I have a sample project where I reproduce easily this issue: Localizable.strings French file: "localizable_file" = "French"; Danish file: "localizable_file" = "Danish"; and InfoPlist.strings French file: "NSLocationWhenInUseUsageDescription" = "French location when in use usage"; Danish file: "NSLocationWhenInUseUsageDescription" = "Danish location when in use usage"; I show "French" in a label and "Danish location when in use usage" when I request the location permission. I also tried to add base.lproj with both Localizable.strings & InfoPlist.strings and the problem persist. I also remove Danish language and add Catalan, Italian, Finnish... languages and no problems. Then I re-add Danish and surprise it does not work anymore.
