iOS builds on debug but on release mode returns "No such module ..."

I'm building on Release mode and I get:

    Swift Compiler Error
    No such module 'geofencing'

What i've already done:

    Flutter clean
    Flutter build ios

in /ios:

    pod deintegrate
    pod cache clean --all
    rm -r Flutter/Flutter.framework
    rm Podfile.lock
    pod install

Clean with xcode aswell, my framework search path is $(SRCROOT) as recursive

This is kinda frustrating :(

PS. The app does compile in Debug and builds the archive
