** BUILD FAILED **


The following build commands failed:
        CompileC /Users/omerkocer/tekvetek/ios/build/Pods.build/Debug-iphonesimulator/Pods-tekvetek_RN-OneSignalNotificationServiceExtension.build/Objects-normal/x86_64/Pods-tekvetek_RN-OneSignalNotificationServiceExtension-dummy.o /Users/omerkocer/tekvetek/ios/Pods/Target\ Support\ Files/Pods-tekvetek_RN-OneSignalNotificationServiceExtension/Pods-tekvetek_RN-OneSignalNotificationServiceExtension-dummy.m normal x86_64 objective-c com.apple.compilers.llvm.clang.1_0.compiler (in target 'Pods-tekvetek_RN-OneSignalNotificationServiceExtension' from project 'Pods')
(1 failure)

Tried this solutions but they are not worked for my case:

1.

pod deintegrate
pod install

2.

Allow Non-modular Includes In Framework Modules to YES in Build Settings tab.

3.

Delete all cached pods & pod install again.

I was getting this error after enabling use_modular_headers! in my pod file, it was needed by a few of my pods, causing the no module found error. As a result, instead of enabling modular headers for every pod, I switched it only for specific:

Disable use_modular_headers!
Add :modular_headers => true to each pod that needs it

pod 'POD_NAME', 'x.x.x', :modular_headers => true
