After doing more research I found out that the right approach is to use libTooling
based tools. As stated in their documentation:
Clang Tooling needs a compilation database to figure out specific build options for each file. Currently it can create a compilation database from the compile_commands.json file
For Xcode projects, this file can be generated like this:
xcodebuild -project PROJECT_NAME.xcodeproj | xcpretty -r json-compilation-database --output compile_commands.json
you will need to install the xcpretty
gem. (gem install xcpretty
)

UPDATE:
IF like me, you are having issues with the compile_commands.json
file generated from xcodebuild logs, just pass this commands to your binary:
-mios-simulator-version-min=10.0 -isysroot /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator.sdk -isystem /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/lib/clang/10.00/include -I/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/include/c++/v1 -I/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator.sdk/usr/include -F/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator.sdk/System/Library/Frameworks
You might need to update some of the parameters based on your system configuration but this is working fine for me currently.
