Tips and tricks to build accessible iOS apps

Accessibility labels should not contain the type of the control, that's a job for the accessibility trait instead. If you have a button with a label like "Close button" and the ".button" trait, VoiceOver will say: "Close button, button".

Good accessibility labels are at the core of good accessible apps. It should be a localized succinct string that tells as much as possible about the component (without including its type) and provides context avoiding verbosity and redundancy.

SwiftUI has equivalent accessibility modifiers for some of UIAccessibility's properties in UIKit. Same basic concepts apply.

UIAccessibility is the cornerstone of any accessible UIKit app. Among others, understanding what an accessibility label, value, trait or hint are, is key. This is an example of how they could be configured for a custom rating component. #GAAD2022
