title: The file libswiftCore.dylib doesn’t have the correct code signature
body: <p>I know this question is asked many time and people's proposed many solutions. In my case, I have tried all of them. what I tried is
  FYI: I can't use xcode for the build.
  <strong>Reason:</strong> I am working on chromium ios code everything build using GN build system.</p>
  
  <ul>
  <li>Created SwiftSupport folder and make it part of ipa file.</li>
  <li>Also signed Dylib under my framework and under SwiftSupport folder.</li>
  <li>a complete application is signed with the same identity verified through a terminal.</li>
  </ul>
  
  <p>Does anyone have an idea what else apple required for signing? 
  More troubleshooting steps most welcome.</p>
