Here’s what worked for me on Mac.
- In terminal type
lldb path/to/build.app - In the opened debugger type
run --remote-debugging-port=8315. It should open a window of your app. - Open Chrome at
http://localhost:8315/ - Click on the name of the app. For example,
Webpack App. - If you don’t see anything in the opened tab, focus on the window of your app.
