I am totally new to Firebase and building iOS apps. In Xcode 7, I am trying to import Firebase into my Swift class. In a swift file, I have typed \"import Firebase\".
So after spending hours and hours trying to fix this error I did the following and my life went back to normal
a) Went to my Podfile and changed pod 'Firebase', '~> 4.8' to pod 'Firebase/Core'
b) Then I went into my AppDdelegate changed from import Firebase to import FirebaseCore
If you were facing the same problem as me this solution will work for you
