## Description

Every Apple framework, indexed locally, with deprecation analysis and an MCP server no other Apple-docs tool has. Trigger phrases: `look up an Apple API`, `what's deprecated in iOS`, `find a SwiftUI symbol`, `port this from UIKit to SwiftUI`, `what changed at WWDC`, `use apple-docs`, `run apple-docs-pp-cli`.

# Apple Developer Documentation, Printing Press CLI

## Prerequisites: Install the CLI

This skill drives the `apple-docs-pp-cli` binary. **You must verify the CLI is installed before invoking any command from this skill.** If it is missing, install it first:

1. Install via the Printing Press installer. It defaults binaries to `$HOME/.local/bin` on macOS/Linux and `%LOCALAPPDATA%\Programs\PrintingPress\bin` on Windows:
   ```bash
   npx -y @mvanhorn/printing-press-library install apple-docs --cli-only
   ```
2. Verify: `apple-docs-pp-cli --version`
3. Ensure the reported install directory is on `$PATH` for the agent/runtime that will invoke this skill.

If the `npx` install fails (no Node, offline, etc.), fall back to a direct Go install (requires Go 1.26.6 or newer):

```bash
go install github.com/mvanhorn/printing-press-library/library/developer-tools/apple-docs/cmd/apple-docs-pp-cli@latest
```

If `--version` reports "command not found" after install, the runtime cannot see the binary directory on `$PATH`. Do not proceed with skill commands until verification succeeds.

## When to Use This CLI

Reach for this CLI when you need to read Apple's docs from a terminal, when an agent is grounding Swift code generation against current Apple APIs, when planning a platform migration (iPad → visionOS, AppKit → SwiftUI), or when authoring a 'what's deprecated in iOS N' guide. The local SQLite store unlocks queries, cross-framework grep, snapshot diff, deprecation cliff, that no online docs viewer offers.
