Answer 1

Okay...So here is what solved my problem...

in App Delegate File:

#import "AppDelegate.h"
#import "DarkSkyAPI.h"
//#import "Credentials.h"

I had imported Credentials.h already in the DarkSkyAPI.m file in my project. Commenting out the extra import made the error go away!

Some things to mention and maybe help anyone in the future. @umairqureshi_6's answer did help me along the process, but did not solve it. He led to where I was able to dig out the info. I kept seeing AppDelegate and DarkSkyAPI files showing up in the error log and the information it was pulling from Credentials file was causing the error. I knew it had to be in one of these 3 files, so I immediately checked imports, because I remembered hearing that the .h carries all the imports from its .m file. Boom!
