Last active May 1, 2022 17:32

This helps you to run an optional animation depending on a condition without needing to put your conditional logic inside your withAnimation closure. In this example we support Reduce Motion Accessibility

	// MARK: GLOBAL FUNCTION
	func withOptionalAnimation<Result>(_ animation: Animation? = .default, _ body: () throws -> Result) rethrows -> Result {
	// Evaluate the parameter you want to check: ReduceMotion in this case
	if UIAccessibility.isReduceMotionEnabled {
	// The body gets executed without animation
	return try body()
	} else {
	// The body gets executed with animation
