Applies and reviews Liquid Glass in SwiftUI apps: decides which views should get the material and which should not, uses glassEffect, GlassEffectContainer, glass button styles and morphing transitions correctly, cleans up bars and backgrounds that fight the system look, and adds fallbacks for OS versions before 26. Use when the user says "adopt Liquid Glass", "update the app for iOS 26 design", "add a glass effect to this view", "make this button glass", "review my Liquid Glass usage", "glassEffect is not morphing", or asks how to keep the app building for iOS 18 while using the new material.
