FAST APP LOCALIZATION FOR XCODE
–––––––————
Xlocalize is the fastest way to translate String Catalog (.xcstrings) files, localize macOS and iOS apps, and reach global users. Built natively for macOS and focused on Xcode 15+, it delivers instant, reliable, developer-grade localization with one click. Ship multilingual apps, eliminate manual copy-paste, and keep every Xcode localization perfectly in sync.
–––––––————
KEY FEATURES
–––––––————
• One-click translation of a single key, an entire language, or every language at once
• Dedicated support for String Catalog / xcstrings, plurals, placeholders, Markdown, HTML
• Status management for each key: new, translated, don’t translate
• Inline comments to give translators full context and improve accuracy
• Undo / Redo for every action—work fearlessly and roll back any change
• Blazing-fast search, filter, and replace across keys, languages, and statuses
• Bulk copy: duplicate translations from one language to another in seconds
–––––––————
SIMPLE, FOCUSED WORKFLOW
–––––––————
Open your project, drop your .xcstrings file, and press Translate. Xlocalize scans keys, preserves SwiftUI and Objective-C placeholders, and highlights missing strings—all in a lightweight interface that keeps focus on code, not configuration.
–––––––————
MADE FOR DEVELOPERS
