i have a strange error when i was using firebase from google.
when i trying to init the Fire base setup the ref address for it using this code here
i also face the same issue . i delete the ccocoa pod and follow this link to install the firebase through cocoapod . after that i am able to solve this problem
Step 1 :- you need CocoaPods 1.0.0 or later
Step 2 :- Create a Firebase project in the Firebase console,
Click Add Firebase to your iOS app and follow the setup steps. If you're importing an existing Google project, this may happen automatically and you can just download the config file.click here
Step 3 :- Add the SDK
pod 'Firebase'
now Initialize Firebase in your app

Thanks
