Apple Mach-O Linker Error Group when using Cocoapods to add Firebase

I recently attempted to add Firebase to my application. Using Cocoapods I did a

pod init

and a

pod install

here is my Podfile:

    # Uncomment the next line to define a global platform for your project
# platform :ios, '9.0'

target 'A' do
  # Comment the next line if you're not using Swift and don't want to use dynamic frameworks
  use_frameworks!

  # Pods for A
pod ‘Firebase’
end

And when trying to build my application I get the following error:

Apple Mach-O Linker Error Group

I am using Swift 3.0

Any suggestions? Cheers

I found the solution just as I posted this question...

You must use the .xcworkspace file after pod install instead of .xcodeproj file.

In order to do so open the location of your project in finder, then open the .xcworkspace file with Xcode (this file was create by Cocoa Pods).

I just encountered the same issue with my new project, after trying many things, I finally solve my issue by updating my pods :

pod update
Installing Firebase 4.7.0 (was 4.1.1)
Installing FirebaseAnalytics 4.0.5 (was 4.0.3)
Installing FirebaseCore 4.0.12 (was 4.0.6)
Installing FirebaseInstanceID 2.0.7 (was 2.0.2)
Installing GoogleToolboxForMac 2.1.3 (was 2.1.1)

Clean your project from Xcode, also (if not sufficient) clear the Library -> Developer -> Xcode-> DerivedData folder and try to rebuild your project.

Try this instead in terminal:

  • git status
  • git branch
  • git add -A
  • git commit -m ‘’Your comment...’’
  • git push origin (Your branch name)
