Cannot Import Firebase Into Swift Class

Question

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.

Solution 1

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

Solution 2

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

Solution 3

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.

Solution 4

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

Solution 5

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.

I am still having trouble. I tried using your Podfile and I still cannot use import Firebase.

[David East]

Can you post your Podfile?

[Will Jackson]

Here is my Podfile: platform :ios, '9.0' use_frameworks! target 'The Lighthouse App 1' do pod 'Firebase', '>= 2.4.2' end

Building project solves the issue after reinstalling with new podfile.

LI Xinyang - I never thought of that! Damn. Thanks!

[Rabimba Karanjai]

Thanks. This did solve it for me. I was following the official one and that just wanted me to import Firebase. Upvoted

It depends on which sub-framework you are importing. If you are using the database, it is called import Firebase

Thanks for the configuration in OSX. However, I don't know how to do the configuration in code. In iOS, we do "FirebaseApp.configure()", but not in OSX.

[Tomasz Nazarenko]

I had to add to Header search Paths the path to the place where Firebase.h is. For example $(PROJECT_DIR)/Frameworks/Firebase

[Droid Chris]

This worked for me. Added pods to stage and test targets.

[Peter Zhao]

For the newest Firebase, import FirebaseCore

[Alan Silva]

I found the problem. I declared the pod 'Firebase' under the Tests Target... That might be the problem for others.

[Ever Uribe]

Yup can confirm it was import FirebaseCore if using the MacOS pods
