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:

   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):

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.
