How to Delete ShareExtension

I am making a diary app with swift2.

I added the App Extensions Share Extension to the app, but I misunderstood and it was different from what I wanted to do, so I would like to delete it.

In this case, is it all right to delete the target and the added folder normally?
Please let me know if you need to delete something else or if you need to change the settings.

Thank you for your cooperation.

I have also asked other questions, but I have not solved them, so I would like to ask you a question.
