Localization is simply the process of translating your app into multiple languages.
In situation like you need support multiple language, including API response messages and dynamic strings you need a list of localizable .strings file,
and you need to localized it based on the Language you want ( e.g English, Chinese, Japanese ).
i have 400 strings that needs to be localized in 3 or more languages 400 x 3 = 1,200
Just copy and paste your 1,200 lines of string!
To solve the pain of copy and pasting and save time.
you can use the tool called csv-localizer
