body: <p>how i can insert my unity project(2017.2.0f3) into my viewcontroller in xcode 9.0?</p>
  
  <p>In <a href="https://www.youtube.com/watch?v=RUmrRHeS7BU" rel="nofollow noreferrer">this guide</a>, actually outdated, i got the following error : </p>
  
  <p><code>clang: error: unknown argument: '-weak-LSystem'</code></p>
