LocalizationKit is an open source library submitted by William Powell that allows you to manage your translations and texts remotely without needing to resubmit to the app store.
Localization Kit was created so you could quickly fix localization mistakes, and add other languages. LocalizationKit also provides a web-based tool for managing the translations that is free to use and manage.
You can find LocalizationKit on Github here.
A great library and tool for managing your app localizations.
