How to remove a language from String Catalog?

I have accidentally added a new language in String Catalog by pressing a + button at the bottom.

However, there is no - button to remove it(like in Targets for example) and also there is nothing in attributes inspector.

If I select it and press back button on keyboard, it will not show a delete pop-up as it usually does in Xcode. Is there any way to delete it?

Solution

I had this problem today, so I made a python script to modify the file. If you don't use python on your computer, you can use CodeSpaces to setup an area to run the code below.

Open your catalog file as source code
Simply Copy & Paste the JSON from your Localizable.xcstrings file to an input file (ie local_in.txt)
Copy and paste the code below into a python file (ie delocalize.py)
Make sure the .txt and .py files are in the same directory
Then run the .py file (ie: python delocalize.py)
You'll get an output file (ie: local_out.txt) that you can paste back to your Localizable.xcstrings file using FileManager and TextEdit

import json

def remove_localizations(input_filepath, output_filepath, languages_to_remove):

    with open(input_filepath, 'r', encoding='utf-8') as file:      # Load the JSON data from the file
        data = json.load(file)

    for string_key in list(data["strings"].keys()):                 # Remove specified languages from the 'strings' section
        string_data = data["strings"][string_key]
        if "localizations" in string_data:                          # Check if 'localizations' exists before trying to access it
            for lang in languages_to_remove:
                if lang in string_data["localizations"]:
                    del string_data["localizations"][lang]

    with open(output_filepath, 'w', encoding='utf-8') as file:     # Write the updated JSON data back to a file
        json.dump(data, file, indent=2, ensure_ascii=False)


input_filepath      = 'local_in.txt'        # Name of file with all languages       (ie: 'local_in.txt' file in the same directory, so use the relative path)
output_filepath     = 'local_out.txt'       # Name of file with the the new changes (ie: 'local_out.txt' the original or you can overwrite the file if you want)
languages_to_remove = ['de', 'fr']          # Languages to remove                   (in my case, I only wanted to keep the root ('en') language and 'jp')

# Call the function to remove the languages
remove_localizations(input_filepath, output_filepath, languages_to_remove)
