If you want to update the VoiceOver user frequently about how a component is changing, when focused, you can use the .updatesFrequently accessibility trait. A downloading progress bar, a stock value, or a timer, are some examples.

Some of you have asked me how you can support what I do. This would really help, and would be hugely appreciated:
Find these posts useful? Share them at work, on social media, or with anyone that might find them interesting. Let's spread the word!
Check out any of my apps or games: Xarra!, RetroRapid!, or Mestre!.
A download and a review go a long way. They're free by default. On the App Store, ratings and reviews really help more people discover them.
Finding any of them useful? If so, and if you can afford it, purchasing lifetime access to all features or subscribing lets me buy the coffee that keeps me caffeinated. Caffeine keeps me going to maintain the apps, bring in new features that I hope you'll love, and keep writing.

If both screenChanged and layoutChanged notifications signal changes in the UI and allow you to move VoiceOver's focus somewhere else, what's the difference? To the user, screen changed plays a sound indicating them they got moved to a new screen.

Tip for abbreviations. Something like "3h 24m" will be read by VoiceOver as "3 h 24 meters". Formatters can help. DateComponentsFormatter with a "spellOut" units style will give you a more suitable label: "three hours, twenty-four minutes" Example code in the image: ```swift let dailyAverageLabel = UILabel() let abbreviatedReadableFormatter = DateComponentsFormatter() abbreviatedReadableFormatter.allowedUnits = [.hour, .minute] abbreviatedReadableFormatter.unitsStyle = .spellOut let abbreviatedReadableDuration = abbreviatedReadableFormatter.string(from: 12240) dailyAverageLabel.accessibilityLabel = abbreviatedReadableDuration ``` Some useful links: * Date Components Formatter: * Units Style: By the way! Formatters are also great for localisation.

Custom actions are also great for actions that are executed with a gesture that is overridden by VoiceOver. Think of the unread, flag and archive hidden options that you can make visible by swiping left/right on a message row in the Mail app.
