A comprehensive reference for SwiftUI animations covering the full iOS 17+ API surface, from basic withAnimation to KeyframeAnimator and PhaseAnimator. The triage workflow at the top is genuinely helpful for choosing between eight different animation approaches, and the spring presets (smooth, snappy, bouncy) get proper explanations with duration and bounce parameters. What stands out is the accessibility coverage, every section reminds you to test with Reduce Motion, and the review checklist makes it hard to ship jittery animations. The KeyframeAnimator examples show actual multi-property choreography, not just scale effects. If you're doing anything beyond fade-ins, the matchedGeometryEffect and navigation zoom sections will save you from fighting the layout system.
