localization

Apple's WWDC 2024 featured several sessions related to localization and translation, particularly focusing on the Translation API and building multilingual-ready apps.

Key Highlights:

1. Translation API:

   • The Translation API allows apps to perform translations using on-device machine learning models. These models are shared across all apps, including the Translate app, and can be used if the user has already downloaded the necessary languages.
   • Developers can specify source and target languages directly or use automatic language detection by setting the source language to nil. If the framework cannot determine the language, it will prompt the user to select one.
   • It's important to handle translation tasks correctly by attaching both translation presentation and translation task modifiers to the content. This ensures that the translation popover points to the correct view, especially on iPad and Mac.
   • For translating multiple strings, batch translation functions are recommended for efficiency.

2. Building Multilingual-Ready Apps:

   • Apps can respect the user's language and region settings, automatically using the correct numbering system and other formatting aspects like decimal separators.
   • Developers can allow users to choose an app-specific language independently of the device's overall language settings. This is particularly useful for multilingual users who prefer different languages for different apps.
   • String catalogs in Xcode have been enhanced to detect common validation issues and offer tools to manage translations effectively.

Relevant Sessions:

• Meet the Translation API: This session covers the Translation API, including language support and best practices for implementing translation features in apps.
• Build multilingual-ready apps: This session discusses how to create apps that are ready for multiple languages, focusing on localization and the use of string catalogs.

These sessions provide valuable insights into how developers can enhance their apps to support multiple languages and improve user experience through effective localization and translation strategies.
