title: cocoapods Sync: ld: framework not found DATAFilter, linker command failed with exit code 1
body: <p>I am trying to get Sync (<a href="https://github.com/hyperoslo/Sync" rel="nofollow noreferrer">https://github.com/hyperoslo/Sync</a>) to work in my 'em' Xcode iOS Swift project. I have experience with Carthage for framework dependency so it is my cocoapods premiere.</p>
  
  <p>my Podfile</p>
  
  <pre><code>use_frameworks!
  
  target "em" do
      pod 'Sync'
  end
  </code></pre>

  ld: framework not found DATAFilter

  <p>My question is - Is neccessary somehow manually link the DATAFilter framework?</p>
