How to Localize iOS Strings: A Complete Guide for Developers

Localization is an essential part of creating an inclusive and user-friendly iOS app. By translating your app’s strings into multiple languages, you can cater to a global audience, improve user engagement, and significantly boost your app’s downloads and revenue. In this guide, we’ll explore the process of localizing iOS strings and introduce Easily Translate, a powerful tool that simplifies string localization for developers and non-developers alike.

What Does It Mean to Localize iOS Strings?

String localization is the process of adapting the text in your app (like labels, buttons, alerts, and menus) to different languages and cultural contexts. In iOS, this involves using Localizable.strings files, which store all user-facing text in key-value pairs. By localizing these strings, your app can dynamically display content in the user’s preferred language.

Why Should You Localize iOS Strings?

  • Expand Your Reach: Offering your app in multiple languages opens the door to global markets. English alone covers only a fraction of potential users worldwide.
  • Improve User Experience: Users are more likely to engage with apps that speak their language and respect their cultural preferences.
  • Boost App Downloads: Localized apps have better visibility in the App Store because they can target keywords in different languages.
  • Stay Competitive: In a crowded marketplace, localization gives you an edge over apps that only support one language.

The Challenges of Localizing iOS Strings

  • Managing Multiple Localizable.strings Files: Handling strings for multiple languages can quickly become overwhelming.
  • Ensuring Translation Quality: Poor translations can lead to misunderstandings and frustrate users.
  • Consistency Across Updates: Adding new strings during app updates can disrupt your localization workflow.
  • Testing Localized Content: Ensuring your UI works correctly in all languages requires thorough testing.

Step-by-Step Guide to Localizing iOS Strings

  1. Extract Strings: Use NSLocalizedString macros to extract user-facing text from your code and create a Localizable.strings file.
  2. Upload to Easily Translate: Import your Localizable.strings file into the app and choose the target languages you want to support.
  3. Translate Strings: Easily Translate will generate accurate translations for your strings, ensuring they align with the context of your app.
  4. Export Translations: Export the localized strings from Easily Translate and add them to your Xcode project.
  5. Test Your App: Use Xcode’s built-in localization tools to test your app in different languages and verify that the UI adapts correctly.

Best Practices for Localizing iOS Strings

  • Use Descriptive Keys: Avoid generic keys like button1 or label2. Use meaningful keys that describe the string’s purpose.
  • Keep Strings Contextual: Provide context for translators to ensure accurate and culturally appropriate translations.
  • Test for UI Compatibility: Check that all text fits within UI elements and adjust layouts for languages with longer or shorter words.
  • Update Regularly: Keep your Localizable.strings files up-to-date with new content and features.
