title: Building the Facebook 3.x+ SDK on iOS
body: <p>I just downloaded the Facebook 3.27 SDK from the Facebook's developer account.</p>
  
  <p>In the getting started section (<a href="https://developers.facebook.com/docs/ios/getting-started" rel="nofollow">https://developers.facebook.com/docs/ios/getting-started</a>), it mentions "Then build the SDK from source before you compile and run any samples".</p>
  
  <p>It does not mention how to build the source.  Is this done through Xcode, or through a shell script?  If done through either, there is an error message where the build chokes on building "Bolts" with a "Directory not found".</p>
  
  <p>Any ideas on how I'm supposed to build the SDK?</p>
