  <p>I have been looking around for an answer, and there is a lot of post regarding clang: error: linker command failed with exit code 1 (use -v to see invocation), but none seems to work in my case. </p>
  
  <p>I am stuck at this moment and are hoping for some help. Any help is appreciated.</p>
  
  <p>I am using Xcode Version 9.2 (9C40b) and Unity3D 2017.3.0p4. I am also using the latest Facebook SDK (v7.11.0) for Unity.</p>
