Improving Accuracy of Localizations in Xcode

September 16, 2024

Localization can be a daunting task for app developers. Handling edge cases like idiomatic expressions, context-dependent phrases, and language-specific nuances often makes the process complex and time-consuming. Misinterpretations can lead to awkward translations, affecting user experience and app ratings.

Thankfully, Xcode offers a solution with its support for comments in localized strings. By adding context directly to your strings, you provide translators—human or AI—with the necessary information to generate accurate translations. This is especially beneficial when your strings are translated using AI, as the additional context helps in understanding the intended meaning.

Why Use Comments in Localized Strings?

  • Clarify Ambiguity: Words that have multiple meanings can be clarified with comments.
  • Provide Context: Explain where and how the string is used within the app.
  • Specify Formatting: Indicate any specific formatting requirements or placeholders.

How to Add Localized String Comments

SwiftUI Example When using SwiftUI, you can add comments directly in your code and localization files.

// Comment: Title for the submit button in the login form
Text("Submit", comment: "Title for the submit button in the login form")

Objective-C Example For Objective-C projects, the process is similar but uses different syntax.

// Title for the welcome message on the home screen
NSLocalizedString(@"WelcomeMessage", @"Title for the welcome message on the home screen");

Enhancing AI Translations with Comments

At String Catalog, we automatically utilize these comments when your strings are translated with our AI-powered service. By providing context such as:

  • Gender Specifications: Indicate if a word is masculine, feminine, or neutral.
  • Pluralization Rules: Specify if the string should account for singular and plural forms.
  • Cultural Nuances: Note any cultural references that need careful translation.

Our AI can generate more accurate and culturally appropriate translations, saving you time on revisions.

Additional Tips for Effective Localization

  • Consistent Terminology: Use the same terms for common functions throughout your app.
  • Avoid Hard-Coding Strings: Always use localized strings instead of hard-coded text.
  • Test Regularly: Regularly test your localized app versions to catch any issues early.

By taking advantage of Xcode’s comment features and integrating them with advanced AI translation services, you can simplify the localization process significantly. Not only does this approach save time, but it also enhances the quality of translations, leading to a better user experience globally.

Happy Coding!
