How to add missing files to WebDriverAgent project?

I am currently trying to build the WebDriverAgent project in Xcode. I uninstalled and reinstalled appium, but I notice my project structure is missing two files:

When I right click on these files and choose Show File Inspector, it doesn’t go anywhere, indicating these files aren’t misplaced, they just don’t exist. I believe I can simply create a config file and add it to the Configurations, but I have no idea how to add a .bundle file. What should be in there?

Can anyone send me an example of theirs, or tell me why my structure is missing them? Any help would be greatly appreciated.
