I use the following command to build/archive my project:
xcodebuild -UseNewBuildSystem=NO -workspace WORKSPACE -scheme TARGET clean archive
The compilation fails with the following error:
error: -Werror=nsconsumed-mismatch is currently enabled, but was not in the PCH file
The same build command works when building against Xcode 10.2/10.3 and iOS 12 sdk.
