title: ld: library not found for -lCocoaAsyncSocket
body: <p>I'm using App Center to manage the build for iOS and the following is error I'm receiving in the build output:</p>
  
  <pre><code>    ld: library not found for -lCocoaAsyncSocket
  clang: error: linker command failed with exit code 1 (use -v to see invocation)
  
  ** ARCHIVE FAILED **
  
  ##[error]Error: /usr/bin/xcodebuild failed with return code: 65
  </code></pre>
  
  <p>I ran the build in Xcode and the archive was successful.</p>
  
  <p>Any thoughts on why this fails in App Center ?</p>
