title: Running c or c++ code in standalone Xcode playground
body: <p>I would like to create a standalone playground and just drop a bunch of swift code into the Sources folder. I also have dependency on c/c++ code, so I also dropped those, and added a Bridging Header. </p>
  
  <p>These bunch of files compiled together in an Xcode project. However, i can't get them to work as a standalone Playground. Note that I aint trying to write c in the playground, but Swift code that in terms are wrapper for that C. </p>
  
  <p>Any idea how thats done? if possible.</p>
  
  <p>Note: Not sure why my Q is voted down. It is legit. Again, I plan to write Swift code in playground, but need a 3rd party library that has C files in it.</p>
