VoiceOver focus must move to the alert when displayed and back to the trigger button when the alert is closed.
Use .alert() to code a native SwiftUI alert that receives VoiceOver focus when opened.
Use AccessibilityFocusState to send focus back to the trigger button that opened the alert when the alert is closed.
Platform Defects:
- Alert button text does not have sufficient contrast ratios.
- Alerts will not automatically send focus back to the trigger button and this could be considered an accessibility defect in Apple's native
.alert()component in which case bugs should be filed with Apple. - Native SwiftUI Alerts will not have their heading text spoken as a Heading to VoiceOver users and this could be considered an accessibility defect in Apple's native
.alert()component in which case bugs should be filed with Apple.
