I need to set Spanish as development language for an iOS app. I\'m already using Xcode 6, and I changed the Localization native development region entry in app\
For someone that needs help like I did, I have two targets, one I want to be EN Base localization and second target I need to be another language. The option mention above: "change projectname.xcodeproj/project.pbxproj and search for developmentRegion and change ..." doesn't work for me because of targets.
What worked for me, Xcode 11.5, is that only I need to change the language code in the "Localization native development region" for that particular target and it works, no need to change anything in projectname.xcodeproj/project.pbxproj P.S. Here "Localization native development region" must go country code like fr_Fr or in my case hr for Croatian
