This lesson is part of Swift · All levels
Summary
This lesson reviews the principles and implementation of Accessibility on iOS apps using SwiftUI. Building an accessible app ensures that everyone, including users with visual, motor, or hearing disabilities, can interact comfortably through assistive features such as VoiceOver, Dynamic Type, and High Contrast.
Key points
- VoiceOver reads the screen content contextually using special gestures
- Modifier .accessibilityLabel() provides a sound description for a visual element or an icon without text
- The modifier .accessibilityHint() provides instructions regarding the results of a user action
- Dynamic Type support ensures that the text size of the app can adjust user readability preferences
