There is an accessibility trait for defining something that represents a custom keyboard's key: .keyboardKey. It allows VoiceOver users to change the typing mode to Direct touch typing. The calculator app or an access pin pad, 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.

When something is focused with VoiceOver, if you double tap on the screen, it will be like interacting with the centre of the focused element. If you need to change that, you can customise the accessibilityActivationPoint. https://developer.apple.com/documentation/objectivec/nsobject-swift.class/accessibilityactivationpoint
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.
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()
