README

iOS & macOS 26 Skills for Claude Code

**8 production-grade Claude Code skills for building world-class iOS 26 / macOS Tahoe apps.**

Verified against Apple's WWDC 2025 docs + Xcode 26.3 (latest as of March 2026) by a swarm of AI (Claude Opus 4.6 + GPT-5.4 Codex + Gemini 3.1 Pro). Current through iOS 26.4 RC / macOS 26.4 RC (March 18, 2026).

Why These Exist

Most "SwiftUI skills" floating around have hallucinated APIs. We caught these in the wild:

.prominent listed as a Glass variant (doesn't exist — only .regular, .clear, .identity)
ObservableObject recommended over @Observable (deprecated pattern)
Missing 10+ iOS 26 APIs that shipped after training cutoffs

These skills were cross-verified by 3 independent AI models against Apple's ac
