I'm testing out Catalina.. and one thing I noticed was i'm no longer able to use Expo/React Native's web feature, as its crashing with a "Watchman" error:
"
jest-haste-map: Watchman crawl failed. Retrying once with node crawler.
Usually this happens when watchman isn't running. Create an empty `.watchmanconfig` file in your project's root folder or initialize a git or hg repository in your project.
Error: Watchman error: query failed: synchronization failed: Operation timed out. Make sure watchman is running for this project. See https://facebook.github.io/watchman/docs/troubleshooting.html.​
"
Admittedly Expo web is still experimental.. but it seemed to break with Catalina. It kind of makes sense: Watchman probably hooks into some kernel stuff to achieve file watching.
