swiftui-whats-new-27 — Claude Code skill: what it does, how to install
A reference skill covering SwiftUI API updates across 2027 Apple platforms. It prevents build failures when @State transitions to a macro and guides migration.
npx skills add superagents-lab/xcode27-skills --skill swiftui-whats-new-27 -a claude-codeWhat swiftui-whats-new-27 does
This reference guide details framework modifications across the 2027 operating systems from Apple. When developers update their toolchains, coding models frequently select outdated parameter signatures from memory. The documentation directs the assistant to verified function signatures instead of speculative guesses.
Inside, separate guides describe container sorting with reorderable(), swipe gestures in scroll views via swipeActionsContainer(), and caching setups for AsyncImage. It also details ReadableDocument and WritableDocument implementations, which replace older document protocols.
Reordering stored property assignments inside an init method will cause bad runtime behavior. The guide forbids that shortcut and provides the correct migration path. tvOS 27 lacks support for container reordering and custom swipe areas.
What it helps with
- resolve build failures caused by the @State macro migration
- implement drag reordering on stacks or custom layouts
- enable swipe interactions inside generic scroll views
- assign custom network caching rules to AsyncImage requests
- migrate document workflows to the ReadableDocument protocol
Example prompts for the agent
- Help fix our view initialization after upgrading to the SDK 27 macro version of @State.
- How do I configure swipe interaction inside a ScrollView on iOS 27?
- Set up an AsyncImage instance with custom URLRequest caching options.
