Localize iOS Apps with String Catalogs in Xcode 15

In this tutorial, I show you how to translate and localize an iOS app with string catalogs in Xcode 15. Localizing your app and managing string resources can be a difficult task, but with the new string catalogs feature in Xcode 15, it has become much easier. In this video, I walk you through the process of working with string catalogs and converting an existing project.

First, I demonstrate how to create a new string catalog in a completely new project. String catalogs are based on the same file as the legacy strings files, which means you can use string catalogs for projects that support older iOS versions as well.

Next, I guide you through the process of adding translations for different languages in the string catalog. I show you how to add languages like German and French, and how to add translations for specific strings. I also explain how Xcode automatically tracks all the strings in your project and shows you which ones are localized and which ones are not.

I then demonstrate how to test the translations in the simulator and in SwiftUI previews. I show you how to change the language settings in the simulator and how to generate new locales for testing different languages in SwiftUI previews.

After that, I explain how to migrate an existing project from using localizable strings files to using string catalogs. I show you how to automatically migrate the strings files to the new string catalog and how to localize other files like the Info.plist file.

Next, I discuss more advanced cases like handling plural forms and formatting dates in different languages. I explain how to handle plurals using the localized string resource.
