SwiftUI Adaptive Layout

Overview

Discipline-enforcing skill for building layouts that respond to available space rather than device assumptions. Covers tool selection, size class limitations, iOS 26 free-form windows, and common anti-patterns.

Core principle: Your layout should work correctly if Apple ships a new device tomorrow, or if iPadOS adds a new multitasking mode next year. Respond to your container, not your assumptions about the device.

When to Use This Skill

• "How do I make this layout work on iPad and iPhone?"
• "Should I use GeometryReader or ViewThatFits?"
• "My layout breaks in Split View / Stage Manager"
• "Size classes aren't giving me what I need"
• "Designer wants different layout for portrait vs landscape"
• "Preparing app for iOS 26 window resizing"
