Apple HIG — Motion
Apple Human Interface Guidelines motion page covering responsiveness, continuity, platform convention, and respect for Reduce Motion. It defines motion as purposeful, platform-appropriate, and responsive to accessibility preferences; the guidance is version-sensitive.

What this source teaches
- Bind platform-specific Apple motion guidance to AwesomeDS motion contracts: responsiveness (immediate feedback), continuity (spatial awareness), and Reduce Motion compliance must all be testable.
- Never copy Apple choreography as a cross-platform default; extract the intent model (motion = navigation orientation + state communication + delight) and apply it to AwesomeDS motion tokens.
- Test reduced-motion alternatives as first-class paths, not afterthoughts.
Where AwesomeDS applied it
rule.adaptation.capability-first— Adapt by capability, not device labelrule.motion.purpose-first— Motion communicates state, not decoration
Implementations and artifacts
No directly linked artifacts.
Caveats & anti-imitation
Transfer motion intent model and Reduce Motion contract; do not copy Apple spring physics parameters or choreography as cross-platform defaults.
