ios - NSLocalisedString toggle between displaying key and translated text -

i have app localised, wandering if theres way toggle between displaying key , translated text either while app running or through debug build?

i want run through app , make sure there no hardcoded strings

thanks

not asking for, in xcode menu product -> scheme -> edit scheme… -> run -> options there option “show non-localized strings” capitalize strings in ui not localized.

i hope can solve problem.
