Apple Documentation Access

Router skill providing direct access to Apple's official for-LLM markdown documentation bundled inside Xcode.

Use this skill when you want Apple-authored guidance from the Xcode-bundled Apple docs that MCP can expose at runtime, rather than only repo-authored summaries.

When to Use

• You need the exact API signature or behavior from Apple.
• A Swift compiler diagnostic needs explanation with examples.
• Another Apple Text skill references an Apple framework and you want the official source.
• You want authoritative code examples for AttributedString, styled TextEditor, toolbar behavior, or related text-system changes that ship in Xcode docs.

Priority: Apple Text skills provide opinionated guidance and project-specific tradeoffs. Apple docs provide authoritative API detail. Use both together.

Quick Decision

• Need opinionated guidance, not Apple's exact wording -> use the relevant Apple Text skill directly
• Need symptom-first debugging -> /skill apple-text-textkit-diag
• Need Apple-authored API detail or Swift diagnostic explanation -> stay here

Example Prompts

• "What does Apple's AttributedString update doc say about the newest Foundation text changes?"
• "Show me Apple's official guidance for styled TextEditor editing."
• "What does the Swift diagnostic actor-isolated-call mean?"
• "What Apple-authored docs ship in Xcode for text and editor-adjacent APIs?"

What's Covered

Apple Guide Topics

• AttributedString updates and Foundation text changes.
• SwiftUI styled text editing behavior.
• Toolbar features near editing and text-centric UI.
• The checked-in sidecar index at xcode-docs-index.md listing the local Apple-text subset and the bundled Swift diagnostics catalog.

Swift Compiler Diagnostics

• Official explanations with examples for Swift diagnostics bundled in the Xcode toolchain.
• Especially useful when concurrency or type-system diagnostics intersect with text code and editor integrations.

How It Works

Apple bundles for-LLM markdown documentation inside Xcode at two locations:

• AdditionalDocumentation for framework guides and implementation patterns.
• Swift diagnostics for compiler error and warning explanations with examples.

Apple Text can read these files at runtime from the local Xcode installation when APPLE_TEXT_APPLE_DOCS=true.

When runtime Apple docs are enabled in the current client, use them first. Treat the checked-in sidecars in this skill as the repo-backed fallback and the fastest local subset for Apple text questions.

Configuration

Variable	Default	Purpose
APPLE_TEXT_XCODE_PATH	/Applications/Xcode.app	Custom Xcode path, such as Xcode-beta.app
APPLE_TEXT_APPLE_DOCS	false	Set to true to enable runtime loading of Apple-authored markdown docs from the local Xcode install

• Use /skill apple-text-attributed-string for AttributedString vs NSAttributedString decisions and conversion strategy.
• Use /skill apple-text-writing-tools when the real problem is Writing Tools integration, not Apple-doc lookup.
• Use /skill apple-text-foundation-ref for broader Foundation text utilities beyond the Xcode-bundled subset.
