description

Official Xcode-grounded Apple development guidance for Swift, SwiftUI, UIKit, AppKit, WidgetKit, FoundationModels, AppIntents, Liquid Glass, Visual Intelligence, Xcode prompt behavior, and preview/code-edit workflows. Use when Codex needs to answer or edit Apple-platform code, generate or fix \#Preview blocks, interpret bundled Xcode Intelligence prompts/docs, or apply Apple-specific guidance from the selected Xcode and Apple system materials.

Apple Development Official

Use this skill for Apple-platform work where Xcode's own guidance matters more than generic advice: Swift-first app code, SwiftUI/UI framework questions, Liquid Glass, FoundationModels, AppIntents, previews, and Xcode agent behavior.

Load Order

1. Start with references/index.md to choose the right family of docs.
2. Use references/task-routing.md for the quick map from task type to reference file.
3. Load only the one or two flat runtime docs that match the task, usually a prompting-*.md file plus a platform-*.md file.
4. For Xcode assistant behavior, load references/prompting-core-rules.md, references/prompting-planner-executor-and-retrieval.md, and then the relevant assistant-*.md file.
5. For Apple framework and UI work, load the relevant platform-*.md file and add references/prompting-preview-and-playground-generation.md when the task asks for #Preview output.
6. Load references/system-intelligence-context-and-telemetry.md only when the task is about system availability, FoundationModels policy, or telemetry vocabulary.

Working Rules

• Prefer Swift, SwiftUI, UIKit, AppKit, WidgetKit, FoundationModels, AppIntents, and Apple APIs that ship on platform.
• Prefer Swift Concurrency and Swift Testing.
• Use #Preview for new SwiftUI previews.
• Prefer the bundled Apple and Xcode references before falling back to generic reasoning.
• Treat local Coding Assistant installation files as audit material, not runtime coding guidance.
• Preserve Apple platform names such as iOS, iPadOS, macOS, watchOS, and visionOS.
• Keep edits minimal unless the reference material clearly says otherwise.
• Do not load maintenance/ files during routine use.
