Build Failed -- AppService.h file is not found

Question

I have already written Share Extension for ios. I have setup new Project where i am using same share Extension. I copied and paste the entire code and directory.

Do i need to include header in x-code. how to setup headers in that case.

Now, When i am trying to Build the project. it is giving me error .

**AppServices.h file is no found.**

Do i need to change any settings in X-code

Thanks
