Claude Code skills for every Apple WWDC session — APIs, code examples, and migration guides from WWDC17 to WWDC25

This repository packages Apple WWDC session content as structured reference files for iOS/Swift developers. It works as a Claude Code skill you invoke from the CLI, and as a reference library you can drop into any Claude Code setup.

Installation

As an agentskills-compatible skill

This skill follows the agentskills open format. Install it into your skills directory:

# User-level (available in all projects)
git clone https://github.com/cruisediary/wwdc-skills ~/.agents/skills/wwdc-skills

# Or project-level
git clone https://github.com/cruisediary/wwdc-skills .agents/skills/wwdc-skills

Once installed, Claude Code will discover it automatically from the skill catalog.

As a Claude Code reference library

Clone or copy individual files from references/ into any project:

# Full library
git clone https://github.com/cruisediary/wwdc-skills

# Single file (self-contained, no dependencies)
curl -O https://raw.githubusercontent.com/cruisediary/wwdc-skills/main/references/canonical/swiftui.md

Usage

As a Claude Code skill

Add this skill to your Claude Code configuration, then ask questions naturally:

What's new in SwiftData?
Migrate my app from Combine to AsyncSequence
Show me WWDC23 Observation session
WWDC24-10179

SKILL.md is the entry point. It reads references/INDEX.md to locate the right reference file, then returns a focused answer in one of three shapes: code-first, guide-first, or migration (before/after).

As a reference library

Individual files in references/ can be copied into any project's .claude/skills/ or .claude/references/ directory. Each file is self-contained and works without the rest of this repo.

How it works

Five query modes (evaluated in priority order):

Session ID formats:

• WWDC17–19, WWDC25: 3-digit (e.g. WWDC17-602)
• WWDC20–24: 5-digit (e.g. WWDC24-10179)
• WWDC22: some 6-digit (e.g. WWDC22-110354)
