Firebase (4.0.0): Use of unresolved identifier FirebaseApp when installing FirebaseDatabase

Question

This is what happens:

• running on Xcode Version 7.3.1 (7D1014)
• pod 'Firebase/Core'
• import Firebase in the Class

unresolved on Database

Then I added the Database framework

• pod 'Firebase/Core'
• pod 'Firebase/Database'

unresolved on FirebaseApp

It seems that the 2 frameworks are in mutex mode. They cannot coexist.

I have tried everything: update, install, uninstall, recreate the project, recreate the workspace. All.

May you help me. Is there a bug on last Firebase release?

Answer 1

I had a similar issue.

Your import statement would be:

import Firebase

Make sure restart Xcode and to clean the build folder.

It's working for me & got rid of "Use of unresolved identifier FirebaseApp..." error

Update: For Swift 4.2: FirebaseApp.configure() does work. [FIRApp is renamed to FirebaseApp]

Answer 2

import FirebaseCore

Then you could use FirebaseApp.configure(). I'm using swift 4.
