Environment

• Using XCode 12.x
• NS 7.x

Issue

Metadata generation seems to be faulty if the CLANG_ENABLE_MODULES = YES

Steps (flavor doesn't matter):

• tns create test --js
• cd App_Resouces/ios
• edit build.xcconfig
  • Add CLANG_ENABLE_MODULES = YES
  • Save
• cd ../..
• ns build ios --for-device

The resulting metadata

Result: 19159 declarations from 40 top level modules Size of Metadata file (platforms/ios/build/Debug-iphoneos/) is ~1.3m 

Normal application without CLANG_ENABLE_MODULES reports:

Result: 45930 declarations from 155 top level modules Size of Metadata file is ~6.4m
