How does it handle iPad multitasking?

It provides a decision tree for responding to container size instead of device orientation, ensuring your app looks great in 1/3, 1/2, or 2/3 Split View modes.

Is this skill compatible with older iOS versions?

While it favors modern APIs like onGeometryChange (iOS 16+), it provides best practices and constrained GeometryReader patterns for projects supporting older versions.

Does this skill support the new iOS 26 free-form windows?

Yes, it includes specific patterns and checklists for handling arbitrary window resizing, including removing UIRequiresFullScreen and using NavigationSplitView auto-adaptation.

Can it help with accessibility and Dynamic Type?

Absolutely. It includes specific patterns for adapting layouts based on dynamicTypeSize, such as automatically switching from HStack to VStack when accessibility font sizes are active.

Why should I use this over standard GeometryReader?

GeometryReader is 'greedy' and often disrupts sibling layouts; this skill promotes onGeometryChange and ViewThatFits for more stable, performant layouts that don't crush surrounding views.

Mobile Development

Implements modern, container-aware SwiftUI layouts that adapt seamlessly to different screen sizes, iPad multitasking, and free-form windows.

概要

This skill enforces a discipline of container-driven design for SwiftUI, moving away from fragile device-based assumptions. It provides expert guidance on selecting the optimal layout tools—such as ViewThatFits, AnyLayout, and the modern onGeometryChange—to ensure applications function correctly across all Apple platforms. By addressing specific challenges like iPad Split View, Stage Manager, and iOS 26 free-form windowing, it helps developers build future-proof interfaces that respond gracefully to available space rather than hardcoded device identities.
