SwiftUI Layout Reference

Acerca de

This skill serves as a technical companion for developers building for Apple platforms, offering a deep dive into the SwiftUI layout engine. It bridges the gap between basic views and complex, adaptive interfaces by providing syntax and usage patterns for advanced APIs like ViewThatFits, AnyLayout, and the custom Layout protocol. It specifically focuses on modern development techniques, including performant geometry reading and proper safe area handling, helping developers build robust UI that works across iOS, iPadOS, macOS, and visionOS while avoiding common performance pitfalls like layout loops.

Características Principales

• Detailed comparison and best practices for .padding() versus .safeAreaPadding()
• Reference for platform-specific adaptations using size classes and window APIs
• Comprehensive guidance on adaptive containers like ViewThatFits and AnyLayout
• Performance-focused geometry reading using onGeometryChange and GeometryReader
