title: could not find compatible versions for pod
body: <p>I am new in IOS development and git. I am having a problem after merging my local repo to the dev repo. After merging when I build the project I get an error in the Xcode that says, <strong>"The sandbox is not in sync with the Podfile.lock. Run 'pod install' or update your CocoaPods installation."</strong></p>
  
  <p><a href="https://i.stack.imgur.com/EW8Tc.png" rel="noreferrer">Build Error</a></p>
  
  <p>I searched about this and tried the usual solution reinstalling the pods. But executing </p>
  
  <pre><code>pod install
  </code></pre>
  
  <p>I get another error in terminal that says </p>
  
  <p><a href="https://i.stack.imgur.com/GhsGH.png" rel="noreferrer">Terminal Error</a></p>
  
  <p>At this point I tried deleting the files associated with the "FTPopOverMenu" pod and reinstalling with <em>pod install</em>. The error doesn't go away. Also, I tried solving it in this way - <a href="https://stackoverflow.com/a/22878202/9238916">Error:“The sandbox is not in sync with the Podfile.lock…” after installing RestKit with cocoapods
  </a></p>
  
  <p>But both error in the Xcode and in the terminal still remains. I'm new to IOS and Git. I really don't understand what is really happening here.</p>
