   ## Workaround
   I found a workaround for this. Following the build errors, I renamed the the folder at
   `/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.15.sdk/usr/include`
   to
   `/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.15.sdk/usr/include_old`
   and the problem seems to have gone away. Doesn't feel like a very robust fix, but it works for now. I'm no longer sure if this is a bug in cordova-ios.
   
   It seems like the above file was being included in the search paths by default by clang

   End of search list.
   ```
   
   Renaming the directory seems to have removed the following from the search path which was causing the issue.
   
   `/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/usr/include`
   
   This directory appears to be included by default in the latest version of Xcode. Is it possible for the cordova project to explicitly ignore it?
