I'm working on improving accessibility in a native macOS app and going through WCAG, but with so many success criteria it's hard to know where to focus for native Apple platform apps.
1. Does Apple recommend a specific subset or checklist of WCAG requirements for macOS and iOS?
2. If not, which criteria are generally considered essential, and how do developers typically validate them using Apple's accessibility tools and assistive technologies?
I'm looking for a prioritized list of criteria that actually apply to native apps, rather than trying to implement every WCAG criterion individually.
WCAG checklist does not map directly to native apps. The first thing to do is to run the audit function in Accessibility Inspector (Xcode > Open Developer Tool). Then try to use something like VoiceOver to navigate the content of your app. See if you can reach all the UI and hear user friendly description for each UI.
