Hi, I have an app that displays lines of text, that I want to make accessible with VoiceOver. It's based on a UITextView.
I have implemented the UIAccessibilityReadingContent protocol, following the instructions in https://developer.apple.com/videos/play/wwdc2019/248 and now users can see the screen line by line, by moving their fingers on the screen. That works fine.
However, users would also like to be able to use left-flick and right-flick to move to the previous or next line on the screen, and I haven't been able to make this work.
I can see that left-flick triggers accessibilityPreviousTextNavigationElement and right-flick triggers accessibilityNextTextNavigationElement, but I don't understand what these variables should be.
