ld: 91 duplicate symbols for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

So I understand that there are duplicates in my files and that's why I'm receiving this error (at least that what I think it the problem according to the ld). What I don't know how to do is reconcile the multiple files. I tried just removing Bolt entirely but that just made Xcode angry. REAL angry. Any help on how to solve this one? I'm pretty sure this is an easy one but I'm a noob.

Answer for future consultation:

What solved my issue in the end was starting from scratch and installing my dependencies via Cocoapods. It appears if you try to add a framework via a drag and drop and then later user= Cocoapods the previous framework will not be noticed by Cocoapods and Cocoapods will attempt to install that very same framework again.

So when using dependencies either only use drag and drop or only use Cocoapods from the get go. Do not try to mix and match.
