Target Platform

These skills intentionally target the latest Apple APIs and platform conventions.

Why bleeding edge? LLMs already have plenty of legacy Apple APIs in their training data — when a project needs backward compatibility, agents can add it on their own. But for the newest APIs, agents need to be steered with up-to-date docs; without them, they'll hallucinate or fall back to deprecated patterns.

iOS 26+ / Swift 6 — no legacy patterns. Uses:

@Observable macro (not ObservableObject)
NavigationStack (not NavigationView)
Swift concurrency (async/await, not completion handlers)
Liquid Glass design system
Swift Testing where applicable
