apple-dev-skills

Overview

apple-dev-skills is a Claude Code plugin marketplace for independent developers and small teams building a new app on iOS 26 and macOS 26, from idea through to App Store release. It has two halves: Apple and Swift skills for the app itself, and collaboration skills (the author calls this harness engineering) for directing the agents that build it. Skills trigger on their own once installed.

Features

• 26 Apple and Swift skills, such as Swift 6 concurrency, platform targets, SwiftPM modularisation and a Swift Testing baseline
• 12 collaboration skills for spec writing, sub-agent handoffs, review cycles and conflict detection
• Links to 7 external skills from other authors, credited and installed from their own repos
• Can be pinned to a release tag for a team in .claude/settings.json
• README available in English, Traditional Chinese, Simplified Chinese and Japanese

Requirements

• Claude Code for the plugin install
• Skills assume an iOS 26 / macOS 26 floor and Xcode 26.x by default
