Multiple commands produce

[MuratDemirel]

I need to add a Unity project to my own project using @azesmway/react-native-unity. Source project using @azesmway/[email protected]
To do this, I copied the Unity folder into my project, installed the @azesmway/react-native-unity package using yarn, and installed the pods. When I tried to run my project in Xcode, I encountered 56 errors. All of them are related to repeated copying in the headers section of the react-native-unity pod. Some of the files are as follows:

Allocator.h
Array.h
Assemply.h
AssemplyName.h
Assert.h
Atomic.h
COM.h
ConditionVariable.h
Debugger.h
Encoding.h
Enum.h
Environment.h
Error.h
Event.h
EventImpl.h
Exception.h
FastReaderReaderWriterLockImpl.h

You need to completely remove everything that relates to Unity in XCode and only then install a new one according to the instructions

I've created a brand new react native project and did everything in the instructions step by step. Multiple commands errors fixed but now have i another errors.

all errors on the screenshot refer only to Unity - the plugin does not use such errors

@MuratDemirel how did you fixed it?

Just wanted to chime in here after I ran across this exact same error. The solution is to delete and extra Headers folder that might be in your ./unity/builds/ios/ folder. In my case i had a Headers folder that contained the exact same files as my ./unity/builds/ios/Unityframework.framework/Headers/* folder.

Deleting the duplicated header files fixed this issue for me. The ONLY thing in the unity/builds/ios folder should be the UnityFramework.framework folder.

Opening the project and selecting the pods project and then the react-native-unity pod, selecting "Build Phases" and then Headers->Public showed the extra header entries:
