Localization Translator
macOS Native App
Requirements
Drag & Drop
Simply drag your .xcloc folders or .xliff files into the app. No complex setup required.
100+ Languages
Powered by Google Translate API for accurate translations in over 100 languages.
Placeholder Safety
Automatically preserves %@, %d, {0} and other placeholders in your localized strings.
Real-time Progress
Watch translation progress and detailed logs in real-time as files are processed.
How It Works
Drag & Drop Files
Drag your Xcode localization folders (.xcloc) or XLIFF files (.xliff) into the app window. The app automatically detects the file type and prepares for translation.
Automatic Processing
The SwiftUI interface communicates with a Python bridge service that extracts localization strings and identifies placeholders to preserve.
Smart Translation
Text content is sent to Google Translate API while placeholders are protected. The translation engine processes XLIFF files using the deep-translator library.
Real-time Results
Translated content is written back to your files locally. Progress and detailed logs are displayed in real-time within the app.
Technical Architecture
SwiftUI Interface
Beautiful native macOS interface built with SwiftUI. Supports drag-and-drop, real-time logs, and system integration.
Python Bridge
Swift communicates with Python 3.7+ through TranslationService.swift for processing localization files and API calls.
Translation Engine
Uses deep-translator library to process XLIFF files and Google Translate API for accurate translations in 100+ languages.

Frequently Asked Questions
Does the app work offline?
An internet connection is required for translation as the app uses Google Translate API. However, all file processing happens locally on your Mac. No files are uploaded to any server.
Are my translation files stored anywhere?
No. All files are processed locally on your device. Only the text content is sent to Google Translate for translation. We do not store, retain, or have access to any of your data. See our Privacy Policy for details.
What file formats are supported?
The app supports Xcode localization folders (.xcloc) and XLIFF translation files (.xliff). Simply drag and drop them into the app window to begin translation.
Will placeholders be preserved in translations?
Yes! The app automatically detects and preserves all placeholders including %@, %d, %ld,{0}, {1}, and other format specifiers. This ensures your localized strings work correctly with dynamic content in your app.
How accurate are the translations?
The app uses Google Translate API, which provides high-quality translations for over 100 languages. However, we recommend reviewing automated translations for context, tone, and cultural appropriateness, especially for user-facing content in your apps.
Can I use this for commercial projects?
Yes! The app is designed for developers working on iOS, macOS, and other Apple platform apps. You can use it for personal projects, client work, and commercial applications. However, please note that Google Translate API usage is subject to their terms of service.
