macOS accessibility API on WebKit applications with AXTextMarker

Question

I need to access data from webkit applications such as Safari, Mail and maybe others. I can see in the Accessibility Inspector there is :AXTextMarker

Answer 1

Accessibility apps need to be added in System Preferences in the following section:

System Preferences -> Security & Privacy -> Privacy tab -> Accessibility (on the left)

Note that during development you need to include Xcode in this list if you are developing/running within Xcode.

I didn't test out your exact code, but I tested some comparable swift code and that worked fine provided Xcode was added in that spot in system preferences.
