UISliders are adjustable, and its default accessibility value is represented in percentages. But that's not always the best format to express a value. Consider a slider to select a distance radius. Miles or km seem a more appropriate unit.
override var accessibilityValue: String? {
get {
let formatter = MeasurementFormatter()
let measurement = Measurement(
value: Double(value),
unit: .kilometers
)
formatter.unitStyle = .long
return formatter.string(from: measurement)
}
set {}

With VoiceOver, you can swipe up/down to increase/decrease the value of adjustable components. You need to implement accessibilityIncrement() and accessibilityDecrement() accordingly, and configure an accessibility value that makes sense. Example code in the image: ```swift override func accessibilityIncrement() { guard value < 5 else { return } value += 1 accessibilityValue = "\(value) of 5" sendActions(for: .valueChanged) } override func accessibilityDecrement() { guard value > 1 else { return } value -= 1 accessibilityValue = "\(value) of 5" sendActions(for: .valueChanged) } ``` Links to the official documentation: * accessibilityincrement() * accessibilitydecrement()
With the Accessibility Inspector you can check the value for the most common accessibility attributes for individual elements, do some basic navigation, and even perform actions if the component is adjustable or if it has custom actions.
Configuring the header accessibility trait, when appropriate, is one of my favourite accessibility quick wins. In this example, you need a single swipe down, instead of 12 swipes to the right to get to from Podcasts to Artists, in the app.
