Accessibility Skill

Applicability

• Platforms: iOS and Android
• React Native: 0.76+ (New Architecture interop assumed unless a checklist item says otherwise)

When to Use

• Building or reviewing any interactive UI
• Auditing a screen for screen-reader and assistive-technology support
• Verifying an app meets accessibility expectations before release

Guidance

Labels & Roles

• Every interactive element has an accessibilityLabel that describes its purpose, not its type
• Every interactive element has an accessibilityRole (button, link, header, etc.)
• State changes use accessibilityState (disabled, selected, expanded)
• Images have an accessibilityLabel, or are marked accessibilityElementsHidden if decorative
• Dynamic content changes are announced (AccessibilityInfo.announceForAccessibility)

Incorrect:

<TouchableOpacity onPress={onDelete}>
  <Icon name="trash" />
</TouchableOpacity>

Correct:

<TouchableOpacity
  onPress={onDelete}
  accessibilityLabel="Delete item"
  accessibilityRole="button"
  hitSlop={{ top: 10, bottom: 10, left: 10, right: 10 }}
>
  <Icon name="trash" />
</TouchableOpacity>

Touch & Focus

• Touch targets are at least 44x44pt
• Focus order is logical (top to bottom, left to right)

Visual

• Colour is not the only indicator of state (add icon, text, or pattern)
• Text scales with the system font-size preference

Verification

• Tested with VoiceOver (iOS) and TalkBack (Android)

Pitfalls

• Labels that describe the element type ("button") instead of its purpose ("Delete item") give screen-reader users no useful information.
• Forgetting accessibilityState={{ disabled: true }} on a disabled control means the screen reader still announces it as an active button.
• Relying on colour alone (e.g. red for error) excludes colour-blind users; pair it with an icon or text.
• Fixed font sizes break layouts when users increase system text size — test at large dynamic type settings.
