For code coverage, I upgraded to xcode13 and used extern to export the built-in function 'Gcov'. Xcode13 reported an error of "undefined symbol: __gcov_flush". I'm good on xcode12. Does anyone encounter this problem?
The specific error reports are as follows：
Undefined symbols for architecture x86_64: "___gcov_flush", referenced from: -[AppDelegate applicationDidEnterBackground:] in AppDelegate.o ld: symbol(s) not found for architecture x86_64 clang: error: linker command failed with exit code 1 (use -v to see invocation)
new llvm use __gcov_dump(). Place use new LLVM

I'm using xcode 13,
React-native version 0.64.2
Its working fine in Android but iOS I getting error
It builds with the following error:
Undefined symbols for architecture x86_64:
"_RCTRegisterModule", referenced from:
+[RNMixpanel load] in RNMixpanel.o
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
Undefined symbol: _RCTRegisterModule
Not sure if it's the same thing but for me my solution was an issue with the packages, they had s.dependancy as React when it should be React-Core. See here: https://github.com/facebook/react-native/issues/29633#issuecomment-694187116
You can manually change them to see if it works for you and then use the patcher as suggested to fix the libraries.

I am using RNCryptor from here. but cannot seem to get my app to compile correctly. I get the following errors in the log:

Can anyone tell me whats wrong here?
I would guess you built RNCryptor for ARM but you're building your application to run on the Simulator (i386).
The following is the detailed error message I got while compiling a OpenCV project. Please help me out. Thanks a lot!

The key there is "ld: symbol(s) not found for architecture x86_64". You're linking against a 32-bit library somewhere. What library, we have no idea, since you didn't include enough information.
