What is iOS App Localizer
iOS App Localizer is a powerful localization management system centered around String Catalogs, a new feature introduced by Apple in Xcode 15. It serves as a centralized platform for managing all text resources in iOS applications that need translation, including UI labels, error messages, and other user-facing content. The system replaces the traditional manual string internationalization process with an automated, more efficient workflow that helps developers and translators collaborate seamlessly to create fully localized iOS applications.
