Xcode UI Languages

This repository keeps track of all the languages that can be selected in Xcode for a project’s localizations. Since Apple doesn’t provide a public, up-to-date list of these languages, this repo serves as a reference for developers who want to know which languages are available in Xcode’s UI.

Purpose

When you navigate in Xcode to:

Xcode > Project Navigator > Localizations

you can select from a list of supported languages for your project. This list is not documented anywhere publicly. This repository maintains that list in a structured format so it can be easily referenced or processed.

How It Works

1. The file xcode-ui-languages-list.txt contains all the language identifiers supported by Xcode.
2. The script generate.swift reads this list and outputs a formatted version:
   • By default, it outputs JSON (all-languages-formatted.txt) containing each language’s display name and identifier.
   • You can also output plain text for easy reading using the -t flag:

swift generate.swift -t

Whenever a new Xcode version is released, we have to manually add any new languages to xcode-ui-languages-list.txt and run the script again to update the formatted output.

Files

• xcode-ui-languages-list.txt – List of Xcode language identifiers (one per line).
• generate.swift – Swift script that reads the language list and generates a formatted output.
• all-languages-formatted.txt – Output generated by generate.swift (JSON or text).

Usage

Generate JSON output:

swift generate.swift

Generate plain text output:

swift generate.swift -t

Contribution

This repository is intended as a reference for developers looking to handle Xcode project localizations programmatically or for documentation purposes.
