I am testing the accessibility feature available in the Settings app called "Speak Screen". The help text in the Setting app states that swiping down with two fingers will cause the screen content to be spoken. However, I've been unable to get this feature to work. Every time I try the double finger swipe down, it behaves the same as the single finger swipe down gesture. Usually this manifests as making scroll views bounce. I've tried toggling the feature on and off, turning off Reachability, and rebooting my phone, but I can't get the speak screen gesture to work. If I access the speak screen feature from the "Speech Controller" button, then the screens content is spoken, as expected, so I know the feature is enabled. It's just the gesture that doesn't work. Is there something else I need to do to get this gesture to work? I don't want to tell my users to turn this feature on if I can't verify that the gesture will work with my app.

I have users who need to be able to hear the content of SwiftUI Text views. I have specified the .textSelection(.enabled) modifier for the text views. Adding this modifier causes a "copy" option to appear on long press, but it doesn't enable the visible selection of text, nor does it provide the "Speak" menu item that UIKit allows on text selection. Is the "Speak Selection" accessibility feature broken for SwiftUI Text views? I've found that there's another accessibility feature that does work (enabling the Speech Controller button for "Speak Screen"). Do I need to tell my users that Apple is deprecating the "Speak Selection" accessibility feature, and that they need to use the Speech Controller instead? Or is there something else I can do to my SwiftUI to get that feature to work?
