Accessibility in SwiftUI - Friday

Session materials: https://developer.apple.com/videos/play/wwdc2019/238/

• Make your app usable by all of your customers

Automatic Accessibility with SwiftUI

• SwiftUI makes items accessible automatically for some elements like Text() and generates accessibility elements

SwiftUI Accessibility API

SomeView()
.accessibility(label: Text())
.accessibility(value: Text())
.accessibilityAction(named: Text()) {
  clear()
}

Understandable

• Do the displayed strings provide enough information? .accessibility(visibilty: .hidden) to exclude unnecessary items from accessibility
• Provide context by adding labels, values and hints

Interactable

• Does a custom action simplify the interaction?
• Simplify by adding custom actions

Navigable

• Can you speed up navigation?
  • Give specific headers to focus the user onto key areas
• Speed up elements by grouping

Evaluating Accessibility

• Use your app with
  • VoiceOver
  • Full keyboard access
  • Voice control
• Use accessibility inspector: explore, test and debug your app's accessibility
