ios - How do I change the Development language in Xcode before internationalizing my app?

Question

I'm taking over an app that was written entirely in French. Strings are hardcoded in French in the code, and all the messages in the storyboard are in French. But the initial development region in Info.plist was left to English. So I changed CFBundleDevelopmentRegion to fr so that it matches the real language that was used. But XCode keeps telling me that my Development language is English:

How can I correct that? The goal is to be able to activate Base Internationalization and have it use French as the Base language instead of English.

Answer 1

The following procedure worked for me, but it includes manually editing project.pbxproj file:

1. Quit XCode
2. Open the project.pbxproj file with your favorite text editor
3. Update the following section (near developmentRegion):

OLD:

    developmentRegion = English;
    hasScannedForEncodings = 0;
    knownRegions = (
        en,
        Base,
    );

NEW:

developmentRegion = fr;
            hasScannedForEncodings = 0;
            knownRegions = (
                fr,
                Base,
            );

I've created a GitHub repository with a sample project that was initially created with English as default Development Language, and then updated by the procedure above to use French as Development Language.
