Does this skill support the latest iOS versions?

Yes, it includes references for modern APIs like onGeometryChange (iOS 16+), safe area padding (iOS 17+), and upcoming iOS 26 window management features.

Why use onGeometryChange instead of GeometryReader?

onGeometryChange is preferred because it reads geometry after the layout phase without the 'greedy' space-filling behavior of GeometryReader, which helps prevent layout loops and performance issues.

What is the axiom-swiftui-layout-ref skill?

It is a specialized technical reference guide for Claude Code that provides documentation, implementation patterns, and code snippets for modern SwiftUI layout APIs.

Does this cover visionOS development?

Yes, the layout principles, adaptive patterns, and safe area guidelines covered in this skill are directly applicable to visionOS, as well as iOS, iPadOS, and macOS.

How is this different from the axiom-swiftui-layout skill?

This skill acts as a technical API reference, while axiom-swiftui-layout provides higher-level decision guidance, architectural advice, and anti-patterns.

Mobile Development

Provides a comprehensive API guide for building adaptive, modern user interfaces using SwiftUI layout tools and protocols.

소개

This reference skill equips developers with deep technical knowledge of the SwiftUI layout system, covering everything from basic adaptive containers to complex custom layout protocols. It serves as an essential companion for building responsive xOS applications, offering precise implementation patterns for ViewThatFits, AnyLayout, and the latest safe area APIs. By providing immediate access to syntax and best practices for geometry reading and window management, it streamlines the development of pixel-perfect interfaces across iOS, iPadOS, and visionOS while helping avoid common layout-phase performance pitfalls.
