code></pre>
  
  <p>I get this fatal error:</p>
  
  <p><strong>fatal: destination path 'RWPodSpecs' already exists and is not an empty directory.</strong></p>
  
  <p>I've removed the repo and created it again according to the "Setting Up Your GitHub Repo" tutorial step. But I get this error still. </p>
  
  <p>Any ideas? </p>
