How to Localize Your SwiftUI App in 2025

If you're an iOS developer, making your app accessible to users around the world is more than just a nice-to-have—it's a competitive edge. But Xcode's built-in localization tools can feel manual, repetitive, and error-prone. In this post, we'll walk through how to effectively localize your SwiftUI app in 2025, and how Localizer Studio can save you hours in the process.

Why Localization Matters

Localization means adapting your app for different languages and regions. It improves accessibility, widens your user base, and aligns with App Store best practices for global reach.

Common examples:

• "Settings" in English → "Paramètres" in French
• Regional formats for dates and currencies
• Text direction (LTR vs RTL)

Traditional Swift Localization Workflow

1. Manually wrap strings with NSLocalizedString or LocalizedStringKey
2. Create .strings files for each language
3. Export/import these files to share with translators
4. Hope you didn’t miss a hard-coded string

This can work for small projects, but as your app grows, it becomes a burden.

Enter Localizer Studio 🚀

Localizer Studio is a macOS app built for Swift developers who care about clean code and fast iteration. It helps you:

• ✅ Automatically scan and extract localization keys from Swift files
• ✅ Organize keys by file or component
• ✅ Export .strings files for any target language
• ✅ Add context for translators
• ✅ See progress and avoid duplication

It works offline, runs locally, and integrates smoothly with your Xcode workflow.

Quick Start: Localizing with Localizer Studio

1. Download the app from the Mac App Store
2. Open your Xcode project in Localizer Studio
3. Choose which files/folders to scan
4. Export .strings files with one click
5. Send to your translator or import into your Xcode project

Bonus Tips

• Use SwiftGen alongside Localizer Studio for type-safe string management
• Add translator_comment support so your collaborators know the context
• Localize launch screen and system permissions too!

Final Thoughts

Localization doesn’t have to be a chore. With the right tooling, you can make your app accessible to millions more users—without sacrificing your time or code quality.
