Watchman Brew Package - iOS - React Native build

[rmjsantos]

I saw a similar post here requesting more brew packages Preinstall brew packages. But what I would like to know/request is if it’s possible to add watchman to iOS image.

I was having problems while building using React Native. I also found some guys having similar problems: https://stackoverflow.com/questions/54427035/circleci-react-native-xcode-10 and the post above.
Pros:

• It would make the build process gain at least 6 minutes.
  Every time we run brew install something, it will also run brew update.
  Is it something we can add in this images?

Hi there. If I’m remembering correctly, Watchman caused issues on CI since it causes test steps to wait for changes and never exit.

We don’t have any plans to add additional packages to the MacOS VM image. Installing it yourself is the best recommendation at this time.

You should be able to skip the brew update when installing watchman by running:

HOMEBREW_NO_AUTO_UPDATE=1 brew install watchman
