Catalyst + ReactNative: Typedef redefinition with different types ('uint8_t' (aka 'unsigned char') vs 'enum clockid_t') error when building for mac target

[0xmtn]

Description

I'm getting the following errors when building for mac. This is a default application, created via react-native init.
Error 1: Typedef redefinition with different types ('uint8_t' (aka 'unsigned char') vs 'enum clockid_t')
Error 2: ld: in /Users/jh/Documents/projects/VST/Trial3/ios/Pods/OpenSSL-Universal/ios/lib/libcrypto.a(cryptlib.o), building for Mac Catalyst, but linking in object file built for iOS Simulator, file '/Users/jh/Documents/projects/VST/Trial3/ios/Pods/OpenSSL-Universal/ios/lib/libcrypto.a' for architecture x86_64

React Native version:

MacOS: 10.15.4
Xcode: 11.4
RN: 0.62.0-rc.5
RN Cli: 4.8.0

Steps To Reproduce

Provide a detailed list of steps that reproduce the issue.

1. react-native init App
2. react-native run-ios - Works fine
3. Open App.xcworkspace, select mac as a target and clean build.

Expected Results

Application working on Mac too.

Snack, code example, screenshot, or link to a repository:

I commented out the following line in Time.h:

//typedef uint8_t clockid_t;
extern "C" int clock_gettime(clockid_t clk_id, struct timespec* ts);
extern "C" int clock_getres(clockid_t clk_id, struct timespec* ts);
#endif

Then tried to build again and the Error 1 disappeared but Error 2 still exists:

Should I do something for migration to build for mac?

I got it working by deleting Facebook Flipper and everything else related to it. Here are the steps to take:

1. Open Podfile and delete everything related to Flipper and FlipperKit. There are some post-install functions, delete them too.
2. rm -Rf Pods/*
3. pod cache clean --all
4. pod install
5. Open AppDelegate.m and delete everything inside DEBUG.

6. Hit Run and voila.

use_flipper!() function inside podfile
remove Pods and podfile.lock
