Swiftui Whats New 27

Apple's guide to SwiftUI changes in the 2027 OS releases (iOS 27, macOS 27, watchOS 27, tvOS 27, visionOS 27). Use when a view using @State stops compiling after an SDK update with errors like 'used before being initialized', 'invalid redeclaration of synthesized property', or 'extraneous argument label' (@State became a macro in SDK 27 and the obvious init-reordering fix is wrong — consult this skill first); when adding drag-to-reorder to any container via reorderable()/reorderContainer or its drag-and-drop integration; when working with AsyncImage caching or AsyncImage(request:); when controlling toolbar overflow (visibilityPriority, ToolbarOverflowMenu, topBarPinnedTrailing, toolbarMinimizeBehavior); when presenting alert or confirmationDialog from an optional item binding; when adding swipe actions outside List via swipeActionsContainer; when building document apps with ReadableDocument/WritableDocument; for @ContentBuilder result-builder source breaks; or when asked what's new in SwiftUI.

File contents

swiftui-whats-new-27 (stub)

Not yet extracted. This is a stub. The real skill is Apple-authored content that ships inside Xcode; Apple's license doesn't permit redistributing it, so this kit extracts it from YOUR Xcode instead.

To install the real content (requires Xcode 27+, ~5 seconds), run the extraction script that ships alongside these skills. Relative to this skill's own directory it is at:
../apple-api-updates/scripts/extract-apple-skills.sh
(In the Claude Code plugin layout it is also exposed at the plugin root as scripts/extract-apple-skills.sh. If apple-api-updates is not installed alongside, install it — the script ships inside it.)

If you are an agent reading this: resolve this SKILL.md's path and run that script with your shell tool. Skill bodies are cached for the session and you cannot run /reload-plugins yourself (it's a user command), so after extracting: answer the current request by reading the extracted SKILL.md and its references/ directly from disk (plain markdown, fully usable), and ask the user to run /reload-plugins — or start a new session — so future invocations serve the real content.
