xcode - How to fix Core-Data old version(xcdatamodel)'s warning? -

i knew modifying core-data previous version breaks light-weight migration. have inverse relationship warnings on old versions of info model.

i tried removing old versions used before launching first version of our app. followed so question, "how delete old/unused info model version in xcode 4"

it removes warning(of course of study should) but cannot run our app anymore

i think should maintain every versions though not related light-weight migration

i saw so question, "how disable no inverse relationship warning coredata in xcode 4.2?". , tried setting momc_no_inverse_relationship_warnings yes.

it doesn't removes warning and don't want future mistake, missing inverse setting, ignored.

i think alternative not case

i don't want see compiler warning old version of info model(.xcdatamodel). because these models not used warnings not significant.

but want see future inverse relationship warning on newer version of info model.

what alternative can take?

xcode core-data compiler-warnings suppress-warnings
