“React/RCTLog.h file not found” and “Bad receiver type 'int'”: Misplaced CocoaPods files to blame?

INTRO

Yesterday, I installed Cocoapods, Yarn, React Native, and other programs because I had the errors listed on this page, which are reproduced below. I have since installed Yarn and Java's JDK, though doing these has seemingly not changed the situation.

As also mentioned in the aforementioned post, this is code from a private GitHub repo which I inherited with little or no guidance from the people who worked on it. (I have also worked *far* more on Windows machines and, in comparison, have barely used any Macs.) Thus, this has been a time of rapid learning and implementing.

SUSPICIONS

I *suspect* this problem is easily solved by putting certain files in the right place, but what files should go where?
