I have two questions about reducing animations to increase accessibility.
1) What are the guidelines for animations with accessibility? I would think
that with VoiceOver on, you'd want to disable animations entirely, since
animations would be an entirely un-delightful delay to a blind user. How
about the "Reduce Motion" setting? What kinds of animations are
particularly problematic in what scenarios?
2) Technically, I was noticing that UIView.animate does not respect the
"Reduce Motion" setting. I was considering adding a wrapper:
public func animationDuration(_ duration: TimeInterval) -> TimeInterval {
return (UIAccessibilityIsReduceMotionEnabled() ||
UIAccessibilityIsVoiceOverRunning()) ? 0 : duration
}
Am I missing some built-in functionality, or is this the preferred solution?
Thanks!
