I created a Bare expo app and tried to run react-native run-ios, I'm getting the following error:
Showing All Messages Build input file cannot be found: '/Users/user/Library/Developer/Xcode/DerivedData/testing-fxkbjuawpoifdbcjtioxmqmmeybm/Build/Products/Debug-iphonesimulator/appname.app/appname'
I tried making a fresh app but it didn't work.
I also tried to re-build the ios/directory with:
react-native upgrade --legacy true
I tried downgrading my react-native version so I could use the above command but I ran into issues.
Edit: Just for the record, the issue was that my computer's hard drive was almost full, and the app would not be able to compile completely. Yep, software engineering my friends...
