问题
I have a Swift project and have add a cocoapod, which is written in Objective-C. It has header and implementation files. From what I understand, to use/import these files into my Swift files, I need to add a bridging file.
I found this site describing how to do this manually, since the Objective-C files are already part of my project (from the cocoapod).

1.) Navigate to your project build settings and find the “Swift Compiler – Code Generation” section. You may find it faster to type in “Swift Compiler” into the search box to narrow down the results.
2.) Next to “Objective-C Bridging Header” you will need to add the name/path of your header file. If your file resides in your project’s root folder simply put the name of the header file there.
I don't have a Objective-C Bridging Header in that section and it doesn't appear you can add new entries there.
I'm using Xcode 7.3.1. Anyone have some idea how this should be done?
回答1:
Are you sure you looked at the correct Build Settings section, search with the keyword Swift compiler - General in the search field as describe below and then you can find it.
回答2:
You need to create the header file first. It is a regular Objective-C header file and should be named <Your app or framework name>-Bridging-Header.h. For any Objective-C headers you want Swift to know about add an import statement to the newly created header file. Then follow your previous steps.
There is also a hidden header that gets created for you called <Your app or framework name>-Swift.h. If you need to access any Swift classes from an Objective-C file import this header.
