title: CocoaPods get current dependency versions
body: <p>I have a project which uses CocoaPods. My Podfile specifies the dependencies required, however, I did not specify the versions that should be used.</p>
  
  <p>I'd like add explicit dependency versions to my Podfile, so that using <code>pod install</code> after checking out my project on a new computer would always fetch my current, not newest version of Pod dependency from CocoaPods.</p>
  
  <p>Is there a way to quickly check which version of each Pod dependency I currently have in my project directory?</p>
