只能在string catalog里面添加语言，不能删除语言？？这是什么设计？ 在Project里面删除语言，并不能删除Localizable中的语言。但是如果这个语言没有任何国际化，是可以的。
也就是说，删不了曾经做过国际化的语言。
我应用还没发布，还在开发呢，为什么不让我删除语言？？？？？？？？？？？？？？？？？？？？？？？？？？、
I've been using a handy tool specifically designed for this purpose: XCStrings File Processor: (https://www.swifthub.org/xcstringstool/). It's a browser-based tool that lets you easily manage languages in your .xcstrings files. The workflow is straightforward:
1.Upload your .xcstrings file (drag & drop or click to select) 2. You'll see a list of all available languages in your file 3. Simply uncheck the languages you want to remove 4. Click "Process File" and download the updated version
What I particularly like about it is that everything is processed locally in your browser - no file uploads to any server, which is great for sensitive project files. It's also quite useful when you need to create region-specific builds or want to reduce your app size by removing unused localizations.
I've found it much more efficient than manually editing the .xcstrings file, especially when dealing with large localization files. The tool is free to use and doesn't require any registration.
Hope this helps with your localization management!
