I'm gonna ask your guidance/help for a problem I've been encountering for several days now,

I can create a new react native project (via npx react-native init projectName), but when I try to run it, either with npx react-native run-ios or yarn ios, I get the following error message:

The following build commands failed: CompileC /Users/user/Library/Developer/Xcode/DerivedData/Trickster-ejsutjhruuvmqjedsaarumhaquan/Build/Intermediates.noindex/Pods.build/Debug-iphonesimulator/RCT-Folly.build/Objects-normal/x86_64/SysUio.o /Users/user/Dev/Mobile/React
Native/Trickster/ios/Pods/RCT-Folly/folly/portability/SysUio.cpp normal x86_64 c com.apple.compilers.llvm.clang.1_0.compiler (in target 'RCT-Folly' from project 'Pods')

I've already cleaned yarn/npm cache, cleaned Xcode's DerivedData folder, even uninstalled node and react native from my computer, so I'm kinda lost tbh.

Here are my specs: MacBook Pro Mid 2014 with a 2.6GHz Core i5, 8Gbs of ram running macOS Monterey 12.2.1 npm version 8.5.2, 1.22.17 and Xcode 13.2.1.

Sorry in advance if I don't answer fast, I'm a bit ill atm so kinda occupying my time till I'm better

Try running Project from Xcode that will show you where problem exactly is

This problem can be for several reasons. To avoid going into so much explanation If the application worked at some point

1. Delete the app in the device and
   run yarn android or npm android or
2. delete the build folder and delete the app in the device and
   run yarn android or npm android or
3. on Android delete and reinstall the device then
   run yarn android or npm android

That's works for me
