SwiftUI has equivalent accessibility modifiers for some of UIAccessibility's properties in UIKit. Same basic concepts apply.
Label: https://developer.apple.com/documentation/swiftui/view/accessibilitylabel(:)-9ek2h
Value: https://developer.apple.com/documentation/swiftui/view/accessibilityvalue(:)-8esl7
Traits: https://developer.apple.com/documentation/swiftui/view/accessibilityaddtraits(:)
Hint: https://developer.apple.com/documentation/swiftui/view/accessibilityhint(:)-3i2vu
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.
With regular buttons from UIKit or SwiftUI, you are all set. With complex views, headings, or table/collection view cells that, when selected, bring the user somewhere else in the app or perform an action, you'll have to add the button trait.
UIAccessibility is the cornerstone of any accessible UIKit app. Among others, understanding what an accessibility label, value, trait or hint are, is key. This is an example of how they could be configured for a custom rating component.
In UIKit, to create an adjustable component we need to add the adjustable trait and override both accessibilityIncrement() and accessibilityDecrement(). In SwiftUI, everything you need is bundled in the accessibilityAdjustableAction(_:) modifier.
