SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill eliminates the frustration of implementing inconsistent, inaccessible, or poorly performing animations in macOS SwiftUI apps, which often fail to match platform design conventions or meet accessibility requirements.

Core Features & Use Cases

  • Comprehensive API Coverage: Guides use of all core SwiftUI animation tools for macOS, including withAnimation, Animation presets, matchedGeometryEffect, PhaseAnimator, KeyframeAnimator, and view transitions.
  • macOS-Specific Guidance: Provides platform-aligned spring tuning, window/sheet transition behavior notes, and AppKit interop patterns for animated NSViewRepresentable views.
  • Accessibility & Performance Best Practices: Includes reduced motion fallback patterns, performance optimization tips, and common mistake avoidance to ensure animations are inclusive and smooth.
  • Reusable Patterns: Offers ready-to-use code patterns for common macOS UI animations like sidebar-to-detail hero transitions, loading states, and complex multi-step keyframe animations.
  • Use Case Example: A developer building a macOS productivity app can use this Skill to implement a smooth, accessible sidebar-to-detail hero transition, snappy toggle animations, and compliant reduced motion behavior without manual trial and error.

Quick Start

Use the swiftui-macos-animation skill to add an accessible, smooth sidebar-to-detail hero transition to your macOS SwiftUI app's NavigationSplitView.

Frequently Asked Questions about swiftui-macos-animation

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I implement a matchedGeometryEffect hero transition in a macOS SwiftUI NavigationSplitView?▼

Implement a matchedGeometryEffect hero transition in macOS SwiftUI by applying the modifier with a shared namespace to synchronize source and destination views within your NavigationSplitView. This Skill provides reusable patterns for smooth sidebar-to-detail transitions, ensuring proper alignment and platform-consistent animation behavior.

Does SwiftUI PhaseAnimator work for creating loading state animations on macOS?▼

PhaseAnimator works for creating loading state animations on macOS by cycling through predefined phases to drive sequential view changes automatically. This Skill demonstrates how to leverage PhaseAnimator for smooth loading states, mapping phase transitions to view modifiers for continuous, platform-aligned motion.

What are the best spring tuning parameters for macOS SwiftUI animations?▼

The best spring tuning parameters for macOS SwiftUI animations align with platform conventions by using specific response and damping values that match native macOS behaviors. This Skill provides macOS-specific spring tuning guidance to ensure your withAnimation calls feel snappy and integrated.

Why does my SwiftUI animation perform poorly when presenting sheets on macOS?▼

Your SwiftUI animation may perform poorly when presenting sheets on macOS due to unoptimized matchedGeometryEffect usage or conflicting window transition behaviors. This Skill provides performance optimization tips and macOS-specific window presentation guidance to ensure smooth transitions.
