Ionic build --prod IOS stops without a error message

I have run the command Ionic build --prod --verbose IOS, however, it runs and stops without saying why, I have been facing a lot of issues to build for IOS, only for IOS and I think it is related with firebase.

The first error was about the Node --max-old-space-size=8192 and now this one.

Anyone already face this issue?

Maybe it is not an error but anyway it is not generating the .xcodeproj file, what am I doing wrong?

Iā€™m experiencing this currently, did you resolve this?

I realise this is likely too late but I just found this while searching for something else, try running with this build flag:

ionic cordova build --release --prod ios -- --buildFlag="-UseModernBuildSystem=0"
