Cannot Import Firebase Into Swift Class

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".

I am getting an error that says

"No such module 'Firebase'"

Any help would be greatly appreciated.

There are two ways to install Firebase: manually, and with CocoaPods.

I recommend using CocoaPods. In your Podfile, make sure you specify use_frameworks!:

platform :ios, "9.0"
use_frameworks!

target 'MyProject' do
 pod 'Firebase'
end

Then after you pod install and open the MyProject.xcworkspace, you should be able to use import Firebase.

edit by Jay:

If you are targeting OS X your pod file may look more like this

platform :osx, '10.10'
use_frameworks!

target 'MyProject' do
  pod 'FirebaseOSX', '>= 2.4.2'
end

For me it was this:

The Framework is called FirebaseAnalytics now and not Firebase.

The official documentation even has this wrong.

So after installing with CocoaPods (Firebase version 3.4.0) this works:

import FirebaseAnalytics

If you imported Firebase manually, update Framework Search Paths and Header Search Paths under your target's Build Settings so they include the Firebase frameworks.

When using the CocoaPods installation method, you can start by removing the project workspace file:
rm -rf MyProject.xcworkspace

Then, edit the Podfile to following, which will be automatically set for the latest version of Firebase:

use_frameworks! 
target 'MyProject' do
  pod 'Firebase/Core'
  pod 'Firebase/Database'
end

target 'MyProjectUITests' do
  pod 'Firebase/Core'
  pod 'Firebase/Database'
end

Finally, reinstall the pod

pod install

If you have added the firebase framework manually, delete it and add it again.Rebuild the project and it will work.

There seems to be a bug.This happens when you discard the changes.

For me, I had to make sure that cocoapods was updated to version 1.0.0.

Just run sudo gem install cocoapods, then clean project and pod install. Compiler should not complain anymore.

open terminal and type cd "drag and drop your project" Enter
type "pod init"
open pod file with xcode
under use_frameworks! type pod 'Firebase' pod 'Firebase/xxx'
back to terminal and type "pod install" 6.open your project folder and run xxx.xcworkspace

Those who are using swift 3 are welcome to try this. It worked for me.

My pod file:

platform :osx, '9.0'
use_frameworks!

target 'MyProject' do
  pod 'Firebase/Messaging'
  pod 'Firebase'
end

AppDelegate:

import FirebaseCore
import FirebaseMessaging

For me, I found that I wrote the line : (pod 'Firebase') in the wrong line in the pod file. you only need to find the comment : # Pods for projectName and then replace it with pods like: pod 'Firebase' or : pod 'Firebase/Auth'

In your Podfile make sure to have pod 'Firebase' in addition to your pod 'Firebase/Core'

After, :wq from vim and run a command pod update. Make sure to open .xcworkspace

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
