RN Typedef redefinition with different types ('uint8_t' (aka 'unsigned char') vs 'enum clockid_t')

Description

I am currently building a project with React Native 0.67 and and Monterey MacOS, intel Chip.

I have tried about every possible solution, but yet, the problem persists.

The Problem is the following: after carefully following the instructions in react setup page to initialize a new app, when I execute the run-ios command I get the following error on my console, which seems to be related to Flipper:

** BUILD FAILED ** The following build commands failed: CompileC /Users/dr/Library/Developer/Xcode/DerivedData/Test-gxglauoeoglzeobdubkxzgziurmr/Build/Intermediates.noindex/Pods.build/Debug-iphonesimulator/RCT-Folly.build/Objects-normal/x86_64/SysUio.o /Users/dr/Library/Mobile\ Documents/com~apple~CloudDocs/2.\ Business/2.\ Software\ As\ A\ Service.nosync/socholar-native.nosync/Test/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’) (1 failure)

When I try running it from Xcode I get the following Error in RCT_Folly directory:

RN Typedef redefinition with different types (‘uint8_t’ (aka ‘unsigned char’) vs ‘enum clockid_t’)

When Runing with npx react-native run-ios

When running with Xcode in Time.h file

@yodarango in Time.h file you should do below changes at top:-

change this (TARGET_OS_IPHONE && (__IPHONE_OS_VERSION_MIN_REQUIRED < _IPHONE10_0))

to this (TARGET_OS_IPHONE && (__IPHONE_OS_VERSION_MIN_REQUIRED < _IPHONE12_0))

just you have to make 10 to 12 and clean the project, run it.

I hope it will solve your issue.

Same thing with react native 0.70.0
