Information for Developers on how to Build Accessible iOS, iPadOS, Mac, Apple Watch, and Apple TV Apps

Apple products offer a range of built-in vision accessibility features such as VoiceOver, Zoom, and braille Screen Input. Information on the full range of vision features across all Apple's platforms is available on their accessibility portal.

VoiceOver is a text to speech screen reader that enables people to experience the interface on their devices without having to see the screen. People who are blind depend on VoiceOver to provide auditory feedback while using their macOS, iOS, iPadOS, watchOS, and tvOS devices.

Often with only a few steps, an app can be made VoiceOver-accessible in Xcode or programmatically. By increasing accessibility, developers open their app to a wider audience, and make it easier for everyone to use.

Apple provides a guide for developers on how to make their applications accessible:
