After doing a \"Reset All Content And Settings..\" on the simulator the setting to enable using the web inspector in safari has disappeared, and I have no idea how to get it bac
In my case (macOS 10.14.3 and iOS 12.1 simulators), the setting isn't there, but is active by default. Open the simulator and you should see it in Safari under Develop.
Worked for me download new Safari:
IOS Simulator: 13.4
(Safari Technology Preview)
https://developer.apple.com/safari/download/
Safari Technology Preview
i needed to restart desktop safari. might help.
It seems that this option is not available in the simulated devices. Tip: If you want to connect the console from your desktop Safari, you will need the Technology Preview. the normal one does not discover the simulator (though it finds the real device normally)
