Apple UI Animation and Graphics

Choose the simplest rendering system that expresses the motion, then make accessibility and lifecycle behavior part of the design rather than a later patch.

Compatibility baseline

• Canvas and TimelineView require iOS 15, macOS 12, tvOS 15, or watchOS 8.
• matchedGeometryEffect requires iOS 14 / macOS 11.
• PhaseAnimator, KeyframeAnimator, and the first symbol-effect APIs require iOS 17 / macOS 14.
• Zoom navigation transitions and SwiftUI animation bridging into UIKit/AppKit require iOS 18 / macOS 15 where documented.
• Lottie’s native SwiftUI LottieView was introduced in Lottie 4.3. Pin a tested package version and obey that release’s Xcode, Swift, and deployment requirements; Lottie 4.6 requires Xcode 16 / Swift 6.
• Gate newer APIs with #available and provide a meaningful lower-target result. Treat 27-cycle APIs as unavailable unless the project actually builds with that SDK.

State the exact minimum that the proposed implementation needs; do not assign one minimum to every animation technique.
