XCDocs

XCDocs lets your agents quickly search local Apple docs without keeping Xcode open!

It uses the vector database powering Xcode's DocumentationSearch MCP tool under the hood, which is already on your Mac.

Includes:

• xcdocs CLI & agent skill, designed for use by agents like Codex or Claude Code
• Swift package, to integrate XCDocs into other tools

Availability

• macOS 26+
• Apple silicon only
• Xcode 26.3 RC or above has to be installed, but you don't need Xcode open.

Install

Ask your agent to help!

Recommended

Install with Homebrew:

brew install BitrigApp/tap/xcdocs

Alternative

Download the CLI from Releases and put it in /usr/local/bin. You can also clone the repo and run swift build yourself. The resulting binary will be in .build/debug/xcdocs.

Agent Skill

• Codex: Tell agent to copy/symlink .agents/skills/xcdocs to ~/.agents/skills/xcdocs
• Claude Code: Tell agent to copy/symlink .agents/skills/xcdocs to ~/.claude/skills/xcdocs

Usage

xcdocs --help

Search for documentation:

xcdocs search "swift testing"
xcdocs search "swift testing" --framework "Swift Testing" --limit 5
xcdocs search "swift testing" --kind article --limit 5
xcdocs search "swiftui color" --json
xcdocs search "swiftui color" --omit-content

Get an entry by identifier:

xcdocs get /documentation/Testing
xcdocs get /documentation/Testing --json

Swift API

XCDocs also exposes a Swift package which you can integrate into other tools.

To get started, add the repo to your Package.swift.

import XCDocs

let client = Client()

let searchResults = try await client.search(
    "swift testing",
    frameworks: ["Swift Testing"],
    kinds: [.article],
    limit: 5,
    omitContent: false
)

let entry = try await client.entry(
    for: "/documentation/Testing"
)

Development

Run tests:

swift test

Run formatting checks:

swift format lint --strict Package.swift
swift format lint --strict --recursive Sources Tests
