I have tried to set up Firebase to work on Xcode using both the quick setup instructions and the manual alternate instructions on Firebase website.
When I used CocoaPods and followed the instructions on the quick setup page, I was able to import Firebase, but I was not able to reference Firebase inside the class. I got the error: Cannot call value of non-function type 'module' xcode
When I tried to set it up manually, I was not able to import or reference Fire base and I got the error: No such module 'Firebase'
