This skill should be used when the user asks to "style with colors", "apply gradients", "use foregroundStyle", "add linear/radial gradient", "set tint color", or needs SwiftUI color and ShapeStyle API reference.

This skill should be used when the user asks to "add blur effect", "apply shadow", "adjust opacity/brightness", "use blend modes", "create visual effects", or needs SwiftUI visual effects API reference. Provides view modifiers (blur, shadow, opacity), VisualEffect protocol, blend modes, and Canvas drawing.

Use when writing, reviewing, or refactoring SwiftUI views. Covers state management, view composition, performance, modern APIs, navigation routing, sheet architecture, theming, haptics, deep links, loading states, and iOS 26+ patterns. Merged from swiftui-expert-skill with added UI architecture patterns from production apps (IceCubesApp).

This skill should be used when the user asks to "add material background", "apply translucent overlay", "use .regularMaterial", "choose material thickness", "work with shapes", or needs SwiftUI material and structure API reference. Provides material types (ultraThin to ultraThick), shapes (Rectangle, Capsule, Circle), and layout containers.

This skill should be used when the user asks to "set font", "use text styles", "apply font weight", "use custom fonts", "implement Dynamic Type", or needs SwiftUI typography API reference. Provides Font.TextStyle, Font.Design (serif, rounded, monospaced), Font.Weight, custom font usage, and ScaledMetric for adaptive sizing.

This skill should be used when the user asks to "add SF Symbols", "animate icons", "use symbol effects", "apply symbol rendering mode", "add bounce/pulse effect", or needs SwiftUI iconography API reference. Provides SF Symbols usage, rendering modes (monochrome, hierarchical, multicolor, palette), symbol effects, and variable values.

This skill should be used when the user asks to "present sheet", "show popover", "create alert", "add confirmation dialog", "configure presentation", or needs SwiftUI presentation API reference. Provides sheet, popover, fullScreenCover, alert, confirmation dialog, inspector modifiers, and macOS window behaviors.

Use when building UI with Apple's Liquid Glass material for iOS 26, iPadOS 26, macOS 26 - covers glassEffect, GlassEffectContainer, backgroundExtensionEffect, morph animations, toolbar grouping, button styles (.glass, .glassProminent), Icon Composer, ConcentricRectangle, scroll edge effects, and adoption best practices across SwiftUI, UIKit, and AppKit.
