How to disable Xcode warning "Enable Base Internationalization"?

Question

This warning started to appear on Xcode 10 Beta 6.

I perfectly understand its meaning, yet I wish to disable it. Any way to do that?

Answer 1

The warning will go away if you edit your project.pbxproj (inside of your xcodeproj) with an editor and add Base to the knownRegions key.

Not sure if it has any side effects though.

knownRegions = (     en,     nl,     Base, );
