IosReduceMotion [rule] v1.0.0

Disable or replace decorative animations with a simple crossfade when the Reduce Motion accessibility preference (UIAccessibility.isReduceMotionEnabled) is active.

Applies To

all iOS views with animations, transitions, or parallax effects

Examples

• SwiftUI: wrap decorative withAnimation calls in a guard !UIAccessibility.isReduceMotionEnabled.
• Custom transitions: swap slide/zoom for .opacity when Reduce Motion is on.
• Verify: enable Reduce Motion in Settings → Accessibility → Motion → Reduce Motion; all decorative movement must stop.

Rationale

Users with vestibular disorders enable Reduce Motion because animation causes dizziness or nausea. Ignoring this setting can cause physical discomfort. This is an accessibility requirement, not a preference.

Applies To

all iOS views with animations, transitions, or parallax effects
