The Xliff Tool for Xcode (often just called Xliff Tool) is a translation utility crafted for developers. It facilitates the editing of xliff and xcloc file formats.

The Xliff Tool leverages AI for translations. You have the option to utilize Apple's integrated ML translation services or opt for a local or online LLM translation service. Furthermore, the most recent iteration of the Xliff Tool also boasts the ability to scrutinize the grammar of text and offer constructive feedback for revisions.

Notably, the Xliff Tool enhances translation precision through cross-verification, a feature that proves particularly useful even for those without prior knowledge of the target language.

It is highly advisable to consult the "Best Practices" guide before delving into the Xliff Tool. This guide, which is a compilation of insights and techniques by developers for using the Xliff Tool, can significantly enhance your translation workflow. The "Best Practices" guide is easily identifiable within the Xliff Tool by its distinct yellow book icon.

For your convenience, you can also access and read the "Best Practices" guide online, located at the top of this website's homepage.
