SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

SwiftUI animation guidance that helps developers implement smooth, performant, and accessible animations following Apple's best practices across implicit, explicit, transitions, gestures, and modern iOS 17 APIs like PhaseAnimator and KeyframeAnimator.

Core Features & Use Cases

  • Implicit animations with withAnimation and .animation modifier
  • Explicit animations using Animatable and AnimatableModifier
  • Transition techniques (built-in, asymmetric, custom)
  • Gesture-driven animations and interactive springs
  • Modern APIs iOS 17: PhaseAnimator and KeyframeAnimator

Quick Start

Toggle a state to trigger a smooth SwiftUI animation on a view using withAnimation.

Frequently Asked Questions about swiftui-animations

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

FAQPage Schema
How do I create smooth SwiftUI animations using withAnimation?▼

Use withAnimation to wrap state changes and trigger implicit SwiftUI animations. Toggle a state value inside the closure to smoothly transition view properties like opacity or scale.

Does SwiftUI support custom transitions and AnimatableModifier for complex animations?▼

Yes, SwiftUI supports custom transitions and AnimatableModifier to animate complex view properties. You can use built-in, asymmetric, or custom transitions alongside explicit animation techniques.

How do KeyframeAnimator and PhaseAnimator work in iOS 17?▼

KeyframeAnimator and PhaseAnimator are modern iOS 17 SwiftUI APIs. PhaseAnimator cycles views through defined phases, while KeyframeAnimator interpolates values across keyframes for intricate animations.

What's the best way to handle gesture-driven animations and interactive springs in SwiftUI?▼

Handle gesture-driven SwiftUI animations by attaching gesture modifiers to views and using interactive springs. This allows animations to respond dynamically to user input like drags and taps.

Can I make SwiftUI animations accessible for reduced motion preferences?▼

Yes, SwiftUI animations can be made accessible by respecting reduced motion preferences. The Skill provides guidance on accessibility considerations to ensure animations adapt to user settings.

Why does my SwiftUI animation not work when using the .animation modifier?▼

SwiftUI animation issues with the .animation modifier often occur when state changes are not properly linked. Use withAnimation for explicit control or ensure the modifier depends on the correct state value.
