I’m taking a beginner’s course on iOS/Android development using React Native. My system is a 2018 Macbook Pro running Ventura 13.6.6. After installing the required developer tools I had over 110 GB of available space on the internal SSD.
I’m working with a simple “Hello World!” app. Each time I launch the Simulators, I see roughly 10 GB of available space disappear, as reported by the status bar of an open Finder window. When I close the simulators the space isn’t immediately recovered. On occasion, when I restart my machine I see some of it recovered, but there is a cumulative loss over just a few sessions. I have roughly 58 GB remaining. I’ve lost over 52 GB so far — all for one tiny, useless project! Where did it go? My progress will be cut short if I don’t find the cause and solution soon.
I have already deleted the Xcode cache. It was only reporting about 3.5 GB and deleting it didn’t save me any space. (It did solve a problem where the OS was reporting “unable to build simulator” for whatever reason.)
My steps are to:
- launch the iOS and Android Simulators
- run
npx react-native run-ios
to load the app into the iOS simulator - press
a
to open the app in the Android.
It’s the most reliable way I’ve found to get the apps to display in both without errors.
